Systematic Wrongness II

As noted in my most recent post, David Brooks seems to make little distinction between government and household debt. We face, he tells us in another column, a “debt crisis,” by which I assume he means not a sovereign debt crisis (though he’s curiously unclear about this), but one caused simply by too much consumer debt. He writes,

Deficit spending in the middle of a debt crisis has different psychological effects than deficit spending at other times… In times like these, deficit spending to pump up the economy doesn’t make consumers feel more confident; it makes them feel more insecure because they see a political system out of control. Deficit spending doesn’t induce small businesspeople to hire and expand. It scares them because they conclude the growth isn’t real and they know big tax increases are on the horizon. It doesn’t make political leaders feel better either. Lacking faith that they can wisely cut the debt in some magically virtuous future, they see their nations careening to fiscal ruin.

How he knows all this is a curiosum. He cites no polls or surveys. Probably wise, since the ones I’ve seen (cited in my most recent post) show debt and deficits to be at best a minor concern of people and businesses compared to unemployment and sales.

If borrowing is the scourge Brooks thinks it is, he should be happy that it’s down:

 

But Brooks really has it in for government borrowing, since it apparently betokens big government (“a political system out of control”), of which Americanshe never stops telling usare skeptical. And that skepticism, he claims, translates into too little confidence to spend. Hence our troubles.

It’s very hard to see how Brooks’s narrative relates to reality. Government borrowing is what’s keeping us bobbing on the surface as opposed to plunging to the bottom. We see this when we decompose borrowing into its components:

 

(Source: Federal Reserve flow of funds data)

Government borrowing has risen while private sector borrowing has turned negative. Why is the increase in government borrowing a good thing? Because the source of our problem is a massive (and global) increase in desired savings, a liquidity trap in which people and businesses wish to hold their wealth primarily in liquid form rather than investing it productively. Government borrowing absorbs some of the excess savings, getting it into the economy rather than allowing it to sit idle.

U.S. government borrowing in these conditions has little effect on interest rates since, with demand depressed and factor utilization low, government borrowing doesn’t compete with private borrowing for scarce savings. At present government debt is just a relatively liquid substitute for money. Only as the economy recovers, and people and businesses are again willing to put their money in less liquid form, will government borrowing again compete for scarce savings with private borrowing, putting upward pressure on interest rates. That’s a concern, but it’s a problem we should want to have.

And as has been pointed out repeatedly by some, those with most at stake (and the most expertise) in U.S. government solvency, bond traders, are wholly unconcerned about a sovereign debt crisisthe prospect of which, Brooks claims, without evidence, is retarding private sector investment. Yields on all categories of Treasury debt are at or near record lows. Here are daily yields on all Treasury securities since 1990:

Treasury securities simply could not be the relatively liquid substitute for money they have become if bond traders doubted the future solvency of the U.S. government. Which is fortunate, since it affords us an enormous advantage in addressing the crisis. Low borrowing rates enable the government to do what the private sector currently can’t do: mobilize idle savings, putting it to productive use.

All of this should be uncontroversial. It’s a pity some members of the commentariat feel it necessary to spin a counter-narrative that has little basis in fact or reason.

Systematic Wrongness

It’s a curious thing when a commentator can’t seem to get anything right. Such was the case with David Brooks in a column several weeks ago. One can only take it as testimony to the mind-warping powers of ideology. Take this paragraph:

The Demand Siders don’t have a good explanation for the past two years. There is no way to know for sure how well the last stimulus worked because we don’t know what would have happened without it. But it is certainly true that the fiscal spigots have been wide open. The U.S. and most other countries have run up huge, historic deficits. And while this has helped save public-sector jobs, we certainly haven’t seen much private-sector job growth. It could be that government spending is a weak lever to counter economic cycles. Maybe monetary policy is the only strong tool we have.

Nearly every sentence in this paragraph is false or misleading. Let’s take it sentence by sentence:

1. “The Demand Siders don’t have a good explanation for the past two years.” The “Demand Siders” actually have the only explanation for the past two years. The bursting of the housing bubble and ensuing stock market collapse together eliminated about $13 trillion of wealth. These losses, through a thing called the wealth effect, reduced consumer demand by an estimated $500 billion per annum. The bursting of the housing bubble also caused residential construction to contract, which is estimated to have cost the economy another $500 billion in annual consumer demand. And then there was the bursting of a bubble in nonresidential real estate, which caused nonresidential construction to plunge, costing the economy another $150 billion in demand. The total loss in annual demand is thus perhaps $1.2 trillion. The effect of a demand shock (as some may recall from introductory economics) is downward pressure on output and prices (in contrast to a supply shock, which would put upward pressure on prices), which is what we’ve seen. (Numbers from Dean Baker.)

All evidence appears to be that, in depressed, deflationary circumstances, fiscal stimulus is effective whenever, and to the extent that, it’s been tried. In a statistical study of fiscal expansions during the 1930s, for example, Almunia, Bénétrix., Eichengreen, O.Rourke. and Rua found that “fiscal policy, where applied, worked extremely well…, whether because spending from other sources was limited by uncertainty and liquidity constraints, or because with interest rates close to the zero bound there was little crowding out of private spending.” Also, Adam Posen, who’s studied Japan’s “lost decade” of the 1990s and early 2000s extensively, observes, “Fiscal policy works when it is tried,” but in the case of Japan successful stimulus has repeatedly been thwarted by policy error—fiscal contractions that have undone the positive effects of stimulus. Posen writes that “when the Japanese government paid for fiscal stimulus in 1995, it got economic growth,” but “when it mistakenly pursued fiscal austerity in most of the remainder of the 1992-97 period, it got economic contraction”—a pattern repeated in the early 2000s.

And consider present-day experience in many Asian countries. David Pilling of the Financial Times writes:

However much Asians trumpet the value of parsimony, their governments have been as bold as any in opening the fiscal sluices. One reason is the bitter memory of the 1997 Asian financial crisis when the International Monetary Fund imposed fiscal austerity on several Asian countries. Those measures are now almost universally seen as a blunder that unnecessarily exacerbated economic misery… Unlike in the west, there is little debate in Asia about how well the stimulus worked. It has been spectacular. Asian output is well above pre-crisis levels. HSBC is predicting growth for Asia ex-Japan of 8.6 per cent this year. Rather than contemplating more stimulus, authorities are trying to cool things down.

I’ve shown the following graphs from Barry Eichengreen and Kevin H. O’Rourke in a previous posting, but let’s look at them again:

World Industrial Production

 

World Trade

 

World Equity Markets

 

Is it really hard to see that the current downturn was probably as bad as the Great Depression? That the reason we aren’t now in a second Great Depression is government actions—bank bailouts, but also demand-side stimuli such as expansionary fiscal and monetary policy—undertaken on an unprecedented scale in many countries? And that ending stimulus now, before recovery is assured, is a very bad idea?

Now, no one doing the math expected a $787 billion stimulus package over two years to fill the output gap. Let’s run through the math. This is very back-of-the-envelope, but back-of-the-envelope is appropriate here since we’re dealing with general magnitudes.

Okun’s law says that for every 1 percent increase in unemployment above full employment, GDP will be 2 to 4 percent lower than potential GDP. Let’s take the optimistic end of the range and assume that, for every 1 percent increase in unemployment above full employment, GDP is 2 percent lower than potential GDP. And let’s call full employment 5 percent (the CBO’s estimate of the NAIRU is 5.2 percent). Shortly after the stimulus was enacted, and before stimulus funds hit the economy, consensus forecasts of unemployment worsened to about 10 percent (and of course unemployment eventually reached 10.5 percent). So let’s say unemployment was forecast to be 5 percent above full employment. That means the output gap would be $1.4 trillion (10% x $14 trillion) during the first year of the stimulus and somewhat less than that the following year. To reduce unemployment by 1 percent should then require about $280 billion of additional annual GDP (since 2 percent x $14 trillion = $280 billion). To reduce it by 5 percent and close the output gap should then require about $1.4 trillion of additional annual GDP.

The stimulus bill spent $787 billion over two years. A little less than $100 billion of that was a patch of the AMT, so let’s call it $700 billion. And about $300 billion was offset by cutbacks and tax increases at the state and local level, so the net stimulus was about $400 billion. About two-thirds of the stimulus was spending and about one-third of it was tax cuts. Spending has higher multipliers than tax cuts; so let’s say the “spending multiplier” was 1.5 and the “tax cut multiplier” was 1. And let’s assume that half the money was spent the first year and half the second year. The addition to annual GDP over what it would otherwise have been would then be approximately:

(1.5 x $133 billion) + (1 x $67 billion) = $267 billion

If we get a 1 percent reduction in unemployment for every $280 billion of additional annual GDP, we get an approximately 0.95 percent reduction in unemployment after one year and about 1.9 percent after two years. If we factor in growth of the labor force, we might wind up with a reduction in unemployment similar to the estimates of Moody’s Analytics and the CBO for the fourth quarter of 2010, diagrammed below.

So the stimulus, according to this analysis, shouldn’t have been enough.

What would have been enough? My back-of-the-envelope math says $1.4 trillion (assuming no AMT fix). Taking out the $300 billion offset for cutbacks and tax increases at the state and local level, the net stimulus would be $1.1 trillion. The addition to annual GDP over baseline would then be approximately:

(1.5 x $367 billion) + (1 x $183 billion) = $733 billion

The unemployment reduction over two years should then be a little over 5 percent ($1.47 trillion ÷ $280 billion ≈ 5).

Interestingly, $1.4 trillion is the number reportedly proposed by the Treasury Department and very close to the one suggested by Christina Romer ($1.2 trillion) when the stimulus proposal was being formulated. The watering-down of these proposals by political considerations may be one of the tragedies of our age. (See Ray Lizza’s New Yorker piece; also this.)

These particular figures are not, of course, to be taken too seriously. The point is simply to illustrate that, using a textbook rule-of-thumb like Okun’s law, we can see that the stimulus ought to have been closer to the ballpark of $1.4 trillion than that of $787 billion. The stimulus, though obviously helpful (even a godsend considering the alternative), should have been insufficient to close the output gap and return the economy to full employment.

So the “demand siders” have a full—indeed the only plausible—explanation for the last two years. But that’s enough for sentence 1. Let’s go on to sentence 2.

2. “There is no way to know for sure how well the last stimulus worked because we don’t know what would have happened without it.” There’s no way to know for sure, in the strictest sense, how well the last stimulus worked. This is quite an uninformative statement. Obviously what we have are estimates, plenty of them, from reputable sources. For example, there are these from Moody’s Analytics and the CBO:


Macroeconomic Advisers and IHS Global Insight (and thus all three major macroeconomic forecasting firms) have produced similar estimates.

If Brooks or anyone knows reasons why the providers these estimates would be biased, they should explain. Republicans speak favorably of the CBO whenever its analyses support their policies. The head of Moody’s Analytics is former McCain adviser Mark Zandi.

It’s true some analyses suggest little or no positive impact from the stimulus. But these are a minority. The most prominent of them is perhaps Cogan, Cwik, Taylor, and Wieland, which estimates multipliers about a sixth as large as those of the above sources. But the reason for the difference appears to be the parameterization. In particular, fiscal expansions don’t happen in a vacuum, but evoke a monetary policy response, since the Fed at some point will have to raise interest rates to stem inflation. The quicker rates rise after a fiscal expansion, the larger the crowding-out effect will be, and the smaller the positive effect of the stimulus on output and employment. So a lot depends on how monetary policy is modeled. Moody’s, the CBO, Macroeconomic Advisers, and Romer/Bernstein all assumed relatively easy monetary policy over an extended period. Macroeconomic Advisers, for example, tells us:

Currently the nominal federal funds rate is pinned at nearly zero, and our favorite monetary rule suggests that it should be negative. Hence, when we prepared our analysis of ARRA, we explicitly assumed the Fed would not raise nominal interest rates in response to the stimulus because it wanted to encourage the largest possible impact on the economy. Furthermore, since the stimulus reduced slack in the economy and so put upward pressure on inflation (or prevented further disinflation), the real interest rate fell in our simulations. This is opposite the “normal” response of real rates in most reduced form models with an implicit (or explicit) monetary rule, and works to magnify the multiplier effects — as intended by the Fed.

In other words, because (a) the “correct” federal funds rate is negative, so that the federal funds rate will not likely rise for a considerable time, and (b) a fiscal expansion puts upward pressure on prices, the real interest rate

r = i - π   (real rate of interest = nominal rate of interest - inflation rate)

is destined to fall (or at least be lower than it otherwise would be). This creates a window in which a fiscal expansion is likely to be especially effective, i.e., with minimal crowding out.

By contrast Cogan, Cwik, Taylor, and Wieland tell us, “our analysis allows for the return to a stabilizing monetary policy after one or two years.” With possible deflation now on the horizon and the Fed making noises about engaging in unconventional monetary policy, it seems clear which parameterization was the more reasonable.

3. “But it is certainly true that the fiscal spigots have been wide open.” Not sure what Brooks means by “wide open.” If he means opened up to some degree, he’s right. There has been more federal spending. But the spigots haven’t been wide open if by “wide open” Brooks means unconstrained. The fiscal stimulus may or may not have been all that Obama could have gotten from Congress, but mathematically, as shown above, it wasn’t enough to close the output gap.

4. “The U.S. and most other countries have run up huge, historic deficits.” It’s true that the U.S. has run up huge deficits, but Brooks makes it appear that they’re entirely the result of the stimulus, which is anything but true. Much bigger contributors to the deficits are the Bush tax cuts (which Brooks supported) and the recession itself (i.e., the loss of tax revenues and automatic increases in, e.g., unemployment insurance and food stamps). Besides which, the whole point of the stimulus is to inject demand into a demand-starved economy. That by definition means deficit spending. Since stimulus is temporary, it doesn’t add significantly to long-term debt (unlike the Bush tax cuts that Brooks supported). Indeed by stimulating growth it improves long-run budgetary prospects over what they would otherwise have been.

5. “It could be that government spending is a weak lever to counter economic cycles. Maybe monetary policy is the only strong tool we have.” Most economists, including most “demand siders,” would agree that monetary policy is the best stabilization tool we have. Unless monetary policy is at the zero lower bound, in which case it’s largely ineffective. There’s nothing now to be done about short-term interest rates. They’re zero. And the Fed’s capacity to influence long-term rates appears to be minimal (see Krugman). Really this is the whole point behind arguments for stimulus. We’re in a liquidity trap, i.e., incomes and wealth are low, so demand is low and investment is unprofitable. That means that almost however much money the Fed puts into the economy (and the economy is now awash in cash), it doesn’t get used productively—a situation that will continue until demand recovers.

Is it really that hard to grasp that people and businesses don’t necessarily spend their money when (a) households are trying to recoup their lost wealth and (b) there are relatively few profitable investment opportunities?

How can demand recover? One way would be to leave the economy to its own devices (a “liquidationist” approach). After a long, savage depression during which vast amounts of capacity (including labor, i.e., lives) are wasted, wealth and incomes should start to recover. But luckily we have a better way. When demand is depressed, the government can step in and bolster demand through temporary deficit spending. It doesn’t adversely impact long-terms debt, since the spending is temporary, and in any case stimulating growth now makes future revenues higher than they would otherwise be. It’s not inflationary since, with demand depressed, pressure on prices is downward. There’s minimal crowding out of investment since in a liquidity trap there’s little competition for loanable funds. And the historical and contemporary evidence is that stimulus works when, and to the extent that, it’s tried.

Further down the column Brooks writes:

These days, debt-fueled government spending doesn’t increase confidence. It destroys it. Only 6 percent of Americans believe the last stimulus created jobs, according to a New York Times/CBS News survey. Consumers are recovering from a debt-fueled bubble and have a moral aversion to more debt.

(People, of course, believe the stimulus failed because unemployment is nearly 10 percent. And they don’t know that absent the stimulus unemployment would almost certainly be much worse.)

Brooks oddly conflates government debt and household debt. It’s all just “debt.” And Americans now have a “moral aversion” to it and therefore believe spending in general should stop. It’s unclear when Americans got this religion. They showed no “moral aversion” to debt during the housing bubble, or, as far as I can tell, ever:

And somehow now, in a depressed economy, when deficit spending is appropriate (for once), they suddenly have a “moral aversion” to it? To the extent that Americans have a “moral aversion” to deficit spending, I suspect it’s because commentators and politicians (many of whom supported the policies that caused the debt problem) keep nattering on and on about it, and falsely imply that temporary stimulus is a major contributor to long-term U.S. debt.

