本文推导了具有差异化产品的伯特兰双寡头垄断下的最大收益关税和最优福利关税。结果表明,贝特朗双寡头垄断下的两种关税都比古诺双寡头垄断下的低。此外,在贝特朗双寡头和古诺双寡头垄断下,最优福利关税可能超过最大收入关税。国内企业的成本相对于外国企业的成本越低,产品的可替代性越大,就越有可能出现这种结果。此外,研究还表明,在贝特朗双寡头垄断下,最优福利关税比在古诺双寡头垄断下更不可能超过最大收入关税。
This article derives the maximum-revenue tariff and the optimum-welfare tariff under Bertrand duopoly with differentiated products. It is shown that both tariffs are lower under Bertrand duopoly than under Cournot duopoly. Also, the optimum-welfare tariff may exceed the maximum-revenue tariff under both Bertrand duopoly and Cournot duopoly. This result is more likely the lower the costs of the home firm relative to the costs of the foreign firm, and the greater the degree of product substitutability. Also, it is shown that the optimum-welfare tariff is less likely to exceed the maximum-revenue tariff under Bertrand duopoly than under Cournot duopoly.
