电信运营商双寡头定价机制设计

电信市场存在运营商之间的竞争关系,运营商针对异质性消费者的定价机制设计更是直接影响其利润的实现,本文利用机制设计方法,分析了电信运营商的双寡头垄断定价策略,研究发现:(1)运营商的核心利润来源于低类型消费者的总剩余。低类型消费者的消费扭曲来源于运营商提供给高类型消费者过高的信息成本。要想改善低类型消费者的不满和消费扭曲,需要降低对高类型消费者的优惠幅度。(2)电信运营商的最优定价随竞争对手的价格同向变动。(3)电信运营商最优定价与消费者对该运营商的服务体验成正比,与消费者对竞争对手运营商的服务体验成反比。所以,运营商应当不断优化自己网络的服务质量,提高消费者的服务体验,进而才能有涨价的空间。

Optimal Pricing Mechanisms for Mobile Service Providers Under Duopoly Competition

Due to competition in the wireless communication market, the pricing mechanisms of mobile service providers determine their profit. In this paper, we use mechanism design to analyze the optimal pricing strategies for service providers towards heterogeneous consumers under duopoly competition. The major findings are threefold: (1)the majority of the profit of service providers comes from low type consumers, and there exist usage distortion of low type consumers roots from the information rent that service providers give to high type consumers. Therefore, service providers should lower the preferential margins to high type consumers to stimulate the consumption of low type consumers; (2)the optimal pricing menu offered by a service provider is positively correlated with that of her competitor; and (3)the optimal pricing menu of a service provider is positively correlated with her service level, and negatively correlated with the service level of her competitor. In other words, besides offering competitive pricing, service providers should constantly improve their service level in order to create higher profit.
