We find that contrary to common perception, cooperation as equilibrium of the infinitely repeated discounted prisoner's dilemma is in many relevant cases not very plausible, or at least questionable: for a significant subset of the payoff-discount factor parameter space cooperation equilibria are strictly risk dominated by non-cooperation (according to the Harsanyi-Selten 1988 criterion). Examples include collusion equilibria in the repeated Cournot duopoly.
