Hedgehogs and foxes

Nicholas Kristof reviews research on 82,000 predictions by 284 "experts" to find what characteristics are associated with success.

Indeed, the only consistent predictor was fame — and it was an inverse relationship. The more famous experts did worse than unknown ones. That had to do with a fault in the media. Talent bookers for television shows and reporters tended to call up experts who provided strong, coherent points of view, who saw things in blacks and whites. People who shouted — like, yes, Jim Cramer!

Mr. Tetlock called experts such as these the "hedgehogs," after a famous distinction by the late Sir Isaiah Berlin (my favorite philosopher) between hedgehogs and foxes. Hedgehogs tend to have a focused worldview, an ideological leaning, strong convictions; foxes are more cautious, more centrist, more likely to adjust their views, more pragmatic, more prone to self-doubt, more inclined to see complexity and nuance. And it turns out that while foxes don't give great sound-bites, they are far more likely to get things right.

This was the distinction that mattered most among the forecasters, not whether they had expertise. Over all, the foxes did significantly better, both in areas they knew well and in areas they didn't.

Kristoff also observes that pundits are seldom held accountable for being wrong. To the contrary, they get more media attention because their fame is increasing. This provides substance to the ideas that "there is no bad publicity" and "it's better to be wrong than to be irrelevant." It also suggests that what rises to the top even in "serious" media may be froth and not cream. I doubt this means I can get rich betting against famous hedgehogs like, say, Jim Cramer, but it does reinforce my preference for having judgments that affect my life made by foxes instead of hedgehogs. Barack Obama instead of George W. Bush, for example.

Is the latest financial industry bailout plan the only politically available option?

Several commentators think the Public-Private Investment Partnership plan announced yesterday to boost the prices of toxic assets and take them off the hands of troubled banks will do some good but not enough. Brad DeLong suggests the reason:

Why isn’t the administration doing the entire job? My guess is that the Obama administration wants to avoid anything that requires legislative action. The legislative tacticians appear to think that after last week’s furor over the A.I.G. bonuses, doing more would require a congressional coalition that is not there yet. The Geithner plan is one the administration can do on authority it already has.

Loved by corporations, Adam Smith does not reciprocate.

Adam Smith would have been appalled but not surprised by the AIG executive bonus debacle. He understood that the managers of a joint stock company do not have the same interests as the owners and are not likely to watch over other people's money the same way they do their own.

The directors of such companies, however, being the managers rather of other people's money than of their own, it cannot well be expected that they should watch over it with the same anxious vigilance with which the partners in a private copartnery [sic] frequently watch over their own. Like the stewards of a rich man, they are apt to consider attention to small matters as not for their master's honour, and very easily give themselves a dispensation from having it. Negligence and profusion, therefore, must always prevail, more or less, in the management of the affairs of such a company.

Blame the Economists, Not Economics.

I have been such a strong critic of the dominant neoclassical school of economics and free market fundamentalism, that I could perhaps be misunderstood as wanting to replace it with a better paradigm, or even to keep all discussion of economics out of public policy discourse. Not so. I agree with Dani Rodrik's essay with this title that we need more to reform the economists than the economics.

The fault lies not with economics, but with economists. The problem is that economists (and those who listen to them) became over-confident in their preferred models of the moment: markets are efficient, financial innovation transfers risk to those best able to bear it, self-regulation works best, and government intervention is ineffective and harmful.

They forgot that there were many other models that led in radically different directions. Hubris creates blind spots. If anything needs fixing, it is the sociology of the profession. The textbooks at least those used in advanced courses - are fine.

Non-economists tend to think of economics as a discipline that idolizes markets and a narrow concept of (allocative) efficiency. If the only economics course you take is the typical introductory survey, or if you are a journalist asking an economist for a quick opinion on a policy issue, that is indeed what you will encounter. But take a few more economics courses, or spend some time in advanced seminar rooms, and you will get a different picture.

Well, that's a pretty big problem because millions of ordinary citizens and policy makers have been indoctrinated with "the typical introductory survey," and never get to the advanced seminar rooms. And then he goes on to describe the damage done by advanced training in macroeconomics, but regrettably does not call out academic economists for not reforming the way they teach survey courses and advanced macroeconomics.

