Instructor: Fuhito Kojima Department of Economics, Stanford University fuhitokojima1979 “at” gmail.com (replace “at” with @) Syllabus How to match people to other people or goods is an important problem in society. Just think of some examples such as (1) student placement in schools, (2) labor markets where workers and firms are matched, and (3) organ donation, in which patients are matched to potential donors. The economics of “matching and market design”' has analyzed these problems and improved real-life institutions in recent years. For example, economists have helped (1) NYC and Boston design their school choice programs, (2) medical communities reorganize their hiring procedure, and (3) organize systematic kidney exchange mechanisms to give kidneys to as many patients as possible.
This course introduces the theory of matching and market design, and discusses how the theory can be applied to these (and other) applications. I will put emphasis on recent advances in the topic and present open questions so that interested students can promptly come to the frontier and begin their own research.
