摘要

我们研究了向下游企业出售消费者数据的数据经纪人（DB）的存在如何影响横向差异化寡头垄断市场中的企业进入和竞争，在该市场中，数据允许企业进行价格歧视。数据库商可以选择向每家公司出售数据的价格和数量。我们的研究表明，数据中心的数据销售减少了过度的市场进入，因为个性化价格引起的竞争对价格和利润产生了向下的压力。由数据引发的市场进入壁垒和由此导致的竞争弱化主导了个性化价格的促进竞争效应。因此，虽然设计公司的存在可能会缓解过度进入市场的现象，但也会减少消费者剩余。

User Data and Endogenous Entry in Online Markets*

We investigate how the presence of a Data Broker (DB), who sells consumer data to downstream firms, affects firm entry and competition in a horizontally differentiated oligopoly market, in which data allow firms to price discriminate. The DB chooses the price and amount of data sold to each firm. We show that the data sale by the DB reduces excessive market entry, as the competition induced by personalized prices exerts a downward pressure on prices and profits. The data-induced entry barrier and resulting weakened competition dominates the pro-competitive effect of personalized prices. Consequently, while the DB's presence might alleviate excessive market entry, it also diminishes consumer surplus.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
