01 Description of Research

My areas of interest are matching theory and market design. Matching theory studies how to organize matching mechanisms that achieve social goals such as efficiency and fairness, and market design applies theory to practical problems in society. My recent research topics are as follows: (1) I studied asymptotic behavior of matching mechanisms as the number of market participants grow, and applied the theory to evaluate robustness of labor matching mechanisms in the U.S. (2) I am developing a theory of “matching with constraints” and applying it to propose mechanisms that improves the matching outcomes in medical match and daycare (nursery school) allocation problems in Japan.
