Getting up to Speed on the Financial Crisis: A One-Weekend-Reader's Guide

Abstract

All economists should be conversant with “what happened?” during the financial crisis of 2007-2009. We select and summarize 16 documents, including academic papers and reports from regulatory and international agencies. This reading list covers the key facts and mechanisms in the build-up of risk, the panics in short-term-debt markets, the policy reactions, and the real effects of the financial crisis.

First Review from Triple Crisis (Matias Vernengo)

Gary Gorton and Andrew Metrick have just produced a survey on the vast literature on what happened during the last financial crisis (and to a lesser extent why it did) titled “Getting Up To Speed on the Financial Crisis,” to be published by the Journal of Economic Literature. They used only 16 documents, between papers from ‘top journals,’ reports and speeches and congressional testimonies. It must be noted that the objective of the review is to provide “a one-weekend-reader’s guide” to the crisis.

The biggest problem with their paper is not the limited number of documents reviewed, which seem to be fairly representative of conventional views on the financial crisis, but the limitations of what the mainstream of the profession knows about the crisis, and worse, what the profession clearly does not know it does not know, the unknown unknowns, so to speak. And that is why ignoring heterodox and progressive contributions has been very harmful for the profession. I will use three of their cited documents as an example of what I mean.

 Take, for example, Ben Bernanke’s (2005) speech, in which he argues that a global savings glut has caused the global imbalances, i.e. the large US current account deficits. Lack of savings in the US was seen by him as a problem. Even if we go beyond the questions of causality, and Bernanke’s implicit acceptance of Say’s Law, and whether savings are actually relevant for growth, it must be noted that the problem of the US was not low savings, but the fact that private spending was based on unsustainable debt accumulation, a point raised by, for example, Wynne Godley long ago. Bernanke wanted fiscal adjustment, and had nothing to say about stagnating wages being the reason why families got indebted. Understanding effective demand, Godley (1999, p. 1) argued that if “private expenditure at some stage reverts to its normal relationship with income, there will be, given present fiscal plans, a severe and unusually protracted recession with a large rise in unemployment.” In other words, without debt a fall in private spending, caused in this case by the pricking of the dot-com bubble, not compensated by big fiscal deficits (he thought those would be necessary), would lead to where we ended, a big recession.

Of course the housing bubble prolonged the debt-led expansion. On the housing bubble the authors of the review refer to Case and Shiller (subscription required), which they call “a remarkably prescient paper.” If one goes to the paper, what Case and Shiller actually argue is that: “judging from the historical record, a nationwide drop in real housing prices is unlikely, and the drops in different cities are not likely to be synchronous: some will probably not occur for a number of years. Such a lack of synchrony would blunt the impact on the aggregate economy of the bursting of housing bubbles” (2003: p. 342). In other words, no there was no bubble, fundamentals could explain the home price increases observed in most of the United States and if prices fell a collapse of the economy could be avoided. Prescient indeed! They ignore the contributions by Dean Baker, which were truly prescient. For example, he already complained back in 2003 (same year of Case and Shiller) that “the vast majority of economic analysts have failed to recognize the [current] housing bubble.”

Finally, Gorton and Metrick (2012, p. 2) suggest that the main empirical fact about financial crisis comes from the work by Reinhart and Rogoff (2011), which shows that there is a “strong association between accelerations in economy-wide leverage and subsequent banking crises.” That is hardly new, and by no means the main empirical fact about this crisis. Worse, in a previous paper, Reinhart and Rogoff (2010) argued that public-debt-to-GDP ratio of an economy could not exceed 90% without negatively affecting growth rates, a proposition that suggests that public, not private debt is dangerous, which is the opposite of what they should have learned. Nersisyan and Wray (2010) completely debunked that proposition and found that out of 216 observations, only five revealed public-debt-to-GDP ratios that exceeded 90 per cent. Further, Reinhart and Rogoff (2011) have nothing to say on financial deregulation as one of the causes of the crisis, or the effects of worsening income distribution and wage stagnation in promoting economy-wide leverage, particularly in the private sector. For that, one would be better served by Barba and Pivetti (2009; subscription required).

So if you read all the 16 documents suggested by Gorton and Metrick you may truly be up to speed with what the mainstream of the profession knows about the financial crisis. But the orthodoxy of the profession is still lagging behind and has a lot of catching up to do with heterodox and progressive economists. They might at least acknowledge it, and try to incorporate heterodox insights (if not their methods) if they want the profession to remain relevant.

 

Second Review from Triple Crisis (Edward Barbier)

The survey by Gary Gorton and Andrew Metrick on what happened during the 2008-9 financial crisis, “Getting Up To Speed on the Financial Crisis,” to be published by the Journal of Economic Literature, focuses on an important cause of this crisis: global imbalances in the world economy.  As Gorton and Metrick suggest, such imbalances include the “institutional cash pools” caused by sovereign wealth funds and the “global savings glut”.

While the United States has been amassing large current account deficits, China, Japan, other Asian emerging market economies and some oil exporters have been generating trade surpluses.  Similar structural imbalances were occurring within major regional economies, such as the European Union, where the large current account surpluses of France and Germany were offset by deficits in Ireland, Greece, Portugal, Spain and the United Kingdom.  The result was that economies with chronic trade deficits were receiving large and sustained capital inflows from surplus economies seeking new asset investments. These massive credit flows precipitated the bubble and subsequent bust in financial markets, and the persistence of such global imbalances continues to add to the uncertainty and instability of the world economy.

Understanding how the global imbalances caused the financial crisis and subsequent recession is important. But addressing these imbalances in the world economy will need a much more profound change in global economic development.

In a paper published in World Economics in November 2010, Green Stimulus, Green Recovery and Global Imbalances”, I argued that a global green recovery strategy of reducing carbon dependency and improving energy security may therefore help to control both the large current account deficits incurred by major oil-importing economies, such as the United States, and to reduce the trade surpluses of fossil fuel exporting economies.  To the extent that global green recovery can help to reduce both the volume of fossil fuel imports into deficit economies such as the United States, and help stem the rise in world prices, then it may help alleviate global imbalances by curbing current account deficits and surpluses in oil exporting economies.

Although reducing the chronic trade surpluses in Asian and other emerging market economies is more complex, a necessary step will be to rebalance the pattern of economic growth in these economies to absorb more of their savings domestically. Expanding clean energy investments and adopting low carbon technologies could be key to this strategy.  Policies to target and develop clean energy, sustainable transport and other green sectors as new growth poles in emerging market and developing economies should foster production of modern tradable goods and services to meet expanding domestic demand. Increased spending on safety net programs, education, sanitization and improved water supplies, health care and other government insurance mechanisms could help reduce the precautionary motives for saving by households in developing countries.  The result would be a multiplier effect through lowering economy-wide excess saving while promoting higher household consumption.

It is important to get up to speed on how we got into the current economic crisis, but it is also essential that we do not rush into “business as usual” solutions that will fail to prevent future crises from occurring.
