| Popis: | 107 This paper uses the three-country two-firm model to explore the global welfare level between the unified tariff system and the differential tariff system in the case of network externalities and product heterogeneity. It is found that (a) without network externalities and homogeneity of products, the global welfare of uniform tariffs is greater than that of differential tariffs. (b) In the absence of network externalities, when the product is different from the product, the greater the product difference, the global welfare of the unified tariff is smaller than the differential tariff, and the smaller the product difference, the opposite result will be obtained. (c) In the case of network externalities and product heterogeneity, the greater the product differences and the smaller the network externalities, the smaller the global welfare of uniform tariffs than that of differential tariffs. The smaller the product differences and the smaller the network externalities, or the greater the network externalities and the heterogeneity of products, the opposite result will be obtained. |
