Abstract:
We study compatibility decisions of two competing platforms that generate profits through both hardware sales and royalties from content sales. We consider a game-theoretic model in which the platform hardware may offer different standalone utilities to users who have different preferences over the two platforms. We find that incentives to establish one-way compatibility---the platform with smaller standalone value allows users of the competing platform to access its content---can arise from the difference in their profit foci. As the difference in the standalone utilities increases, royalties from content sales become less important to the platform with greater standalone value but becomes more important for the other platform. Compatibility can thus increase asymmetry between the platforms' profit foci and, when the difference in the standalone utilities is sufficiently large, yields greater profits for both platforms. We further show that social welfare is greater under one-way compatibility than under incompatibility, and there exist no incentives for either platform to establish one-way compatibility the other way round---the platform with greater standalone value allows users of the competing platform to access its content. We investigate as well how factors such as platform production costs, exclusive content, heterogeneous intensities of content consumption, endogenized royalty rates, and correlation in consumer preferences for hardware and software affect compatibility incentives.
