who just won the Nobel Prize for economics:

“What are the effects of free trade and globalization? What are the driving forces behind worldwide urbanization? Paul Krugman has formulated a new theory to answer these questions,” the [Royal Swedish Academy of Sciences] said in its citation.

“He has thereby integrated the previously disparate research fields of international trade and economic geography,” it said.

Although Krugman wasn’t honored for his op-ed pieces in the New York Times, I will always be grateful that he remained unafraid to criticize George Bush and his policies, even at the height of Bush’s popularity in late 2001 and 2002.

In case you weren’t aware, Krugman has a good blog too.
