We analyze how a privacy regulation taking the form of a cap on information disclosure affects quality-enhancing innovation incentives by a monopolist--who derives revenues solely from disclosing user data to third parties--and consumer surplus. If the share of privacy-concerned users is sufficiently small, privacy regulation has a negative effect on innovation and may harm users. However, if the share of privacy-concerned users is sufficiently large, privacy regulation has a positive effect on innovation. In this case, there is no trade-off between privacy and innovation and users always benefit from privacy regulation.
