本文分析了在对称成本双寡头垄断中，三度价格歧视对产量、利润和福利的影响。与统一价格制度相比，我们提供了在三度价格歧视下双寡头垄断的产出、利润和福利更高(或更低)的充分条件。通过与传统垄断价格歧视的研究结果比较，我们发现双寡头价格歧视下的产出和利润效应与垄断情形下的结果有很大的不同。然而，福利效应非常相似。
In this paper we analyse the effects of third-degree price discrimination on output, profit and welfare in a symmetric cost duopoly. We provide sufficient conditions for output, profit and welfare to be higher (or lower) under third-degree price discrimination in a duopoly, compared with a uniform price regime. Comparing our findings with the traditional results on monopoly price discrimination, we show that the output and profit effects under duopoly price discrimination are very different from those under the monopoly case. However, the welfare effects are very similar.