But actually debt and deficits aren’t major concerns of Americans. We can look at polls:

(See also this.)

The fact that Americans are now deleveraging has an obvious explanation: they have no choice, moral or otherwise:

 

Brooks is concerned about confidence which he claims government debt destroys. And what about mass unemployment? Does that affect confidence? Most Americans don’t understand that there’s a short-term tradeoff between deficit spending and unemployment. But if given their choice between policies that lower deficits and policies that lower unemployment, which would they choose? I wonder.

Still further down the column, Brooks writes:

You can’t read models, but you do talk to entrepreneurs in Racine and Yakima. Higher deficits will make them more insecure and more risk-averse, not less. They’re afraid of a fiscal crisis. They’re afraid of future tax increases. They don’t believe government-stimulated growth is real and lasting. Maybe they are wrong to feel this way, but they do. And they are the ones who invest and hire, not the theorists.

Yes, you can talk to entrepreneurs. And here’s what they say:

 

The National Federation of Independent Business (NFIB) has regularly surveyed small business opinion since 1973. The above statistics are from its June report. Here are the same statistics over a longer period:

 

Brooks writes as if he’s surveyed business opinion and is reporting his findings: that their main concerns are government debt and taxes. Obviously he’s done nothing of the kind. Taxes are a perennial concern of businesses, to be sure, though they appear to be less of a concern now than theyve been over most of the last 25 years. And currently theyre superceded by sales, as one would expect when consumer demand has plummeted. Government debt, on the other hand, seems not to be on the radar at all.

Though businesses have their special interests, the bottom line is clear. The report comments:

Unfortunately, Washington, D.C. and many state legislatures seem determined to undermine any economic forward momentum for small business owners. And even though small business owners continue to plead their case for policies that will help foster economic growth, many lawmakers are unwilling to listen. Small business owners keep saying that poor sales (“It’s the consumer, stupid!”) is their most pressing problem and the reasons they aren’t interested in expanding are due to current economic conditions and the political climate. Unfortunately, Congress is fixated on credit and special favors for unionized firms, and that won’t sustain or support faster growth.

Yet Brooks is adamant that businesses are concerned about government debt. Why? Does he so strongly believe that they must feel this way that he went ahead and asserted it without bothering to check whether it was true?  Curious, in any case, that entrepreneurs would be so concerned about government debt when those with most at stake in U.S. government solvency, bond traders, aren’t. The ten-year Treasury rate is now (August 10) 2.78 percent. Bondholders are demanding a 2.78 percent return to lend money to the U.S. government for ten years!

In an apparent attempt to seem empirical, Brooks cites a study by Lauren Cohen, Joshua Coval and Christopher Malloy of Harvard that found that increased government spending in certain congressional districts dampened corporate sector investment and employment. Brooks, invoking his theme of epistemic modesty, says, “You wish somebody could explain that one to you before you pass on more debt burdens to your grandchildren.” There are three problems with Brooks’s reference to the study. First, the study is at the local (congressional district) level, not the national level, which is the level relevant to the stimulus debate. Second, it uses data from the non-liquidity-trap years of 1968-2008 and thus doesn’t pertain to conditions relevant to stimulus in a depressed economy, which is the question we now face. And third, and most importantly, what the study actually finds is consistent with “demand siders’” views about stimulus. The authors write:

...the coefficient on firms in states with low unemployment is -0.016. For firms in states with high unemployment, the coefficient is 0.024 larger, which is sufficient to reverse the effect entirely (even considering the main effect of High Unemployment itself). This result can be interpreted as providing evidence consistent with the view that government stimulus crowds out private sector employment when the economy has little slack in the labor market, but does not when the economy is experiencing significant slack in the labor market” (italics added). 

This, of course, is an argument most stimulus advocates would make. Indeed the authors note, “…consistent with Keynes’ view that  crowding out should only occur under conditions of full employment, we find a weaker firm response to spending shocks when state-level employment is at or below its long-term historical average.” What they find, as noted in the above quote, under conditions high unemployment is a reversal of the crowding out effect they find under conditions of greater vibrancy.*

It’s not that the study supports Keynesian stimulus. The data don’t include the depressed economic conditions in which the question of Keynesian stimulus arises, so it doesn’t address the issue. Either Brooks didn’t read the article and/or he’s unfamiliar with the arguments for stimulus. I suspect both.

Modern-day Keynesians argue that we should spend when the economy is depressed and save when it’s healthy. (It’s not very complicated.) That prescription was followed by Keynesian-like economists who held power in the early 1990s. The result, by decade’s end, was surpluses as far as the eye could see, soon to be replaced by deficits as far as the eye could see, thanks to massive tax cuts supported by Brooks. Brooks and other conservatives, by contrast, apparently believe that we should save when the economy is depressed and spend when it’s healthy. This is simply not economics. You will not find this prescription in any macroeconomics textbook, including those by conservative economists. 

Brooks, an all-purpose pundit, must opine about the economy, though he obviously lacks a background in the subject. He finesses the latter fact by fitting economics to his narrative, the narrative that is his livelihood. What is this narrative? It seems to combine two main themes: that Americans are skeptical of big government, and that social reality is too complex for policy makers to adequately grasp and so their grandiose policy schemes tend to fall short. Most Americans lack Ivy League credentials or high IQs. But their skepticism of big government, and of the grand schemes of policy makers, shows a deep native wisdom. (Or at least it might be if they had it.)

So how should government proceed? Well, some modest policy-making is okay. Brooks’s advocacy of that makes him a “moderate” when compared to some of his right-wing brethren. But the third leg of Brooks’s narrative is the market. Policy makers, with their high IQs and impressive academic credentials, tend to be overconfident in their abilities to manage society. So intellectual modesty bids that we not tinker too much with the institution (the market) that is the fount of modernity and that centuries of evidence tell us embodies a collective wisdom vastly greater than that of any individual woman or man. 

The only problem with this is that that’s not what centuries of evidence tell us. Much of the last 300 years has been economically highly unstable, with booms, busts, bubbles, market failures, and depressions the most prevalent manifestations of our dynamic capitalist economy. It’s only in the post-World War II era, as the government has taken a bigger role in the economy, that large-scale instability has been more or less tamed.

One might have thought the third leg of this three-legged stool was knocked out in the fall of 2008. But now that the stimulus and other measures have rescued the economy from the abyss (though not restored it to full health), it becomes possible again to imagine, with appropriate blinders on, that the “market” is the self-correcting marvel people thought it was, that the insights gained over 70 years about the potential positive role government might play in depression-like circumstances don’t apply, and that all that’s needed to bring the economy back to health is some tinkering around the edges to raise confidence. But what Americans need isn’t “confidence.” (Confidence to what? Spend what they don’t have? Yes, that would be helpful.) What they need is income. And they’re not going to get it if we blunder into a Japanese-style lost decade. Brooks’s narrative is a force compelling us to do just that.

*The authors point to a likely “crowding out” effect—not crowding out in the traditional sense of increased competition for loanable funds driving up interest rates (since here we’re just talking about reallocations of government spending from one congressional district to another, not an absolute increase in government spending), but the possibility of increased competition for factors of production. One might reasonably expect government spending to entail such increased competition when labor markets are tight.

Four Instruments

Michael Lewis’s new book, The Big Short, is a story of discovery—discovery by a small group of investors (Lewis estimates there were “more than ten, fewer than twenty” such people in the world) that the financial world was perched on a precipice and about to crash violently to the rocks below. And they subjected their insight to an empirical test: they bet on it. (And won, of course.)

Some observers called the housing people; some noted the absurdity of the mortgage products (alt-A, no-income, option ARM, etc.) being pedaled to naïve homebuyers in the subprime mortgage market. But few perceived the extent to which institutional investors and even Wall Street itself had taken a long position in the subprime mortgage market. And it was no ordinary long position, but one multiplied many times over by derivatives, e.g., synthetic CDOs (many of these stamped “triple-A”). And it was a position made all the bigger by leverage, with investment banks allowed debt-to-equity ratios as high as 40-to-one.

A recurrent question in Lewis’s book is who was on the long side of the bets his protagonists (who were principally hedge fund managers Steve Eisman, Michael Burry, Charlie Ledley, Jamie Mai, and several associates) were making. That is, if they were shorting the subprime mortgage market—by buying credit default swaps on mortgage-backed securities and CDOs—someone had to be on the long side. (And they didn’t believe it could be the “smart money” firms selling them the credit default swaps, i.e., Goldman Sachs, Deutsche Bank, etc.) Discovering who that was, and how the financial system had become so extraordinarily fragile is the story of Lewis’s book. The drama is punctuated by various revelatory moments where one or another of Lewis’s protagonists peels back another layer of the mystery, perceiving some previously hidden aspect of the financial instruments and practices that had evolved to render the system so vulnerable. The end-result is a rather eye-opening view not just of the financial crisis but of human nature.

Not a complete explanation, but a significant degree of illumination, of the financial crisis, arises from consideration of four financial instruments that figure prominently in Lewis’s story:

1. Mortgage-backed securities (MBS)
2. Collateralized debt obligations (CDOs)
3. Credit default swaps (CDS)
4. Synthetic collateralized debt obligations (synthetic CDOs)

Let’s take each in turn.

1. Mortgage-backed securities (MBSs). Mortgage-backed securities are simple. They’re like mutual funds, only rather than stocks pooled together to yield dividends and capital gains or losses, they’re mortgages pooled together to yield interest and principle. How to securitize mortgages was a vexing problem in the financial industry for years. The problem, apart from default risk, was prepayment risk—the risk that falling interest rates might compel mortgage-borrowers to refinance, leaving lenders with prepaid mortgage balances to reinvest at now-lower rates.

So, the question was how to structure pools of mortgages in a way that would make them marketable to investors on a large scale. The answer was tranches, i.e., dividing investors into classes according to willingness to absorb default and prepayment risk. In the “senior tranche”—about 80 percent of investors in a security—investors would get the lowest risk and lowest return. In lower tiers they would get higher risk and higher returns. And in the lowest tranche of all, the mezzanine level, they would get the highest return but also the preponderance of default and prepayment risk. So in the event of default by some portion of mortgage-borrowers whose loans are included in an MBS, mezzanine level investors would be fully cleaned out before losses start to accrue to investors in the next higher tranche, and so on.

The ratings agencies generally stamped securities marketed to senior tranche investors as triple-A (i.e., as safe as Treasury bonds), those marketed to mezzanine level investors as triple-B, and those marketed to investors in between at intermediate grades. Tranching thus enabled the creation of a liquid market in mortgage-backed securities.

Nothing necessarily very amiss here. Arguably this is Wall Street performing its legitimate function of efficiently aggregating and allocating savings and distributing risk. Of course, when MBSs are backed largely by subprime loans, that’s a problem. But most MBSs werent backed by subprime loans. It seems that if Wall Street ingenuity had extended no further than MBSs, the catastrophe might have been averted.

2. Collateralized debt obligations (CDOs). One step beyond securitization of loans is securitization of securitizations of loans. This is essentially what a collateralized debt obligation (CDO) is—a sort of fund of funds, but rather than pooling together different mutual funds or hedge funds, it pools together different asset-backed securities, e.g., different mortgage-backed securities.

As Lewis explains,

Its logic was exactly that of the original mortgage bonds [or mortgage-backed securities]. In a mortgage bond, you gathered thousands of loans and, assuming that it was extremely unlikely that they would all go bad together, created a tower of bonds, in which both risk and return diminished as you rose. In a CDO you gathered 100 different mortgage bonds—usually, the riskiest, lower floors of the original tower—and used them to erect an entirely new tower of bonds.

So why create a new configuration of securities that were already on the market? Well, the problem with ordinary mortgage-backed securities is that they

…are too near the ground. More prone to flooding—the first to take losses—they bear a lower credit rating: triple-B. Triple-B-rated bonds were harder to sell than the triple-A-rated ones, on the safe, upper floors of the building… there were huge sums of money to be made, if you could somehow get them re-rated as triple-A, thereby lowering their perceived risk, however dishonestly and artificially. This is what Goldman Sachs had cleverly done. Their—soon to be everyone’s—nifty solution to the problem of selling the lower floors appears, in retrospect, almost magical. Having gathered 100 ground floors from 100 different subprime mortgage buildings (100 different B-rated bonds), they persuaded the rating agencies that these weren’t, as they might appear, all exactly the same things. They were another diversified portfolio of assets! [p. 73]

So a key motivation behind repackaging mortgage-backed securities into collateralized debt obligations was simply to make money. Since triple-B MBSs were “too near the ground” and thus unattractive to investors, investment banks packaged them into CDOs, making an argument about “diversification of risk” that convinced ratings agencies to rate them A, double-A, or triple-A. The result was a new higher-grade product confected entirely of lower-grade product.

One could argue that CDOs nevertheless embody the same idea as MBSs, and thus, like MBSs, increase the efficiency of intermediation—only on a grander scale. But Lewis’s protagonists didn’t see it that way:

A CDO, in their view, was essentially just a pile of triple-B rated mortgage bonds. Wall Street firms had conspired with the rating agencies to represent the pile as a diversified collection of assets, but anyone with eyes could see that if one triple-B subprime mortgage went bad, most would go bad, as they were all vulnerable to the same economic forces. Subprime mortgage loans in Florida would default for the same reason, and at the same time, as subprime mortgage loans in California.

And they calculated that to “wipe out, entirely, any CDO made up of triple-B bonds, no matter what rating was assigned it,… all that was needed was a 7 percent loss in the underlying pool of home loans” (p. 129). Thus they concluded that the CDOs were simply “fraud.” But since “the market appeared to believe its own lie,” and thus “charged a lot less for insurance [credit default swaps] on a putatively safe double-A-rated slice of a CDO than it did for insurance on the openly risky triple-B-rated bonds,” it was “also a stunning opportunity.”

3. Credit default swaps (CDSs). Lewis’s protagonists shorted the subprime mortgage market primarily by buying credit default swaps (CDSs) on MBSs and CDOs. Credit default swaps are insurance contracts on bonds. If you own a bond and want to hedge your risk, and someone is willing, for a fee, to assume that risk, then it’s hard to see a problem with purchasing a credit default swap. In this function a credit default swap is a straightforward insurance product.

But Lewis notes two other ways of looking at credit default swaps. First, since purchasing one requires no financial exposure to the underlying asset (unlike with ordinary insurance), and since credit default swaps are tradable in secondary markets (again, unlike standard insurance contracts), credit default swaps can be instruments of pure speculation.

And secondly, and more bizarrely, one could think of a credit default swap

…as a near-perfect replica of a subprime mortgage bond [or mortgage-backed security]. The cash flows of Mike Burry’s credit default swaps replicated the cash flows of the triple-B-rated subprime mortgage bond that he wagered against. The 2.5 percent a year in premium Mike Burry was paying mimicked the spread over LIBOR that triple-B subprime mortgage bonds paid to an actual investor. The billion dollars whoever had sold Mike Burry his credit default swaps stood to lose, if the bonds went bad, replicated the potential losses of an actual bond owner. [p. 75]

In other words, through creation of these insurance products that, again, (a) can (like MBSs and CDOs) be traded in secondary markets, and (b) require of the buyer no financial exposure to the insured asset, a kind of clone security is generated. For every MBS or CDO, there can be an analogous CDS with exactly the same financial characteristics, i.e., the same risk and same payoff triggered by the same events. This is a curious, even eerie, property for a financial asset to have, since, unregulated as they are, any number of these can be generated from only one underlying real (non-derivative) security. So the original MBS provides a kind of genome from which financial engineers can generate any number of copies. This opens up a new universe of financial activity.

And how well do credit default swaps square with Wall Street’s storied function of aggregating and allocating savings and efficiently distributing risk? Obviously, purchasing insurance on an asset one doesn’t own and that one can sell to another party, preferably when its price has risen, has little to do with hedging risk. Still there’s a long-shot argument to be made that selling vast quantities of credit default swaps, as AIG did, gains for the seller greater financial wherewithal for its other, more orthodox, insurance activities. (As I say, it’s a long-shot argument.) But it’s in their odd property of mimicking mortgage-backed securities that credit default swaps depart furthest from any conventional notion we may have of finance and its role in the economy.

