We study the role of communication in repeated games with private monitoring. We first show that without communication, the set of Nash equilibrium payoffs in such games is a subset of the set of ε-coarse correlated equilibrium payoffs (ε-CCE) of the underlying one-shot game. The value of...

We study the role of communication in repeated games with private monitoring. We first show that without communication, the set of Nash equilibrium payoffs in such games is a subset of the set ofε‐coarse correlated equilibrium payoffs (ε‐CCE) of the underlying one‐shot game. The value...

We study the role of communication in repeated games with private monitoring. In such games, players receive only noisy private signals about each other's actions. For a fixed discount factor, we identify conditions under which there are equilibria with "cheap talk" that result in nearly...

Antitrust authorities view the exchange of detailed information among firms regarding costs, prices or sales as being potentially anti-competitive. The reason is that such exchanges may allow competitors to closely monitor each other, thereby facilitating greater coordination. But the exchange...

We study a continuous-time R&D race between an established firm and a startup under asymmetric information. R&D investment brings success stochastically but only if the innovation is feasible. The only asymmetry between the firms is that the established firm has better information about the...

Rumors of a shortage may create higher-order uncertainty and cause panic buying even when there is no real shortage and most consumers are aware of this fact. We study the role of prices in alleviating, or even preventing, panic buying caused by such rumors. Under some circumstances, flexible...
