内容摘要：In this paper, we study platforms' information acquisition incentive and pricing strategy in a two-sided duopoly market. In stage 1, each platform decides whether to acquire information regarding consumers' preferences, which are characterized by the location of the consumer in a Hotelling setting. If a platform decides not to acquire information, its pricing strategy in the next stage will be uniform pricing. If a platform decides to acquire information, it can adopt a third-degree price discrimination, based on the acquired information, whose precision measured by the information partition is exogenously given. In stage 2, both platforms set their own prices based on the type of the pricing strategy. We characterize the equilibrium of the game, and show how precision of information affects platforms' incentive of information acquisition and the equilibrium outcome. We also conduct welfare analysis.
