本文分析了福利下的差别与统一定价的寡头垄断,使不同的服务成本。我们建立必要和充分条件的需求属性交叉/自己的弹性和曲率的差异定价对称企业提高总消费者剩余,利润和总福利。分析直观地揭示了为什么差别定价通常是有益的,但并不总是,包括为什么利润可以下降,不像垄断,为什么它是更有益于寡头垄断的第三度价格歧视。然而,当企业有不对称的成本,差别定价可以减少利润或消费者剩余,即使是“简单”的需求,如线性。
This paper analyzes welfare under differential versus uniform pricing across oligopoly makes that differ in costs of service. We establish necessary and sufficient conditions on demand properties—cross/own elasticities and curvature—for differential pricing by symmetric firms to raise aggregate consumer surplus, profit, and total welfare. The analysis reveals intuitively why differential pricing is generally beneficial though not always—including why profit can fall, unlike for monopoly—and why it is more beneficial than oligopoly third-degree price discrimination. When firms have asymmetric costs, however, differential pricing can reduce profit or consumer surplus even with ‘simple’ demands such as linear.
