[Industrial Organizations]
The main research theme is theoretical industrial organization theory that applies game theory. We investigate how strategic actions by companies and government policies affect the development and evolution of their industries, and elucidate the mechanisms of industrial development.
Economics of Social Welfare (Family Economics)
Based on family economics, we are working to elucidate various welfare issues from an economic perspective. For example, we have created a model in which the number of births is determined endogenously in relation to heritage motives and examined the issue of declining birthrates. In the future, we would like to elucidate the problems of social welfare in the relationship between local communities and their families.

A.The goal is to examine various issues related to corporate strategy as case studies, and to learn concrete corporate strategy. All the seminar members discuss how the company should address the strategic problems that have actually occurred in companies and discuss how the company should address them.
B.Learn about behavioral economics, which has been making remarkable progress in recent years. Through experimental observations of living humans (humans), we will consider what actions are actually taken and aim to rebuild economics through this.
