Kohei Yata
Kohei’s research interests are in econometric theory and applied econometrics, and particularly in policy evaluation and optimization. Kohei’s job market paper, titled “Optimal Decision Rules Under Partial Identification,” considers a class of statistical decision problems in which the policy maker must decide between two alternative policies to maximize social welfare (e.g., the population mean of an outcome) based on a finite sample. The paper uses an empirical application to a school construction program in Burkina Faso, where villages were selected to receive schools based on scores computed from their characteristics. In August 2022, Kohei will join the Department of Economics at the University of Wisconsin-Madison as an Assistant Professor.
