Microeconomic theory, General Equilibrium Theory, Game Theory
Recent Research Interests
In summary, my research area is “theoretical study of the effects of information on the economy.”
(1) For the classical theory of competitive markets, I have studied the effect of market incompleteness resulting from informational issues on the economic resource distribution. I derived some general results about the inefficiency of the incomplete financial markets and price forecasts.
(2) I made some contributions to the foundation of the non-expected utility theory that critically developed the classical expected utility theory and the Bayesian decision theory, and published several research papers on the presentation of a new decision-making framework.
(3) I proposed a new concept of “information robustness” in general strategic situations (games) with incomplete information. I published some articles about games incorporating the above non-expected utility theory.
In addition to the above areas, I am also conducting research on analyzing Japanese and Chinese classics and everyday matters from the perspective of economic theory.
