This paper characterizes the interactions among studying abroad, return migration, and capital accumulation, in a two-country overlapping generations model with households of heterogeneous ability. The model exhibits positive selection of migration status (i.e., permanent, return, and...

We formulate a two-country, two-good, two-factor, two-period-lived overlapping generations model to examine how population aging determines the pattern of and gains from trade. Two main results are obtained. First, the aging country endogenously becomes a small country exporting the...

This paper studies the endogenous relationship between direct foreign　investment (DFI) and trade restriction. A domestic labor union interested in both employment and wages bargains with a foreign firm and lobbies against foreign imports. By endogeneizing the wage rate and incorporating...

This paper examines how impatience interacts with inequalities in economic devel- opment. In a society of intrinsic inequality, we show that (i) poor households tend to bene…t more from positive shocks under decreasing marginal impatience (DMI) than un- der constant marginal impatience (CMI)...

This paper examines how impatience interacts with inequalities in economic development. In a society of intrinsic inequality, we show that (i) poor households tend to benefit more from positive shocks under decreasing marginal impatience (DMI) than uner constant marginal impatience (CMI) and...

This paper examines the role of dual sourcing (e.g., outside options) in vertical and horizontal relations. In a bilateral monopoly market, if either the upstream or downstream firm has outside options, the other firm could lose from seemingly positive shocks, e.g., market expansion or...

This paper examines the relationship between resource development and industrialization. When transport costs are high, the region with a more valuable natural resource enjoys a higher welfare than the other region. However, as transport costs decrease, firms begin to move out of the region,...

We model the production allocation choices of a multinational enterprise (MNE) in a three-country framework-one northern country and two southern ones. Products made in the South are of lower quality than those made in the North. Substitutability between goods differs due to variations in...
