中文摘要
本文在消费者具有隐私意识的情形下评估隐私监管的有效性。我们构建了一个数据链接模型，其中消费者依次与两家企业互动：一家企业收集消费者行为数据，另一家企业利用该数据设定质量水平和价格。在均衡中，当接收数据的企业与收集数据的企业足够相似时，数据链接会使消费者受益。我们在若干现行隐私监管规则下将链接形成内生化。自愿同意要求在均衡中使消费者受益，而全面禁止歧视性价格与质量报价则损害消费者利益。(JEL D11, D21, D82, D83)
Abstract
We assess the efficacy of privacy regulation when consumers are privacy conscious. We develop a model of data linkages where a consumer interacts sequentially with two firms: One firm collects data on consumer behavior, and the other firm leverages the data to set a quality level and a price. A data linkage benefits the consumer in equilibrium when the recipient firm is sufficiently similar to the collecting firm. We endogenize linkage formation under several existing privacy regulations. Voluntary consent requirements benefit consumers in equilibrium, but blanket bans on discriminatory price and quality offers harm them. (JEL D11, D21, D82, D83)
