Why Economists have so little to say about the crisis?

HT to my blog friend Gary for a link to Nobel Economist Jim Buchanan‘s June 19, 2009 talk on “Why Economists have so little to say about the crisis?“

Quoting Wikipedia,

“Buchanan‘s work initiated research on how politicians’ self-interest and non-economic forces affect government economic policy.”

Note: I don’t know how much can or will I agree with Buchanan but it is probably worth a watch.
