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 (no incentive to separate), that selects among CS equilibria. Under a commonly used regularity...

We add a round of pre-play communication to a finite two-player game played by a population of players. Pre-play communication is cheap talk in the sense that it does not directly enter the payoffs. The paper characterizes the set of strategies that are stable with respect to a stochastic...

A dynamic monopolist produces at constant unit cost. Each period a new cohort of consumers enters the market. Each entering cohort is identical. Consumers within a cohort have different tastes. The paper shows that if players are sufficiently patient, any positive average profit less than the...

The authors introduce a new solution concept, divine equilibrium, which refines the set of sequential equilibria in signaling games by requiring that off-the-equilibrium-path beliefs satisfy an additional restriction. This restriction rules out implausible sequential equilibria in examples....
