Zusammenfassung:
This paper studies how commission rates affect app entry across platforms. We examine an increase in Android game commission rate from 30% to 50% in China in 2014 and its impact on Android and iOS app stores, separately, in a difference-in-differences framework. We find a direct negative entry effect on Android by 47%. Meanwhile, the number of new games on the iOS App Store significantly decreased by 30% due to the higher Android commission rate, implying a negative cross-platform spillover effect. Moreover, the share of high-quality new games significantly decreased by 12%, indicating that higher commission rates discourage developers’ quality provision.
