Abstract

We study how switching costs affect the sub-game perfect equilibria in repeated games. We show that (i) the Folk Theorem holds whenever the players are patient enough; (ii) the set of equilibrium payoffs is obtained by considering the payoffs of a simple one-shot auxiliary game; and (iii) the switching costs have a negative impact on a player in the infinitely undiscounted repeated game but can be beneficial for him in a finitely repeated game or in a discounted game.
