Abstract

We study monotone persuasion in the linear case, where a posterior distribution over states is summarized by its mean. We identify two settings where the optimal unrestricted signal can be nonmonotone. In the first setting, the optimal unrestricted signal requires randomization. In the second setting, the optimal unrestricted signal entails nonmonotone pooling of states. We solve for the optimal monotone signal in each setting, and illustrate our results with an application to media censorship.
