dc.titleStrategic information transmission with sender’s approval: the single crossing case
dc.typeDocument de travail / Working paper
dc.description.abstractenWe consider a sender-receiver game, in which the sender has finitely many types and the receiver’s decision is a real number. We assume that utility functions are concave, single-peaked and single-crossing. After the cheap talk phase, the receiver makes a decision, which requires the sender’s approval to be implemented. Otherwise, the sender “exits”. At a perfect Bayesian equilibrium without exit, the receiver must maximize his expected utility subject to the participation constraints of all positive probability types.This necessary condition may not hold at the receiver’s prior belief, so that a non-revealing equilibrium may fail to exist. Similarly, a fully revealing equilibrium may not exist either due to the sender’s incentive compatibility conditions. We propose a constructive algorithm that always achieves a perfect Bayesian equilibrium without exit.
