【内容摘要】
This paper studies consumers’ incentives to hide their purchase histories when the seller’s prices depend on previous behavior. Through distinct channels, hiding both hinders and facilitates trade.
Indeed, the social optimum involves hiding to some extent, yet not fully. Two opposing effects determine whether a consumer hides too much or too little:the first-period social gains are only partially internalized, and there is a private (socially irrelevant) second-period gain due to price differences. If the discount factor is large, the second effect dominates and there is socially excessive hiding. This result is reversed if the discount factor is small.
