Topic

Product recommendations and price parity clauses (Martin Peitz and Anton Sobolev) 

abstract

A seller can offer an experience good directly to consumers and indirectly through an intermediary. When selling indirectly, the intermediary provides recommendations based on the consumer’s match value and the prices at which the product is sold. The intermediary faces the trade-off between extracting rents from consumers who strongly care about the match value versus providing less informative recommendations but also serving consumers who do not. We analyze the allocative and welfare effects of prohibiting price parity clauses and/or regulating the intermediary’s recommendersystem. Prohibiting price parity clauses is always welfare decreasing in our model.
