许多电子商务平台使用买家的个人数据来中介他们与卖家的交易。这些中介机构从每个人的数据记录中获得了多少价值？我们描述了这个值，并发现它的关键组成部分之一是一个新的外部性记录之间，当中介池的一些记录，以保留它们所包含的信息。我们的分析对补偿个人使用其数据，指导公司在数据获取方面的投资以及更广泛地研究数据市场的需求方面有几个影响。我们的方法结合了联合收割机现代信息设计与经典的对偶理论，并适用于一个大类的委托代理问题。
Many e-commerce platforms use buyers’ personal data to intermediate their transactions with sellers. How much value do such intermediaries derive from the data record of each single individual? We characterize this value and find that one of its key components is a novel externality between records, which arises when the intermediary pools some records to withhold the information they contain. Our analysis has several implications about compensating individuals for the use of their data, guiding companies’ investments in data acquisition, and more broadly studying the demand side of data markets. Our methods combine modern information design with classic duality theory and apply to a large class of principal-agent problems.
