Why So Little Self-Recrimination Among Economists?

[from:

Why is it that economics is a Teflon discipline, seemingly unable to
admit or recognize its errors?

Economic policies in the US and most advanced economies are to a
significant degree devised by economists. They also serve as policy
advocates, and are regularly quoted in the business and political
media and contribute regularly to op-ed pages.

We have just witnessed them make a massive failure in diagnosis.
Despite the fact that there was rampant evidence of trouble on various
fronts – a housing bubble in many countries (the Economist had a major
story on it in June 2005 and as readers well know, prices rose at an
accelerating pace), rising levels of consumer debt, stagnant average
worker wages, lack of corporate investment, a gaping US trade deficit,
insanely low spreads for risky credits – the authorities took the
"everything is for the best in this best of all possible worlds"
posture until the wheels started coming off. And even when they did,
the vast majority were constitutionally unable to call its trajectory.

Now of course, a lonely few did sound alarms. Nouriel Roubini and
Robert Shiller both saw the danger of the housing/asset bubble; Jim
Hamilton at the 2007 Jackson Hole conference said that the markets
would test the implicit government guarantee of Fannie and Freddie;
Henry Kaufman warned how consumer and companies were confusing access
to credit (which could be cut off) with liquidity, and about how
technology would amplify a financial crisis. Other names no doubt
belong on this list, but the bigger point is that these warnings were
often ignored.

Shiller has offered a not-very-convincing defense, claiming that
economists were subject to "groupthink" and no one wanted to stick his
neck out. That seems peculiar given that many prominent policy
influencers are tenured. They would seem to have greater freedom than
people in any other field to speak their mind. And one would imagine
that being early to identify new developments or structural shifts
would enhance one's professional standing.

But if a doctor repeatedly deemed patients to be healthy that were
soon found to have Stage Four cancer that was at least six years in
the making, the doctor would be a likely candidate for a malpractice
suit. Yet we have heard nary a peep about the almost willful blindness
of economists to the crisis-in-its-making, with the result that their
central role in policy development remains beyond question.

Perhaps the conundrum results from the very fact that they are too
close to the seat of power. Messengers that bear unpleasant news are
generally not well received. And a government that wanted to engage in
wishful, risky policies would want a document trail that said these
moves were reasonable. "Whocouldanode" becomes a defense.

But how economists may be compromised by their policy role is way
beyond the scope of a post. To return to the matter at hand: there
appears to be an extraordinary lack of introspection within the
discipline despite having presided over a Katrina-like failure. Jeff
Madrik tells us:

>At the annual meeting of American Economists, most everyone refused to admit 
>their failures to prepare or warn about the second worst crisis of the 
>century. ...[already posted on pen-l] <

Madrik goes on in the balance of his piece to offer a list of things
economists got wrong. Unfortunately, it's off the mark in that he
contends that economists (in effect) had unified beliefs on a lot of
fronts. It's a bit more accurate to say that there was a policy
consensus, and anyone who deviated from the major elements had a
bloody hard time getting a hearing (Dean Baker regularly points out
that the New York Times and Washington Post still keep quoting
economists who got the crisis wrong). The particulars on his list need
some work too, but at least it's a start (reader comments and
improvements on it would be very much appreciated).

But Madrik does seem spot on about the lack of needed navel-gazing. I
looked at the AEA schedule and did not see anything that questioned
existing paradigms. And one paper that did was released recently, "The
Crisis of 2008: Structural Lessons for and from Economics," fell so
far short of asking tough questions that it proves Madrik's point. The
analysis is shallow and profession serving. And that is not to say the
author, Daron Acemoglu, is writing in bad faith, but to indicate how
deeply inculcated economists are.

For instance, one of the three (only three?) ways in which he says
economists took too much comfort in the Great Moderation;

>The seeds of the crisis were sown in the Great Moderation... Everyone who 
>patted themselves or others on the back during that time was really missing 
>the point... The same interconnections that reduced the effects of small 
>shocks created vulnerability to massive system-wide domino effects. No one saw 
>this clearly.<

Huh? The problems with the Great Moderation were far more deeply
rooted than this depiction suggests. Acemoglu's take is that the
economy became more susceptible to shocks (that is, absent the bad
luck of a shock, things could have continued merrily along). Thomas
Palley argues, persuasively, that it was destined to come a cropper:

>The raised standing of central bankers rests on a phenomenon that economists 
>have termed the "Great Moderation." This phenomenon refers to the smoothing of 
>the business cycle over the last two decades, during which expansions have 
>become longer, recessions shorter, and inflation has fallen.

