Leslie M. Marx
Professor of Economics
Leslie M. Marx, PhD, Robert A. Bandeen Professor of Economics; BS (Duke University), MA (Northwestern University), PhD (Northwestern University) Professor Marx has research interests in game theory and industrial organization. Professor Marx’s research focuses on the problem of anti-competitive behavior by individuals and firms, including collusion, bid rigging, and anti-competitive contract provisions. This research improves our ability to detect collusion, teaches us how auctions and other markets can be made less susceptible to collusion, and guides antitrust authorities in understanding what behavior should be viewed as anti-competitive. Professor Marx’s research has appeared in such publications as American Economic Review, Review of Economic Studies, Journal of Political Economy, and Quarterly Journal of Economics. She authored the 2012 book The Economics of Collusion: Cartels and Bidding Rings, published by MIT Press. She is currently on the editorial boards for International Journal of Game Theory and American Economic Journal: Microeconomics. She is the recipient of two National Science Foundation research grants, a National Science Foundation Graduate Fellowship, and a Sloan Doctoral Dissertation Fellowship. Professor Marx was a member of the 1996 U.S. Olympic Fencing Team.
