Correcting Krugman

Paul Krugman and Robin Wells caricature my recent book Fault Lines in an article in The New York Review of Books. The article, and their criticism, however, do have a lot to say about Krugman’s policy views (for simplicity, I will say “Krugman” and “he” instead of “Krugman and Wells” and “they”), which I have disagreed with in the past. Rather than focus on the innuendo about my motives and beliefs in the review, let me focus on differences of substance. I will return to why I believe Krugman writes the way he does only at the end.

First, Krugman starts with a diatribe on why so many economists are “asking how we got into this mess rather than telling us how to get out of it.”? Krugman apparently believes that his standard response of more stimulus applies, regardless of the reasons why we are in the economic downturn. Yet it is precisely because I think that the policy response to the last crisis contributed to getting us into this one that it is worthwhile examining how we got into this mess, and to resist the unreflective policies that Krugman advocates.

My book emphasizes a number of related fault lines that led to our current predicament. Krugman discusses and dismisses two — the political push for easy housing credit in the United States and overly lax monetary policy in the years 2002-2005 — while favoring a third, the global trade imbalances (which he does not acknowledge are a central theme in my book). I will argue shortly, however, that focusing exclusively on the imbalances as Krugman does, while ignoring why the United States became a deficit country, gives us a grossly incomplete understanding of what happened. Finally, Krugman ignores an important factor I emphasize — the incentives of bankers and their willingness to seek out and take the tail risks that brought the system down.

Let me start with the political push to expand housing credit. I argue that in an attempt to offset the consequences of rising income inequality, politicians on both sides of the aisle pushed easy housing credit through government units like the Federal Housing Administration, and by imposing increasingly rigorous mandates on government-sponsored enterprises such as Fannie Mae and Freddie Mac. Interestingly, Krugman neither disputes my characterization of the incentives of politicians, nor the detailed documentation of government initiatives and mandates in this regard. What he disputes vehemently is whether government policy contributed to the housing bubble, and in particular, whether Fannie and Freddie were partly responsible.

In absolving Fannie and Freddie, Krugman has been consistent over time, though his explanations as to why Fannie and Freddie are not partially to blame have morphed as his errors have been pointed out. First, he argued that Fannie and Freddie could not participate in sub-prime financing. Then he argued that their share of financing was falling in the years mortgage loan quality deteriorated the most.? Now he claims that if they indeed did it (and they did not), it was because of the profit motive and not to fulfill a social objective. Let me offer details.

In a July 14, 2008 op-ed in The New York Times, Krugman explained why Fannie and Freddie were blameless thus:

Partly that’s because regulators, responding to accounting scandals at the companies, placed temporary restraints on both Fannie and Freddie that curtailed their lending just as housing prices were really taking off. Also, they didn’t do any subprime lending, because they can’t: the definition of a subprime loan is precisely a loan that doesn’t meet the requirement, imposed by law, that Fannie and Freddie buy only mortgages issued to borrowers who made substantial down payments and carefully documented their income. So whatever bad incentives the implicit federal guarantee creates have been offset by the fact that Fannie and Freddie were and are tightly regulated with regard to the risks they can take. You could say that the Fannie-Freddie experience shows that regulation works. [emphasis mine]

Critics were quick to point out that Krugman had his facts wrong. As Charles Calomiris, a professor at Columbia University, and Peter Wallison, of the American Enterprise Institute (and member of the Financial Crisis Inquiry Commission), explained, “Here Krugman demonstrates confusion about the law (which did not prohibit subprime lending by the GSEs), misunderstands the regulatory regime under which they operated (which did not have the capacity to control their risk-taking), and mismeasures their actual subprime exposures (which he wrongly states were zero).”

