We model couples decisions as a noncooperative game and solve for a Markov Perfect Equilibrium (MPE) in pure strategies. Econometrica, 69(5):1261{1281. As a corollary to Theorem 1, we know that a stationary Markov perfect equilibrium exists in a stochastic game with endogenous shocks. This lecture describes the concept of Markov perfect equilibrium. Readings: Hausman, Jerry, “Valuation of New Goods Under Perfect and Imperfect Competition,” in Bresnahan and Gordon (eds. In Bayesian learning, each player again acts to maximize discounted payoffs or average payoffs; however, it is assumed that players are not certain about the strategies of their opponents.

Markov perfect equilibrium is a key notion for analyzing economic problems involving dy-namic strategic interaction, and a cornerstone of applied game theory.

Peace war game is an iterated game originally played in academic groups and by computer simulation for years to study possible strategies of cooperation and aggression. (SPE doesn’t suer from this problem in the context of a bargaining game, but many other games -especially repeated games- contain a large number of SPE.)
