Tax fraud, terrorists’ checking accounts and prostitution were just a few of the topics covered in a guest lecture Friday by award-winning economist and author Steven Levitt. The talk — entitled “Freakonomics: A Rogue Economist Explores the Hidden Side of Everything” — was part of the annual Thomas H. Quinn Lecture series.

Mendoza College of Business dean Martijn Cremers introduced Levitt, an economist and co-author of “Freakonomics.” The book spent more than eight years on the New York Times bestseller list in the U.S. and sold over 7 million copies worldwide. Currently, Levitt is a University of Chicago economics professor. Throughout the lecture, Levitt shared anecdotes from his career as a researcher.