4. Synthetic collateralized debt obligations (Synthetic CDOs). Here’s where the story takes its oddest turn. Since credit default swaps mimic the asset-backed securities they insure, in the sense that the parties on each side of the transactions transfer the same “premiums,” incur the same risk, and realize the same payoff or loss depending on the outcome of the reference event, logically one could combine credit default swaps, rather than MBSs, into one security and call it a CDO. That would be a synthetic CDO. Thus a synthetic CDO is a CDO composed not of asset-backed securities (and thus loans, ultimately), but of credit default swaps (which are just insurance contracts, not loans at all).

I mentioned revelatory moments—moments where one or another of Lewis’s protagonists peals off another layer of the mystery of who was on the long side of their bets. I’ll quote in full what is perhaps the book’s most dramatic passage (italics in original). Steve Eisman is finally face-to-face with someone on the other side of his bets, a synthetic CDO salesman named Wing Chau. Chau says:

I love guys like you who short my market. Without you I don’t have anything to buy.

Say that again.

That’s when Steve Eisman finally understood the madness of the machine. He and Vinny and Danny had been making these side bets with Goldman Sachs and Deutsche Bank on the fate of the triple-B tranche of subprime mortgage-backed bonds without fully understanding why those firms were so eager to accept them. Now he was face-to-face with the actual human being on the other side of his credit defaults swaps. Now he got it: The credit default swaps, filtered through the CDOs, were being used to replicate bonds backed by actual home loans. There weren’t enough Americans with shitty credit taking out loans to satisfy investors’ appetite for the end product. Wall Street needed his bets in order to synthesize more of them. They weren’t satisfied getting lots of unqualified borrowers to borrow money to buy a house they couldn’t afford, said Eisman. They were creating them out of whole cloth. One hundred times over! That’s why the losses in the financial system are so much greater than just the subprime loans. That’s when I realized they needed us to keep the machine running. I was like, This is allowed?” [p. 143]

Eisman hadn’t imagined that the investment bankers would have taken the credit default swaps he and others had purchased and packaged them into CDOs—that his shorting of the subprime market was adding more fuel to the inevitable fire.

Goldman Sachs and Deutsche Bank had been selling Eisman credit default swaps for years. Initially Goldman and Deutsche had intermediated between Eisman and (unbeknownst to Eisman) AIG, a situation that ended in 2005 when AIG realized it was selling many credit default swaps on MBSs backed largely by subprime loans. (Unfortunately at that point it was too late. The seeds of AIG’s destruction were sewn.) Now Goldman and Deutsche were intermediating between Eisman and synthetic CDO confectors like Wing Chau.

And why would the investment banks and CDO confectors have created these new instruments, synthetic CDOs? Because mortgage lenders had run out of “Americans with shitty credit” to lend to and thus the “raw material” with which to generate the mortgages needed to create the MBSs. The thing is, at this point it didn’t matter. They didn’t need more “Americans with shitty credit.” They just needed the credit default swaps, which as noted earlier mimic MBSs and could be regenerated, on the basis of those MBSs, any number of times over. And from the CDSs they could confect CDOs, which likewise could be regenerated using CDSs (like those Eisman and others were bringing into existence through their shorting activity) any number of times over. Since the synthetic CDOs seemed diversified, and ratings agencies had neither the incentives nor the capabilities to properly assess their risk, they tended to be certified A, double-A, and triple-A. And so these assets could be passed to institutional investors in exchange for portions of the colossal quantities of savings that had accumulated around the globe.

There’s no possible pretense that synthetic CDOs somehow enhance Wall Street’s storied function of efficiently aggregating and allocating savings and distributing risk. The money investors pay for synthetic CDOs is apportioned between synthetic CDO salespersons and investment banks. Money received by purchasers of CDOs is just “premium” payments from the owners of the credit default swaps. Period. No money is lent to anyone. No risk is hedged. It’s just gambling, straightforwardly. The mortgages are just a physical reference, like horses in a horse race or a ball on a roulette wheel.

The moral of the story is that humans as a whole are unscrupulous and generally will go wherever they can go. And they arent necessarily very knowledgeable about the landscape into which they venture or how their activities shape it. Development of the derivatives products described here was, in a micro context, rational, as was that of the subprime mortgage products devised in the mortgage market. But of course these instruments helped create a catastrophe. Human ingenuity and energies are wonderful things. But to benefit from them, we need to subject them to the scrutiny of our rational self.

Where the Economy Is and Where it's (Apparently) Going

There are two sorts of downturn: cyclical downturns, where businesses expand perhaps a bit much, are stuck with excess capacity, and then have to lay off workers. It’s not pleasant. Growth slows. Unemployment rises. Living standards fall. But the economy doesn’t depart very far from its long-term upward trajectory. Recovery arises when the central bank sets short-term interest rates sufficiently low that investment is again profitable. Employment and incomes then rise and growth resumes.

A downturn caused by a financial crisis or asset market collapse is different. Wealth is wiped out on a massive scale. As wealth-holders try to recoup their liquidity positions and honor obligations by deleveraging, asset prices fall further, vaporizing still more wealth, and so on. It’s a downward vicious cycle, like falling off a cliff. Merely lowering short-term interest rates won’t stimulate much investment since consumer demand is low and in any case credit will be scarce if many businesses and households are of questionable solvency. The economy can be awash in liquidity, as in fact it is, thanks to the Fed, and this no doubt helps on the margin. But if profitable investment opportunities are scarce because of low consumer demand, economic activity will remain minimal. Recovery awaits restoration of previous wealth levels, inherently a very slow process.

How bad is the downturn? All early indicators suggested a crisis every bit as bad as, if not worse than, the Great Depression. Charts provided by Barry Eichengreen and Kevin H. O’Rourke make this plain:

World Industrial Production

 

World Trade

 

World Equity Markets

 

The key difference between now and the 1930s is that in the current episode a recovery began around 12 to 14 months in (around April to June of 2009). Why? Because of government action: massive stimulus in many countries, bailouts of financial institutions, and unprecedentedly expansionary monetary policy. We’ve learned at least something from the past.

Kenneth Rogoff and Carmen Reinhart, in their exhaustive historical survey of financial crises, find that in the aftermath of such crises unemployment on average rises a full seven percent over an almost five-year period, that output falls on average nine percent over a two-year period, and that government debt rises on average 86 percent, in the post-World War II period, largely because of a collapsing tax base and government stimulus efforts. By those standards, our recovery is ahead of schedule, with unemployment rising just 5.6 percent over a little less than two years (from 4.8 percent in April 2008 to its probable peak of 10.4 percent in February 2010), and output growing since last summer after contracting for one year.

The reason for our relatively rapid recovery is, of course, government action, notably the stimulus. All three major macroeconomics forecasting firms, IHS Global Insight, Macroeconomic Advisers, and Moody’s Economy.com agree that the stimulus played a major role. (See this, this and this.) The CBO’s projections of jobs created by the stimulus are as follows (but note the tapering off toward the end of 2010 as the stimulus fades away):


Historical studies (see, for example, this) demonstrate that stimulus is, well, stimulative. Theoretical studies (e.g., this and this) show plausible mechanisms whereby stimulus is especially expansionary when, as now, the federal funds rate is zero.

Common estimates of the multipliers of various kinds of spending and tax cuts are as follows (these provided by Moody’s Economy.com):

 

Each term represent the one-year dollar change in GDP for a given dollar reduction in federal tax revenue or increase in spending. Note the estimated multiplier for extension of unemployment benefits, 1.61, which means that for each dollar of unemployment benefits, GDP is expected to rise by $1.61 over the following year. (And for clarity, a multiplier larger than 1 means there’s no net crowding-out effect within one year of the injection, though there may be in future years as the stimulative effects taper off.) Plausibly this is the best stimulus there is, in part because the multiplier is big, but also because it’s easy to implement and the money gets into the economy fast.

Republicans in the Senate, however, are blocking renewal of unemployment benefits on the grounds that it will worsen our long-term fiscal problems. So we have the spectacle of the very people who, when they entered the White House in 2001, were bequeathed surpluses as far as the eye can see and quickly, through tax cuts, wars, and (of all things) an unfunded Medicare entitlement, turned them into deficits as far the eye can see, now claiming that any additional stimulus—which in contrast to their tax cuts has a minimal impact on deficits and in the long run would improve federal finances since nothing enhances revenues as effectively as growth—is unaffordable. Its enough to make one scream.Yet its just part of a broader, inexplicable, global policy decision to nip successful stimulus in the bud before its objective has been achieved. As David Leonhardt writes in his June 29th column: “The world’s rich countries are now conducting a dangerous experiment. They are repeating an economic policy out of the 1930s—starting to cut spending and raise taxes before a recovery is assured—and hoping today’s situation is different enough to assure a different outcome.” (The pattern is familiar from history. Why, during severe downturns caused by financial crises policymakers, like FDR in the 1930s, Japan in the 1990s and 2000s (see Posen), and European leaders today, seem ineluctably drawn toward withdrawal of stimulus before recovery is complete is a topic for political science research.)

Republicans claim that unemployment benefits encourage unemployment is to some extent true, but it’s a small effect (see Krugman). And obviously when macroeconomic forces have thrown millions of people out of work, so that for every job vacancy there are five applicants rather than the usual one, tinkering with incentives will have little effect on the overall unemployment problem. On the other hand, stimulating the economy, through such measures as extending unemployment benefits, will.

But Republicans aren’t actually serious about the long-term fiscal problems. The latter are summarized in this chart provided by the Center for Budget and Policy Priorities, based on CBO data:

 

Our long-term fiscal problems largely concern health care costs. Yet the first serious effort to start to get control of health care costs (the Patient Protection and Affordable Care Act) was demagogued by Republicans as “cutting Medicare” (this from the party that opposed Medicare when it was proposed and tried to cut it sharply in the 1990s).

Some Republicans surely aren’t idiots and know the facts about stimulus. (Surely people on their staffs read the CBO reports or have availed themselves of the recent testimony of former McCain advisor Mark Zandi.) Thus I conclude the Republicans are trying to sabotage the recovery. Why? Because they think it’s in their political interest to do so. And yes, this probably means years of recession, many broken families, and many broken lives. But if they can get the blame for it placed squarely where it doesn’t belong, on Obama, it’ll be good for them politically. Cynical, yes, but the political incentives are what they are.

Some Reality about Deficits

First, a chart from a recent G-20 report:

 

The notable item here is revenue loss, i.e., lower tax revenues and higher transfer payments (e.g., unemployment insurance) arising from the economic downturn. Note also the relatively minor item, fiscal stimulus.

Next, from the Center for Budget and Policy Priorities, a diagram based on CBO data projecting the sources of U.S. federal deficits over the next ten years:

So, to be clear, far and away the biggest contributor to our fiscal woes is the Bush tax cuts. Nothing comes close. The second biggest contributor is the economic downturn and consequent loss of revenues. The third biggest contributor is the wars in Iraq and Afghanistan, another Bush policy. The fourth biggest contributor—and hardly worth mentioning in this context—is the fiscal stimulus. And the fifth biggest contributor—and definitely not worth mentioning in this context—is the TARP.

I would divide the sources of deficits into three categories (in order of decreasing importance):

1. Permanent spending and/or taxation decisions, e.g., entitlement programs or permanent tax cuts (which most of the Bush tax cuts threaten to become).

2. General economic conditions.

3. Temporary spending and/or taxation decisions, e.g., wars, the stimulus, and the TARP.

The effects of these three sources of deficits on the long-term fiscal outlook are not straightforward. In particular, temporary deficit spending can, in certain circumstances, improve our long-term fiscal position through its positive effect on general economic conditions. Those circumstance exist particularly when interest rates are historically low, as now, so that there’s no possibility of crowding out of private investment and when demand is severely depressed, as now, so that there’s no near-term prospect of inflation.

There’s a (I suppose) human tendency to attribute fiscal conditions exclusively to decisions of politicians, neglecting the often larger role of background economic conditions. The irony is that imposing austerity and cutting stimulus, as seems to be in the cards these days, will almost certainly worsen our long-term fiscal position. So why would this be happening? Well, because (a) it’s evidently impossible to teach Americans this moderately subtle point about macroeconomics, and (b) cynical politicians will relentlessly exploit Americans’ ignorance on the matter.

I recently heard a man on a call-in radio show ask an interview subject how he could explain to his son why we bailed out large banks that caused the crisis and left his sons generation to pay the bill. But as the diagram shows, there’s nothing to explain. The TARP is in no way a long-term drain on federal finances. (Indeed, odious as it may be to bail out rich, irresponsible bankers, the TARP almost certainly helped prevent a second Great Depression and a loss of output that would have significantly damaged the material prospects of all future generations.) The correct question would be: “Why did you feel it necessary, at a time of relative prosperity, to have a massive tax cut that our generation will have to pay for?” I suspect the question will never be asked since nothing suggests Americans will ever be better informed about the true sources of deficits.

Armageddon: The Aftermath

So what happens now? This:

Now

  • $250 rebate checks are sent to senior citizens who hit the “doughnut hole” in their prescription drug coverage in 2010. (Government to pay an increasing share of “doughnut hole” expenditures through 2020 when the gap will be filled.)
  • Small businesses are eligible for tax credits, up to 35 percent of premiums, for purchase of employees' health insurance.

In 90 Days (June 21st)

  • High-risk pools to insure Americans deemed “uninsurable” because of preexisting conditions are established. 
In 6 Months (September 23rd)
  • Insurers are prohibited from denying coverage to children based on preexisting conditions.
  • Insurers are prohibited from rescinding coverage.
  • Insurers are prohibited from setting life-time limits on benefits.
  • Children are eligible to remain on parents’ insurance plans until age 26.

In 9 Months (January 1st, 2011)

  • Insurers are required to spend 80 to 85 percent of premiums on medical care. (Currently they spend as little as 60 percent.)
  • Medicare patients are eligible for annual free preventive care services, such as cancer screening. (Currently these require copayments.)  

In 2011

  • Drug manufacturers start paying $16 billion, and health insurers $47 billion, in fees through 2019.
  • Cuts to Medicare Advantage, totalling $132 billion over ten years, start.
  • Restaurant chains with 20 or more outlets are required to post calorie information on menus and drive-through signs.

In 2013

  • Individuals earning over $200,000 and couples earning over $250,000 start paying higher Medicare taxes (rising 0.9 percent to 2.35 percent) and a new tax of 3.8 percent on unearned income (dividends, interest).
  • Medical device manufacturers start paying a 2.9 percent excise tax on sales.

In 2014

  • Health insurance exchanges—marketplaces where people without work-based coverage can buy insurance—become operational.
  • Most people are required to buy health insurance.
  • People with incomes up to 133 percent of poverty are eligible for Medicaid.
  • Subsidies to help lower- and middle-income Americans buy health coverage are introduced.
  • Insurers are prohibited from denying coverage to anyone based on preexisting conditions.
  • Insurers are prohibited from imposing annual limits on benefits. 

In 2018

  • A 40 percent excise tax on “Cadillac” insurance plans (plans costing over $10,200 for individuals or $27,500 for families) is introduced.
In 2019
  • 32 million currently uninsured Americans are insured. 
These are, needless to say, just a smattering of the highlights. (For a more comprehensive list, see here.)

There are, of course, costs associated with the benefits of health care reform (and I’ve noted a bunch of them). But the case that health care reform doesn’t, on balance, make us a better society—let alone create a “health care gulag” (John Cornyn) or “ruin our country” (John Boehner)—is hard to make.


March 20, 2010
The Hype  

In the American media tradition of hyping everything, even the New York Times and NPR almost never fail to call the health care reform “overhaul,” as if the reform will affect every aspect of the U.S. health care system. Melissa Block in one NPR interview used the term “total overhaul” twice to describe the reform. Even the informed Julie Rovner usually uses the word “overhaul.” 

The reality is that the vast bulk of the U.S. health care system will be unaffected by the reform. Health care delivery will be mostly untouched (and then only mildly and positively). Doctors, nurses, surgeons, pharmacists, receptionists, etc., will all perform their work exactly as before. Patients will generally see no change. (The more reflective among them may wonder what in the world all this hullabaloo was about.) Most of the insurance industry will be unaffected. If your coverage is through your employer or Medicare, you’ll probably see no change whatever in your health care.

The one corner of the industry that really will be affected is the individual insurance market. So those who buy their own insurance or are uninsured will notice the change. These groups comprise about a quarter of the population. 