So Krugman shifted his emphasis. In his blog critique of a Financial Times op-ed I wrote in June 2010, Krugman no longer argued that Fannie and Freddie could not buy sub-prime mortgages. Instead, he emphasized the slightly falling share of Fannie and Freddie’s residential mortgage securitizations in the years 2004 to 2006 as the reason they were not responsible. Here again he presents a misleading picture. Not only did Fannie and Freddie purchase whole sub-prime loans that were not securitized (and are thus not counted in its share of securitizations), they also bought substantial amounts of private-label mortgage-backed securities issued by others. When these are taken into account, Fannie and Freddie’s share of the sub-prime market financing did increase even in those years.

“Asset prices and bubbles have momentum. Even if Fannie and Freddie had simply ignited the process, and not fueled it in the go-go years of 2004-2006, they would bear some responsibility.”

Of course, one could question this form of analysis. Asset prices and bubbles have momentum. Even if Fannie and Freddie had simply ignited the process, and not fueled it in the go-go years of 2004-2006, they would bear some responsibility. Krugman never considers this possibility.

In the current review piece, Krugman first quotes the book by Nouriel Roubini and Stephen Mihm: “The huge growth in the subprime market was primarily underwritten not by Fannie Mae and Freddie Mac but by private mortgage lenders like Countrywide. Moreover, the Community Reinvestment Act long predates the housing bubble…. Overblown claims that Fannie Mae and Freddie Mac single-handedly caused the subprime crisis are just plain wrong.”

Clearly, Fannie and Freddie did not originate sub-prime mortgages directly — they are not equipped to do so. But they fuelled the boom by buying or guaranteeing them. Indeed, Countrywide was one of their largest originators of sub-prime mortgages, according to work by Ed Pinto, a former chief credit officer of Fannie Mae, and participated from very early on in Fannie Mae’s drive into affordable housing.

For instance, consider this press release from 1992:

Countrywide Funding Corporation and the Federal National Mortgage Association (Fannie Mae) announced today that they have signed a record commitment to finance $8 billion in home mortgages. Fannie Mae said the agreement is the single largest commitment in its history…The $8 billion agreement includes a previously announced $1.25 billion of a variety of Fannie Mae’s affordable home mortgages, including reduced down payment loans…

“We are delighted to participate in this historic event, and we are particularly proud that a substantial portion of the $8 billion commitment will directly benefit lower income Americans,” said Countrywide President Angelo Mozilo…”We look forward to the rapid fulfillment of this commitment so that Countrywide can sign another record-breaking agreement with Fannie Mae,” Mozilo said.

“Countrywide’s commitment will provide home financing for tens of thousands of home buyers, ranging from lower income Americans buying their first home to middle-income homeowners refinancing their mortgage at today’s lower rates,” said John H. Fulford, senior vice president in charge of Fannie Mae’s Western Regional Office located here.

Of course, as Fannie and Freddie bought the garbage loans that lenders like Countrywide originated, they helped fuel the decline in lending standards. Also, while the Community Reinvestment Act was enacted in 1979, it was the more vigorous enforcement of the provisions of the Act in the early 1990s that gave the government a lever to push its low-income lending objectives, a fact the Department of Housing and Urban Development (HUD) was once proud of (see the HUD press releases below).

Perhaps more interesting is that after citing Roubini and Mihm, Krugman repeats his earlier claim: “As others have pointed out, Fannie and Freddie actually accounted for a sharply reduced share of the home lending market as a whole during the peak years of the bubble.” Now he attributes the inaccurate claim that Fannie and Freddie accounted for a sharply reduced share of the home lending market to nameless “others.” But that is just the prelude to changing his story once again: “To the extent that they did purchase dubious home loans, they were in pursuit of profit, not social objectives—in effect, they were trying to catch up with private lenders.”? In other words, if they did do it (and he denies they did), it was because of the profit motive.

Clearly, everything Fannie and Freddie did was because of the profit motive — after all, they were private corporations. But I don’t know how we can tell without more careful examination how much of the lending they did was to meet the government’s affordable housing mandates or to curry favor with Congress in order to preserve their profitable prime mortgage franchise, and how much was to increase the bottom line immediately.? Perhaps Krugman can tell us how he determined their intent?

