<br/><br/> This paper investigates robust information transmission between a sender and a receiver in the Crawford and Sobel (1982) model. We characterize behavior that remains equilibrium behavior independently of the form of a small communication cost. Under standard conditions, we find that an equilibrium outcome is robust if and only if it features a maximal number of on-path actions and each is induced by a single message. The result extends regardless of the direction of the bias, the number of available messages, or whether the objectives of the sender and the receiver are aligned.- Reproduced