Reporters are wont to imply the reform will rework “one-sixth” of the economy. Well, let’s see. The bill costs $940 billion over ten years. That’s $94 billion per year. Total health care spending in 2009 was $2.5 trillion (17.6 percent of GDP). So the bill will account for about 3.8 percent ($2.5 trillion ÷ $94 billion) or one-25th of total annual health care spending. And it will account for a little over half of one percent ($14.6 trillion ÷ $94 billion) or one two-hundredth of annual GDP. So should we call it a government takeover of one two-hundredth of the economy? And this is abstracting from economic growth, which will, of course, make the proportion smaller and smaller as the years go by.

The media evidently has an interest (and I’m somewhat surprised to have to include the relatively staid news organizations, the New York Times, the NewsHour, and NPR, in this) in making things seem more momentous than they are. The problem is that this has scared people needlessly and endangered passage of a badly needed, sensible reform. It’s played into the hands of right-wing manipulators, and helped foster the spectacle of people in streets, with placards of Obama with a Hitler moustache, protesting a conservative insurance market reform that most people won’t notice and most would actually like if they knew the details of it. The farcical nature of this is a bit beyond words.



March 19, 2010
How to Explain It

The fact that health care reform is controversial turns the economist’s assumption about the rationality of individuals on its head. To be earnestly against the Democrats’ health care reform plan one would have to believe one or more of the following:

  • “I hope they don’t close the Medicare ‘doughnut hole’.”
  • “I want to be unable to change jobs or move to another city because, if I did, I’d lose my employer-provided health care coverage.”
  • “I want to be denied coverage because of a preexisting condition.”
  • “It’s okay if my insurance is rescinded when I become seriously ill.”
  • “I want my insurance to have lifetime payment caps so that if I’m stricken with a serious illness I can choose bankruptcy or death.”

No human being in the world, who’s rational, holds any of these beliefs, of course. Which makes opposition to health care reform puzzling. In vain one waits to hear just one reasoned, informed rationale from a “grass-roots” protester, on radio or television, for their impassioned opposition to health care reform. At a recent speech by President Obama on health care, the crowd was mostly respectful. But one exception was a man so passionately opposed that he shouted repeatedly from the back of the venue. Interviewed on NPR¸ he said he opposed the bill (1) because it would provide federal funding for abortions (which it won’t) and (2) because it would increase the federal debt (which it won’t). (The reporter who interviewed him (Don Gonyea), needless to say, made no effort to correct him or the record.) And this is one of the more lucid explanations from a “grass-roots” activist for opposition to the bill. Usually they talk about “socialism” or a “government takeover of health care” or whatever.

The benefits of health care reform are immense, the costs negligible. The upside is obvious, the downside hard to see (or at least not articulable by anyone opposed to it). So why has health care reform been such a slog?

My analysis is this. Health care reform is somewhat complex (not extremely, but somewhat). Americans on average are of average intelligence. They’re busy, with little time or inclination to study matters of public policy. Their steady diet of junk information leaves them intellectually unprepared for issues of modest complexity, like health care reform. And within this informational void Republicans and right-wing commentators have free reign to lie and to lie and to lie. And they’ve taken full advantage. Here’s Dave Camp, Ranking Republican member of the House Ways and Means Committee:

“They [the American people] don’t want a trillion dollar bill. It’s going to take thousands of pages of legislation. It’ll raise taxes, increase the debt, and cause them to lose their health care… I think we ought to work on a bill that doesn’t cut Medicare, that doesn’t raise taxes, that doesn’t put more debt on the American people.”

There are two things going on here: spin—framing things in misleading ways—and overt lying. In the category of spin is the implication that the bill will raise your taxes. It would raise some peoples’ taxes—those of affluent Americans or workers with “Cadillac” insurance plans. But that’s a small portion of the population. And almost certainly it won’t raise “your” taxes.

Also in the spin category is the claim that the bill will “cut Medicare.” (Arguably this is closer to overt lying.) Yes, the bill seeks Medicare savings (1) by reducing overpayments to Medicare Advantage and (2) by establishing a Medicare commission—a panel of independent experts that would craft packages of delivery-system reforms to be voted up or down by Congress (with no amendments or filibusters, to free the reform process from special interest politics).

But the Medicare commission is essential if we are to deal with the long-term fiscal problems of the U.S. And the cuts in Medicare Advantage are fully justified. Medicare Advantage, as you may know, is a program whereby some Medicare funds, rather than being paid directly to health care providers, are funneled through private insurers. The idea was to get more bang for the buck, i.e., more medical care per dollar of spending, which would be possible because, as we all know, the private sector is much more efficient than the public sector in all things. The only problem is that it hasn’t worked. Through Medicare Advantage the government pays the private plans, on average, 14 percent more than the same services would cost under traditional Medicare. So taxpayers and other Medicare beneficiaries are in effect subsidizing the 10 million or so people on Medicare Advantage. And many of the latter receive supplemental benefits (like vision, dental, even gym membership) that traditional Medicare beneficiaries don’t get. So it’s unfair. Reducing these overpayments is good public policy.

In the overt lying category is the claim that the plan will cause people “to lose their health care.” In fact most people, covered through their employer, will see no change whatsoever in their health care. The bill will, however, extend health care coverage to 32 million people, according to the CBO. And math is hard, but I think 32 million is a positive number. 

Also in the overt lying category is the claim that the bill will “increase the debt.” How do Republicans get away with so baseless a claim? And why are so many Americans so gullible as to believe it? And why can’t the media set the record straight? Anyway, the CBO estimates that the legislation will reduce the deficit by $138 billion in the first ten years and by $1.2 trillion over the first 20 years. Not trivial. It’s the most serious effort to get the American fiscal house in order since 1994.

It’s astonishing how easy it is to wield the tool of lying in American politics. Apparently you just have to do it. You won’t be taken to task by the media. And you’ll have millions of easily-scared Americans at your feet. The only way to discourage use of this tool is for its use not to be rewarded. Passing health care reform won’t end the use of lying in American politics. But it will be a setback for the tactic. It could be a step (albeit a small one) forward in the evolution of a culture in which politicians are at least somewhat accountable to the truth.

Is Health Care Reform Popular?

Yes, it is. The American people favor the Democrats’ health care reform plan, substantively. They don’t know whats in it. And they don’t know that they like it. But they like it. So why does everyone think Americans oppose health care reform? Because when asked to say, up or down, whether they favor it, a plurality of Americans says it doesnt:


(But note the apparent narrowing of the gap in recent weeks.)

And how do we know Americans really favor the plan? Well, here are four pieces of evidence that make it plain:

1. Wall Street Journal/NBC Poll

In a series of Wall Street Journal/NBC polls conducted last year, Americans were asked the following question:

“Now I am going to tell you more about the health care plan that President Obama supports and please tell me whether you would favor or oppose it. The plan requires that health insurance companies cover people with pre-existing medical conditions. It also requires all but the smallest employers to provide health coverage for their employees, or pay a percentage of their payroll to help fund coverage for the uninsured. Families and individuals with lower- and middle-incomes would receive tax credits to help them afford insurance coverage. Some of the funding for this plan would come from raising taxes on wealthier Americans. Do you favor or oppose this plan?”

And here are the results:

 

So when people are told what’s in the plan—rather than asked to say, up or down, whether they favor something called “health care reform”—they like it. (For some reason the pollsters discontinued this question in subsequent versions of the poll.)

2. Kaiser Health Tracking Poll

In a Kaiser Family Foundation survey of January of this year, the legislation was divided into 27 features, most of them components of the bill, some not, but all in the discussion about health care. In view of the fact that “many Americans remain unaware of the specific content of the legislation,” a “subset of Americans were told the proposed legislation included each provision and asked whether that particular element made them more likely to support health reform, less likely to support it or didn’t affect their views.” Here are the results (which I’ve re-graphed for ease of comprehension):

 

Note well: The red lines are longer than the blue ones in 22 of 27 cases. And the exceptions are unsurprising:

*Basic benefits package, defined by the government: Smacks of an enlarged government role, which has negative connotations for Americans conditioned by decades of demonization of government (some of it deserved, much of it part of a cynical “starve the beast” strategy). But of course a government-defined benefits package is an essential consumer protection. Every state has one. Many women, for example, will be thankful to discover that their insurance plan was required to cover breast cancer care.

*Cadillac-plan tax on insurers: Anything with the word “tax” in it (unless followed by the word “cut”) is unlikely to poll well. (Still the Cadillac-plan tax is a good idea that sadly has been watered down.)

*Not take full effect until 2013: But the only reason this would be a negative is that the bill is viewed favorably overall.

*Individual mandate/penalty: No doubt requiring people to buy insurance (or anything) feels like (a) an infringement on liberty and (b) a potential source of economic hardship. But the question is meaningless unless conjoined with two other questions: the question about guaranteed issue, since we can’t have guaranteed issue without the individual mandate, and the question about subsidies, since the point of the subsidies is to make the mandate workable. Putting these three components together, we have:

My guess is that Americans would accept the mandate as part of a package that includes guaranteed issue and subsidies that help people pay their premiums. (See the question about the mandate and subsidies in the Newsweek poll results below.)

*Cost at least $871 billion over 10 years: An abstract question about the cost of anything not explicitly tied a benefit will always poll badly.

3. Newsweek Poll

Very similar results were found in a recent Newsweek poll (PDF of topline results here). As Newsweek notes, “The majority of Americans are opposed to President Obama's health-care reform plan—until they learn the details.”

The pollsters first asked respondents whether they favored or opposed the bill. They found that 40 percent favored it and 49 percent were opposed. They then asked the respondents whether they favored or opposed eight specific proposals that are in the plan. Here are the results:

(Note: The red lines are longer than the blue ones in all but two cases.)

Finally, the pollsters asked: “Now please think about the proposals I just described to you. ALL of these proposals are included in Barack Obama’s health care reform plan. Having heard these details, what is your OVERALL opinion of Obama’s plan – do you favor it or oppose it?”

The results: 48 percent in favor; 43 percent opposed. And remember, this swing occurred among respondents who had answered the same question just minutes before.

4. Popularity of the Massachusetts Health Care Reform

Then there is the Massachusetts health care reform plan, nearly identical to the national one proposed by the Democrats, and generally popular. A poll by the Harvard School of Public Health and The Boston Globe, for example, found that Massachusetts residents favor the plan by 59 to 22 percent and that 79 percent want the law to continue while just 11 percent want it repealed. Support is even stronger among physicians. A New England Journal of Medicine poll found that physicians favor the plan by 70 to 13 percent and that 75 percent say the law should continue while just 7 percent want it repealed.

In Sum

The plan is obviously a political winner. And the Democrats will get credit for it for years to come (as with FDR and social security and LBJ with Medicare). The Republicans know this and so must demonize it and kill it if at all possible. Before the bill passes, before the public knows much of anything about it, this is still possible. After the bill passes, I trust the Democrats will never let Americans forget who pulled out all the stops to try to kill it.

The Point of the Public Plan


In a recent New York Times/CBS poll about health care reform, the dominant note was confusion. Asked, “Do you think you understand the health care reforms under consideration in Congress, or are they confusing to you,” 59 percent answered “confusing.” Asked, “Do you mostly support or mostly oppose the changes to the health care system proposed by Barack Obama, or don’t you know enough about them yet to say,” 47 percent said “don’t know enough” (30 percent said “mostly support” and 23 percent said “mostly oppose”).

But perhaps the most striking finding was the response to this question: “Would you favor or oppose the government offering everyone a government administered health insurance plan — something like the Medicare coverage that people 65 and older get — that would compete with private health insurance plans?” (tracked over five polls):



(The title of the online version of the article is “Poll: Support for Government Health Insurance Declines a Bit.” Hmm.)

Evidently all the badmouthing in the world hasn’t shaken peoples’ support for the public option, at least if it’s defined as a “Medicare”-like program for people under age 65. People know few details about the health care debate, but they know what they like. And they like Medicare, and thus also, presumably, the idea of extending “Medicare”-like coverage to everyone.

Still the poll reveals astonishing confusion about health care reform, rendering almost meaningless much of the chatter of pundits about what people believe. One of the only consistent patterns is that when polling questions explain the details of the proposed legislation a bit, as in this question, people are generally more supportive than when they’re given the language of the actual debate.

In another recent survey, just 37 percent of respondents correctly matched the term “public option” to its definition among four choices (one of which was “don’t know”). Had the respondents merely guessed and scored at chance level, they could not have done much worse. Evidently but a fraction of the American people know what the public plan—the most contentious aspect of the proposed health care reform—is.

So what is the public option? It would be a government-run insurance plan, available to people without employment-based coverage, purchased through an insurance “exchange” on which it competes with private insurance plans. There are different versions of the plan, of varying degrees of “robustness.” The most “robust” of these would (a) be able to use its purchasing power to restrain medical costs and (b) be national in scope so that coverage would be available on common terms throughout the country. Weaker versions of the plan lack one or both of these features. Respondents in the New York Times/CBS poll clearly had in mind a fairly “robust” version of the plan.

The Idea Behind the Public Plan

The purpose of the public plan, as stated by its progenitor Jacob Hacker of Yale, is (a) to “spearhead” the development of new payment and quality-improvement methods, (b) to help control costs, and (c) to provide a standard or benchmark against which private plans can be assessed. Let’s take these points in turn:

(a) As a Vehicle to Test and Evalutate Delivery and Payment System Reforms

In our fragmented, unstable insurance market, individual insurers have little incentive to undertake payment and quality-improvement initiatives that might pay off in the long run. A public plan, argues Hacker, with a stable enrollment base, would be poised to undertake such initiatives. These might include:
  • Improving the use of information technology.
  • Developing methods of linking payment to performance as an alternative to fee-for-service.
  • Conducting large-scale comparative-effectiveness research with results shared rather than kept proprietary.
  • Developing improved modes of care coordination.
  • Shifting payment methods and rates to better reward primary care practitioners.
Thus the public plan, like Medicare and the Veterans Health Administration, could provide a testing ground for large-scale innovations. Many economists, however, argue that governments are poor innovators. Richard Thaler, for example, argues that a public plan wouldn’t compete well with private insurers because “governments are not very good at innovation,” and he quotes the great 19th-century economist Alfred Marshall: “A government could print a good edition of Shakespeare’s works, but it could not get them written.”

This may be true in many areas. But health care seems not to be one of them. In particular, democratic governments, when seen as responsible for their health care systems, are under constant popular pressure to improve the quality of care and the efficiency of their payment systems, and they respond positively. Indeed most industrialized countries’ health care systems are in a more or less permanent state of reform, with countries like France, Germany, and Great Britain significantly reforming their health care systems every several years (See T.R. Reid). (Here, of course, it’s once-a-generation thing.)

France has its carte vitale, a credit card-like piece of plastic that people carry and that contains their complete encrypted medical histories. The health care provider places it in a desktop machine, records any new medical information, then with a keystroke transmits all billing information to all relevant insurers. Germany now has its smart card, modeled after the carte vitale. In terms of payment efficiency, some of the other OECD countries are ten steps ahead of us, and it’s because of, not in spite of, their governments’ role in health care.

A vehicle for testing and evaluation of delivery- and payment-system reforms would be a good use of a public plan.

(b) As an Instrument of Cost Control

A public plan could help control costs in three ways:
  1. Since a public plan would have no underwriting or marketing costs, and wouldn’t pay profits to shareholders, it would have lower administrative costs than private insurers.
  2. By offering lower-priced coverage, it could compel private insurers to innovate in ways that lower their own costs, enabling them to charge lower premiums.
  3. With a large enrollment base, a public plan could use its market power to restrain the prices it pays for medical care.
Reasons (1) and (2) are reasons why the public plan might have a modest effect in controlling costs. But the main way it could affect costs is (3) by using its market power to negotiate prices with providers. Unfortunately it’s unlikely to have much effect here given the enrollment rules stated in the congressional bills that contain the public plan. For example, the tri-committee House bill, the most liberal of the bills under consideration, restricts enrollment to unemployed or self-employed individuals and to businesses with 50 or fewer employees. That leaves out the bulk of the population. The CBO estimates that with these restrictions enrollment in the public plan would be just 9-10 million people when the plan is fully implemented. So even if the public plan were allowed to negotiate prices, it probably couldn’t exert much financial pressure on providers.

However, the economics of cost control are complex. A major reason for our runaway health care costs is a fragmented demand side, i.e., the fact that there are so many purchasers of health care that most have little power to negotiate prices. Adding in another buyer (particularly if the exchanges are statewide rather than national, as in the Senate bills, and if enrollment is as small as the CBO projects it will be) in the form of a public plan could fragment the demand side still more, causing higher, not lower, prices. So it’s not altogether clear what the public plan’s effect on medical prices would be.

