中文摘要
我们在一般寡头模型中研究个性化定价。相对于统一定价，个性化定价的影响取决于市场覆盖率。如果市场条件使得覆盖率较高（例如，生产成本较低或企业数量较多），个性化定价损害企业并有益于消费者；反之，若覆盖率较低，则结论相反。当仅有部分企业拥有数据以实行个性化定价时，与所有企业或没有企业实行个性化定价的情形相比，消费者的境况可能更差。(JEL D21, D43, D82)
Abstract
We study personalized pricing in a general oligopoly model. The impact of personalized pricing relative to uniform pricing hinges on the degree of market coverage. If market conditions are such that coverage is high (e.g., the production cost is low or the number of firms is high), personalized pricing harms firms and benefits consumers, whereas the opposite is true if coverage is low. When only some firms have data to personalize prices, consumers can be worse off compared to when either all or no firms personalize prices. (JEL D21, D43, D82)
