要旨：We propose a novel long-term migration dynamics that can overcome the equilibrium indeterminacy of Core-Periphery (CP) model a la Krugman [1991b]. This goal is achieved by introducing uncertainty of economic environment into CP model with forward-looking migration dynamics. We show that an equilibrium path of migration dynamics can be uniquely determined in accordance with each stochastic sample path.

要旨：In this paper, we focus on the impacts of trade on workers' skill formation and wage structure in the presence of heterogeneous workers. As unskilled, workers are identical in their productivity. If workers train himself / herself, he/she becomes a skilled worker. We assume that workers are heterogeneous in their training costs. With above settings, we show that trade openness enhances skill formation and raises the real wage disparity between skilled and unskilled workers though it makes welfare of all agents better off. In addition, trade openness leads to rises in income inequality in some parameter ranges. Finally, we show that compared to export, FDI enhances skill formation, when the fixed costs for FDI is small, or the number of trade partner countries is large, or transport costs of manufactured goods are high.