Interestingly, before the housing market collapsed, HUD proudly accepted its role in pushing low-income lending through the various levers that Krugman now denies were used. For instance, in 2000 when it announced that it was increasing Fannie and Freddie’s affordable housing goals, it concluded:

Lower-income and minority families have made major gains in access to the mortgage market in the 1990s. A variety of reasons have accounted for these gains, including improved housing affordability, enhanced enforcement of the Community Reinvestment Act, more flexible mortgage underwriting, and stepped-up enforcement of the Fair Housing Act. But most industry observers believe that one factor behind these gains has been the improved performance of Fannie Mae and Freddie Mac under HUD’s affordable lending goals. HUD’s recent increases in the goals for 2001-03 will encourage the GSEs to further step up their support for affordable lending.”

And in 2004, when it announced yet higher goals, it said:

Over the past ten years, there has been a ‘revolution in affordable lending’ that has extended homeownership opportunities to historically underserved households. Fannie Mae and Freddie Mac have been a substantial part of this ‘revolution in affordable lending’. During the mid-to-late 1990s, they added flexibility to their underwriting guidelines, introduced new low-down payment products, and worked to expand the use of automated underwriting in evaluating the creditworthiness of loan applicants. HMDA data suggest that the industry and GSE initiatives are increasing the flow of credit to underserved borrowers. Between 1993 and 2003, conventional loans to low income and minority families increased at much faster rates than loans to upper-income and nonminority families.

IIf the government itself took credit for its then successes in expanding home ownership, why is Krugman not willing to accept its contribution to the subsequent bust as too many lower middle-class families ended up in homes they could not afford? I agree there is room for legitimate differences of opinion on the quality of data, and the extent of government responsibility, but to argue that the government had no role in directing credit, or in the subsequent bust, is simply ideological myopia.

Let me move on to Krugman’s second criticism of my diagnosis of the crisis. He argues that the Fed’s very accommodative monetary policy over the period 2003 to 2005 was also not responsible for the crisis. Here Krugman is characteristically dismissive of alternative views. In his review, he says that there were good reasons for the Fed to keep rates low given the high unemployment rate. Although this may be a justification for the Fed’s policy (as I argue in my book, it was precisely because the Fed was focused on a stubbornly high unemployment rate that it took its eye off the irrational exuberance building in housing markets and the financial sector), it in no way validates the claim that the policy did not contribute to the manic lending or housing bubble.

A second argument that Krugman makes is that Europe too had bubbles and the European Central Bank was less aggressive than the Federal Reserve, so monetary policy could not be responsible. It is true that the European Central Bank was less aggressive, but only slightly so: It brought its key refinancing rate down to only 2 percent, while the Fed brought the Fed Funds rate down to 1 percent. Clearly, both rates were low by historical standards. More important, what Krugman does not point out is that different Euro-area economies had differing inflation rates, so the real monetary policy rate was substantially different across the Euro area despite a common nominal policy rate. Countries that had strongly negative real policy rates — Ireland and Spain are primary exhibits — had a housing boom and bust, while countries like Germany with low inflation, and therefore higher real policy rates, did not. Indeed, a working paper by two ECB economists, Angela Maddaloni and José-Luis Peydró, indicates that the ultra-low rates enforced by both the ECB and the Fed at this time had a strong causal effect in relaxing banks’ commercial, mortgage, and retail lending standards over this period.

I admit that there is much less consensus on whether the Fed helped create the housing bubble and the banking crisis than on whether Fannie and Freddie were involved. Ben Bernanke, a monetary economist of the highest caliber, denies it, while John Taylor, an equally respected monetary economist insists on it. Some Fed studies accept responsibility while others deny it. Krugman, of course, has an interest in defending the Fed and criticizing alternative viewpoints. He himself advocated the policies the Fed followed, and in fact, was critical of the Fed raising rates even when it belatedly did so in 2004. Then, as he does now, Krugman emphasized the dangers from a Japanese-style deflation, as well as the slow progress in bringing back jobs. Then, as he does now, he advocated more stimulus. Then, as he does now, Krugman ignored the longer term adverse consequences of the policies he advocated.

