Prosocial punishment has been proved to be a powerful mean to promote cooperation. Recent studies have found that social exclusion, which indeed can be regarded as a kind of punishment, can also support cooperation. However, if prosocial punishment and exclusion are both present, it is still unclear which strategy is more advantageous to curb free-riders. Here we first study the direct competition between different types of punishment and exclusion. We find that pool (peer) exclusion can always… 
Competitions between social exclusions and rewards in the optional public goods game
The emergence of cooperative behavior is fundamental for a society to thrive. Some experimental studies have showed that reward outperforms punishment in repeated public goods games. On the other
Evolutionary dynamics in the public goods games with switching between punishment and exclusion
TLDR
It is shown that an intermediate value of the threshold leads to a stable coexistence of cooperators, defectors, and players adopting the switching strategy in a well-mixed population, and this regardless of whether the pool-based or the peer-based switching strategy is introduced.
Evolutionary dynamics of cooperation in the public goods game with pool exclusion strategies
Social exclusion is widely used as a control mechanism to promote cooperative behavior in human societies. However, it remains unclear how such control strategies actually influence the evolutionary
Evolutionary Dynamics of Cooperation in the Public Goods Game with Individual Disguise and Peer Punishment
TLDR
In infinite populations, by using replicator equations, it is found that although low disguise cost can hinder public cooperation, peer punishment still plays a positive role in promoting the evolution of cooperation, no matter whether second-order punishment is considered or not.
A switching strategy between costly punishment and exclusion for the evolution of cooperation
Social exclusion and costly punishment have been regarded as potential measures to solve the conundrum of cooperation recently. In real life, what is pretty widespread is the combined use of multiple
Early exclusion leads to cyclical cooperation in repeated group interactions
Explaining the emergence and maintenance of cooperation among selfish individuals from an evolutionary perspective remains a grand challenge in biology, economy and social sciences. Social exclusion
The evolution of cooperation in spatial public goods game with conditional peer exclusion.
TLDR
Simulation results confirmed that conditional exclusion can greatly reduce the threshold values of the synergy factor above which cooperation can emerge and allow us to better understand the role of exclusion strategies in the emergence of cooperation.
Evolution of cooperation driven by individual disguise in the public goods game with pool punishment
The phenomenon of individual disguise is pervasive in the real world. But in theory it is unclear what roles it plays in the evolution of cooperation. In this work we introduce individual disguise
The Effect of Inequity Aversion Driven Punishment on Cooperation
Unlike in the traditional punishment mechanism, punishers driven by inequity aversion punish individuals who have a higher payoff, rather than those who adopt a certain strategy, and the intensity of

The evolution of cooperation by social exclusion
TLDR
This work presents a game-theoretical model of social exclusion in which a punishing cooperator can exclude freeriders from benefit sharing and shows that such social exclusion can overcome the above-mentioned difficulties even if it is costly and stochastic.
Social exclusion in finite populations.
TLDR
This work proposes two different exclusion regimes, namely, peer exclusion and pool exclusion, to investigate the evolution of social exclusion in finite populations, and indicates that the group exclusion mechanism helps the cooperative union to survive under unfavorable conditions.
Social learning promotes institutions for governing the commons
TLDR
Neither other-regarding tendencies or preferences for reciprocity and equity, nor group selection or prescriptions from higher authorities, are necessary for the emergence and stability of rudimentary forms of sanctioning institutions regulating common pool resources and enforcing collaborative efforts.
Antisocial pool rewarding does not deter public cooperation
TLDR
It is shown that the ability of defectors to distribute rewards to their like does not deter public cooperation as long as cooperators are able to do the same, and even in the presence of antisocial rewarding, the spatial selection for cooperation in evolutionary social dilemmas is enhanced.
Voluntary rewards mediate the evolution of pool punishment for maintaining public goods in large populations
TLDR
It is demonstrated that a matching fund for rewarding cooperation leads to the emergence of pool punishment, despite the presence of second-order free riders, and suggests that considering the interdependence of reward and punishment may help to better understand the origins and transitions of social norms and institutions.
An economic experiment reveals that humans prefer pool punishment to maintain the commons
TLDR
It is shown that the majority of subjects choose pool punishment, despite being costly even in the absence of defectors, when second-order free-riders, cooperators that do not punish, are also punished.
Competition and cooperation among different punishing strategies in the spatial public goods game
TLDR
It is shown that in the presence of different punishing cooperators the highest level of public cooperation is always attainable through a selection mechanism and that natural strategy selection cannot only promote, but sometimes also hinders competition among prosocial strategies.
Punishment, counterpunishment and sanction enforcement in a social dilemma experiment
We present the results of an experiment that explores the sanctioning behavior of individuals who experience a social dilemma. In the game we study, players choose contribution levels to a public
