The effect of risk aversion on Nash equilibrium trade restrictions is studied using numerical methods. An increase in a nation's level of risk aversion can lead to either an increase or decrease in its equilibrium restriction and either an increase or decrease in its rival's restriction. The...

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...

Optimal distortions for the agricultural sector are calculated taking as given distortions in the nonagricultural sector. The calculations use a general equilibrium model and assume that the sole criterion is economic efficiency. For most agricultural commodities, existing distortions should be...

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 the situation where two large countries impose either tariffs or quotas and a third large country remains passive. The introduction of the third country overturns results from two-country models. Stable quota equilibria are capable of reproducing the equilibrium price under tariffs, and...

The authors study a model in which a customs union trades with countries that behave strategically. Provided that the members of the customs unions are similar but not identical, they show that both in the case in which intraunion transfers are allowed as well as in the one in which they are...

If capital lowers marginal cost and a firm with more capital gets a bigger share of the surplus in merger bargaining, then the equilibrium price with a merger may be lower than without a merger. If entry is restricted, the level of industry profits minus investment costs may be higher if mergers...
