Jonathan Levin

Microeconomist who works on a broad range of topics including the economics of contracting, auctions and marketplace design, credit and insurance markets, and empirical methods for studying imperfect competition. Early research clarifies the nature of long-term contractual relationships where parties cannot write fully enforceable contracts. Research on auctions and internet markets examines the role of market design in promoting competition and market efficiency. Helped pioneer empirical methods to analyze markets with asymmetric information, applying those to problems in sub-prime credit markets, and subsequently to health insurance. Developed a widely used approach to estimating dynamic models of imperfect competition. Recipient of the John Bates Clark Medal (2011).
