Research interests
My research interest is to improve economic welfare of people around the world through policy analysis. For this purpose, many quantitative methods such as econometrics, input output model and computable general equilibrium model has been applied. In addition, I have strong interest on international trade theory.
Geographically, I have focused on Asian countries such as Laos, Cambodia, Nepal and Sri Lanka as well as Japan.
Study example
- Effects of Climate Change on Agricultural Income and Poverty： We are studying the impacts of climate change on agricultural production and income with computable general equilibrium model in Sri Lanka. In this study, the effect of climate change on poverty is also considered with micro simulation module.
- Volatility of International price of rice and poverty. We are studying the relation between volatility of international price of rice and poverty. Especially correlation of yield variation among rice producing countries are carefully examined since it induce “systemic risk” of higher volatility of international price. Monte Carlo simulation was employed with rice trade model.
- Impact evaluation of micro finance. Micro finance has two objectives: one is microeconomic objective such as improving household welfare (income) and macroeconomic objective for national economic growth. We evaluate both effects in this study. We employ project evaluation method for testing the increase in rural household income due to microfinance in VietNum, then evaluate macroeconomic effect based on modified input output analysis with income linkage.
- The effects of African Swine Fever outbreak in China. China, who has a very big share of swine raising, about 50%, experienced the outbreak of ASF. We examine the effect of ASF outbreak in China on international price with employing partial equilibrium international trade model. In addition, we also evaluated an impact of ASF spread into Japan by using interregional input output model.
- Quantitative agricultural policy evaluation. We evaluated, for example, Japanese domestic dairy policy with partial equilibrium model, and also evaluate the effect of trade liberalization such as TPP with computable general equilibrium model.