Insurance premiums, however, may be a different matter. A recent AMA survey found that of 314 metropolitan markets 94 percent were controlled by one or two insurers and that in 15 states one insurer had at least 50 percent of the market. Given the near-monopoly of insurers in many markets, the public plan could be a necessary complement of mandates, since if everyone is obligated to buy insurance, that would increase insurers’ market power still more and premiums may skyrocket. Given the for-profit nature of U.S. health insurance—a status the proposed reform would do nothing to change—a public option to counteract this enhanced market power may prove a public policy necessity.

But there are many moving parts in the proposed legislation. The three House bills and the Senatate Health, Education, Labor and Pensions (HELP) committee bill contain “prudent purchaser” clauses that, as in Massachusetts, empower staffs of the proposed exchanges to bargain over premiums and set standards plans must meet in order to offer insurance through the exchanges. (The House bills propose a nation-wide exchange; the Senate HELP committee bill proposes state-wide ones.) In other words, the exchanges in these bills utilize their broad risk pools to influence premiums (as in Massachusetts where premiums for plans on the exchange have actually fallen by 6 percent this year) and ensure a critical minimum level of quality. 

But the Senate Finance committee bill inexplicably lacks this provision. An amendment by John Kerry to add it was reportedly blocked by Olympia Snowe who argued that such oversight would be “too much government” (see Jonathan Cohn). But if such a provision isn’t in the final bill, there could be a serious problem of rising premiums absent a public plan.

(c) As a Standard or Benchmark for Assessment of Private Plans

When stating the purpose of the public plan, politicians and commentators routinely say it’s to keep the insurance companies “honest.” What does this mean? The envisioned reform would prohibit insurance companies from denying coverage on the basis of pre-existing conditions, end rescission, end annual and lifetime payment caps, limit policyholders’ out-of-pocket expenses, guarantee renewability, etc. Won’t the insurance companies be legally obliged to keep “honest”?

The problem is that under the proposed reform health insurance companies will still be for-profit entities. Which means revenues they receive above cost will still be profit to be distributed to shareholders. Which means these companies will still be under pressure to cut costs however possible. Which means incentives to deny claims or avoid insuring high-risk individuals won’t go away. Which means insurers will have incentives to try to get around the regulations.

Thus even if reform is enacted, Hacker argues, private insurers will have incentives to tailor “their benefits or provider networks to discourage less healthy people from enrolling.” For example, they might market disproportionately to the young. The public plan, he says, “creates an institutional ‘check and balance’, encouraging private plans to uphold high standards of quality, affordability, and access.”

The Point of the Public Plan

Hacker’s vision of a “hybrid” system in which private for-profit insurance companies compete side-by-side with a public plan may work beautifully, but it’s untried. All other countries that combine a mandate and regulations to achieve universal coverage don’t have a “public option” and nearly all finance basic health care through not-for-profit insurers. That means that revenues above cost aren’t distributed to shareholders but are funneled back into the activities of the companies (e.g., to lower policyholders’ premiums in the following year, as in Switzerland), and firms compete on quality of product rather than by cherrypicking the healthy and denying claims.

The core issue that reform needs to address is an inherent contradiction between the product people want and the product an unregulated for-profit individual insurance market can provide. Cost-cutting to enhance shareholder value means denying claims when possible and avoiding covering high-risk individuals—features incompatible with the product people want, which is a secure financial guarantee of access to health care so that when they face life-and-death medical situations they’ll neither die because care was denied them nor go broke (or watch their family go broke) paying for it. It’s a product that a rich society can provide, as seen in most other OECD countries. But to get it we need to get around our for-profit insurance industry, since we’re clearly not willing to sacrifice it. The point of the public plan, from a public policy perspective, is to get around this handicap.

The point of the public plan, in the public mind, is rather different, judging from the polls: it’s to provide once and for all the product our current system so woefully lacks—secure access to health care throughout life. But this robust version of the plan—the version that polls so well—isn’t what’s on the table. As proposed in the bills passed out of the relevant congressional committees, the public option won’t be an option for very many people.

Outcome Uncertain

No one knows exactly what will happen if a public plan is enacted. There’s a question of whether the envisioned “hybrid” system would be stable or would evolve toward something different, like a single-payer system, as conservatives fear. People often cite the coexistence of the post office and for-profit parcel delivery services like UPS and Fedex as proof that a government enterprise, even a taxpayer-funded one, won’t necessarily run private sector firms out of business. But the postal example actually illustrates something else: that a government-run enterprise and private sector firms tend to offer different products. In the case of postal service, the post office handles the basic product, routine mail delivery. This might be analogous to the public plan which would offer a standardized insurance product sufficient for everyone’s basic needs, including secure knowledge that one won’t die for lack of care or go bankrupt paying for it. The for-profit parcel carriers, on the other hand, handle supplementary products like overnight delivery. This might be analogous to for-profit insurers that provide supplementary health insurance like coverage for private hospital rooms, private nursing, dentistry, non-traditional medicine, etc., as is offered in many other countries. So I suspect that if a public plan competes against private insurers the market would segment. For basic health care coverage, people will be attracted to the transparency and stability of a government-run plan. For frills not available through the public plan they’ll turn to for-profit insurers.

The narrow enrollment rules in the House bills and the Senate HELP committee bill seem designed to prevent the system from evolving toward a single-payer system. Still it’s possible that in the very long run our system of employer-provided insurance will completely collapse, in which case the public plan would be there as an option. Should everyone choose it, we would have, de facto, a single-payer system.

On the other hand, the public plan could fizzle. It’s possible, as Paul Starr argues, that unless the exchanges have effective risk-sharing mechansims, so that all incentives for insurers to cherrypick are gone, the public plan could become a repository for more expensive, high-risk individuals. Its financing would then skyrocket, its political support would ebb, and the health care system would probably be made worse. The public plan would provide a place for insurers to offload high-risk cases, while opening to insurers a field of less expensive, low-risk individuals now mandated to buy insurance.

Is the Public Plan Necessary?

In a July 30th letter, 57 members of the House threatened to oppose a health care reform bill if it doesn’t include a robust public option. If they’re serious, with these numbers they could kill health care reform.

The thing is, the public option is not a pillar of reform, such that if removed the entire edifice of reform would collapse. At best it’s a very good idea. The pillars of reform are (see Paul Krugman):
  • Regulations, so that everyone is covered without regard to preexisting conditions and claims can’t be denied, etc.
  • Mandates, so that regulations are economically viable for insurers.
  • Subsidies, so that mandates are economically viable for low-income individuals and small businesses.
  • Competition, so that the insurance market produces a product of a price and quality that people want.
If any of these four components were removed, the edifice really would collapse. If mandates weren’t in the bill, as some Republicans would like, the regulations would be unviable for insurers. If subsidies were inadequate or nonexistent, the mandates would be unenforceable. If regulations weren’t sufficiently stringent, perverse incentives of insurers to cherry-pick the healthy and deny claims would remain. And if a new arena of competition weren’t established in which insurers compete on quality and price rather than by maximizing shareholder value, the needed insurance product wouldn’t materialize. In all these scenarios reform would collapse.

The public plan is an aspect of one of these components, competition, but not its major aspect. The major aspect is the exchanges. And theoretically, depending on a host of factors not fully worked out, the exchanges could provide the type of insurance product we need.

It now appears that a compromise involving either opt-in or opt-out rights for individual states might be struck. Such a compromise might be desirable, not just becuase it mends political fences but because it would create an experiment in which we could see what actually happens when a public option exists.

The Senate Finance committee bill (the Baucus bill) is problematic. But it’s not the final bill. It will be blended with the Senate HELP committee bill and then with a House bill. And the resulting final bill will almost certainly be vastly better than the status quo.

Yes, the ideal may be to provision basic health care coverage through not-for-profit means—by government or by not-for-profit insurers. But given our peculiar political contraints, the achievement would be impressive nonetheless. The final bill will:
  • End denial of coverage because of preexisting conditions.
  • End rescission.
  • Limit annual and lifetime out-of-pocket expenses.
  • Require automatic renewability.
  • End lifetime payment caps.
  • Expand coverage to nearly everyone.
It would eliminate the most barbaric aspects of our health care system. To kill it merely because it lacks a public plan (of uncertain effect) would be unforgivible.

The Context of Health Care Reform


Frustrating listening to tonight’s NPR report about health care reform. In the report Dave Koenig, an upper middle-class businessman in a suburb of Sacramento who’s satisfied with his employer-provided group coverage, was interviewed. He says he wouldn’t mind “reform” that would prohibit denial of claims based on “preexisting conditions” and end rescission, etc., but he doesn’t want “massive overhaul.” “I can see reform taking place in areas,” he says, “but do I want the system overhauled? No. And I don’t think the majority of the people in the country want it overhauled.”

He’s right. A majority of the country doesn’t want the system “overhauled.” Which is fortunate, since under the Obama reform plan the system will not be “overhauled”—at least not by any reasonable definition of the term.

Happily, Karen Politz of Georgetown University noted that Koenig has nothing to fear from the contemplated reforms. As long as Koenig’s policy meets certain quality standards (which it clearly does, based on Koenig’s description) nothing would change for him under the new law.

(And of course policymakers have consistently emphasized that if you have employer-provided insurance and like it, you can keep it. If this piece of information hasn’t yet sunk in, it obviously never will. Normally in politics, if you say something enough times, even if it’s nonsense, people will begin to believe it after a while. In this case it’s the opposite. No matter how many times Obama and others say it, even if it’s true, few evidently will ever believe it. It’s apparently just scare words, not comforting words, that people believe when they’re said again and again.)

But Melissa Block, interviewing Politz, repeatedly used the term “total overhaul” to describe Obama’s health care reform plan. This terminology—common in reporting about the issue—is scaring people needlessly. If “total overhaul” is what Obama wants, what exactly do single-payer advocates want? For that matter, what did John McCain want? He proposed taxing employer-provided health insurance as income, which would have quickly ended employer-provided insurance like Koenig’s. That was of course the idea—to end employer-provided insurance and shepherd everyone into the glorious free market for individual insurance, the market that has spawned nearly all the horror stories we’ve heard lately about denials of coverage, rescissions, etc.

I suspect Koenig, a “conservative” as described in the report, wasn’t too scared to vote for McCain, although admittedly the news media almost certainly didn’t tell him that he thereby voted to end his wonderful insurance arrangement.

The key contextual fact about health care reform is this:





A decline in employer-provided coverage from 63.9 to 58.5 percent (top diagram) over nine years may not look dramatic. But the process is inexorable: as health care prices rise, insurance will become increasingly unaffordable to companies, and employer-provided coverage will erode.

Where will people go as employer-provided insurance erodes? None of the current options—the individual insurance market, some form of government coverage, or no insurance at all—are desirable or sustainable in the long run. At present the bulk of people are turning to the government or going without insurance. But as the federal government cuts budgets, the individual insurance market may become the primary destination for people cut loose from employer-provided plans, truly a health care catastrophe.

Among available reform options, Obama’s proposal is the most conservative response on offer. As employer-provided insurance erodes, the idea is to let people stay in it as long as they wish or can, and then if they lose this coverage (as people increasingly will) the reform will provide a place for them to go. Right now, for example, if Koenig loses his job or changes it, he will lose his beloved insurance and may well be thrust into the individual insurance market. Under the Obama plan, if he loses his job or changes it, he will be able to purchase group-like insurance—either a private plan through an insurance exchange or the public option (should that become available). That’s what the reform means to people like Koenig: that rather than being dumped into the individual insurance market or forced to go uninsured or join the rolls of Medicaid, they’ll have an option that preserves the quality of coverage to which they’ve become accustomed. And that’s what Politz should have said.


September 27, 2009
Addendum


Regarding John Tierney’s Times piece on the work of Samuel Preston and Patricia Ho, several points:

1. There’s confusion about the meaning of the word “system” in “health care system.” Preston and Ho seem clear that a “health care system” comprises many things, some related to quality of care, others to access to care. But their analysis is confined solely to issues of quality of care—specifically “screening for cancer, survival rates from cancer, survival rates after heart attacks and strokes, and medication of individuals with high levels of blood pressure or cholesterol” among people over age 50. Since health care systems address the health needs of all people suffering from all conditions, and encompass issues of access and prevention as well as care, Preston and Ho’s findings are not an answer to their question, “Does a poor performance by the US health care system account for the low international ranking of longevity in the US?” (italics added) Thus the title and stated purpose of their work is misleading.

On the other hand, “amenable mortality”—deaths of people under age 75 from “treatable” conditions—is a metric that theoretically could be used to compare different countries’ health care systems. One could quarrel with any specific definition of “amenable mortality”—specifically, what conditions should be counted as “treatable”—as Preston and Ho do with that of Nolte and McKee. But a measure that only looks at detection and treatment of conditions wherein the U.S. is known to specialize, and then only when they afflict people 50 and older, is hardly a substitute for a concept that considers all “treatable” conditions afflicting people 75 and younger. And Preston and Ho don’t really argue against the concept of amenable mortality, but mainly against its specific instantiation in the work of Nolte and McKee. Which is fine, but a reasonable response would be to propose a redefinition of the term, not a wholesale abandonment of the concept.

2. The one possible justification for abandonment of “amenable mortality” is a view Preston, Ho and Tierney endorse: that lower life expectancy of Americans is primarily caused by higher disease prevalence in the U.S., i.e., that Americans for some reason are “sicker” than the peoples of other countries. If true this would undermine the use of mortality statistics to assess a country’s health care system since high mortality could then result from factors outside the health care system.

Tierney writes: “Americans are more ethnically diverse. They eat different food. They are fatter. Perhaps most important, they used to be exceptionally heavy smokers.” Fatter, yes. But aren’t Europeans (especially when combined with the Japanese and Australians, as is typically done in these comparative studies) also ethnically diverse? Aren’t their diets, ranging from Greek to Spanish to Italian to German to French to English to Scandinavian (and Japanese), at least as diverse as American diets?

But as to whether Americans are sicker than people in other countries, that doesn’t appear to be the case. As noted in my previous post, a 2008 study by the McKinsey Global Institute found that “of 122 diseases within 35 medical conditions representing 37 percent of total US health care spending—including heart conditions, trauma, cancer, mental disorders, and diabetes—the United States has a lower prevalence of disease than France, Germany, Italy, Spain, and the United Kingdom” (italics added).

As for smoking, it’s true that Americans were once heavy smokers (though now we’re among the lightest smokers in the industrialized world). But going back to the McKinsey report, the authors observe (explaining their finding that Americans have a lower disease prevalence than the citizens of other industrialized countries) that “smoking figures in the United States are far lower than in the comparison countries [France, Germany, Italy, Spain, and the United Kingdom]” and that the U.S. has “a third fewer” cases of chronic obstructive pulmonary disease than the comparison countries. A “third fewer”? Clearly some empirical investigation is in order. Finally, the report notes (further explaining its finding that the U.S. has a lower disease prevalence than other industrialized countries), “the United States benefits from a younger population with an overall lower prevalence of conditions associated with age, such as heart disease, even though incidence rates may actually be higher for some segments of the population.”

In any case, if our higher mortality rates really were a legacy of our heavy smoking past, why would Americans’ mortality after age 65 (presumably the cohort of the heaviest smokers or former smokers) be approximately the same as that of other countries? Also, most smoking-related deaths occur after age 65. (One well-known study found that a life-time of smoking reduces life expectancy by ten years. For a summary, see this.) So why should our smoking legacy affect younger age cohorts so adversely?

3. Of the relatively high mortality rates of younger and middle-aged Americans, Tierney writes: “Many of those deaths have been attributed to the health care system, an especially convenient target for those who favor a European alternative.” Since in Tierney’s view many of these deaths are not attributable to our health care system, our high mortality numbers would not be evidence that we should adopt a European-style model (i.e., one of those models that provide approximately equivalent care to ours at about half the cost and cover nearly everyone).

It’s not clear that Preston and Ho have the same take on their findings. As noted, they seem to recognize that health care systems comprise not just detection and treatment of a small range of conditions, but prevention of illness broadly. They write:

Medical procedures and survival rates are indicators of what happens to individuals whose health problems come to the attention of the health care system. But a health care system can also help prevent serious health problems from occurring in the first place. Of course, early identification of a disease is also preventative medicine in the sense that it may prevent death. But access to preventive medicine would appear to be an especially problematic area in the United States because 47 million people lack any form of health insurance.  Such people are less likely to see a doctor and thus to receive routine testing that might detect the early stages of a disease and prevent its clinical manifestations (Institute of Medicine 2001). They are also less likely to receive advice about health maintenance and disease prevention.

