数据中介从个人消费者那里获取有关其偏好的信号。中间商在产品市场上转售信息，企业和消费者根据需求数据调整他们的选择。个人数据的社会维度——即消费者的数据可以预测他人的行为——产生了一种数据外部性，可以降低中间商获取信息的成本。当且仅当这样做会增加社会剩余时，中介才能最优地保护消费者身份的隐私。该策略使中介机构能够在消费者数量增加时获取信息的总价值。
A data intermediary acquires signals from individual consumers regarding their preferences. The intermediary resells the information in a product market wherein firms and consumers tailor their choices to the demand data. The social dimension of the individual data—whereby a consumer's data are predictive of others' behavior—generates a data externality that can reduce the intermediary's cost of acquiring the information. The intermediary optimally preserves the privacy of consumers' identities if and only if doing so increases social surplus. This policy enables the intermediary to capture the total value of the information as the number of consumers becomes large.
