The Tension Between Market Shares and Profit Under Platform Competition

Abstract

We introduce asymmetries across platforms in the linear model of competing two-sided platforms with singlehoming on both sides and fully characterize the price equilibrium. We identify market environments in which one platform has a larger market share on both sides while obtaining a lower profit than the other platform. This platform enjoys a competitive advantage on one or both sides. Our finding raises further doubts on using market shares as a measure of market power in platform markets.
