Research Interest

Based on a variety of field surveys in Asia and Africa, I attempted to construct strategy for agricultural and industrial development. Specifically I attempt to explore the reasons why successful Asian rice green revolution cannot be transferred to sub-Saharan Africa and how high-value agriculture can be built by means of contract farming. I also inquire the roles of industrial cluster and foreign direct investment in the development of local industries.

Applied Microeconomics


There are three important abilities to carry out valuable empirical research: (1) understanding of microeconomics, (2) knowledge of econometrics, and (3) understanding of reality. Students are advised to make maximum efforts to study microeconomics and econometrics.
