We study a principal-agent model. The parties are symmetrically informed at first; the principal then designs the process by which the agent learns his type and, concurrently, the screening mechanism. Because the agent can opt out of the mechanism ex post, it must leave him with nonnegative...

This paper studies the general information disclosure model (Grossman, 1981; Milgrom, 1981) relaxing the assumption of monotonicity in preferences. I apply the belief-based approach, which is developed in Bayesian persuasion (Kamenica and Gentzkow, 2011) and applied to cheap talk (Lipnowski and...

We study a multi-player model of sequential communication. A receiver obtains information from two sources. The first is cheap talk with a sender, who acquires the information, while the second is Bayesian persuasion with a mediator, who modifies the initial information. We prove that Bayesian...

This paper analyses the equilibrium and welfare properties of an economy characterized by uncertainty and payoff externalities using a general model that nests several applications. Agents receive a private signal and an endogenous public signal, which is a noisy aggregate of individual actions...

This paper studies stylised markets with asymmetric information. When the market is modelled as a standard signalling game, inefficient outcomes arise due to the arbitrariness of off-the-equilibrium path beliefs. Such inefficient outcomes are shown not to arise in a novel game that combines...

We study costly augmentation of signal accuracy by the principal in a binary model, with two-dimensional signal quality. Irrespective of cost, the outcomes when the principal can pre-commit to precision levels differ significantly from those when she cannot

In a market environment with random detection of product quality, a firm can employ umbrella branding as a strategy to convince consumers of the high quality of its products. Alternatively, a firm can rely on external certification of the quality of one or both of its products. We characterize...

This paper studies sequential Bayesian persuasion games with multiple senders. We provide a tractable characterization of equilibrium outcomes. We apply the model to study how the structure of consultations affects information revelation. Adding a sender who moves first cannot reduce...
