I have deliberately kept this story stylized, omitting the juicy details about complicated derivative securities that seem to bear only the most tenuous connection to the everyday economic realities of production, employment, consumption, and so on. I have also ignored the even juicier details of greed, stupidity, and corruption. Posner does not ignore those things. They provide an irresistible target for amusement and contempt. I wanted instead to focus on the central role of leverage, because it is leverage that turns large banks and financial institutions into ninepins that cannot fall without knocking down others that cannot fall without knocking down still others. That seems to be the key to the potential instability of an unregulated financial system. It happens without any of the private actors violating the canons of self-interested rationality. Those canons would have been different if the SEC, the Fed, and other institutions charged with regulation had insisted both that all transactions be made public and that there be some limits on leverage.
It is a noteworthy intellectual event that Posner has come to this understanding and expressed it forcefully and fearlessly. This same understanding must then also be the key to designing regulations that can reduce the frequency of financial crises like the current one, and limit the collateral damage to the real economy that they entail. Regulation should require that the uses and amounts of leverage, still largely hidden, be made public and that limits be set on the amounts of leverage that financial institutions can bring into play.
Now let me turn to the recession itself. Posner prefers to label it a “depression”—see his subtitle—as if there is some unambiguous dividing line that has been crossed. He defines a depression as a “steep reduction in output that causes or threatens to cause deflation and creates widespread public anxiety and, among the political and economic elites, a sense of crisis that evokes extremely costly efforts at remediation.” All sorts of obvious questions arise. How steep? How many prices must fall for how long to qualify as deflation? “Core” consumer prices—meaning prices for all consumer goods and services exclusive of energy and food—had not fallen at all at the end of 2008. Even more recently, decreases in the price indexes have been few and sporadic. Wage rates have not fallen either, still less so when benefits are added in. Anyhow, one should mean by “deflation” a cumulative, sustained fall in prices, not a scattered episode. Deflation is certainly a “threat.” In a time of roughly stable price level, any recession entails a threat. My guess is that Posner overstates it. Finally, a “sense of crisis” seems merely to replace one vague word by another.
I am going to stick with “recession.” Posner thinks this is a euphemism in aid of denial. No: we are in a long and serious recession. When it is over we will be able to estimate roughly how much production was lost in the course of it. But I want to avoid the suggestion that something qualitative happened at the end of 2007 or sometime in 2008, over and above the combination of recession and the financial breakdown, or that we are on our way to the 1930s, which is grossly unlikely. What is important is the interaction of the “real” recession and the financial crisis. I mentioned at the beginning that they are reciprocally cause and effect, and that is what I want to clarify, at least broadly.
Posner starts the story, reasonably enough, with the period of easy money and low interest rates that began in 2001 as the Fed’s normal response to the recession of that year, and lasted until the middle of 2004. There was plenty of liquidity—money, or assets that can be readily turned into money—and one result was a housing boom. In fact, construction had already increased pretty sharply during the prosperous 1990s, in spite of generally unfavorable demographics, such as the aging of the population and the corresponding slowdown in family formation, both of which diminish the need for living space.
But there was certainly a further spurt. About 1.2 million private housing units were started in 1990, 1.6 million in 2000, and 2.1 million in 2005. Posner emphasizes the corresponding run-up in house prices, and he is right to do so. But the housing boom was not just a financial fact. By 2005 the country had clearly built many more houses, maybe two or three million more, than it could afford to occupy and finance. There would have been a housing slump in any case. We have had housing booms and slumps before, with consequences no worse than an interval of slow growth or a brief downturn, met with normal monetary policy and automatic fiscal stabilizers such as changes in tax rates or in public spending.
What made this housing boom different, of course, was the mix of low interest rates and the ability of the original lenders to package many thousands of mortgages into mortgage-backed securities that could be sold off to the broad capital markets, where the buyers could have no real grasp of how risky the underlying mortgages were. (The rating agencies that were supposed to figure it out for them were waist-deep in conflicts of interest. Moody’s and Standard and Poor’s were paid by the same institutions whose securities they were supposed to be judging.) As a result, trillions of dollars of mortgages were sold, unscrupulously and deceptively, to buyers whose only chance of meeting their obligations was a continued rise in prices. (I remember a ubiquitous TV commercial for a mortgage finance company whose punch line was: “When others say No, Champion says Yes.” I haven’t seen it lately.)
