Communication on networks and strong reliability
Résumé
We consider sender-receiver games, where the sender and the receiver are two distant nodes on a communication network. We show that if the network has two disjoint paths of communication between the sender and the receiver, then we can replicate not only all equilibrium outcomes of the direct communication game (i.e., when the sender and the receiver communicate directly with each other), but also of the mediated game (i.e., when the sender and the receiver communicate with the help of a mediator).
