Recent Research Interests

An aging society with fewer children is increasingly the situation in Japan and it brings about serious problems. Expenditures for social security programs, such as public pension, medical insurance, long-term care, etc, continues to increase. On the other hand, the number of younger people continues to decrease because of a decrease in total fertility rate. Therefore, the sustainability of the social security system is doubtful, because the government can not collect enough tax revenue. It is important to consider the sustainability of the social security system. I am interested in how the government should reform the social security system to make it sustainable.

Concretely, I examine how the government can collect enough tax revenue, how the government can provide pension benefits for older people to reduce income inequality and how the government can implement a provide child care policy that increase the fertility rate in an aging society with fewer children.
