Incomplete information between a firm and consumers or a seller and buyers is a key concept to understand economic relationships and markets. Over the past fifteen years, empirical research has applied these models to analyze auction, insurance and pricing data. Professor Perrigne and Professor Vuong have been major contributors to this area through the development of new econometric methods. They will give lectures on empirical auctions and nonlinear pricing on Thursday and Friday October 17th and 18th. The lectures will cover econometric tools and empirical applications for a deep understanding of market mechanisms.
