报告内容简介：

Recently, a controversial new privacy policy on the mobile app platform, which requires app developers to display privacy labels and explicitly request data-tracking permissions from users, has sparked a heated discussion among practitioners in digital advertising. In this paper, we build a game-theoretic model to examine how this new policy impacts the key stakeholders of a mobile app platform (i.e., app developers, the platform, and consumers). The model captures how the new policy prompts developers to broaden their strategies beyond mere pricing competition by incorporating data-tracking levels as an additional competitive dimension, which in turn impacts the intensity of price competition among developers. We find that while implementing a policy that restricts developers’ tracking of consumers may lead to an increase in advertising revenue for the platform, it can sometimes put the platform at a disadvantage. This is because it may incentivize developers to lower their prices and engage in more intense price competition, consequently reducing the platform’s commission revenue. Regarding app developers, the new policy may prove beneficial, despite its restriction to tracking only those consumers who have opted in. Another noteworthy finding is that while platforms have asserted that the new policy is aimed at safeguarding consumers’ privacy, it does not always serve consumers’ best interests. Our paper provides meaningful implications for all key stakeholders within the realm of mobile app platforms regarding the implementation of the new privacy policy.
