ABSTRACT: We present a general and tractable oligopoly model of multi-sided platforms that accommodate both endogenous side and platform choices of heterogeneous end-users. These features are considered for single- and multi-homing platforms and assume that participation on one side could preclude doing so on others. We show the existence and uniqueness of the equilibrium number of end-users and derive platforms’ optimal prices. Using the equilibrium conditions, we formally characterize a set of the novel (across sides and platforms) switching effects that distort the optimal pricing of platforms, leading in some cases to markups greater than the usual Lerner index, and that rule out the classical “cross-subsidization” result. The characterization of these novel effects allows us to provide a unifying framework to analyze mergers of multi-sided platforms, which rationalizes mixed results in the previous literature. While the nature of end-users‘ side choices determines optimal pricing, their platform choices are crucial for merger analysis.
