“Looking Back and Looking Ahead: Comments from Alumni after Completing the Period of Tenure-Track Faculty”

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 systems, 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.
