We study the dynamics of optimal trade policy in a model with costly inter-sectoral adjustment of labour, where migrants pay less than the marginal social cost of migration. If workers have rational expectations, a future tariff has an announcement effect on the current migration decision. If...

We analyze a model in which a government uses a second best policy to affect the reallocation of labor, following a change in relative prices. We consider two extreme cases, in which the government has either unlimited or negligible ability to commit to future actions. We explain why the ability...

We model adjustment costs in a general equilibrium setting using a “transport sectorâ€. This sector provides services needed to re-allocate a factor of production across wo other sectors. A market imperfection in the transport sector causes adjustment to occur too slowly in the absence...

We compare the advantages of targeting either the growing sector or the shrinking sector in an economy where migration occurs too slowly, and the government has only second-best policy instruments. If the government is able to make commitments, we show (in a special case) that it should target...
