Professor of Economics
The goal of Kota Saito's research is to study individual decision making. His main focus is in decision theory, developing mathematical models of decision making that account for some of the behavioral regularities documented in experimental economics and psychology.
Saito's research has centered around five main topics: (i) decision making under uncertainty, (ii) other-regarding preferences, (iii) time preferences, (iv) the role of perception in stochastic choice, and (v) response time in various decision making. Depending on the purpose of each study, he uses three primary tools: (a) preference relation, (b) consumption-price data, and (c) stochastic choice function.
