Competition in Persuasion
We study the impact of competition on information revelation in a class of Bayesian Persuasion games with multiple senders. Senders with no private information choose what information to gather and communicate to a receiver who takes a non-contractible action that affects the welfare of all players. The space of available signals includes all possible conditional distributions and allows any sender to choose a signal that is arbitrarily correlated with signals of others. We characterize the information revealed in pure-strategy equilibria, and show that greater competition tends to increase the amount of information revealed.
