I was just listening (time-shifted, obviously) to NPR Planet Money's discussion of the recent Nobel Prize in Economics. Aside from the fact that Shiller & Fama won the same prize at the same time for diametrically opposing views (kind of like giving 2 different people prizes for P=NP and P/=NP, simultaneously), the discussion raised some interesting issues about the rationality/irrationality of stock market prices.
