We study how different types of information revealed by reviews affect the retailer under the wholesale scheme and platform scheme. We find that information provided by reviews on quality dimension homogenizes consumers’ perceived utility differences between products and increases upstream competition, which benefits the retailer under the wholesale scheme but hurts the retailer under the platform scheme. Information provided by reviews on fit dimension heterogenizes consumers’ estimated fits to products and softens upstream competition, which hurts the retailer under the wholesale scheme and benefits the retailer under the platform scheme. Together, we demonstrate that the quality information and fit information play very different roles in changing upstream competition, and whether the retailer benefits from reviews critically depends on its pricing scheme choice.
