Cheap Talk with an Informed Receiver
This paper examines the effectiveness of cheap talk when the receiver is imperfectly informed. We show that the receiver's prior knowledge becomes an impediment to efficient communication in a model with the discrete state space: in general, the more the receiver is informed, the less information she can extract from the sender. In fact, when the receiver is as informed as the sender, no information can be conveyed via cheap talk for an arbitrarily small preference bias. This draws sharp contrast to the conventional setup where there is always a fully separating equilibrium as long as the preference bias is sufficiently small. We relate this result to issues that are critical for organizational design, such as the allocation of decision-making authority and the span of control.
