I just wanted to congratulate Paul Krugman, an economist at Princeton and columnist for the New York Times. Krugman has been awarded this year's Nobel Prize in economics.
Although unfortunately known for his acidic columns assailing the Bush administration, Krugman is also a pathbreaking specialist in international trade, and his popular articles explaining international trade are among the best I've read. The research that led to the award specficially examines how economies of scale affect trade patterns.
I have to admit to being of two minds about Paul Krugman, because there are two Paul Krugmans - the partisan political commentator and the dispassionate trade economist. I'm happy to see the latter recognized.
