Abstract: Much of the recent literature on information design in two-sided platforms focuses on the role of information disclosure in influencing demand-side decisions. This paper focuses instead on the interaction between information design and supply-side decisions, including supplier entry/exit and pricing. We develop a dynamic model of a two-sided platform that allows us to analyze the long-run implications of alternative information-disclosure policies. Our analysis highlights three main mechanisms through which such a policy improves platform revenues: (i) in cases where the platform is dominant in the market, a downgrading policy helps the platform modulate the composition of suppliers active on the platform, leading to an overall more revenue-efficient set of suppliers; (ii) in cases where the platform is not dominant in the market, a downgrading policy increases the volume of transactions on the platform and, surprisingly, may also result in an increase in the volume of high-quality providers active in the platform; (iii) when commission subsidies are used by the platform to incentivize entry of new providers, a downgrading policy helps the platform achieve equivalent new-provider entry while extracting higher revenue per transaction
