Ryo Okui is a professor at the University of Tokyo, specializing in Econometrics and Applied Microeconomics. His research focuses on econometric methods for dynamic panel data models, model averaging, and instrumental variable estimation. He has developed techniques for robust inference in the presence of heteroscedasticity and many moment conditions. His work also addresses structural breaks in panel data and the construction of optimal instruments through first-stage prediction averaging. Okui's contributions include the development of doubly robust methods for estimating treatment effects and confidence sets for group membership in panel data models.