“The United States did not have to run a large trade deficit and absorb the capital inflows – the claim that it had to sounds very much like that of the over-indulgent and over-indebted rake who blames his creditors for being willing to finance him. “

Finally, if he denies a role for government housing policies, or for monetary policy, or even for warped banker incentives, then what does Krugman attribute the crisis to? His answer is over-saving foreigners. Put simply, trade-surplus countries like Germany and China had to reinvest their financial surpluses in the United States, pushing down long-term interest rates in the process, and igniting a housing bubble that eventually burst and led to the financial panic. But this is only a partial explanation, as I argue in my book. The United States did not have to run a large trade deficit and absorb the capital inflows – the claim that it had to sounds very much like that of the over-indulgent and over-indebted rake who blames his creditors for being willing to finance him. The United States’s policies encouraged over-consumption and over-borrowing, and unless we understand where these policies came from, we have no hope of addressing the causes of this crisis.? Unfortunately, these are the policies that Krugman wants to push again. This is precisely why we have to understand the history of how we got here, and why Krugman wants nothing to do with that enterprise.

There is also a matter of detail suggesting why we cannot only blame the foreigners. The housing bubble, as Monika Piazzesi and Martin Schneider of Stanford University have argued, was focused in the lower income segments of the market, unlike in the typical U.S. housing boom. Why did foreign money gravitate to the low income segment of the housing market? Why did past episodes when the U.S. ran large current account deficits not result in similar housing booms and busts?? Could the explanation lie in U.S. policies?

My book suggests that many — bankers, regulators, governments, households, and economists among others — share the blame for the crisis. Because there are so many, the blame game is not useful. Let us try and understand what happened in order to avoid repeating it. I detail the hard choices we face in the book. While it is important to alleviate the miserable conditions of the long-term unemployed today, we also need to offer them incentives and a pathway to building the skills that are required by the jobs that are being created. Simplistic mantras like “more stimulus” are the surest way to distract us from policies that generate sustainable growth.

Finally, a note on method. Perhaps Krugman believes that by labeling other economists as politically extreme, he can undercut their credibility. In criticizing my argument that politicians pushed easy housing credit in the years leading up to the crisis, he writes,? “Although Rajan is careful not to name names and attributes the blame to generic ‘politicians,’ it is clear that Democrats are largely to blame in his worldview.” Yet if he read the book carefully, he would have seen that I do name names, arguing both President Clinton with his “Affordable Housing Mandate” (see Fault Lines, page 35), as well as President Bush with his attempt to foster an “Ownership Society” (see Fault Lines, page 37) pushed very hard to expand housing credit to the less well-off. Indeed, I do not fault the intent of that policy, only the unintended consequences of its execution. My criticism is bipartisan throughout the book, including of the fiscal policies followed by successive administrations. Errors of this kind by an economist of Krugman’s stature are disappointing.


An excellent review of economic history as it relates to the created housing bubble.


"errors of this kind... are disappointing" - but utterly typical for Krugman!

If one were to read only Krugman's commentary, one would learn that everyone who disagrees with Krugman is a fraud, politically motivated, misleading, cynical, etc.

This in itself harms Krugman's credibility.

Never, since the Bush years, will one read from Krugman the sort of balanced sentences from Rajan above, emphasizing multiple possibilities, multiple actors, multiple competing explanations...

In Krugman's world, there are only white hats and black hats - full stop. Just pathetic.


Wow dude. That was long winded.

