We introduce a tractable model of cheap talk among players located on networks. In our model, a player can send a message to another player if and only if he is linked to him. We derive a sharp equilibrium and welfare characterization which reveals two basic insights. In equilibrium, the...

We study a model of multi-player communication. Privately informed decision makers have different preferences about the actions they take, and communicate to influence each othersʼ actions in their favor. We prove that the equilibrium capability of any player to send a truthful message to a set...
