Competitive information disclosure by multiple senders

Abstract

We analyze a model of competition in Bayesian persuasion in which multiple symmetric senders vie for the patronage of a receiver by disclosing information about their respective proposal qualities. We show that a symmetric equilibrium exists and is unique. We then show that as the number of senders increases, each sender discloses information more aggressively, and full disclosure by each sender arises in the limit of infinitely many senders.
