Biased Recommendations and Differentially Informed Consumers

Abstract

We consider a monopolist selling an experience good to differentially informed consumers: some consumers are uncertain about their tastes, whereas other consumers are perfectly informed. The fully informed monopolist sets a uniform price and can make personalized product recommendations. We characterize conditions under which the monopolist biases its recommendations – that is, some consumers with match values lower than the marginal cost follow the recommendation to buy the product or some consumers with match values higher than the marginal cost follow the recommendation not to buy the product.
