The trade theorist who became America's most argued-over columnist

Krugman's grandparents came from Ukraine, arriving in 1914 and 1920, and he grew up in Albany reading science fiction, wanting by his own account to be Hari Seldon, Isaac Asimov's fictional mathematician who predicts the future of civilizations. Economics turned out to be the closest working substitute. He graduated summa cum laude from Yale in 1974, finished a PhD at MIT in 1977, and within five years was serving on Ronald Reagan's Council of Economic Advisers, a self-described defender of the welfare state working inside a Republican White House. Back at MIT as a full professor by 1984, he published the papers that made his academic name: a 1979 model explaining why similar countries trade heavily with each other, and a 1991 paper founding new economic geography.

The 2008 Nobel Memorial Prize in Economic Sciences went to him alone, for folding economies of scale into standard trade models and explaining why manufacturing clusters where it does. By then he had a second, louder career: a New York Times column that started in 2000 and turned an academic trade theorist into one of the most widely read voices in American political commentary, arguing for Keynesian stimulus through two recessions and building a running critique of Republican and, at times, Democratic economic policy. He retired the column in December 2024, after twenty-four years, and immediately started a Substack newsletter that pulled several hundred thousand readers a post — an audience the tenure system never measures.

Krugman's most quoted wrong call is a line from 1998: that by 2005, the internet's impact on the economy would prove no greater than the fax machine's. He later said he had meant it as provocation rather than forecasting, a defense he has rarely extended to the Bush, Obama or Trump officials he spent two decades accusing of shading their own numbers. The New York Times' own ombudsman, Daniel Okrent, once accused him of a disturbing habit of shaping, slicing and selectively citing figures in his column. And well before any of that, in 1982, the self-described defender of the American welfare state spent a year on Ronald Reagan's Council of Economic Advisers, an experience he later called thrilling and then disillusioning, in that order.

Twenty-four years of column-writing turned an economics professor into a genuine culture-war figure, cited by supporters as the conscience of mainstream economics and dismissed by critics as a partisan brand with a Nobel attached. Both readings undersell the real split in his career: the trade and geography models remain standard tools in economics departments regardless of anyone's politics, taught to students who have never read a single column. He is seventy-three, still writing daily on Substack, still teaching at the CUNY Graduate Center, and the two versions of his reputation — the theorist and the pundit — show no sign of settling into one.