. . . .

Macroeconomics may be the only applied field within economics in which more training puts greater distance between the specialist and the real world, owing to its reliance on highly unrealistic models that sacrifice relevance to technical rigor. Sadly, in view of today's needs, macroeconomists have made little progress on policy since John Maynard Keynes explained how economies could get stuck in unemployment due to deficient aggregate demand. Some, like Brad DeLong and Paul Krugman, would say that the field has actually regressed.

Economics is really a toolkit with multiple models - each a different, stylized representation of some aspect of reality. One's skill as an economist depends on the ability to pick and choose the right model for the situation.

Economics' richness has not been reflected in public debate because economists have taken far too much license. Instead of presenting menus of options and listing the relevant trade-offs - which is what economics is about - economists have too often conveyed their own social and political preferences. Instead of being analysts, they have been ideologues, favoring one set of social arrangements over others.

Exactly. Every economic model necessarily starts with simplifying assumptions. Instead of always starting with assumptions that seem most likely to be true about the bit of reality being studied--and actually testing assumptions against reality--too many economists seem to use only the assumptions that for philosophical and political reasons they would like to see in some utopian world.

One of the problems may be that economics is not a "profession" like law, medicine, engineering, accounting, etc. "Professionals" are generally held accountable for giving bad advice or putting their own interests ahead of the clients', but it would be pretty hard to sue an economist on either ground. The Harvard Business School and other graduate schools of management are reconsidering whether they have erred by not making management more of a profession, as reported in the New York Times today.

For all of the emphasis on analytical rigor in business schools today, another major recommendation of the foundations' reports from the 1950s — that business become a true profession, with a code of conduct and an ideology about its role in society — got far less traction, said Rakesh Khurana, a professor at Harvard Business School and author of "From Higher Aims to Hired Hands," a historical analysis of business education.

Business schools, he said, never really taught their students that, like doctors and lawyers, they were part of a profession. And in the 1970s, he said, the idea took hold that a company's stock price was the primary barometer of success, which changed the schools' concept of proper management techniques.

Instead of being viewed as long-term economic stewards, he said, managers came to be seen as mainly as the agents of the owners — the shareholders — and responsible for maximizing shareholder wealth.

"A kind of market fundamentalism took hold in business education," Professor Khurana said. "The new logic of shareholder primacy absolved management of any responsibility for anything other than financial results."

All of the wealth ostensibly created in America since 2004 has evaporated.  

The Federal Reserve Board today released its quarterly Z.1 report on the economy. Net worth of American households and non-profit organizations shrank to $51.5 trillion. This is down $12.9 trillion (20%) from the peak of $64.4 trillion in the second quarter of 2007 and is below the $51.9 trillion figure for 2004. Easy come, easy go.

Credit default swaps can create perverse incentives.

The beneficiary of a credit default swap on a company's debt may get a huge payoff from the issuer of the CDS if the covered company defaults on its debt.  It is reported that CDS holders of Lyondellbasell are trying to force it into bankruptcy for just that reason.  The value of CDSs outstanding on the debt of a big company like GM can be much larger that the face amount of the debt because one does not have to own the debt to enter into a CDS.  AIG was a big issuer of CDSs, and it would not be shocking to learn that AIG (and, therefore, US taxpayers) would be one of the biggest losers if GM is not able to avoid bankruptcy.

Obama wearing Reagan’s Teflon suit

President Obama is operating in a way that deprives Congressional Republicans of their best political weapon and preferred and perfected mode of operation—the politics of personal destruction. Because he is nice to them, eloquent in public, hard-working, optimistic, and apparently competent, their attempts to portray him as a villain backfire.  Obama has said he admires the transformations of the Reagan administration, and it seems he's emulating a style that coated Reagan with Teflon and was so instrumental in his effectiveness.

