Consumer Privacy and the Market for Customer Information
研究电子零售中客户信息的价值，分析保密与披露两种制度下信息销售对定价和福利的影响，关键取决于消费者预期和需求弹性。
I investigate consumer privacy and the market for customer information in electronic retailing. The value of customer information derives from the ability of Internet firms to identify individual consumers and charge them personalized prices. I study two settings, a confidential regime in which the sale of customer information is not possible, and a disclosure regime in which one firm may compile and sell a customer list to another firm that uses it to price discriminate. Welfare comparisons depend critically on whether consumers anticipate sale of the list and on demand elasticity.
