Ph.D. Candidate in Economics, University of Tokyo
I am a Ph.D. candidate in Economics at the University of Tokyo, advised by Professor Kosuke Aoki. My research lies at the intersection of monetary economics, macroeconomics, and international finance. I study how digital currency and payment infrastructures shape currency competition, international transactions, household consumption, and monetary policy transmission.
My current research examines stablecoin entry and monetary sovereignty, the role of payment speed in currency invoicing, and the effects of digital financial inclusion on household consumption in China.