So long as the Teflon holds up, Congressional Republicans have nothing left but strategies that are less effective for them. They are particularly weak on their understanding of and interest in new policies that voters find credible, and their legacy policies are very unpopular. During the 2008 campaign, Republican leaders were saying the GOP brand was broken, but a year ago polls showed that the public hated GOP policies more than their brand.  Since Obama has forced the GOP to park the big attack artillery, they are trying to advance behind a barrage of angry and confused mumbling. 

Not only has the GOP not had a new policy idea since Newt Gingrich left Congress, but its base is being fractured by internal dissention as they attempt to agree on policies to get beyond "tax cuts, deregulation, and every man for himself personal responsibility."  They have evangelicals who are populists and environmentalists and believe in community and helping the needy.  They have business leaders who want the federal government to step in and save them.  They have governors who have serious budget problems and a sense of responsibility.  They have visionaries pointing out that the GOP is doomed demographically if it cannot recruit millions of minorities. And, increasingly, they have insiders and conservative thought leaders who are saying, "It didn't work, and it won't work now; we have to do something different."  It appears they are presently the party of "No" precisely because that is the only thing they can agree on.  That depresses David Brooks and entertains me. 

It seems the national GOP devotes 100% of its thinking to crafting talking points that sound policy-like instead of figuring out how to solve real government-size problems as perceived by voters. Obviously, every party and every politician has to think about the next election, but not thinking at all beyond that is irresponsible and (if there is a God) self-defeating. 

Voters are starting to hold Congressional Republicans accountable and will do so even more as the economy sinks deeper and puts more Independents out of work and Independents realize their 401(k)s are not going to recover soon.  In swing districts, I think GOP candidates railing against "government deficits that burden future generations" will not resonate as much as Democratic calls for dramatic government actions to fix the economy now.  But, the future lies ahead, and Obama and the Dems could easily blow their lead.

The American Dream died in February 1973.  

Since Bob Herbert wrote about Reviving the Dream today, this is a good time to put up the problem-defining graphs from a longer analysis I haven't finished.

The American middle class and working class are essentially the more than 90 million non-supervisory "production workers" who constitute 84% of non-government, non-farm employment. For 26 years, from 1947 to January 1973, their average hourly pre-tax earnings, adjusted for inflation using current methods, grew robustly and steadily at an average annual "real" rate of about 2.2%. At that rate, average purchasing power would double in 33 years. Parents expected their children to have more prosperous lives than their own, and it was happening. It was the Golden Age of the Middle Class. Then, suddenly and permanently, it ended in February 1973.

From 1947 to 1973 real average hourly wage of production workers rose 2.2 percent annually to about $18 per hour in 2009 dollars and then declined to about $16 from the early 1980s to 1997 and stayed below $18 for 35 years until it spiked to just over $18 in late 2008

The proximate cause of the sudden change is obvious. By definition, all of these "production workers" are "employed," and the BLS hourly earnings statistics are gathered from payroll records. Before 1973, employers as a group were giving their existing workforces average annual pay increases that exceeded the inflation rate by 2.2 percentage points. After 1972, they handed out increases that on average only just kept even with inflation.

From 1948 to 1972 production workers got average annual real wage increases averaging 2.35 pct, but from 1973 to 2008 the average annual real wage increase was only 0.01 pct

Meanwhile, the larger economy measured by real GDP per employee had a stagnant decade from 1973 to 1983. But then it took off and averaged 1.14% annual average growth for 25 years. That is modest growth compared to the 2.69% average from 1947 to 1973, but since 5/6 of American workers got a zero share of the post-1983 growth, those who did —presumably management and the owners of capital—did quite nicely.

From 1947 real average hourly earnings of production workers tracked with real GDP per production worker until 1963 when real GDP per production worker began to increase faster and continued to increase faster every year through 2008

So, here's the problem in a nutshell. Average real earnings of the 5/6 of Americans who are production workers cannot go up—and the American Dream cannot be revived—unless employers consistently grant annual wage/salary increases that on average exceed the inflation rate. What changes would motivate and enable large, trend-setting employers to return to giving average annual wage increases—for their existing workforces—that exceed inflation by 1% or 2%?

There are no bad assets. Only misunderstood assets. 

