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.

要旨：We analyze wholesale pricing and retail pricing when a monopolistic manufacturer sells its product to conventional retailer and electronic retailer. As a result we show wholesale price discrimination between conventional retailer and electronic retailer. This reason is that a monopolistic manufacturer wants retailers to compete heavily in the retail market and a monopolistic manufacturer charges higher wholesale price to the retailer having an advantage in the retail market. This behavior of a monopolistic manufacturer distorts a fair retailers' competition and we also show that social welfare is improved at most cases if the government regulates wholesale price discrimination.
