This paper examines the optimal entry policy towards oligopoly in an globalized world. In an open economy free entry is socially suboptimal, but corrective tax policy to curb entry proves insufficient unless internationally harmonized. Thus, while conferring the gains from trade, globalization...

This study develops an on-the-job search model involving spatial structure. In this model, workers are either employed and commuting frequently to a central business district (CBD) or unemployed and commuting less frequently to the CBD to search for a job. When an unemployed worker succeeds in...

This paper investigates which of the two countries \resource-rich or resourcepoor\ gains from capital market integration and capital tax competition. We develop a framework involving vertical linkages via resource-based inputs as well as international fiscal linkages between resource-rich and...

This paper develops an overlapping generations model that involves the endogenous determination of fertility and an explicit city structure in order to analyze fully the social and natural changes in city populations. We provide conditions under which the model exhibits the spatial features of...

The welfare effects of capital market integration are examined under a model of tax competition with two asymmetric countries. The asymmetry is expressed through the labor market: one country has a perfect labor market whereas the other country is unionized. Our results show that the welfare...

In order to examine the impacts of market size on entrepreneurship, we estimate a monopolistic competition model that involves entrepreneurial decision by using data on Japanese prefectures. Our results show that a larger market size measured by the population density leads to higher incentive...

This paper develops an overlapping generations model that involves endogenous determination of fertility and explicit city structure. We provide conditions under which there exists a unique steady state, which can replicate spatial features of demography observed in Japanese cities. We also...

We investigate the role of firm heterogeneity in considering profitability and desirability of mergers in the international economy. Analysis shows that higher trade costs make only crossborder mergers profitable whereas larger firm heterogeneity is likely to increase both domestic and...

In this paper, we focus on the skill formation when considering the trade impacts on labor markets. Although workers are identical as unskilled labor, they differ in their productivity as skilled. Workers become skilled by incurring the training costs. Introducing the above settings into a trade...

This paper analyzes the interactions between labor and housing (and land) markets in a city. We develop a monocentric city model involving land development and frictional unemployment. Unemployment, the spatial structure of a city, land development, housing demand, prices of housing and land are...
