Essays on Information Economics
 Matysková, Ludmila ; Steiner, Jakub (advisor) ; Kamenica, Emir (referee) ; Dean, Mark (referee)
In the first chapter, we study the effect on the economy of platforms for online consumer reviews. Consumer reviews may have perverse effects, including delays in the adoption of new products of unknown quality when consumers are boundedly rational. When consumers fail to take into account that past reviewers self-select into purchases, a monopolist may manipulate the posterior beliefs of consumers who observe the reviews, because the product price determines the self-selection bias. The monopolist will charge a relatively high price because the positive selection of the early adopters increases the quality reported in the reviews. In the second chapter, we study a game between a sender and a receiver in a framework of Bayesian persuasion. A sender choosing a signal to be disclosed to a receiver can often influence the receiver's actions. Is persuasion more difficult when the receiver has additional information sources? Does the receiver benefit from having the additional sources? We extend a Bayesian persuasion model to a receiver's acquisition of costly information. The game can be solved as a standard Bayesian persuasion model under an additional constraint: the receiver never gathers her own costly information. The `threat' of learning hurts the sender. However, the resulting outcome can also...
