CESPRI Working Paper No. 188
This paper addresses the role of mobility costs in shaping the effects of trade integration on wage inequality and welfare. We present a three-factor, two-sector model in which the production technology exhibits capital-skill complementarity and the cost of moving across sectors differs between unskilled and skilled workers. We consider a proportional tax on skilled workers' wage that is used to finance a re-training program to reduce the mobility costs of unskilled workers. We show that if the training program is sufficiently effective, a positive tax rate can both reduce wage inequalities and reinforce the welfare-enhancing effects of trade integration. In addition we show that, even when the public programme entails some welfare losses, it can make trade integration Pareto superior with respect to autarky.
