WitrynaTheorem 1 (A One-Shot Folk Theorem) Let Γbe a homogeneous product Bertrand game in which limp→pMπ(p) →∞.Then any k∈[0,∞) may be achieved as the ex-pected per firm profits in a symmetric mixed-strategy Nash equilibrium of Γ. Proof. Since π(p) is a strictly increasing, continuous function on [p∗,pM), it follows Witryna"A complete folk theorem for finitely repeated games," Center for Mathematical Economics Working Papers 584, Center for Mathematical Economics, Bielefeld University.

WitrynaNash equilibria of the stage-game.1 Smith (1995) provided a weaker, necessary and sufficient condition for the limit perfect folk theorem to hold. Smith (1995)showed that it is necessary and sufficient that the Nash decomposition of the stage-game is complete.2 The distinct Nash payoffs condition and the full dimensionality of the WitrynaIn game theory, folk theorems are a class of theorems about possible Nash equilibrium payoff profiles in repeated games (Friedman 1971). The original Folk Theorem concerned the payoffs of all the Nash equilibria of an infinitely repeated game. This result was called the Folk Theorem because it was widely known among game theorists in …
WitrynaFolk Theorem Theorem (Folk Theorem) Consider any n-player game G and any payoff vector (r 1,r 2,...,r n). 1 If r is the payoff in any Nash equilibrium of the infinitely repeated G with average rewards, then for each player i, r i is enforceable. 2 If r is both feasible and enforceable, then r is the payoff in Witrynareward, as I later provide a necessary and sufficient condition for the finite-horizon Nash folk theorem. I also recast BK in Wen's more encompassing framework.3 In so doing, I happen upon a simple new proof of the necessity of NEU in Abreu et al. (1994), and of what "necessity" means in Wen's tiered "folk" theorems more generally.

WitrynaThere are many well-known strategies that are used to take advantage of the Folk theorems, such as Nash reversion, tit-for-tat, grim trigger or forgiving strategies [18,27]. All these strategies agree on a strategy that all players should follow and a punishment strategy which arises if any of the players deviate from the agreed strategy.
