[Industrial organization theory]
Theoretical industrial organization theory that applies game theory is the main research theme. We elucidate the mechanism of industrial development by grasping the impact of strategic actions by companies and policies by governments on the development and evolution of their industries.
[The Economics of Social Welfare (Family Economics)]
Based on the economics of the family, we are working to elucidate various welfare issues from an economic perspective. For example, we have created a model that endogenously determines the number of births in relation to heritage motivation, and have examined the issue of declining birthrates. In the future, we would like to elucidate the issues of social welfare in the relationship between the local community and the family.

A.The goal is to take up various issues related to corporate strategy as case studies, and to learn specific corporate strategy. In fact, all members of the seminar discuss how the company should address the strategic issues that have arisen in the company, and explore the ideal way of corporate strategy.
B.Learn about behavioral economics, which has made remarkable progress in recent years. Through experimental observation of living human beings, we will consider what actions are taken in reality, and aim to rebuild economics through this.
