We study a hierarchical Bayesian persuasion game with a sender, a receiver, and several potential intermediaries, generalizing the framework of Kamenica and Gentzkow (2011). The sender must be persuasive through a hierarchy of intermediaries to reach the final receiver, whose action affects all...

We study the dominant separating equilibrium that maximizes the sender's payoff in quadratic signaling games. We relax the common and restrictive belief monotonicity assumption. We introduce a game characteristic called discriminant and show that there exists a linear incentive compatible...
