  • 演講摘要 : There is much literature on the link between international trade, productivity growth and wage differential of skilled and unskilled labor. The theoretical and empirical research is mainly based on the Heckscher-Ohlin-Samuelson framework and on cases of large countries. More comprehensive theoretical models are needed to guide further empirical research. This paper contributes to the debate by providing a dynamic intertemporal general equilibrium (DIGE) model incorporating endogenous skill formation. Both the short- and long-run transition mechanism with shocks can be illustrated. Also, it proposes education as an important factor in the determination of the wage differential. The result supports the argument that trade has a responsibility for an increase wage differential. A cut in government education investment tends to enlarge the wage differential. In contrast to the existing literature, this paper suggests that productivity growth may not be the cause of an enlarging wage differential in the long run.
