Personalized Pricing and Competition
研究一般寡头模型中个性化定价相对于统一定价的影响，发现市场覆盖程度是关键：高覆盖时个性化定价损害企业、有利消费者，低覆盖时相反。
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.