So this housing boom was enhanced by riskier and more opaque financial products that entangled a wider variety of highly leveraged financial institutions. The word “bubble” is often misused; but there was a housing bubble. Rising house prices induced many people to buy houses simply because they expected prices to rise; those purchases drove prices still higher, and confirmed the expectation. Prices rose because they had been rising.
To make matters worse, the fever spread to other assets: stock prices doubled in the five years 2003–2007. When the implosion came in 2007, enormous amounts of what had been perceived as wealth—true, eventually spendable wealth—simply disappeared. According to data compiled by the Federal Reserve, household wealth in the US peaked at $64.4 trillion in mid-2007, and had plummeted to $51.5 trillion at the end of 2008. Something like $13 trillion of perceived wealth vanished in not much more than a year.
Nothing concrete had changed. Buildings still stood; factories were still just as capable of functioning; people had not lost their ability to work or their skills or their knowledge of technology. But a population that thought in 2007 that they had $64.4 trillion with which to plan their lives discovered in 2008 that they had lost 20 percent of that. A standard, empirically tested rule of thumb is that an additional dollar of wealth induces the average consumer to increase annual spending by an amount between four and six cents. So we are looking at a potential drop in consumer spending of something like $650 billion a year (5 percent of $13 trillion).
To see how big this is, remember that President Obama’s stimulus package amounted to less than $800 billion, spread over two or more years. If every dollar of stimulus were translated into a dollar of spending, this particular consumer-spending gap would still not be filled. And not every dollar of stimulus will be spent; nor is the consumer-spending gap the only demand failure we have to worry about. But this is one very important route by which the financial collapse damages the real economy. Another, of course, is the paralysis of credit markets, limiting the ability of legitimate businesses and families to borrow and spend. Much the same thing seems to be happening in Europe and in Asia, with national differences in detail.
Judge Posner does not quite get the role of the consumer right. He says that among the “immediate causes of the depression were the confluence of risky lending with inadequate personal savings…so that people couldn’t reallocate savings to consumption.” He is referring to the fact that American families, who were saving 7 or 8 percent of their after-tax income not so long ago, had brought their saving rate down to less than 2 percent on average in the years between 2001 and 2008. If they had saved more they would find it easier to maintain their consumption spending in hard times.
But from the rational individual’s point of view, the goal of saving is to add to one’s wealth, to be used eventually in whatever way seems best. If your wealth is increasing anyway—as it was—there is less need to save from current income. The problem was that bubble-generated wealth is very unreliable, to put it mildly. Judge Posner is much too smart to expect the average household to see exactly how much of its apparent wealth was at risk in an unregulated, highly leveraged, deeply opaque, generally shortsighted financial system. Besides, there is plenty of evidence that many people rarely, if ever, alter their 401(k) allocations and, when they do, are very likely to alter them unwisely.
Most commentary, at large, in Posner’s book, and in this review, has been about how the financial collapse damages the real economy. It might be thought that somehow fixing the financial mess would automatically fix the real economy. That is not so, for at least two reasons worth mentioning. In the first place, all that vanished wealth cannot be restored; much of it was fluff, as we now know. American families are not worth $64.4 trillion. There is no way to know now whether they are worth more than $51.5 trillion or less. When all that shakes itself out, both the real economy and the financial system will be different.
Secondly, the restoration of credit flows is not just a matter of clarifying and strengthening the balance sheets of banks and other lenders. It takes two to make a loan: a solvent and willing lender and a credible borrower. In a deep recession, there are not enough credible borrowers, meaning businesses and individuals with excellent prospects of being able to repay a loan on time, with interest. That is why direct stimulus has to accompany the necessary work of cleaning up the debris cluttering the financial system, by removing those toxic assets from the balance sheets of banks and replacing them with clean capital.
There are other weaknesses in Posner’s remarks on the real economy. For example, more than once he says that the various antirecessionary measures—like fiscal stimulus, bailouts—are very “costly” and “may do long-term damage to the economy.” He does not explain what these costs and damages are. Sometimes he seems to have budgetary costs in mind. But bailouts are mostly transfers from one group in society to another, for example from taxpayers to financial institutions and their owners. They are certainly not ethically satisfying transfers, but it is not clear how they do long-term damage to the economy. The components of a fiscal stimulus package are costs to the federal budget; but to the extent that they put otherwise unemployed labor and idle industrial capacity to work, they do not impoverish the economy; in fact, they enrich it. (Of course, one would prefer useful projects to wasteful ones.) If fiscal stimulus works, even imperfectly, there is no doubt which way the benefit–cost ratio goes.
