论文摘要：This paper proposes a framework in which two platforms compete to improve their targetability, which sensitizes consumers to privacy concern and leads them to resist ads. We analyze the impact of consumer privacy on competitive pursuit of targetability by the platforms. We find that, underpay-TV, equilibrium targetability is lower than the social optimum. The improvement in targetability hurts platforms but benefits consumers. Under free-to-air, equilibrium targetabilityis too high (low) if consumers are more (less) privacy-sensitive, increased targetability might benefit both platforms and consumers. In addition, privacy regulation reduces targeting accuracy through the increase in the cost of improving targetability and therefore might make consumers worse off. Our findings contribute to the business strategy of platforms and offer insights to the assessment of the regulatory debate on consumer privacy.
