Refining Cheap - Talk Equilibria *
Several conceptual points are made concerning communication in games of asymmetric information. Equilibrium refinements of Sender-Receiver cheap-talk games that are based on the concept of a putative equilibrium, and which rely on the presence of a rich language with literal meanings, are discussed. Three nested criteria are proposed: strong announcement-proofness, announcement-proofness, and w...

متن کاملSelecting Cheap-Talk Equilibria∗
There are typically multiple equilibrium outcomes in the Crawford-Sobel (CS) model of strategic information transmission. This paper identifies a simple condition on equilibrium payoffs, called NITS, that selects among CS equilibria. Under a commonly used regularity condition, only the equilibrium with the maximal number of induced actions satisfies NITS. We discuss various justifications for N...
متن کاملDurable Cheap Talk Equilibria∗
We consider a cheap-talk game with one sender and one receiver. If the receiver does not commit to listen to only one message, the equilibrium refinements due to Farrell [5], Grossman and Perry [7] and Matthews, OkunoFujiwara and Postlewaite [11] are no longer applicable. We discuss different notions of durability and sequential credibility when a message can later be followed by more messages,...
متن کاملRobust almost fully revealing equilibria in multi-sender cheap talk∗
This paper shows that in multi-sender cheap talk games, if the state space is large enough, then there exist equilibria arbitrarily close to full revelation of the state that are robust to introducing a small amount of noise in the senders’ observations. The result holds irrespectively of the dimensionality of the state space, including for one-dimensional state spaces. We establish the result ...
