Roger Myerson is the Glen A. Lloyd Distinguished Service Professor of Economics at the University of Chicago. Professor Myerson has made seminal contributions to the fields of economics and political science. In game theory, he introduced refinements of Nash’s equilibrium concept, and he developed techniques to characterize the effects of communication when individuals have different information. His analysis of incentive constraints in economic communication introduced some of the fundamental ideas in mechanism design theory, including the revelation principle and the revenue-equivalence theorem in auctions and bargaining. Professor Myerson has also applied game-theoretic tools to political science, analyzing how political incentives can be affected by different electoral systems and constitutional structures. Professor Myerson has a PhD from Harvard University and taught for 25 years at the Kellogg School of Management at Northwestern University before coming to the University of Chicago in 2001. He is a member of the American Academy of Arts and Sciences and of the National Academy of Sciences. In 2007, he was awarded the 2007 Nobel Memorial Prize in Economic Sciences in recognition of his contributions to mechanism design theory.
