Steven D. Levitt

Steven D. Levitt is an American economist whose Freakonomics, co-written with Stephen J. Dubner, applied economic thinking to unexpected social questions and became a pop-culture phenomenon.

Steven D. Levitt is a professor of economics at the University of Chicago and the winner of the John Bates Clark Medal, awarded to economists under forty who have made the most significant contribution to the field. His academic work uses economic tools and datasets to study unconventional questions — the economics of drug dealing, the incentive structures of sumo wrestlers, the effects of abortion legalisation on crime rates. Freakonomics (2005), co-written with New York Times journalist Stephen J. Dubner, brought these methods and questions to a general audience and became one of the most successful popular economics books ever published.

The book’s appeal lies in its combination of genuine methodological cleverness and provocative subject matter. Levitt’s approach — find unexpected data, look for hidden incentives, challenge conventional wisdom — is genuinely illuminating as a demonstration of how economic thinking can reframe a question. The chapter arguing that the legalisation of abortion in the 1970s was a significant factor in the American crime decline of the 1990s (the Donohue-Levitt hypothesis) is the most controversial and has generated an ongoing academic debate. Other findings in the book have replicated better than this central claim.

The criticisms of Freakonomics and its sequels (SuperFreakonomics, Think Like a Freak, When to Rob a Bank) are twofold. First, the empirical findings are treated with more confidence than the academic debate warrants — Levitt’s academic papers generate more caution than his popular work suggests. Second, the rhetorical move of “the surprising truth” can itself become a formula, privileging counterintuitive conclusions over accurate ones. The book is more valuable as a demonstration of a mode of questioning than as a collection of reliable facts, and readers who understand that distinction will get more from it.
