Matsuyama’s main fields of research are international trade and macroeconomics. In particular, he has worked extensively on such topics as north-south trade, economic growth, economic development, income inequality, structural change, and endogenous economic fluctuations. He is, in his own words, “interested in understanding the mechanisms behind macroeconomic instability, structural transformation, as well as inequality across countries, regions, and households, and how they interact with credit market imperfections and product market innovations.”^[6]