The Housing Boom was perpetuated by many actors, politics included because in the 2000's it was literally all we had going for us. I remember those "heady" days where the daily market report would state how all sorts of things were weak, but "housing and construction remain strong." I was puzzled for how much longer things could keep going bases solely on housing appreciation and construction.

It was the classic holding the wolf by the ears situation. Had anyone in government tried to put the brakes on the housing bubble it would have caused an instant recession because it was ALL we had keeping people employed. By not doing anything the situation was sure to get worse, but to those in government at the time the consequence of being kicked out of office was the same no matter how bad the resulting collapse would be so they chose to double down and hang on as long as they could.


Paul Krugman may have won a Nobel prize, but he is just as fallible as the rest of us humans. Perhaps more so, if the Nobel lead to over-confidence and a failure to consider other points of view.


I have never read a better takedown of Krugman. Bravo, sir.


Yet again you make several straw man arguments. Notably:

"In his review, he says that there were good reasons for the Fed to keep rates low given the high unemployment rate. Although this may be a justification for the Fed's policy [...], it in no way validates the claim that the policy did not contribute to the manic lending or housing bubble."

If you had read his review carefully, you'd see that Krugman plainly did not make this point to claim that the the policy didn't contribute to the bubble. Rather, he states that even if it did contribute, he still thinks it was the right policy.

Next you say:

"A second argument that Krugman makes is that Europe too had bubbles and the European Central Bank was less aggressive than the Federal Reserve, so monetary policy could not be responsible."

Again, close reading makes it clear that Krugman simply doesn't make this argument:

"The fact that the housing bubble was a North Atlantic rather than purely American phenomenon also makes it hard to place primary blame for that bubble on interest rate policy."

I can only assume that you deliberately craft these straw men, since it would be too ironic if you just failed to carefully read his review.



i don't buy much of this rebuttal- Krugman deflects blame from F + F to highlight the much more systemic risk imposed on the system by private subprime securitzation expansion- i think Krugman's point was that while F + F were pulling out of the subprime market, the too-big-to-not-bailout players were expanding their holdings- and Krugman has been crystal clear in blaming the Fed for negligence- he has openly critiqued Greenspan and Bernanke for failure to prick the bubble- and using Germany as an example here is ironic- the fact is that Germany's economy was insulated from the great recession becuse of their trade surplus, and their higher rate of stimulus has accelerated their recovery- in the end, Rajan should follow his own advice: "let us try and understand what happened in order to avoid repeating it"- ok, so pick up a history book and ull figure out that this is all precisely what happened in the great depression- Glass-Steagall was enacted to prevent banking corruption from reappearing, and there was a massive government stimulus called world war II which recovered the us economy- it is the negligence of our policy makers who, as here, pretend not to know that this has all already happened, through refusing to follow the correct policy out of this recession


Ed Mroz

This column inadvertently supports a major complaint that Mr. Krugman and others make--nothing is said about what to do now in this generally rich country where one of seven lives in poverty and long-term unemployment is the highest in decades.

I haven't heard anyone suggest that the way out of the current US economic predicament is to return to aggressive sub-prime mortgage lending. Yet over half (33 out of 57 column inches on my screen) of this article is about whether Fannie and Freddie contributed to that debacle.

Mr. Krugman at least has made concrete suggestions (however unlikely to be adopted) about ways to get us out of our present economic predicament.

I appreciate the importance of understanding what didn't work in the past. But what is the argument here against Mr. Krugman's prescriptions for the future, other than the somewhat ad-hominem arguments that he might have been wrong about some matters in the past and that he "caricatured" Mr. Rajan's book?

More important, what specifically does Mr. Rajan propose that we do now instead? "Building the skills that are required by the jobs that are being created" is certainly important, and I would guess that Mr. Krugman agrees. But that takes time and long-term investment, while the pain has already been substantial for years (at least outside the worlds of dueling globe-hopping tenured economists) and shows little sign of abating soon.

So what is to be done?

