Price competition between two international firms facing tariffs
研究了关税对销售同质产品的定价双寡头的影响，发现提高关税会使两家企业利润都增加，但受保护企业获益更多。
This paper examines the effects of tariffs on price-setting duopolists selling a homogeneous product. The producers cannot segment geographically distinct markets. It provides a complete characterization of the equilibrium (mixed) strategies and analyzes the pattern of competition for different tariffs. If a country raises its tariff, the profits of both producers increase, although the protected firm typically benefits more than its foreign counterpart. Growth in one market may reduce the profits of the firm located in the other market.
