Paul Krugman Wins Economics Nobel
By Catherine Rampell
Paul Krugman, a professor at Princeton University and an Op-Ed columnist for The New York Times, was awarded the Nobel Memorial Prize in Economic Sciences on Monday.
“It’s been an extremely weird day, but weird in a positive way,” Mr. Krugman said in an interview on his way to a Washington meeting for the Group of Thirty, an international body from the public and private sectors that discusses international economics. He said he was mostly “preoccupied with the hassles” of trying to make all his scheduled meetings today and answer a constantly-ringing cell phone.
Mr. Krugman received the award for his work on international trade and economic geography. In particular, the prize committee lauded his work for “having shown the effects of economies of scale on trade patterns and on the location of economic activity.” He has developed models that explain observed patterns of trade between countries, as well as what goods are produced where and why. Traditional trade theory assumes that countries are different and will exchange different kinds of goods with each other; Mr. Krugman’s theories have explained why worldwide trade is dominated by a few countries that are similar to each other, and why some countries might import the same kinds of goods that it exports.

“There was something very beautiful about the old existing trade theory, and its ability to capture the world in a surprisingly simple conceptual framework,” Mr. Krugman said. “And then I realized that some of the new insights coming through in industrial organization could be applied to international trade.”
Mr. Krugman wrote his dissertation, however, on international finance, and credits his late MIT professor Rudiger Dornbusch for pushing him to study international trade.
“I went to visit him one snowy day in early 1978 and described to him what I’d been thinking about,” Mr. Krugman said. “He turned to me and said, ‘You’ve got to write about that.’”
Mr. Krugman has been an Op-Ed columnist at the New York Times since 1999. A collection of his recent columns can be found here.
“For economists, this is a validation but not news. We know what each other have been up to,” Mr. Krugman said. “For readers of the column, maybe they will read a little more carefully when I’m being economistic, or maybe have a little more tolerance when I’m being boring.”
He said that he does not expect his critics to let him off any easier because of his new accolade, though.
“I think we’ve learned this when we see Joe Stiglitz writing,” Mr. Krugman said, referring to the winner of the economics Nobel in 2001. “I haven’t noticed him getting an easy time. People just say, ‘Sure, he’s a great Nobel laureate and he’s very smart, but he still doesn’t know what he’s talking about in this situation.’ I’m sure I’ll get the same thing.”
In 1991 Mr. Krugman received the John Bates Clark medal, a prize given every two years to “that economist under forty who is adjudged to have made a significant contribution to economic knowledge.”
Mr. Krugman follows a number of Clark medal recipients who have gone on to win a Nobel, including Mr. Stiglitz.
“To be absolutely, totally honest I thought this day might come someday, but I was absolutely convinced it wasn’t going to be this day,” Mr. Krugman said. “I know people who live their lives waiting for this call, and it’s not good for the soul. So I put it out of my mind and stopped thinking about it.”
He said he didn’t actually know which day the winner’s name would be released until a colleague told him last week.
Mr. Krugman continues to teach at Princeton. This semester Mr. Krugman is teaching a small graduate-level course on international monetary policy and theory, covering such timely subjects as international liquidity crises. In recent years he has also taught courses on the welfare state and international trade, as well as all-freshman seminars on various economic topics.
Monday’s award is the last of the six prizes and is not one of the original Nobels, but was created in 1968 by the Swedish central bank in Alfred Nobel’s memory. Mr. Krugman was the only winner of the award, which includes a prize of about $1.4 million.
