We present a novel theoretical mechanism that explains the capacity for non-enforceable communication about future actions to improve efficiency. We explore a two-player partnership game where, before choosing a level of effort to exert on a joint project, each player makes a cheap talk promise...

Our understanding of risk preferences can be sharpened by considering their evolutionary basis. Recently, Robatto and Szentes (2017) found that both aggregate risk and idiosyncratic risk generate the same growth rate in a continuous time setting. We introduce a new source of risk, which is...

This paper analyzes the implementation of correlated equilibria that are immune to joint deviations of coalitions by cheap-talk protocols. We construct a cheap-talk protocol that is resistant to deviations of fewer than half the players, and using it, we show that a large set of correlated...

A strong correlated equilibrium is a correlated strategy profile that is immune to joint deviations. Different notions of strong correlated equilibria have been defined in the literature. One major difference among those definitions is the stage in which coalitions can plan a joint deviation:...

In many situations a decision maker has incomplete psychological preferences, and the weak axiom of revealed preference (WARP) is often violated. In this paper we relax WARP, and replace it with convex axiom of revealed non-inferiority (CARNI). An alternative x is revealed inferior to y if x is...

We prove that every undiscounted multi-player stopping game in discrete time admits an approximate correlated equilibrium. Moreover, the equilibrium has five appealing properties: (1) “Trembling-hand” perfectness - players do not use non-credible threats; (2) Normal-form correlation -...