This would seem like an endorsement of the insurance market reform currently being contemplated by Congress, reform that would move our system closer to that of Germany, the Netherlands, and Switzerland. (Which doesn’t explain the title and stated purpose of their paper.) But Tierney’s take seems to exhibit a reflexive conservative impulse to defend the status quo no matter what.

Of course it’s not the quality of care, but access to care wherein the “European” models are superior. As T.R. Reid says in his excellent new book (a must-read for anyone interested in the issue), “the United States does well when it comes to provding medical care, but has a rotten system for financing that care” (p. 225). And it’s access to care that plausibly accounts for our high mortality numbers.

One comprehensive study of the relationship between access to care and health outcomes is this one by the Institute of Medicine. Among its findings:

  • Uninsured cancer patients…are more likely to die prematurely than persons with insurance, largely because of delayed diagnosis.
  • For five disease conditions (diabetes, cardiovascular disease, end-stage renal disease, HIV infection, and mental illness), uninsured patients have consistently worse clinical outcomes than insured patients.
  • Uninsured adults with hypertension or high blood cholesterol have diminished access to care, are less likely to be screened, are less likely to take prescription medication if diagnosed, and experience worse health outcomes.
  • Uninsured adults with HIV infection are less likely to receive highly effective medications…and die sooner than those with coverage.
The report also references a “statewide study of uninsured auto accident victims” that found that uninsured patients “had a 37 percent higher mortality rate than did privately insured accident victims.”

Rocket science it isn’t. Many Americans lack secure access to health care, so Americans on average die younger than people in other advanced industrialized countries. (And if you need to put a name and story to the numbers, read the harrowing tale of Nikki White in Reid’s book (pp. 209-12).)

That excellent minds should spend time and resources trying to torpedo the obvious is sad.

Is Low Life Expectancy the Fault of Our Health Care System?


A recent working paper by University of Pennsylvania demographers Samuel H. Preston and Jessica Y. Ho considers whether Americans’ low life expectancy, compared to that of other advanced industrialized countries, is the fault of the U.S. health care system. Their answer, based on the health outcomes of people over 50 suffering from such conditions as heart disease, stroke, and cancer, is no.

The problem with the study is its narrowness. It focuses on a narrow class of emergency conditions afflicting one class of patient, the elderly. And of course we know that U.S. health care caters well to this group, particularly with respect to the serious medical conditions considered in the study. So as an answer to the question posed, the paper is wanting.

If Preston and Ho’s measure of health outcomes of people over 50 with emergency medical conditions were, as they claim, a fair measure of the quality of our health care system, then logically the concept of “amenable mortality”—deaths before age 75 from conditions considered amenable to treatment by medical care—couldn’t be. And accordingly Preston and Ho criticize this metric (at least as formulated by Nolte and McKee), on two grounds:

(1) That it’s biased against the U.S. since it underplays or doesn’t include certain conditions (ischemic heart disease and prostate cancer) wherein U.S. care is distinguished.

(2) That the rate of decline in mortality among American males from “non-amenable” causes has been twice that from “amenable” causes, an anomaly that suggests “either flaws in the index or the unimportance of medical care relative to other factors that are operating.”

Two points:
 
(1) Supposing Preston and Ho’s objections to “amenable mortality” are fair, a reasonable response would be to redefine the concept to take account of these objections. We could then see how the U.S. compares with other countries in terms of the reformulated metric. Wholesale abandonment of the concept in exchange for measures in which the U.S. is known to excel is like throwing the baby out with the bath water.

(2) As to whether the U.S. has a high disease prevalence owing to factors outside the health care system, that doesn’t appear to be the case. A 2008 McKinsey Global Institute study, for example, found that “of 122 diseases within 35 medical conditions representing 37 percent of total US health care spending—including heart conditions, trauma, cancer, mental disorders, and diabetes—the United States has a lower prevalence of disease than France, Germany, Italy, Spain, and the United Kingdom” (italics added).

Thus I conclude that the mortality numbers are exactly what many health care reform advocates claim they are—an indictment of the U.S. health care system.

But what’s most peculiar is the pattern of mortality in the U.S. For both sexes and at every age level until late in life, the U.S. stands apart from every other advanced industrialized country. (The U.S. is represented by the thick red lines.)





(Data from W.H.O.)

Although these diagrams use raw mortality numbers (not “amenable” or any other specific definition of mortality), they clarify why Preston and Ho get results so different from analyses in terms of amenable mortality. If you consider mortality from age 50 onward and include mainly conditions in which the U.S. specializes, as Preston and Ho do, obviously you’ll get a very different picture from the one you’ll get if you consider mortality under age 75 and include all “treatable” conditions.

Why the peculiar pattern of mortality in the U.S.?

A recent Urban Institute review article, discussed in a previous posting, finds that U.S. health care overall is a “mixed bag,” with both strengths and weaknesses. Since the overall quality of U.S. care appears to be neither exceptional nor terrible, whatever association may exist between low life expectancy and our health care system is almost certainly an access issue rather than a care issue.

Resources not being infinite, health care, like any good or service, must be rationed. The question is how (by decision or by market) and what to ration, or more precisely, what not to ration. All other industrialized countries have decided that, given the existence of care that can effectively address serious medical conditions, no one—rich or poor—will be denied this care. In other words, no one will die or go bankrupt because a medical treatment available to the society is not made available to them. That’s a moral decision, one that I suspect most Americans would endorse.

U.S. policymakers, however, haven’t made that decision (although they appear to be on the verge of making it now), leaving us our de facto brand of rationing, i.e., by  price.

We see it in our out-of-pocket medical expenses:*


Broadly there two kinds of rationing: by price (or market) and by decision. The left-hand column below depicts rationing by price, i.e., percentages of repondents that have, over the previous year, foregone attention or treatment because of cost. In this category the U.S. is without peer. The right-hand column depicts rationing by waiting (a proxy for rationing by decision), wherein the U.S. typically, but not always, fares reasonably well.

Rationing by Price Rationing by Waiting

How might the different brands of rationing affect life expectancy? In no country with rationing by decision is there a waiting line for emergency care. Which is to say people get their foot in the door, have their medical conditions assessed, and rationing proceeds accordingly. Under a system of rationing by price, by contrast, rationing can occur at any point, including in the initial assessment phase. Unsurprising are the results.

The bottom line is that many Americans lack a product that the citizens of all other advanced industrialized countries have by right: a financial guarantee of access to health care during their working lives. It’s a product that Americans would almost certainly buy were it available, but not one that an unregulated or lightly regulated insurance market (owing to information asymmetries and adverse selection, to be discussed in future postings) can provide. It’s a product that requires a government guarantee.

These and the following data are from The Commonwealth Fund 2005 International Health Policy Survey of Sicker Adults in Six Countries, released in November 2005. The numbers refer to percentages of respondents. A more complete account would require data from other sources and years. Still a clear and unsurprising picture emerges. Note that these results arent cherry-picked. The three categories of rationing by price are the only categories of rationing by price in the survey. The four categories of rationing by waiting are the only categories of rationing by waiting in the survey.

What Americans Believe


David Brooks repeatedly tells us in his column and television and radio commentary that the public is “leaning against [health care] reform, at least as currently envisioned by the White House and the Congressional leadership.” Of course he’s just following the polls, which may seem to bear him out::


(Data and chart: Pollster.com. Each dot represents a poll conducted by a reputable polling organization between late April, on the left, and early September, on the right. If one takes this very literally one could argue that there’s been an upturn in support for the Democratic reform proposals since early August.)

But there’s a problem with these polls: almost no one surveyed knows what’s in the proposed legislation. And the major media aren’t wasting much time telling them. The “plan” that people increasingly oppose would, in the minds of many respondents in a Wall Street Journal/NBC poll, “give health insurance coverage to illegal immigrants” (55%), “lead to a government takeover of the health care system” (54%), “use taxpayer funds to pay for women to have abortions” (50%), and “allow the government to make decisions about when to stop providing medical care to the elderly” (45%). Indeed more people believe each of these things than oppose the plan itself (42%). 

So let’s pause to consider what constitutes genuine belief. Belief, ideally, should be based on knowledge. So, is genuine belief opinion held now but not, perhaps, three weeks from now when “facts” change? Or is it opinion held over months or years under stable conditions of knowledge? David Brooks’s answer is apparently the former. A rational answer is the latter.

Suppose the pollsters’ question about health care reform were reformulated by anchoring it to a bit of knowledge, as was in fact done in the Wall Street Journal/NBC poll:

“Now I am going to tell you more about the health care plan that President Obama supports and please tell me whether you would favor or oppose it. The plan requires that health insurance companies cover people with pre-existing medical conditions. It also requires all but the smallest employers to provide health coverage for their employees, or pay a percentage of their payroll to help fund coverage for the uninsured. Families and individuals with lower- and middle-incomes would receive tax credits to help them afford insurance coverage. Some of the funding for this plan would come from raising taxes on wealthier Americans. Do you favor or oppose this plan?”

Here are the results:



Evidently a stable majority of Americans supports the plan when they have some knowledge about it. These results suggest that support would stabilize at above 50 percent if people were ever to become better informed.

When there’s so large a discrepancy between informed and uninformed belief, surely that tells us there’s something seriously wrong with the information people have to help them form their opinions—which tells us there’s something seriously wrong with the major media, the main source of information people have about the proposed legislation.

Let’s examine another genuine—i.e., stable—belief:



(Data: Gallup)

There appears to be a dip in 2008, but I wouldn’t make too much of it. Belief in a governmental role in ensuring that people have health care coverage seems relatively stable. Thus we can, I think, infer that Americans regard health care as a right, as something the government has a responsibility to guarantee.

Long-term stabilities of belief are revealing, but so are long-term trends. In the last decade two issues, access to health care and health care/insurance costs, have emerged as by far the biggest concerns Americans have about health care. More than half of respondents in Gallup polls now cite one or the other as their top concern:



And of course access to health care and health care/insurance costs are the primary issues health care reform is designed to address.

Why these long-term trends? I suspect the cause is other long-term trends, like this one:



I was aware of our own special brand of health care rationing—price—but I hardly expected these numbers. Around 30 percent of households in each of the last three years say they’ve put off medical treatment because of cost.

Knowledge solidifies over time, perhaps through reasoning, perhaps through experience, but not through listening to talking heads whom most people don’t trust anyway. And mainly what Americans have had on the issue of health care reform thus far are talking heads. So I wouldn’t expect poll results that record fickle opinions of the moment to reflect genuine belief.

Brooks has a different take. Writes Brooks:

This is a country that has always been suspicious of centralized government. This is a country that has just lived through an economic trauma caused by excessive spending and debt.[*] Most Americans still admire Obama and want him to succeed. But if he doesn’t proceed in a manner consistent with the spirit of the nation and the times, voters will find a way to stop him.

For Brooks, fickle opinions of the moment are more than just expressions of genuine belief; they reflect transcendent truths about the American “spirit.”

But all dross aside, historically speaking the times are ripe for health care reform.

*This second sentence might seem a non sequitur. The crisis was caused by
“excessive spending and debt,” yes, but not excessive government spending and debt. The crisis had nothing to do with “centralized government,” but with the opposite, deregulation. Even granting Brooks’s conservative mindset, its hard to see what’s going on in his mind here.

American Health Care: 
Best in the World?

One obstacle to health care reform is the widespread perception that the quality of American health care (not necessarily the system, but the quality) is the “best in the world.” If it’s the best in the world, one might reason, then tinkering with the system that produces it might threaten its state-of-the-art capabilities.

Well, an interesting paper was released last month. Authored by two Urban Institute scholars, Elizabeth Docteur and Robert A. Berenson, the paper reviews dozens of studies comparing the quality of U.S. health care to that of other countries. The evidence, they conclude,

…does not provide support for the oft-repeated claim that the “U.S. health care is the best in the world.” In fact, there is no hard evidence that identifies particular areas in which U.S. health care quality is truly exceptional…. Instead, the picture that emerges from the information available on technical quality and related aspects of health system performance is a mixed bag, with the United States doing relatively well in some areas — such as cancer care — and less well in others — such as mortality from conditions amenable to prevention and treatment… Like other countries, the United States has been found to have both strengths and weaknesses in terms of the quality of care available, and the quality of care the population receives.

And they observe, rather damningly: “the main ways in which the United States differs from other developed countries are in the very high costs of its health care and the share of its population that is uninsured.”

So American health care, like that of any country, has strengths and weaknesses. Among the strengths are cancer screening and treatment, diabetes care, hip fracture treatment, and senior flu vaccination. Among the relative weaknesses are asthma care, renal disease treatment, overuse of procedures, and patient safety.

Many of these findings, it seems to me, should not be surprising:
  • The U.S. leads the world in cancer care, but the type of care cancer requires (technology-intensive, specialist-provided) is what the U.S. does well.
  • Overuse of procedures is a problem in the U.S., but the fee-for-service payment structure, widespread in the U.S., encourages overuse of procedures.
  • The U.S. has a high “amenable mortality” rate (see below), but this is most likely an “access” problem rather than a “care” problem. And of course 46 million Americans are uninsured, many more are underinsured, and health care in the U.S. is heavily rationed by price.
One hot-button issue the paper addresses is how U.S. health care compares to that of Canada. There are many comparative studies addressing this topic, focusing on such diverse problems as “cancer, coronary artery disease, chronic illnesses and surgical procedures.” But the bulk of the studies, Docteur and Berenson tell us, find “higher quality of care in Canada.” One review, for example, found that “Of 10 studies that included extensive statistical adjustment and enrolled broad populations, five favored Canada, two favored the United States, and three showed equivalent or mixed results.”

Some have argued that raw mortality numbers aren’t a decisive metric for head-to-head comparisons of different countries’ health-care systems, since lifestyle factors may play a large role in mortality outcomes. So to more narrowly focus on deaths plausibly attributable to a country’s health-care capabilities, Docteur and Berenson use the concept of “amenable mortality” —that is, deaths before age 75 from conditions considered amenable to treatment by medical care such as treatable cancers, diabetes, and cardiovascular disease. The results, however, are no more encouraging than the raw mortality numbers. And the U.S. ranking in amenable mortality, among 19 countries considered in one well-known study, somehow slipped from 15th to 19th place between the late 1990s and early 2000s:




(Data from Ellen Nolte and C. Martin McKee; diagrams from a Commonwealth Fund summary of the findings.)

What amenable mortality statistics can’t tell us is the extent to which poor health outcomes arise from poor quality of care and the extent to which they arise from poor access to care. The question matters since if access is the main problem, American health could be greatly improved by expanding secure access to more people, e.g., to people under age 65.

One passage in the Docteur-Berenson piece that caught my eye was this one about cancer care:

The United States had the highest survival rates for cancer of the colon, rectum, lung, breast, and prostate. U.S. survival rates were also among the highest for melanoma (fourth), uterine (second) and ovarian (fifth) cancer, cervical cancer (sixth), Hodgkins disease (third) and non-Hodgkins lymphoma (fourth). The United States was ninth in survival of stomach cancer. Although average survival differences between the United States and Europe as a whole were in some cases large, the difference between the United States and the other countries with relatively high five-year survival rates were generally small (approximately 3 to 4 percent for many cancers) and (due to small sample sizes) usually not statistically significant.

Then there’s this observation about younger patients:

The study also looked at cross-country differences by population group, finding that survival rates for colon, breast and uterine cancer were similar in the United States and Europe for patients under 45 years, but were much better in the United States for patients age 65 or older at diagnosis. In the case of stomach cancer, the U.S. survival rate for patients under age 45 was below those of many European nations, but similar among the older patients.

In sum the U.S. appears to be very good at cancer care for older patients, but curiously mediocre for younger ones.

The following diagrams, showing five-year survival rates for various types of cancer for different age groups (and for both sexes unless otherwise indicated), bear this out. (The U.S. is represented by the thick red lines.)



(Data: U.S.: Surveillance Epidemiology and End Results (SEER); Europe: Eurocare.*)

We find that:
  • For all types of cancer but one (pancreatic), the U.S. has the highest five-year survival rates for people 75 and older.
  • At younger age levels, U.S. five-year survival rates are above average in all areas but one (stomach), but best in only one area (Leukemia).
Thus American cancer care is indeed distinguished, but its benefits go disproportionately to people over 65, i.e., to those with secure access to health care.

