4.1 Infinitely Repeated Game

Repeated Game

A repeated game is an extensive form game that consists of one strategic form stage game $n$ times. If $n$ has no fixed end, the repeated game never ends, and is therefore an infinitely repeated game.

Example

Rationale for Infinite Repetition

(Equilibria) If there is a stage-game Nash equilibrium, then that Nash equilibrium is an SPNE for the repeated game.
