Recent Research Interests

My principal research field is economic growth theory and social security policy. In particular, I have been interested in the macroeconomic implications of an aging population since I started my graduate work at Osaka University. Population aging is one of the key demographic trends facing the world today and might have significant macroeconomic influence through changes in saving rates, the rate of return on assets, the balance of payments, the composition of production and consumption, changes in fiscal environments of social security, and changes in the political power of the elderly relative to the young. Currently, I plan to build growth models that consider the effects of aging on the productive structure of the economy.
