To illustrate those insights, we develop a simple model in which two-sided platforms offer a homogeneous service and compete à la Cournot, and derive the effects of "average-marginal-cost-preserving" mergers on consumers on both sides of the market. We conclude with a discussion of several research avenues that could be explored to understand better the impact of horizontal mergers between multi-sided platforms.
