Key Concepts

Infinitely Repeated Games

These are games that are played over an unlimited number of periods, allowing players to adjust their strategies based on past actions. The presence of an infinite horizon means that the future can be leveraged to enforce cooperative behavior today, because any deviation or short-term gain may lead to long-term punishment that outweighs the immediate benefit.

Folk Theorem

This result in game theory suggests that if the game is infinitely repeated and players are sufficiently patient, a wide variety of outcomes, including cooperative and collusive equilibria, can be sustained as subgame perfect equilibria. It underlines that the threat of future punishment can deter players from deviating from a cooperative agreement.

Trigger Strategies

Trigger strategies are a class of contingent strategies in repeated games where a player cooperates until the opponent deviates, after which the player enacts a punishment strategy (often reverting permanently to a non-cooperative equilibrium). This credible threat of future punishment helps maintain cooperation between players.

Collusion in Repeated Interactions

In the context of repeated games, firms or players may tacitly agree to a mutually beneficial outcome, such as higher pricing in an oligopoly. Collusion is supported by the ability to impose future punishments on defectors, ensuring that sticking to the collusive agreement is more beneficial in the long run compared to short-term deviation.