The title comes from Tim Duy via Paul Krugman.  It means the Fed and Treasury still think bad financial assets are underpriced by the market and are trying different subterfuges to prop up the prices by having taxpayers assume the downside risk.  They (and others) think policy makers are delusional about this.

The herd behavior that killed Wall Street (and the rest of us)

Wired has an interesting article explaining some of the mathematical inner workings of The Formula That Killed Wall Street, the "Gaussian cupola function" invented by David X. Li and adopted throughout the financial industry. The article explains why the model used assumptions about mortgage default losses exclusively from a recent ten-year period when default rates were low: The model doesn't input mortgage loss rates at all—it inputs market prices (the wisdom of mobs again) of credit default swaps as surrogates for mortgage loss rates, and CDS trading did not have a long history.

The article discusses who knew what about the limitations and inherent covert risks of the model and who may not have understood but, as Skeptic also reported here, it's clear that the herd instinct overwhelmed reason anyway.

Bankers securitizing mortgages knew that their models were highly sensitive to house-price appreciation. If it ever turned negative on a national scale, a lot of bonds that had been rated triple-A, or risk-free, by copula-powered computer models would blow up. But no one was willing to stop the creation of CDOs, and the big investment banks happily kept on building more, drawing their correlation data from a period when real estate only went up.

"Everyone was pinning their hopes on house prices continuing to rise," says Kai Gilkes of the credit research firm CreditSights, who spent 10 years working at ratings agencies. "When they stopped rising, pretty much everyone was caught on the wrong side, because the sensitivity to house prices was huge. And there was just no getting around it. Why didn't rating agencies build in some cushion for this sensitivity to a house-price-depreciation scenario? Because if they had, they would have never rated a single mortgage-backed CDO."

The only way to keep the herd off dangerous ground, and out of our gardens, is strong regulatory fences.

Thanks to Christine for the heads up.

Paul Volker takes a dim view of "financial innovation."

This is encouraging.  Paul Volker, former chairman of the Federal Reserve Board and current advisor to President Obama, seems to agree with me that there is not much about "financial innovation" that reliably benefits the real economy--or even the financial economy, as it turns out. 

Given the extent of the damage, financial regulations must be improved and enhanced to prevent future debacles, although policy-makers must be cautious not disrupt things further while the turmoil is ongoing.

Volcker, a former chairman of the Federal Reserve famed for breaking the back of inflation in the early 1980s, mocked the argument that "financial innovation," a code word for risky securities, brought any great benefits to society. For most people, he said, the advent of the ATM machine was more crucial than any asset-backed bond.

"There is little correlation between sophistication of a banking system and productivity growth," he said.

Is the best government policy with respect to failing banks more TARP money, nationalization, receivership, bankruptcy, creating sound new banks to compete with them, doing nothing, or something else?  

David Warsh has a good summary of some options being discussed.

How's the US banking crisis going to end? Nouriel Roubini, of New York University, has taken the lead in urging the Swedish solution, namely government receivership: take 'em over, clean 'em up and sell 'em back to the private sector, preferably in pieces. Others, including Chris Whalen, of Institutional Risk Manager, argue that bankruptcy, like Lehman Brothers, is the best procedure. Kill 'em all and let the Bankruptcy Court of the Southern District of New York sort 'em out.

Former Federal Reserve chairman Alan Greenspan and Sen. Sen. Lindsey Graham of South Carolina went out of their way last week to signal to their fellow Republicans that government receivership must be an option. "You should not get hung up on a word [nationalization]," Lindsey told the Financial Times.

Meanwhile, Citibank and Bank of America are fighting tooth and nail to preserve their hegemony. Indeed, Citibank wants more taxpayer money.

How about this instead?  Capitalize half a dozen start-up wholesale banks with government money – call them Hamilton, Jefferson, Franklin, Madison, Adams and Washington. Get them borrowing and lending freely, purchasing assets from legacy banks, and then, equally swiftly, sell them off – privatize them.

Greenspan vs. Greenspan. And the winner is . . . . 

