In International Relations the canonical model of inter-estate interactions is a one-shot security competition game. The model has the structure of a prisoners dilemma, which results in an equilibrium with two sources of inefficiency: excessive arming and possibly the destruction associated with...

We study sequential equilibrium payoffs of a repeated game with local interaction and local monitoring. An undirected network determines both the interaction and the monitoring structure. When players do not discount the future, a sequentially rational Nash threats folk theorem holds without any...

We propose an extension to smooth fictitious play and prove that play converges to an ε-Markov perfect equilibrium with probability one in a class of stochastic games known as Markov potential games. We then prove a partial Folk theorem for repeated games under one-period perfect monitoring. We...
