Paul Krugman - Academic Career

Academic Career

Krugman earned his B.A. in economics from Yale University summa cum laude in 1974 and his PhD from the Massachusetts Institute of Technology (MIT) in 1977. While at MIT he was part of a small group of MIT students sent to work for the Central Bank of Portugal for three months in the summer of 1976, in the chaotic aftermath of the Carnation Revolution. Krugman later praised his PhD thesis advisor, Rudiger Dornbusch, as "one of the great economics teachers of all time", and that he "had the knack of inspiring students to pick up his enthusiasm and technique, but find their own paths".

In 1978, Krugman presented a number of ideas to Dornbusch, who flagged as interesting the idea of a monopolistically competitive trade model. Encouraged, Krugman worked on it, and later wrote, " knew within a few hours that I had the key to my whole career in hand". In that same year, Krugman wrote The Theory of Interstellar Trade, a tongue-in-cheek essay on computing interest rates on goods in transit near the speed of light. He says he wrote it to cheer himself up when he was "an oppressed assistant professor".

Krugman joined the faculty of MIT in 1979. From 1982 to 1983, Krugman spent a year working at the Reagan White House as a staff member of the Council of Economic Advisers. He rejoined MIT as a full professor in 1984. Krugman has also taught at Stanford, Yale, and the London School of Economics.

In 2000, Krugman joined Princeton University as Professor of Economics and International Affairs. He is also currently Centenary Professor at the London School of Economics, and a member of the Group of Thirty international economic body. He has been a research associate at the National Bureau of Economic Research since 1979. Krugman was President of the Eastern Economic Association in 2010.

Paul Krugman has written extensively on international economics, including international trade, economic geography, and international finance. The Research Papers in Economics project ranked him as the 14th most influential economist in the world as of March 2011 based on his academic contributions. Krugman's International Economics: Theory and Policy, co-authored with Maurice Obstfeld, is a standard undergraduate textbook on international economics. He is also co-author, with Robin Wells, of an undergraduate economics text which he says was strongly inspired by the first edition of Paul Samuelson's classic textbook. Krugman also writes on economic topics for the general public, sometimes on international economic topics but also on income distribution and public policy.

The Nobel Prize Committee stated that Krugman's main contribution is his analysis of the effects of economies of scale, combined with the assumption that consumers appreciate diversity, on international trade and on the location of economic activity. The importance of spatial issues in economics has been enhanced by Krugman's ability to popularize this complicated theory with the help of easy-to-read books and state-of-the-art syntheses. "Krugman was beyond doubt the key player in 'placing geographical analysis squarely in the economic mainstream' ... and in conferring it the central role it now assumes."
