Working Papers

Eugene Fama, one of the founders of the so-called “Efficient Markets Hypothesis” (EMH), articulated early on the basic narrative that underpins it: “competition… among the many [rational] intelligent participants [would result in an] efficient market at any point in time [in which] the actual price of a security will be a good estimate of its intrinsic value” (Fama, 1965, p. 56).

The current economic and financial crisis, and it is both, has already imposed great costs on the global economy. Nor is there any guarantee that we have seen the worst and that recovery is now assured.

Economic theory has modeled itself on theoretical physics. It has sought to establish timelessly valid laws that govern economic behavior and can be used reversibly both to explain and to predict events.

The world economy in 2008-2009 has passed through the most severe economic downturn since World War II. This global recession was preceded by the collapse of some of the largest financial institutions in the world.

This is not intended to be a purely historical paper. I am interested in the light the Keynesian and Hayekian interpretations of the Great Depression throw on the causes of the Great Recession of 2007-9 and in the policy relevance of the two positions to the management of today’s globalizing economy.
