摘要

Abstract of the paper

 We present a simple Cournot model for determining the optimal discriminatory tariff rates under the cases of benevolent government, domestic ownership, and opportunism. The main finding of this paper are as follows. First, under the benevolent government, the optimal tariff can be negative. The optimal tariff difference is half of the marginal cost difference if the consumer surplus oriented weight is not very large, and it is independent of the weight. Second, the domestic government may impose lower tariff to the more efficient firm when the domestic investor partially owns the more efficient firm. Third, under unobservable contract, the optimal tariffs are lower than those under observable contract, and the optimal tariff difference is two thirds of the marginal cost difference.
