We study the success of generalised trigger strategies in the evolution of cooperation in international environmental negotiations where the performance of these strategies is derived from asymmetric n-player prisoners’ dilemmas. Our results suggest that there exist regions in the relevant parameter space—i.e. costs and benefits, low and high tit-for-tat thresholds, probability of continued interaction—such that (partial) cooperation may emerge as long-run attractor of the evolutionary dynamics in these asymmetric social dilemmas.