Jon Hilsenrath at the Wall Street Journal:

The Greenspan Doctrine – a view that modern, technologically advanced financial markets are best left to police themselves – has an increasingly vocal detractor. His name is Alan Greenspan.

As Fed chairman, Mr. Greenspan was a frequent opponent of market regulation. Sophisticated markets, he argued, had become increasingly adept at carving up risk themselves and dispersing it widely to investors and financial institutions best suited to manage it.

The retired chairman has had to revise his views. In comments at a New York Economic Club dinner late Tuesday, the retired Fed chairman steered clear of much self-reflection on his role in the credit boom. But he did take a new swipe at the market's self-correcting tendencies and bowed his head to a new period of increased regulation.

"All of the sophisticated mathematics and computer wizardry essentially rested on one central premise: that enlightened self interest of owners and managers of financial institutions would lead them to maintain a sufficient buffer against insolvency by actively monitoring and managing their firms' capital and risk positions," the Fed chairman said. The premise failed in the summer of 2007, he said, leaving him "deeply dismayed."

Self-regulation is still a first-line of defense, Mr. Greenspan said. But after the financial collapse of 2007 and 2008, "I see no alternative to a set of heightened federal regulatory rules of behavior for banks and other financial institutions." He said hoped it would come in the form of tougher capital requirements for banks.

Economic theory in crisis--another view

Financial journalist Anatole Koletsky compares the plight of mainstream economics to historic intellectual disruptions.

In my column last Thursday, I explained how academic economics has been discredited by recent events. It is now time for what historians of science call a “paradigm shift”. If we want to flatter economists, we could compare this revolution needed to the paradigm shift in physics in 1910 after Einstein discovered relativity and Planck launched quantum mechanics. More realistically, economics today is where astronomy was in the 16th century, when Copernicus and Galileo had proved the heliocentric model, but religious orthodoxy and academic vested interests fought ruthlessly to defend the principle that the sun must revolve around the Earth.

He describes the work of Benoit Mandelbrot, George Soros, and several "imperfect knowledge economists" as contradicting fundamental assumptions of the mainstreamers, who rejected or ignored the heterodox ideas that focus attention on the relative high risk of financial crises.

One reason why such fruitful insights have been ignored is the convention adopted by academic economists some 30 years ago that all serious ideas must be expressed in equations, not words. By this weird standard, the intellectual giants of the subject — Adam Smith, Ricardo, Keynes, Hayek — would not now be recognised as serious economists at all.

Free trade does more to redistribute income from labor to capital than it does to increase national income.

A former economics teacher "Wonks Anonymous" does a mea culpa about trade theory:

I believe that there is a fundamental problem with the analysis of free trade that most economists - myself included during my teaching career - present.

When a country has a relative scarcity of labor - like the US today - there are two impacts from trade with a labor abundant world: We see a slight gain in national income and a large redistribution of income from labor to owners of capital.

When faced with this result of trade theory we, as economists, have regularly waved our hands and mumbled something about the "winners" paying off the "losers" out of the overall gains.

Except that we never seem to see the winners paying off the losers.

The problem is that the gain in income is small - it's been years but my best recollection is that the estimated gains from NAFTA did not exceed 1% of GDP. It is a classic example of a "Harberger triangle". At the same time the redistribution is relatively large.

The political motivation for free trade is all about the redistribution and, as economists, we simply enable this redistributionist movement with our arguments about "efficiency"

Avoiding another Great Depression is way less important than winning the next election.

Robert Reich says Congressional Republicans are playing politics with the economic crisis. Rush Limbaugh has said he wants the stimulus package and bank rescues to fail so Republicans can win the next election. Robert Reich:

Republicans don't want their fingerprints on the stimulus bill or the next bank bailout because they plan to make the midterm election of 2010 a national referendum on Barack Obama's handling of the economy. They know that by then the economy will still appear sufficiently weak that they can dub the entire Obama effort a failure -- even if the economy would have been far worse without it, even if the economy is beginning to turn around. They'll say "he wanted more government spending, and we said no, but we didn't have the votes. Elect us and we'll turn the economy around by cutting taxes and getting government out of the private sector."

