Punishing and abstaining for public goods.
The evolution of cooperation within sizable groups of nonrelated humans offers many challenges for our understanding. Current research has highlighted two factors boosting cooperation in public goods interactions, namely, costly punishment of defectors and the option to abstain from the joint enterprise. A recent modeling approach has suggested that the autarkic option acts as a catalyzer for t...
متن کاملPublic goods with punishment and abstaining in finite and infinite populations.
The evolution and maintenance of cooperation in human and animal societies challenges various disciplines ranging from evolutionary biology, to anthropology, social sciences and economics. In social interactions, cooperators increase the welfare of the group at some cost to themselves whereas defectors attempt to free-ride and neither provide benefits nor incur costs. The problem of cooperation...
متن کاملCompetition and cooperation among different punishing strategies in the spatial public goods game
Inspired by the fact that people have diverse propensities to punish wrongdoers, we study a spatial public goods game with defectors and different types of punishing cooperators. During the game, cooperators punish defectors with class-specific probabilities and subsequently share the associated costs of sanctioning. We show that in the presence of different punishing cooperators the highest le...

Punishing Free-Riders: How Group Size Affects Mutual Monitoring and the Provision of Public Goods Because costly punishment is not credible, subgame perfection suggests that punishment will not deter free riding, regardless of the size or structure of groups. However, experiments show that people will punish free riders, even at considerable cost. To examine the implications of agents who punis...

I argue that we should reclaim the more traditional conception of public health as the provision of health-related public goods. The public goods account has the advantage of establishing a relatively clear and distinctive mission for public health. It ...
