Economists behaving badly: why individual behaviour is not to blame for the recession

27 05 2009

Bromley illustrationsLast week I attended a meeting with Robert Shiller, a behavioural economist and author of Animal Spirits.  As I have discussed previously, behavioural economics is becoming increasingly influential, particularly as an explanation for the recession and how to get out of it.  Essentially Shiller and others are offering psychological reasons for why people make apparently irrational decisions in the economic sphere.

Shiller’s argument last week boiled down to saying that the recession was caused by lack of confidence, an extension of FD Roosevelt’s proclamation during the 1930s depression that ‘all we have to fear is fear itself”. If you listen to the podcast you will see that in response to  questioning from  Richard Sedley and myself, Shiller is quick to concede that psychology cannot explain everything.

Two reasons why behavioural economics is on the rise

In the current climate of economic and political meltdown however, behavioural economics does not have to be a coherent theory of everything in order to be important. It is becoming increasingly influential because it plays a dual role in the current period of turbulence:

1)  it allows us to feel that it was the mistakes of the greedy bankers, driven by over confidence and corrupted by easy money that caused the recession. In that sense it takes away the necessity to think through what really caused the recession and the underlying political and economic problems that need to be resolved.

2)  if we are irrational beings as Shiller and others suggest, then the State is justified in stepping in to protect us from ourselves. Behavioural economics becomes another reason why the State needs to intervene more, not less, in all aspects of life.

This is why behavioural economics has been taken up by the Obama administration, the British Conservatives and people in New Labour. They are all looking for an explanation, any explanation, so that they can avoid tackling the really hard issues.
