We study the optimal trade policy against a foreign oligopoly withendogenous quality. We show that, under the Most Favoured Nation(MFN) clause, a uniform tariff policy is always welfare improvingover the free trade equilibrium. However, a nonuniform tariff policyis always desirable on welfare...

This paper examines the effects of foreign entry, in the form of either imports or direct foreign investment, into an oligopolistic market. Incorporating a possible divergence between private and social costs, it first derives simple conditions under which foreign entry reduces welfare relative...

We formulate a dynamic game model of trade in an exhaustible resource with a quantity-setting cartel. We compute the feedback Nash equilibrium and two Stackelberg equilibria under two different leadership scenarios: leadership by the strategic importing country, and leadership by the exporting...

Pre-tax car prices are particularly low in EU countries with high registration taxes but no car production, meaning that the tax is equivalent to an import tariff and induces international price discrimination. The paper develops a theorectical model to analyse the European Commission's policy...

We derive formulas for the optimal tariff rate in four theoretical models. We start with a model in which industries are competitive and then successively allow for: monopoly pricing by export industries; revenue-replacement costs; and cold-shower effects. The theoretical formulas accurately...
