討論提要

The paper intends to design an alternative channel by which a non-tariff trade policy can be transformed into an equivalent tariff policy. To do so, the paper employs a two-stage model in which trade policy is determined by the policy makers in the first stage and taking Cournot-conjecture firms compete with each other in the second stage. The product differentiation is also considered in the model.

結論

1.      Suppose quota rents can be replaced with monetary incomes such as equivalent tariff revenues. The relationship between tariffs and quotas can be transformed bilaterally.

2.      The relationship between the degree of product differentiation and the optimal tariff rate can be derived. In general, the optimal tariff increases in the degree of product differentiation.

延伸研究

1.      The results under different market structure need to be examined.

2.      It can be interesting to consider the model with political activities such as lobbying.
