Paul R. Krugman

Faced with a need for massive rebuilding in the Gulf Coast, President Bush has refused to estimate how much the effort might cost -- or to raise taxes to pay for it. To discuss the president's economic policy, we speak with columnist Paul Krugman and Stuart Butler of the Heritage Foundation.

Economist and New York Times columnist Paul Krugman. A professor of economics and international affairs at Princeton University, Paul Krugman opposes Bush's Social Security plan, and has written about it in his columns. He's also the author of Fuzzy Math, on the Bush tax cut.

Krugman has collected the last three years of his New York Times op-ed columns in the new book, The Great Unraveling: Losing Our Way in the New Century. In the preface he writes that the book is "a chronicle of the years when it all went wrong again — when the heady optimisim of the late 1990s gave way to renewed gloom. It's also an attempt to explain the how and why: how it was possible for a country with so much going for it to go downhill so fast, and why our leaders made such bad decisions." Krugman teaches at Princeton University.
