PHASING IN AND PHASING OUT PROTECTIONISM WITH COSTLY ADJUSTMENTS OF LABOUR 31
Karp, Larry S.; Paul, Thierry.
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 the government is able to commit itself to future policy, the optimal trajectory involves phasing in and then phasing out protection of the dying sector. This contrasts with recommendations of gradual liberalization. Without the ability to make commitments, the equilibrium policy begins with and maintains free trade.

LABOR ADJUSTMENT AND GRADUAL REFORM: IS COMMITMENT IMPORTANT? 31
Karp, Larry S.; Paul, Thierry.
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 to make commitments may be unimportant, and we illustrate this conjecture with numerical examples. For either assumption about commitment ability, the equilibrium policy involves gradual liberalization. The dying sector is protected during the transition to a free market, in order to decrease the amount of unemployment Our results are sensitive to the assumptions about migration.
