abstract: this paper studies how the provision of product and/or market information affects the behavior of buyers and sellers and the sales volume of online markets. we first identify the pareto-efficient equilibrium of the seller's pricing decision. then, under different information structures, we study the impact of market parameters on platform sales volume at equilibrium. we find that platform sales volume increases with the size of potential buyers, but varies non-monotonically with the size of potential sellers. next, we analyze the platform's optimal information strategy. we find that while it is always optimal for the platform to disclose certain information, it should strategically disclose information in the face of different supply-demand conditions. specifically, in a seller's market (where the proportion of potential buyers and sellers is high), the platform should provide product and market information to both sellers and buyers. however, in a buyer's market (where the proportion of potential buyers to sellers is low), the platform is best to only provide market information.