Posner is on much firmer ground in worrying about the very large increases in the money supply and in the interest-bearing public debt that are left behind by antirecessionary policy. Even there, we do not know how skillful and lucky the Federal Reserve will be at mopping up excess liquidity when the economy recovers, whether by arranging repayment of loans it has made to the private sector, or by selling off the assets it has acquired along with Treasury debt. And if the economy can be restored to normal growth and sensible fiscal policy, the ratio of debt to GDP, which is what matters, can eventually be brought down. Without some analysis, this sort of talk does not spread light.
There is an even odder chapter called “A Silver Lining?” In it Posner flirts with the idea that a recession, even a depression, has a good side. It weeds out inefficient firms and practices. This is a little like saying that a plague is not all bad: it cleans up the gene pool. No doubt there is some truth to this idea of a purifying effect. But the notion that it could possibly compensate for years of lost output and lost jobs seems wholly implausible. There is certainly no calculation of economic costs and benefits behind the thought of a “silver lining.” I think it is another example of overemphasis on minor gains in efficiency and neglect of first-order facts.
Posner’s chapter on “The Way Forward” is all of sixteen pages long, and fairly disorganized pages at that. This means he does not seriously try to imagine what an effective regulatory regime for financial markets would look like or, above all, how it could be designed to protect the real economy as much as possible from damage inflicted by financial breakdown. Nevertheless he says some useful things; and it is especially significant that they come from a leading conservative (even if never a tamely doctrinaire one). Here is a representative statement:
Other regulatory changes might be desirable, such as limiting leverage; raising credit-rating standards and changing how credit-rating agencies are compensated; forbidding proprietary trading by banks (that is, trading of their equity capital, which puts that capital at risk); adjusting reserve requirements to take more realistic account of the riskiness of bank’s capital structures; requiring greater disclosure by hedge funds and private equity funds; requiring that credit-default swaps be traded on exchanges and fully collateralized; and even resurrecting usury laws.
In addition, he is clear that the enormous collection of federal and state agencies with various regulatory responsibilities over financial institutions has to be somehow consolidated and unified. Also, though he is unnecessarily ambiguous, a new streamlined regulatory apparatus has to apply to most of the financial sector, including hedge funds, not just the proper banks. If this is not done, new but just as dangerously risky and opaque practices will find their way between the cracks; and no agency will have the capacity or the responsibility to detect oncoming trouble.
Obviously that laundry list is not a blueprint for reform. It seems to me that effective limits on leverage, even if they have to be different for different classes of institutions, are basic to controlling the potential instability of the financial system. Even with more transparency, extreme leverage is what generates extreme uncertainty and systemic risk. And it also encourages the dangerous compensation practices that Posner pillories. Leverage allows a clever player to manage enormous sums; it is then irresistible to focus on the short run and skim off mind-boggling paychecks and bonuses before the opportunity goes away.
The Obama administration has been trying to inject enough clarity and capital into the balance sheets of banks so that they can resume providing credit for businesses and consumers. The job of regulatory reform has had to wait. The hints we have had suggest that the administration understands the need to include the unregulated institutions, and to set up at least an early warning system to detect major risks before they arrive. But there is no way yet to know what form the new system will take. One would like to establish some principles before we forget how bad it can get.
The financial system does have a useful social function to perform, and that is to make the real economy operate more efficiently. Some human institution has to collect a nation’s savings and put them at the disposal of those who have productive ways to use them. Risks arise in the everyday business of economic life, and some human institution has to transfer them to those who are most willing to bear them. When it goes much beyond that, the financial system is likely to cause more trouble than it averts. I find it hard to believe, and I suspect that Judge Posner shares my disbelief, that our overgrown, largely unregulated financial sector was actually fully engaged in improving the allocation of real economic resources. It was using modern financial technology to create fresh risks, to borrow more money, and to gamble it away.
As far as I know, no one has a clear sense of the social value of our deregulated financial industry, with its free-wheeling banks and hedge funds and private equity funds and all the rest.
That is already a hint that he thinks its social value is limited. As Posner sees it, talk about greed and foolhardiness is comforting but not useful. Greed and foolhardiness were not invented just recently. The problem is rather that Panglossian ideas about “free markets” encouraged, on one hand, lax regulation, or no regulation, of a potentially unstable financial apparatus and, on the other, the elaboration of compensation mechanisms that positively encouraged risk-taking and short-term opportunism. When the environment was right, as it eventually would be, the disaster hit.
