Outline of Final Research Achievements

We constructed a partial equilibrium model of multiproduct firms with international trade. Assuming heterogeneity in productivity of firms, we examined the impacts of falling trade costs on the numbers of firms and varieties and economic welfare in each country, and analyzed the home market effect and locational advantage.
We then constructed a general equilibrium model and investigated the impacts of progress in production technology on regional economic activities. By endogenizing supply of working hours, we could obtain several interesting results. We also explored regional economic policies by focusing on interregional differentials in per capita income and social welfare.
