Public Finance
Ph.D. (Univ.of Minnesota)

While the Japanese fiscal structure is forced to change for adjusting the new era, we cannot find any good solution in the traditional economic theory. As a solution to this problem, I propose the institutional analysis, in which the relation between an institution and its mechanism is clarified. According to a law, which is an institution, I construct a economic model by formulating it mathematically and considering an agent’s rational behavior. By using a real model instead of a fictional one, I clarify what kind of mechanism occurs in any given institution. Using this institutional analysis, I clarify the mechanism in the current system and try to find a desirable institution in the fields of a tax system, government debt, local government finance, public pension, public medical care, public assistance for the poor, and the fiscal investment and loan program.

Financial Theory
Ph.D.(Univ. of Tokyo)
WEB site

I theoretically analyze financial phenomena from the view that economic subjects interact each other through various financial networks. Especially, I analyze network of money circulation, utilizing a self-developed analytical framework termed as graph finance theory. The framework has strength in expressing (relative) velocity of money for general network structure.
My recent researches deal with topics in the field of payment system, where various problems relevant to money circulation would be presented in a prototypical manner. I proceed researches on effects of liquidity-saving mechanism under RTGS systems, or on roles of central counterparty on settlement efficiency, intensively in relation to network structure.