>Many economists attribute this smoothing to improved monetary policy by 
>central banks, and hence the boom in central banker reputations. This 
>explanation is popular with economists since it implicitly applauds the 
>economics profession by attributing improved policy to advances in economics 
>and increased influence of economists within central banks. For instance, the 
>Fed's Chairman is a former academic economist, as are many of the Fed's board 
>of governors and many Presidents of the regional Federal Reserve banks.

>That said, there are other less celebratory accounts of the Great Moderation 
>that view it as a transitional phenomenon, and one that has also come at a 
>high cost. One reason for the changed business cycle is retreat from policy 
>commitment to full employment. The great Polish economist Michal Kalecki 
>observed that full employment would likely cause inflation because job 
>security would prompt workers to demand higher wages. That is what happened in 
>the 1960s and 1970s. However, rather than solving this political problem, 
>economic policy retreated from full employment and assisted in the 
>evisceration of unions. That lowered inflation, but it came at the high cost 
>of two decades of wage stagnation and a rupturing of the link between wage and 
>productivity growth.

>Disinflation also lowered interest rates, particularly during downturns. This 
>contributed to successive waves of mortgage refinancing and also reduced cash 
>outflows on new mortgages. That improved household finances and supported 
>consumer spending, thereby keeping recessions short and shallow.

>With regard to lengthened economic expansions, the great moderation has been 
>driven by asset price inflation and financial innovation, which have financed 
>consumer spending. Higher asset prices have provided collateral to borrow 
>against, while financial innovation has increased the volume and ease of 
>access to credit. Together, that created a dynamic in which rising asset 
>prices have supported increased debt-financed spending, thereby making for 
>longer expansions. This dynamic is exemplified by the housing bubble of the 
>last eight years.

>The important implication is that the Great Moderation is the result of a 
>retreat from full employment combined with the transitional factors of 
>disinflation, asset price inflation, and increased consumer borrowing. Those 
>factors now appear exhausted. Further disinflation will produce disruptive 
>deflation.<

Palley wrote this in April 2008, although he had touched on some of
these issues earlier. Did this view reach a wide audience? No.
Understanding why might help us understand better why the economics
profession went astray.

Acemoglu's paper had a couple of other eye-popping items: Even though
he gives lip service to the idea that the economics was unduly infused
with ideas from Ayn Rand, he then backtracks:

>On the contrary, the recognition that markets live on foundations laid by 
>institutions — that free markets are not the same as unregulated markets — 
>enriches both theory and its practice.<

"Free markets" is Newspeak, and the sooner we collectively start to
object to the use of that phrase, the better. Because it is imprecise
and undefined, advocates can use it to mean different things in
different contexts. I cannot take any economist seriously who uses
"free markets" in anything more rigorous than a newspaper column (and
even there it would annoy me). It has NO place in an academic paper
(save perhaps on the evolution of the concept).

We also have this:

>A deep and important contribution of the discipline of economics is the 
>insight that greed is neither good nor bad in the abstract.<

This reveals that Acemoglu has been corrupted by Rand more than he
seems willing to recognize. No one would have dared write anything
like that even as recently as ten years ago. Let us consider the
definition of greed, from Merriam Webster:

>a selfish and excessive desire for more of something (as money) than is needed<

Greed is different than, say, ambition. "Greed is good" was famously
attributed to criminal Ivan Boesky, and later film felon Gordon Gekko.

Put more bluntly, greed is the id without restraint. Psychiatrists,
social workers, policemen, and parents all know that unchecked,
conscienceless desire is not a good thing. Acemoglu calls for external
checks ('the right incentive and reward structures"), when the record
of the last 20 years is that a neutral to positive view of greed
allows for ambitious actors to increasingly bend the rules and amass
power. The benefits are concentrated, and the costs often sufficiently
diffuse as to provide for insufficient incentives (or even means) for
checking such behavior. Like it or not, there is a role for social
values, as nineteenth century that may sound. The costs of providing a
sufficiently elaborate superstructure of rules and restrictions is far
more costly than having a solid baseline of social norms. But our
collective standards have fallen so far I am not sure we can reach a
better equilibrium there.
