'New York Times' columnist Paul Krugman wins Nobel economics prize

Paul Krugman, the Princeton University scholar and New York Times columnist, won the Nobel prize in economics Monday for his analysis of how economies of scale can affect trade patterns and the location of economic activity. Krugman has been a harsh critic of the Bush administration and the Republican Party in The New York Times, where he writes a regular column and has a blog called "Conscience of a Liberal." He has come out forcefully against John McCain during the economic meltdown, saying the Republican candidate is "more frightening now than he was a few weeks ago" and earlier that the GOP has become "the party of stupid." "Krugman is not only a scientist but also an opinion maker," economics prize committee member Tore Ellingsen said. He added that Krugman's analyses tend to back free trade and his research gives no "support for protectionism."
