[Industrial organization theory]
The main research theme is theoretical industrial organization theory that applies game theory. We are elucidating the mechanisms of industrial development, taking into account how strategic actions by companies and government policies affect the development and evolution of the industry.
[Economics of Social Welfare (Family Economics)]
Based on the economics of the family, we are working on elucidating various welfare issues from an economic perspective. For example, we have created a model that determines the number of births endogenously in relation to heritage motives, and have considered the problem of declining birthrate. In the future, I would like to elucidate social welfare issues in the context of the community and family.

A.The goal is to take up various issues related to corporate strategy as case studies, and to learn concrete corporate strategies. We take up strategic issues that have actually occurred in companies, and discuss how companies should address them, and explore the ideal way of corporate strategies.
B.Learn behavioral economics, which have made remarkable progress in recent years. Through experimental observations of living humans (humans), we will consider what actions are taken in reality, and through this, we aim to rebuild economics.
