Duke University economics professor Dan Ariely joins us once again to talk about his book Predictably Irrational – and to explore the irrationality of our financial system.

The last year has been bad for the stock market…bad for our financial system…bad for the economy as a whole.  But Ariely says it was a good year for Behavioral Economics.  His book is now out with an expanded edition – just in time to make sense of the irrational world we’re currently in.
