Joseph Stiglitz won the 2001 Nobel Prize for his work on the effect of information asymmetries on markets. He used that lens to talk about the current sub-prime mess and its effects globally.

Very illuminating. And quite entertaining as well – with some amusing and pointed digs at Greenspan (considering that Stiglitz was the Chairman of the Council of Economic Advisers during the Clinton years, you know how he leans).

These Nobel Laureates are sharp cookies.