Obama believes Republicans will eventually embrace bipartisanship. I hope he's right but I fear he's wrong. They want to take back Congress the way Newt Gingrich retook the House (and helped Republicans retake the Senate) in 1994 -- with hellfire and brimstone. Once in control of Congress, they'll be able to block Obama's big inititiaves on health care and the environment, stop any Supreme Court nominees, and set up their own candidate for the White House in 2012.

More bites at the stimulus apple?

Paul Krugman is very worried about the pending economic stimulus package—

Because what's coming out of the current deliberations is really, really inadequate. I've gone through the CBO numbers a bit more carefully; they're projecting a $2.9 trillion shortfall over the next three years. There's just no way $780 billion, much of it used unproductively, will do the job.

Stan Collender explains that neither the regular budget process nor a budget reconciliation bill is subject to filibuster in the Senate and that both are possible in the next few months. He goes on—

My guess is that the Obama administration sees this, sees that it will get credit for even the changed version of the stimulus that is likely to get enacted, understands the political importance of an early legislative victory and, therefore, has decided to take what it can get now and come back for more in other ways in the not too distant future.

And even if that wasn't the orginal strategy, it certainly makes sense now.

George Soros explains "The Crash of 2008" again

George Soros lays out here his narrative of what caused the financial crisis, how it has been mismanaged (especially by not saving Lehman Bros.), and the toxic effects of credit default swaps and collateralized debt obligations. After reading the views of many economists, this is refreshingly practical. The nation and world would be well served if his analysis and advice were heeded at least as much as that of the economists. He says at the end of his piece that he "will next outline the policies that in my opinion the Obama administration ought to pursue, and then assess how the future may play out," but I haven't found that part yet.

To understand the linked article, it is helpful to know that Soros strongly disagrees with the core assumptions of most mainstream economists that prices, in the financial world as well as elsewhere, tend toward equilibrium and that one can safely ignore brief price excursions away from equilibrium. Soros, who has been very active (and very successful) trading in financial markets for decades, says that prices often do not tend toward equilibrium but are inclined to self-reinforcing extremes on the upside and the downside. In his theory of "reflexivity" he says these irrational price swings can affect the actual value of the thing being priced--as for example in a bear run when a bank's rapidly declining stock price may cause loss of confidence in its survival, leading to a real and objective weakening in its ability to operate profitably.

We don’t need a stimulus package—just more tax cuts for the well off—say 36 Republican Senators.

Thirty-six Republican Senators and nobody else voted for an amendment to the economic stimulus bill to strike out the entire contents and substitute nothing but permanent tax reductions benefitting high income individuals and corporations. Republican Senators Snowe and Collins of Maine, Specter of Pennsylvania, and Voinovich of Ohio voted against the amendment, and Senator Gregg of New Hampshire did not vote.

This is the summary of the amendment from the office of Senator DeMint, who offered it:

1) Defuse the 2011 tax bomb: Stop tax increases set to hit the economy in 2011.

  • Permanently repeal the alternative minimum tax once and for all;
  • Permanently keep the capital gains and dividends taxes at 15 percent;
  • Permanently kill the Death Tax for estates under $5 million, and cut the tax rate to 15 percent for those above;
  • Permanently extend the $1,000-per-child tax credit;
  • Permanently repeal the marriage tax penalty;
  • Permanently simplify itemized deductions to include only home mortgage interest and charitable contributions.

2) Long term, broad based tax cuts for American families and businesses.

  • Lower top marginal income rates – the one paid by most of the small businesses that create new jobs – from 35 percent to 25 percent.
  • Simplify the tax code to include only two other brackets, 15 and 10 percent.
  • Lower corporate tax rate as well, from 35 percent to 25 percent. The U.S. corporate tax rate is second highest among all industrialized nations, driving investment and jobs overseas. Lowering this key rate will unlock trillions of dollars to be invested in America instead of abroad.
  • This is not only good economic policy, but a matter of fairness. No American family should be forced to pay the federal government more than 25 percent of the fruits of their hard labor.