Whenever I've been offered THE reason for the recession, I've always rejected it out of hand. I suspected (1) the reason had to be plural, (2) the reasons crossed political boundaries, (3) the reasons were a mix of public and private excesses or mistakes, and (4) the reasons would not be evident for many years-- it takes time to ferret, vett, and contextualize complex faults.

In other words, if the explanation doesn't mention monetary policy, housing policy, the Basel capital requirements, compensation structure and other items, it probably doesn't hold water.

It appears that professor Rajan and his book have established a bridgehead into that reasonable explanation world.


good god, just read krugman more often. you will find he is just a bombastic, name-caller. Actually read the piece on him in the New Yorker of a few months ago. you'll get a real "appreciation" of the man.


The largest government failure wasn't the banks and GSEs buying the trash Wall Street was creating or the Fed lowering rates, but their failure to regulate lending despite their explicit duty to establish money and regulate its value. That was more due to market fundamentalism among regulators than even political pressure, a misguided ideology at work that they used to abrogate their responsibilities, and that everyone else used to for the same purpose.

Robert Evans

At the beginning and at the end of the article we are told to avoid unreflective policeis of simple stimulus. Yet no alternative policices were suggested. One wonders why.

The comment about teaching the unemployed the skills they need for the new jobs reminds me of the "structural unemployment "discussions some 50 years ago. The structural side turned out to be wrong (me included) and I suspect it will again be wrong.

Manuel Vasquez

Ed Mroz-

How do you know what to fix, if you don't know what caused the break-down? If your car seizes up, do you want a mechanic who looks for what caused the break-down, or one who says, "let's just replace the whole engine, the upholstery and the oil filter"?


Here we go again, blaming the government for creating the crisis. While it may have been a facilitator, no one held fire to banker's feet forcing them to make loans they KNEW could never be repaid. There was no government mandate for the relentless uptick in prices, well beyond the realm of affordability, which were fraudulently ratcheted up by entities looking to profit by intimidation of appraisers and blacklisting banks not complicit with schemes; nor was there a requirement for the development of predatory mortgages. Also a colossal breakdown of financial responsibility, where the financial hot potato was passed on down the line, no one ultimately having responsibility for toxic /instruments other than homeowners who lost their houses; the proliferation of obfuscatory financial instruments which were allowed to multiply through lack of regulation and oversight (absence of government), not helped by lack of accounting standards, the development of which accounting lobbies eschew, absolutely in contravention to their stated purpose...


Michael Casp

It's about time this blog started taking it to that hack, Paul Krugman.

His mistaken idea that he is the only economist in the world who's opinion matters has grown awfully tiresome over the years.

I'm glad to see my favorite blog standing up for intellectual integrity. Better late than never.


?Bravo!... but as you know american crisis has neither causes nor responsibles. Politics doesn't like...



Intellectually, personality-wise, and physically, Paul Krugman is virtually indistinguishable from the drug-addled, mentally troubled, alcoholic panhandlers who rudely accost commuters around Port Authority and Penn Station.

The only difference I can see is that he's somehow managed to convince the NYT, Princeton University and the Nobel Prize Committee that what is so tragic in those panhandlers is somehow admirable in him.


I'm always delighted by long-winded, partially ad-hominemed and poorly reasoned arguments against Krugman.

He has really touched a nerve, hasn't he? Why, it is almost as if one side is paid to obfuscate in the service of wealth, and the other is calling it as it is. It would be fun watching Greenspan buckle his world-view in front of Congress and the world, if the supply siders didn't do such a good job of destroying my savings, my neighbors savings, etc.

Count down to 'yeah but he worked for Enron a decade before it became a criminal enterprise in 3,
2, 1...

Biff Bigman

Ah yes, a dignified way of saying, "Jane, you ignorant slut."

It would have made a rather lengthy Saturday Night Live skit, but it's an enjoyable read here. One wonders what criteria are used to hand out Nobel Prizes these days. I'm thinking a dart board or Tarot cards may be involved.
