Paul Robin Krugman was born on February 28, 1953, in Albany, New York, and grew up in Merrick, Long Island. His interest in economics was inspired by Isaac Asimov’s “Foundation” novels, which depicted a future where social scientists used “psychohistory” to guide civilization, leading Krugman to pursue economics as the closest real-world equivalent. He earned his BA summa cum laude in economics from Yale University in 1974 and completed his PhD in economics from the Massachusetts Institute of Technology (MIT) in just three years, in 1977. His doctoral thesis, “Essays on Flexible Exchange Rates,” was supervised by Rudi Dornbusch, whom Krugman credits as a major influence on his career.
Krugman began his academic career as an assistant professor at Yale in 1977 before joining MIT in 1979. He served as a staff member for the Council of Economic Advisers in the Reagan White House from 1982 to 1983, gaining insight into policy-making. He returned to MIT as a full professor in 1984 and also taught at Stanford and the London School of Economics. In 2000, he joined Princeton University as a Professor of Economics and International Affairs, a role he held until his retirement in June 2015, becoming a professor emeritus. He then joined the Graduate Center of the City University of New York as a Distinguished Professor of Economics. His early work significantly advanced international economics, particularly his contributions to new trade theory and new economic geography, which ultimately earned him the Nobel Memorial Prize in Economic Sciences in 2008.
This groundbreaking work explained patterns of international trade and the geographic distribution of economic activity by integrating economies of scale and consumer preferences for diverse goods into economic models. His 1979 paper on monopolistically competitive trade models highlighted how trade occurs between similar countries due to consumer preference for diverse brands and economies of scale in production. His 1991 paper, “Increasing Returns and Economic Geography,” further developed these ideas into the “new economic geography,” explaining economic agglomeration in core regions through the interaction of increasing returns, trade costs, and factor price differences. Beyond academia, Krugman became a prominent public intellectual, writing hundreds of columns for The New York Times from 2000 to 2024, where he provided commentary on a wide range of economic and political issues, influencing public discourse.
