Eugene Fama — economics of denial

16 Oct, 2013 at 08:06 | Posted in Economics | 2 Comments

The so-called “Chicago School” has mounted a robust defense of its rational expectations-based approach, rejecting the notion that a rethink is required. The Nobel laureate economist Robert Lucas has argued that the crisis was not predicted because economic theory predicts that such events cannot be predicted. So all is well …

We should not focus attention exclusively on economists, however.
Arguably the elements of the conventional intellectual toolkit found most wanting are the capital asset pricing model and its close cousin, the efficient-market hypothesis. Yet their protagonists see no problems to address.

On the contrary, the University of Chicago’s Eugene Fama has described the notion that finance theory was at fault as “a fantasy,” and argues that “financial markets and financial institutions were casualties rather than causes of the recession.” And the efficient-market hypothesis that he championed cannot be blamed, because “most investing is done by active managers who don’t believe that markets are efficient.”

This amounts to what we might call an “irrelevance” defense: Finance theorists cannot be held responsible, since no one in the real world pays attention to them!

  1. “So you are saying the recession predated August 2007″, to which Fama replied:

    Yeah. It had to, to be showing up among people who had mortgages.
