We consider the equilibrium interplay between sellers’ price competition and consumers’ perception of product differentiation. We analyze a situation where, before trading, consumers acquire information at a cost about their preferences between sellers’ differentiated products. The incentive for information acquisition depends on the average value of products, the objective product differentiation, and their beliefs about sellers’ prices. The acquired information shapes consumers’ perceived product differentiation and sellers’ equilibrium prices. We characterize the unique symmetric equilibrium and study comparative statics with respect to consumer information acquisition cost and sensitivity to product differentiation. We then apply our model to platform design.
本文考虑了卖家的价格竞争与消费者对产品差异化感知之间的均衡互动。本文分析了一种情况，在交易之前，消费者会以一定的成本获取关于他们对卖家差异化产品偏好的信息。获取信息的激励取决于产品的平均价值、客观的产品差异化以及他们对卖家价格的信念。获取的信息塑造了消费者对产品差异化的感知以及卖家的均衡价格。本文描述了唯一的对称均衡，并研究了与消费者信息获取成本和对产品差异化敏感度相关的比较静态分析。然后将模型应用于平台设计。
