This paper applies a vertical difference model to investigate the optimal import tariff, optimal counterfeit-captured rate, and the welfare effects in the presence of counterfeit of status goods from the viewpoint of southern side. Three major results are concluded. (1) Regardless of the detecting cost, the optimal counterfeit-captured rate equals to the minimum rate that could drive out the counterfeit. (2)When there is potential counterfeiting, the optimal import tariff and social welfare decrease. (3) In the cases of the quality of counterfeit declining, the status of brand-name products rising, the negative externality getting higher, the marginal cost of genuine firm reducing, or the marginal cost of counterfeiting firm increasing, the difference of the optimal tariff between counterfeiting and non-counterfeiting scenarios would be enlarged. |
