Previous research

The purpose of this section of my Ph.D. dissertation is to estimate Japan’s demand and supply structure for raw milk, fluid milk, and dairy products; to build demand–supply models; and to conduct a simulation analysis of trade policy and distribution system. Additionally, I have included a study of agricultural economics and veterinary epidemiology on the impact of mastitis on raw milk supply, concretely considering the problem of butter shortage. After earning my degree of postdoctoral fellowship, I have been researching the effect of climate change on yield variations of rice, volatility of international prices for rice, and associated poverty in developing countries within the field of agricultural development and environmental economics.

 

Current research projects

I am currently working on the following two main areas. The first is estimation of demand for agricultural imports, and the second is verification of the possibility of aggregation of consumer goods using large-scale POS data.
(1) In simulation analysis of trade policies and systems, the degree of substitution between domestic and imported agricultural products is a key parameter. The aim of this research is to estimate it quantitatively from a structural model based on economic theory, and to contribute to agricultural trade policy.
(2) Statistical verification of economic theory using large-scale data is becoming popular, against a background of improving computer processing capacity and increasing availability of microdata. By using large-scale POS data, the characteristics of the demand function derived from consumer theory are verified for a composite commodity, and their validity is clarified.
