Nationalekonomin i kris

Härom dagen skrev yours truly om  nationalekonomernas ansvar för den ekonomiska krisen här på bloggen. Berkeleyprofessorn J Bradford DeLong skriver insiktsfullt på samma tema i en lysande artikel  på Project Syndicate:

It is the scale of the catastrophe that astonishes me. But what astonishes me even more is the apparent failure of academic economics to take steps to prepare itself for the future. “We need to change our hiring patterns,” I expected to hear economics departments around the world say in the wake of the crisis.

The fact is that we need fewer efficient-markets theorists and more people who work on microstructure, limits to arbitrage, and cognitive biases. We need fewer equilibrium business-cycle theorists and more old-fashioned Keynesians and monetarists. We need more monetary historians and historians of economic thought and fewer model-builders …

Yet that is not what economics departments are saying nowadays.

Perhaps I am missing what is really going on. Perhaps economics departments are reorienting themselves after the Great Recession in a way similar to how they reoriented themselves in a monetarist direction after the inflation of the 1970’s. But if I am missing some big change that is taking place, I would like somebody to show it to me.

Perhaps academic economics departments will lose mindshare and influence to others – from business schools and public-policy programs to political science, psychology, and sociology departments. As university chancellors and students demand relevance and utility, perhaps these colleagues will take over teaching how the economy works and leave academic economists in a rump discipline that merely teaches the theory of logical choice.

Or perhaps economics will remain a discipline that forgets most of what it once knew and allows itself to be continually distracted, confused, and in denial. If that were that to happen, we would all be worse off.
