Today I ran across this talk from Mark Buchanan:

Prediction and its Limits in Socio-Economic Systems

It’s from the International Workshop on Coping with Crises in Complex Socio-Economic Systems that took place in Zurich last May. It provides excellent support for the main point in John’s recent post – that the economy is a complex system, which makes it impossible to predict. Consequently, we need to plan and develop strategy that allows for significant amounts of uncertainty. And one of the best ways to cope with uncertainty is to innovate.

The site also also has talks by Didier Sornette and an all-star cast of econophysicists, if you’re interested in such things (like I am!)
