Welfare implications of personalized pricing in competitive platform markets: The role of network effects
研究双寡头平台市场中个性化定价对消费者福利的影响，发现个性化定价虽降低开发者费用但提高消费者价格，网络效应使平台获利而消费者受损。
This study explores the welfare impact of personalized pricing for consumers in a duopolistic two-sided market, with consumers single-homing and developers affiliating with a platform according to their outside option. Personalized pricing, which is private in nature, cannot influence expectations regarding the network sizes, inducing the platforms to offer lower participation fees for developers. Those lower fees increase network benefits for consumers, allowing the platforms to exploit these benefits through personalized pricing. Personalized prices are higher when the network value for developers is high, benefiting competing platforms at the expense of consumers. These findings offer policy insights on personalized pricing.
