WebFolk theorem (game theory) In game theory, folk theorems are a class of theorems which imply that in repeated games, any outcome is a feasible solution concept, if under that outcome the players' minimax conditions are satisfied. The minimax condition states that a player will minimize the maximum possible loss which they could face in the game. WebThe infinitely repeated game, in which each player attempts to maximize his discounted payoff. For each of these models we prove a Folk Theorem, which states that under some technical conditions the set of equilibrium payoffs is (or approximates) the set of feasible and individually rational payoffs of the base game.

In game theory, folk theorems are a class of theorems about possible Nash equilibrium payoff profiles in repeated games ( Friedman 1971 ).

In game theory, folk theorems are a class of theorems describing an abundance of 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.