What makes for effective cancer care? The biggest factor, say Docteur and Berenson (citing a study by Coleman et al.), is “access to diagnostic and treatment services.” And of course regular screening is something the uninsured and underinsured (a large segment of the under-65 population) generally lack. More broadly, better cancer survival rates “are associated with higher national income levels, higher levels of expenditure on health, and higher investment in health technology, as proxied by indicators such as the rate of CT scanners per person.”

Thus the amenable mortality numbers shown above are neither a fluke nor a product of lifestyle alone, but a reflection of a health-care system that caters well to one class of patient—elderly and suffering from emergency health conditions—but poorly to the bulk of the population. American health would obviously be much improved if all citizens could avail themselves of the care currently available to one select class of people.

*These data are if anything biased in favor of the U.S., since the U.S. data are for 1999-2005 while those for Europe are for 1995-1999 (reflecting data availability).

The NBC-Wall Street Journal Poll (released Wednesday)




Reporters must stop using the word “overhaul” to describe Obama’s health care reform plan. If what Obama wants is “overhaul,” then what do single-payer advocates want? “Major reform” is a fair descriptor. And note that that’s what a plurality of people claim they want.

What’s striking to me is how little change there’s been in public sentiment about health care reform in recent months. Note the stasis from July to August:





A possible interpretation: President Obama’s increased involvement in the debate hasn’t reversed, but may have halted, the negative slide. And when the Obama plan is explained somewhat, support seems solid. The responses graphed below were given to the following question:

“Now I am going to tell you more about the health care plan that President Obama supports and please tell me whether you would favor or oppose it. The plan requires that health insurance companies cover people with pre-existing medical conditions. It also requires all but the smallest employers to provide health coverage for their employees, or pay a percentage of their payroll to help fund coverage for the uninsured. Families and individuals with lower- and middle-incomes would receive tax credits to help them afford insurance coverage. Some of the funding for this plan would come from raising taxes on wealthier Americans. Do you favor or oppose this plan?”



The story in all of these graphs is what has happened to the “No opinion/Not sure” group. A portion has gravitated to the supportive category and a (larger) portion to the unsupportive category. But there’s little left in this group. So possibly opinions about health care reform have solidified.

But there are depressors:



Lies of the right have obviously wormed their way into the public consciousness. The good news is that countering them requires only the truth, albeit it must be shouted.

And here may be the brightest spot:



The Republican onslaught has damaged Obama, but not as much as it has the Republicans.

Inside the Asylum

Frustrating are the responses to Sarah Palin’s nutty claim about “death panels.” Howard Dean, for instance: “My wife and I have practiced medicine for over forty years combined. There is no truth now, nor has there ever been any truth to the idea that the government encourages euthanasia or infanticide.” “No truth to the idea”? But Palin’s claim was lunacy; it hardly merits empirical disconfirmation.

And here’s the New York Times reporting on the rumors of “death panels”: “Conservative critics say the legislation could limit end-of-life care and even encourage euthanasia. Moreover, some assert, it would require people to draw up plans saying how they want to die…. These concerns appear to be unfounded.” “Appear to be unfounded”? The Times can’t simply report the truth, which is that the claims are lies?

And this is the problem. A band of lunatics on the right (Beck, Hannity, O’Riley, Limbaugh, Coulter, Malkin, Savage, Boehner, DeMint, Palin, Morris, Gingrich, etc.) has gained a space in the public discourse. As trusted commentators they can say whatever they like and be believed by part of the public—claims that, even if completely crazy, must be taken seriously. 

How has this occurred? Well, nothing guarantees that the people who run the major media—and decide what is and isn’t serious discourse—aren’t glib and woefully ignorant about issues of importance. And they have perverse incentives to (a) find controversy where there’s none or should be none (global warming being the most egregious example) and (b) pose as “neutral” in the “debates” they fabricate. Thus on one side are policymakers, peering into the economic abyss, and proposing a modest, necessary reform that will expand health care coverage to millions, make existing coverage more secure, and address rapidly rising health care costs. On the other side is lunacy, sheer lunacy: comparisons of Obama to Hitler, rumors of “death panels,” people carrying firearms to Town Hall meetings, people crying over the “loss” of their country, etc.

The method of rightwing sabotage is to make outlandish claims on the assumption that the major media, rather than examining, debunking, and dismissing them (its job), will amplify them, enabling the claims to worm their way into the public consciousness. The effects can be devastating. Here are results from a Wall Street Journal/NBC poll released Wednesday:



(For the record, the first, third and fourth “criticisms” are nonsense, since no version of the health care reform bill contains any such provisions. And the reform can’t very well be a “government takeover of the health care system” if it doesn’t involve a government takeover of the health insurance and/or health care delivery industries.)

There is a legitimate debate to be had, but it’s about cost, not about whether the government is “taking over” health care, or whether government bureaucrats will get “between” patients and their doctors (as insurance companies do now), or whether there will be “death panels.” Much of the major media, however, are unable to focus on the boring facts of health care reform: that its effects for most people will be indiscernble, that if anything it will help people (by prohbiting insurers from denying coverage and by lowering insurance premiums in the long run), that reform is absolutely essential if we are to avoid a long-term economic catastrophe, and that the serious debate isn’t about Hitler or “death panels,” but cost.

Reasons for Reform

The prime motivation for health care reform is economic. In 2009 Americans will spend $2.5 trillion on health care, three times as much as in 1994 and about 17.5 percent of GDP. And in 2018 health care spending is projected to be 20 percent of GDP ($1 of every $5 spent). Health insurance premiums have risen 119 percent since 1999, more than four times the rate of inflation during that period (28.5 percent). And premium costs are projected to rise by 9 percent next year, an increase that 42 percent of employers say they will pass on to their employees.

Although health care costs have risen faster than inflation in all industrialized countries, nowhere have they risen faster than here:



(Chart from Paul Krugman’s blog; shows health care spending as a percentage of GDP.)

So other rich countries spend less than us and get health care that’s at least comparable (though see below).

Some would argue that richer countries should pay more for health care since richer populations are likely to demand more health care services. We might, for example, expect an approximately linear relationship between per capita GNP and per capita health care spending. Here’s what we find:



(Data: W.H.O.)

A straight-line relationship graphed from (approximately) Spain to (approximately) Norway fits the data reasonably well (adjusted R2 = 0.67), but reveals the U.S. as an outlier, paying $427 billion more annually than should be inferred from its wealth..

Rapidly rising health care costs are, of course, an ever-growing burden on  individuals, families, and businesses. But they’re also, as President Obama says, a “ticking time bomb for the federal budget.” No need to do the math. Just follow the graph of CBO projections of the federal budget as a share of GDP:



Obviously if trends continue debt will pile up, the dollar will weaken, interest rates will rise, and we may wind up without much of an economy to speak of. Opponents of health care reform need to grasp that failure to get control of runaway health care costs is not an option.

Morality

There are also, of course, moral reasons for health care reform. Almost 50 million Americans now lack health insurance, up from 40 million when the Clinton plan failed in 1994. Some of these are the young and “immortal,“ uninsured by choice. But the vast majority are simply priced out of the market. In any case it’s no good having anyone uninsured, since society just winds up paying their emergency bills, and exclusion of low-risk individuals from insurance pools makes everyone else’s insurance premiums higher than they would otherwise be.

Perhaps the most egregious practice of the insurance industry is rescission: the practice of retroactively canceling—often on dubious grounds that patients hadn’t disclosed their full medical histories—coverage of policyholders with expensive medical conditions. As Lisa Girion reported in the Los Angeles Times, the insurers Assurant, UnitedHealth Group, and WellPoint over a five-year period “canceled the coverage of more than 20,000 people, allowing the companies to avoid paying more than $300 million in medical claims.” The companies thus avoided paying for treatments of “policyholders with breast cancer, lymphoma and more than 1,000 other conditions” (quoted in Marmor and Oberlander, cited below). Amazingly—in what should have been a public relations disaster—in congressional testimony on June 16 executives of these companies refused to end this practice. As Theodore R. Marmor and Jonathan Oberlander observed (in an excellent article),

There is no stronger indictment of American private insurers or better example of the profit motive’s corrosive influence on medicine than rescission. That insurers, even with political pressure for reform, would not forswear this practice in public hearings is stunning. It also illustrates how difficult a task it will be to transform the business practices of an industry that profits from discriminating against sick people.

Insurers claim that rescission affects only a small percentage of policyholders. But the vast majority of health care coverage claims are made by a small percentage of policyholders. So among this group, rescission looms relatively large.

In any case, all versions of the health care reform bill before Congress would end rescission (though arguably if the public option isn’t in the final bill such prohibitions may lack teeth).

Two other points about morality:
  • The Institute of Medicine estimates (2004) that about 18,000 Americans die every year for lack of health insurance.
  • A Harvard study found that over 60 percent of all bankruptcies are caused at least partly by medical expenses.
Quantitative international comparisons along the latter two dimensions are impossible since the number of deaths caused by lack of health insurance and the number of bankruptcies associated with medical costs in all other industrialized countries are zero. The trail of ruined (American) lives would make us, the richest country in the world, a laughing stock were it not so tragic.

“Best Health-Care System in the World”?

One argument opponents of health care reform can’t make (but will) is that the American health-care system is the best in the world. How good is American health care? Plausibly, for those with full access to it, it’s relatively good. But for those with little or no access to it, it’s almost certainly the worst in the industrialized world. Let’s examine some of the (admittedly tired) statistics about health outcomes. First, the World Health Organization’s “healthy life expectancy” statistic, i.e., average number of years a person lives in “full health” (a measure of the resources devoted to reducing the impact on people’s lives of major diseases):



Then there are our famous achievements in infant mortality:



But it isn’t just infant mortality, but mortality throughout life, that distinguishes the U.S.:



(Source: W.H.O.)

And here’s something interesting. Disproportionately large percentages of Americans, compared to citizens of other industrialized countries, die at every age level until after age 65, at which time the differences converge towards statistical insignificance. 65, of course, is the age at which access to health care finally becomes secure for Americans (as it is for citizens of other industrialized countries throughout life):





(Source: W.H.O.)

Some have argued that our poor health outcomes aren’t the fault of our health-care system, since lifestyle factors may play a role—what Ezra Klein called the “we eat more cheeseburgers” argument. Our diets may on average be poorer than those of comparable societies (though I’m not sure about this). We certainly have more homicides. On the other hand, we smoke less than most:



So lifestyle factors may be a wash. In any case the argument of most health care reform advocates is not that our health care outcomes are worse than those of other countries, but that they’re no better, even though we spend more than twice as much per capita as most others do. Something is clearly greatly amiss.

And what about consumer satisfaction? In surveys the U.S. system doesn’t stack up well against those of other countries. The 2008 Commonwealth Fund International Health Policy Survey of Sicker Adults (p. 3), for example, asked heavy health care users in eight countries to rate their satisfaction with their health-care systems. There were three choices: highly positive (“works pretty well”), intermediate (“some good things” but “fundamental changes are needed to make it work better”), and strongly negative (“has so much wrong with it”). Here are the percentages of respondents that chose the highly positive and the strongly negative responses:


Components of Proposed Reform

The type of system the Democrats have in mind is fairly simple (all obfuscation aside). It has four components (or pillars; see Krugman):

1. Regulation, so that no one can ever be denied coverage, whether because of pre-existing conditions, rescission, lifetime limits on payments, or anything else.
2. Subsidies, so that everyone can afford health care coverage.
3. Mandates on individuals and families to buy insurance, and on businesses to provide insurance to employees or pay a fee to help subsidize coverage for lower-income people.
4. Competition through local and/or national insurance exchanges and possibly a competing public option.

The parts fit together coherently. Regulations that require insurance companies to insure all comers would be unworkable without mandates, since people would otherwise game the system, buying insurance only when they’re sick. Mandates would be unworkable unless there are subsidies to relatively low-income people so they can afford the insurance they’re mandated to buy. Subsidies would be unworkable unless there are cost control measures, including mandates, which lower premiums by expanding insurance pools, and competition, whereby insurance companies would compete through organized exchanges and possibly against a public option, pushing down premiums.

Most media coverage leaves the impression that Congress is mired in controversy over health care reform. To a degree, yes. But the broad parameters of the proposed reform, outlined above, are non-controversial. The main differences concern (a) whether there will be a public option, and (b) how to pay for the subsidies portion of the bill, i.e., cost.

More About Bubbles

There are two reasons to buy an asset. One is to gain a stream of income that arises from the economic activity that the asset supports. The other is to profit by selling the asset when its price changes. The former is “investing,” the latter “speculating.” The two motives are distinguishable, but often both are involved in the purchase of an asset. That is, in buying an asset you typically seek a stream of income in the form of dividends or interest, but you’re also trying to buy low and sell high.

This duality of motive is in some degree unavoidable. Financial markets require liquidity, the ability to quickly sell assets considered overvalued and buy ones considered undervalued. So profiting by anticipating price changes is integral to financial markets.

And many would argue that that’s as it should be. You can sell an asset you think is overvalued. But the fact that you can sell it means there’s a market of individuals out there of varying perspectives who think it’s worth that price. And generally there should, according to theory, be constant pressures from supply-and-demand forces pushing prices toward “intrinsic” values. As an embodiment of the collective wisdom of multitudes of investors, markets, most economists believe, are good at setting prices.

But how good are they, really? It depends on a key assumption: that investors are, on average, “rational.” Behind the supply and demand for an asset could lie rational valuations based on “fundamentals.” Or not. Price movements could be based on anything—whim, line patterns on charts, unfounded beliefs, astrology. We can’t know from the prices themselves why people believe those prices are justified. And surely, from time to time, groups of investors will get wrong ideas about assets’ proper values and bid prices in the direction in which they think they will go. Their belief is then “justified,” triggering a perverse feedback that could drive the price still further off course. What could now happen is that savvier investors, recognizing the bubble for what it is, exploit an arbitrage opportunity and bring prices back to rational levels. Or they might try to ride the bubble as it expands, inflating it still more, and calculating when to get out (leaving the innocent holding the bag). If enough parties believe there’s now something new in the nature of things—e.g., that prices in this asset category can only rise, or that risk has been controlled though financial innovation—then leverage (debt financing of asset purchases) should come into play. After all, if it’s a sure thing, why not multiply your returns through leverage?

This seems, to me at least, a plausible scenario of how asset bubbles might form. I’ve tied the possibility of bubbles to the dual motives for purchasing assets—investing and speculating—with the speculative component enabling prices to stray far from “intrinsic” values. But more fundamentally what enables bubbles to form is simply the fact that people price assets. “Laboratory” experiments have found that even in the absence of speculation (i.e., in laboratory asset pricing games where participants can purchase but not resell assets) bubbles almost invariably form. Nevertheless I strongly suspect that in the real world, for bubbles to reach the pathological proportions of the most famous (and destructive) bubbles, a speculative component is necessary.

So bubbles are a regular feature of capitalism. Famous ones include the “Tulipmania” in Holland, 1634-37; the South Sea Company bubble in England, 1720; the Mississippi Company bubble of 1720; the “Railway Mania” in the U.S. in the 1840s; the U.S. stock market bubble of 1928-29, the “Nifty Fifty” bubble in U.S. stocks in the late 1960s and early 1970s; the Japanese stock market and real estate bubble of the 1980s; the U.S. tech bubble of 1995-2001; the U.S. housing bubble of 1998-2006; and property bubbles in recent years in such places as the U.K., Ireland, Spain, and Romania. The common feature of all bubbles is that people buy an asset because they expect its price to keep rising.

Which brings us back to the question: why did economists miss the housing bubble? (And why, especially, did the Fed miss it?) As I noted in this space last week, one factor was the scientific pretensions of the discipline, which led economists to favor a single, seemingly more accurate, formula (the user cost formula) over conventional indicators of bubbles. Here are three more:

1. An Ideological Predilection to Believe Markets are Efficient

This is the underlying reason economists failed to see a bubble, all other reasons being subsidiary. If markets are efficient, there can be no bubbles. People will value assets rationally, using all available information to make buying and selling decisions. Asset prices will then be anchored to fundamentals.

