Until recently, theorists considering the evolution of human cooperation have paid little attention to institutional … maximize compliance? We investigate this question by modeling the co-evolution of law and cooperation in a public goods game … punishment, a defining feature of large-scale human societies. Compared to individually-administered punishment, institutional …

We study a population comprised of "thick-skinned" and "thin-skinned" agents by using an indirect … evolution model that combines rational choice in strategic interactions with evolutionary selection across generations. We find … ways in which rationality hinders the evolution of the relatively vulnerable and peaceful type of agent …
