Congratulations to Paul Krugman

Huge congratulations to Princeton economist — and part-time NY Times columnist — Paul Krugman for winning the Nobel in Economics today.

Mr. Krugman was the lone winner of the 10 million kronor ($1.4 million) award and the latest in a string of American researchers to be honored. The Royal Swedish Academy of Sciences praised Mr. Krugman for formulating a new theory to answer questions about free trade.

"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 academy said in its citation. "He has thereby integrated the previously disparate research fields of international trade and economic geography," it said.