Of course, efficiency is a matter of degree, and no economist believes markets are always perfectly efficient. But most economists simply doubt that irrational price movements will go very far before the disciplining hand of the market intervenes to bring prices back to justified levels. This view was expressed by then Federal Reserve Board Governor Ben Bernanke in a 2002 speech in which he argued against the idea of a “bubble-popping” Fed:

[P]rices of equities and other assets are set in competitive financial markets, which for all their undeniable foibles are generally highly sophisticated and efficient. Thus, to declare that a bubble exists, the Fed must not only be able to accurately estimate the unobservable fundamentals underlying equity valuations, it must have confidence that it can do so better than the financial professionals whose collective information is reflected in asset-market prices.

Bernanke’s argument is that markets have greater insight into the “unobservable fundamentals” than the Fed has; therefore the Fed shouldn’t diagnose bubbles that market participants don’t themselves see. But there’s a problem. We know from history (and from the tech bubble not a couple years before Bernanke’s speech) that bubbles occur. And we know that most participants in bubbles don’t view themselves as being in a bubble. Can a methodological assumption (that economic agents are rational) that rules out a certain phenomenon entail that the phenomenon doesn’t occur? No. But it can blind one to it.

A bubble means people buy an asset because they expect its price to keep rising. To determine whether a housing bubble exists—to observe the “unobservable fundamentals”—therefore, we need to get into the heads of homebuyers. One way is through “external” indicators like price-to-rent and price-to-income ratios, which should suggest whether prices are off course. Another would be through “internal” indicators like a survey of homebuyer sentiment. That way, however, was blocked during the bubble years by the prevalent methodological assumption of rational expectations. Which isn’t to say surveys of homebuyer sentiment weren’t performed, only they were performed by economists somewhat out of the mainstream. The only serious survey of homebuyer opinion during this period appears to have been Karl Case’s and Robert Shiller’s survey for their 2003 Brookings paper. Their findings were not encouraging for the efficient market hypothesis:

Many of the answers [about interest rates, a dominant theme in people’s responses] to these questions are disappointing. Typically the answers read like random draws from the business section of the newspaper, or else the respondents refer to casual observations that one might make just driving around town. Respondents presented no quantitative evidence and made no reference to professional forecasts. One should not be surprised at this, however. After all, the single-family home market is a market of amateurs, generally with no economic training. Once more we see evidence that in neither period [including in 1988 when the authors conducted a similar survey] did many homebuyers perceive themselves to be in a housing bubble. References to market psychology were quite rare.

The most shocking finding from the survey was that the average expected annual rate of home price increase over the next ten years (survey conducted in 2003) among recent homebuyers was 13 to 15 percent. That is, respondents on average expected house prices to rise by between 13 and 15 percent each year over the next ten years. Increases like this were common in the bubble years, but the average annual rate of home price increase from 1987 to 2008 (which includes the bubble years) was about 4.7 percent. And in non-bubble years the rate has pretty closely tracked inflation, which since 1914 has averaged 3.41 percent per year. If the survey respondents understood the question they were being asked, then their perceptions of reality are seriously out of whack. If they didn’t understand the question, then their knowledge of basic economic concepts is seriously out of whack. Either way, it’s hard to reconcile the portrait of the homebuyer that emerges from this survey with that of the rational economic agent most macroeconomic models assume. The latter assumption, of course, is the lynchpin of the view that markets are efficient.

Overall, Case and Shiller found from their survey “that elements of a speculative bubble in single-family home prices—the strong investment motive, the high expectations of future price increases, and the strong influence of word-of-mouth discussion—exist in some cities.” Additionally they found, from an econometric analysis of factors that may have caused the run-up in house prices, that while “income alone explains patterns of home price changes since 1985 in all but eight states,…we cannot reject the hypothesis that a bubble exists [in the other eight states].” Though Case and Shiller state their results cautiously, their conclusion, from two sorts of evidence (their homebuyer survey and their econometric analysis), is clear: there may well be a housing bubble.

2. Obliviousness of Popular Culture

Another source of information about homebuyer sentiment, albeit not scientific, is the popular media. Case and Shiller found, from a Lexis-Nexis search of newspaper and wire service articles, that use of the term “housing bubble” increased dramatically beginning in 2002. Another indicator: from 2002 to 2005 The Economist magazine ran a series of articles with titles like “Castles in Hot Air,” “House of Cards,” “Bubble Trouble,” “Betting the House,” “Going Through the Roof,” “Still Want to Buy?”, “Will the Walls Come Falling Down?”, “In Come the Waves,” “After the Fall,” and “Hear that Hissing Sound?”

By 2005 there were many on-the-ground media accounts of people clearly engaged in what could only be called “bubble behavior.” A March 2005 New York Times article began:

Real estate-crazed Americans have started behaving in ways that eerily recall the stock market obsession of the late 1990’s.

In Naples, Fla., some houses have been bought twice in a single day, an early-21st-century version of day trading. Buying stocks on margin has morphed into buying homes with no money down. The over-the-top parties of Internet start-ups have been replaced by flashy gatherings where developers pitch condos to eager buyers.

Five years ago, the cable channel CNBC sometimes seemed like a backdrop to daily American life. Its cheery analysis of the stock market played in offices, in barbershops, even in some bars. Today, ‘Dude Room,’ ‘Toolbelt Diva’ and other home-improvement shows are the addictive fare that CNBC’s exuberant stock shows once were.

’It just seems like everyone is doing it,’ Laurie Romano, a 26-year-old self-described real estate investor, said with a giggle as she explained why she was attending an open house this month for the Nexus, a 56-unit building going up in Brooklyn’s chic Dumbo neighborhood. She and her fiancé, a dentist, had already put down a deposit on a Manhattan condo earlier in the week and had come to look at another at the Nexus.  (“Trading Places: Real Estate Instead of Dot-Coms,” Motoko Rich and David Leonhardt, New York Times,  3/25/05)


A Los Angeles Times story of the same week tells of Chris Boome, an insurance agent in Burlingame, California who, at 58, “knows he hasn’t saved enough to retire,” and so “a few weeks ago…sold most of the mutual fund shares and used the cash to buy an $83,500 chunk of land in the Nevada hills, a stretch of ground he had seen only in a photograph…. ‘This is more exciting than a mutual fund,’ Boome said. ‘It feels safer too. You buy a piece of dirt, you feel you’ll always have a piece of dirt’.”

The article continues:

The astounding rise in home values is enticing many middle-class Californians to bet on dirt, gambling their retirements that they can do better with property than with any other investment. In the same way that the stock market’s apparently limitless ascent in the late 1990s seduced investors into buying shares in untested dot-coms, relentlessly rising house and land prices are spurring people to do things that used to be considered unusual – if not irresponsible…. They’re cashing in retirement funds, selling stock and taking out second mortgages. They’re pouring the money into real estate, often in distant states, often without seeing the property.” (“Putting Stock in Property,” David Streitfeld, Los Angeles Times 3/27/05)

(And there is a lot more of this. See also “What Happens if it Bursts?” Marek Fuchs, New York Times, 3/27/05. And note this sampling is all from one week in March of 2005.)

This is not to say that journalism is science, but it can capture cultural trends that economists and others who should care about the potentially destructive effects of price distortions might heed. Further along these lines, the role of cable television in pushing prices off course—of CNBC and programs like “Flip This House”—should be examined. One can reasonably ask: If such programs exist, isn’t there a bubble? For they are megaphones that blare to the entire country messages like “House prices can only rise; invest now,” or “Tech stocks can only rise; invest now.” Obviously some portion of the American public will take these messages seriously. The development of such media enable these virulent memes to be transmitted nationally, making the intrinsically local phenomenon of a housing bubble a national one.

3. Obliviousness of the Subprime Phenomenon

In literature of the bubble years that considered the possibility of a housing bubble—even that that found a bubble likely—the word “subprime” almost never appeared. Within the Fed, one Federal Reserve governor, Edward Gramlich, repeatedly raised concerns about subprime lending practices, but was consistently rebuffed by Fed chair Alan Greenspan. But otherwise few voices anywhere noted the problem—wherein lies the general failure of economists to predict the crisis. For even if one knew about the housing bubble, unless one also knew about the absurd products being pedaled by the subprime lending industry (option ARMs, stated-income loans, piggy-back loans, for example), and the role of securitization in financing them, one would not have been able to connect the housing bubble to the credit crisis, let alone the near collapse of the economy.*

On the other hand, had economists known about subprime lending practices and about the nature of the financing of subprime loans, then predicting the credit crisis would have been like putting two and two together. So why were most economists oblivious of the subprime problems? One must suspect their credo: the view that markets are efficient—which fostered an overconfidence in markets and in market participants and a predisposition to regard all capitalistic competition (including that that engendered option ARMs, alt-A loans, mortgage-backed securities, and credit default swaps) as healthy.

Of course, this trusting attitude blinded economists not just to problems in the subprime market, but to the housing bubble generally, awareness of which was a prerequisite for predicting the general crisis.

In short, signs of a bubble were everywhere. The failure of most economists to see them surely ranks as one of the worst-ever performances by a body of experts. It suggests that a reconsideration of the foundations of economics is in order.

*For the record, I knew about the housing bubble, thanks to Dean Baker and Paul Krugman, but not about the impending brush with Great Depression 2.

Why Did Economists Miss the Housing Bubble?

A big question historians will ponder for decades if not centuries is why so few economists saw the crisis coming. What happened is more or less well known. The bursting of the housing bubble caused a wave of defaults and foreclosures, which caused values of mortgage-backed securities to plummet, which meant many financial institutions were suddenly undercapitalized, which caused a contraction of borrowing and lending (a credit crisis). Compounding the problem were debt-to-equity ratios of some financial institutions now deemed unacceptable and the fact that efforts to deleverage, i.e., sell assets to replenish banks’ balance sheets, caused asset prices to fall further (the paradox of deleveraging).

So cause and effect are relatively clear. What’s unclear is why so many economists missed signs of the crisis. To be fair, interactions in a complex network of variables are hard to predict. So perhaps few should have anticipated the adverse effects the bursting of the housing bubble would have on the balance sheets of too-big-to-fail banks. But most economists also missed what should have been the most obvious point of fragility in the system, the housing bubble. Indeed, most economists who considered the possibility of a housing bubble seem to have actually rejected the idea. How could this be?

First, let’s consider why anybody should have thought there was a housing bubble in the first place. People should have thought there was a bubble because of conventional indicators of bubbles. These were (1) house prices rising faster than inflation over an extended period, not a common occurrence, (2) house price-to-income ratios rising well above historical norms, and (3) house price-to-rent ratios rising well above historical norms. Here’s an illustration of indicator (1): the CPI versus the Case-Shiller index of house prices during the bubble years:



And since housing bubbles are local, we should see even more pronounced price surges in densely-populated, high-prestige regions (note the comparison to lower-density, lesser-prestige locales):



Similarly shaped curves are found in plots of price-to-income and price-to-rent ratios.

So there was a surge in house prices. The question was why. As many observed, rising prices don’t necessarily mean there’s a bubble. Prices could rise because of changes in “fundamentals,” i.e., changes in income, employment, interest rates, demographics, etc., all of which relate to the desirability and affordability of houses and so are reasons why people might rationally pay more (or less) for houses.

In a bubble, by contrast, people buy because they believe prices will continue to rise. So they may buy as an investment, expecting their wealth to grow as their home appreciates, or they may intend to “flip” their house when its price rises. Or they may be anxious that rising prices will make a home unaffordable if they wait, so they buy now. Since mortgage debt in such a situation is undertaken not on the basis of expected income, but of expectations of continually rising house prices, when house prices start to fall, as they must, people will be stuck with unsupportable debt. The result is a crash, the sort of thing we’ve seen in the last three years.

So why did economists miss the housing bubble? Reasons are multiple. They include an ideological predilection to believe markets are efficient and a general obliviousness of the subprime phenomenon. But more curious is that many economists who considered the possibility of a bubble actually rejected it.

Two papers, one by Jonathan McCarthy and Richard W. Peach (2004) and one by Charles Himmelberg, Christopher Mayer and Todd Sinai (2005)—both influential in convincing many economists there was no bubble—rejected conventional bubble indicators in favor of a different formula, the “user cost of housing.” The latter, they argued, in contrast to the conventional indicators, captures the total annual cost of owning a home. “The key mistake committed by the conventional measures of overheating in housing markets,” wrote Himmelberg, Mayer and Sinai, “is that they erroneously treat the purchase price of a house as if it were the same as the annual cost of owning.” McCarthy and Peach similarly criticized the conventional indicators (price-to-income and price-to-rent ratios) on the grounds that “neither measure takes interest rates into account.”

The user cost of housing, by contrast, includes not just the price of the house, but also less obvious costs and benefits of owning a home. These include the risk-free rate of interest (an opportunity cost, since it’s a return one could have earned had one invested in Treasury securities instead), property taxes, maintenance costs, a “risk premium” (i.e., a “cost” implicitly incurred in purchasing a house rather than renting because of the greater financial risk of home ownership), plus benefits like tax deductions (for mortgage interest and property taxes) and capital gains from the appreciation of home value. The formula is then

     P[irf + tP - tD(iM + tP) + M + RCG]                 (1)

where P is the price of the house, irf is the risk-free rate of interest, tP is the annual property tax rate, tD is the tax deduction rate (deducting for mortgage interest iM and property taxes tP), M is the fraction of home value spent on maintenance, R is the risk premium, and CG is capital gains (or losses) from appreciation (or depreciation) of the house. (Readers needn’t strain their eyes or their brains trying to understand this formula. It’s enough to know that “user cost” is an attempt to include everything that might affect the true “cost” of a house in one formula.)

Another expression for this formula is “imputed rent,” since it’s the effective cost of living in a property for one year. And in equilibrium the imputed rent should equal the actual rent R on comparable housing:

     RP[irf + tP - tD(iM + tP) + M + RCG]           (2)

Both groups of researchers found that in the early 2000s through 2004, in every major metropolitan area, the imputed rent was lower than the actual rent on comparable housing. This means that house prices, far from being too high, were too low!

How did the researchers explain the dramatic rise in nominal house prices? The formula can be rearranged to give the equilibrium price-to-rent ratio:

     P/R = 1/[irf + tP - tD(iM + tP) + M + RCG]       (3)

So in equilibrium the price-to-rent ratio would be the inverse of the user cost of housing And thus if, say, interest rates (irf) were to fall, the equilibrium price-to-rent ratio would rise. And this, these researchers argued, is what happened in the early 2000s. Low interest rates (and so also low mortgage rates and a lower opportunity cost of capital) made houses much more affordable during this period in terms of “user cost.” Homebuyer decisions were thus rational, based on affordability. No bubble.

But here’s the problem. The formula assumes fixed interest rates. And of course what precipitated the bursting of the housing bubble were resets, i.e., upward shifts in variable interest rates that made many subprime mortgages suddenly unaffordable. House prices then started falling. The rest is history.

Thus the user cost concept had an Achilles’ Heel. The more general problem, however, is that the user-cost formula is an attempt to include everything in one formula. The reason for its supposed superiority to conventional bubble indicators is that it represents the total cost of home ownership. But the resulting formula is brittle. If something should go wrong in the parameterization, e.g., that a basic feature of the subprime mortgage market (variable interest rates) was left out, the model would likely blow up. And that’s what happened.*

Had economists stuck with conventional indicators of bubbles—and to be fair, some, like Dean Baker, Robert Shiller, and Paul Krugman, did—the bubble would have been widely recognized for what it was. And concerted action against it—perhaps in the form of “a robust denunciation of speculators and speculation by someone in high authority,” as John Kenneth Galbraith suggested may have prevented the 1929 crash—might have been taken. But economists fell victim partly to the scientific pretensions of their discipline—which values sophisticated, seemingly precise, general formulae—and partly to an ideological predilection to regard markets as efficient. Most humiliating, however, is that economists, like the direct victims of the subprime meltdown, were snookered into believing that houses were more affordable than they were. The fact that interest rates on subprime mortgages were often variable rather than fixed wasn’t widely advertised and was even deliberately hidden. Economists should have been less enamored of the invisible hand of the market and more attentive to that of the subprime lenders who hid the true costs of housing.

*It should also be noted that both studies used biased data. Data for the studies came from the Office of Federal Housing Enterprise Oversight (OFHEO) index, which covers only houses with “conventional,” i.e., prime, mortgages purchased by Fannie Mae and Freddie Mac. The analyses were thus confined to houses purchased with low, fixed-rate mortgages of no more than $359,650. Also, condominiums were excluded. Obviously, if you’re considering only prime mortgages, not subprime or alt-A, etc., and excluding condominiums, which were a major problem in some locales, e.g., Miami, the real problem could be entirely missed.
