Abstract The theoretical and experimental research on opting out (also called conditional dissociation) in social dilemmas has concentrated on the effect this behavior has on the level of cooperation when used against defectors. The intuition behind this emphasis is based on the common property of social dilemmas that individuals are worse off the more their opponents defect. However, this article shows clearly that other opting out mechanisms are better at increasing cooperative behavior. In fact, by analyzing the stable Nash equilibria for the repeated multi-player public goods game with opting out, our results provide a strong argument that the best opting out rule is one whereby the only groups that voluntarily stay together between rounds are those that are homogeneous (i.e., those groups that are either all cooperators or all defectors), when these groups stay together for enough rounds. This outcome emerges when defectors are completely intolerant of individuals who cooperate (e.g., defectors exhibit xenophobic behavior toward cooperators) and so opt out whenever their group has a cooperator in it. The strong preference by defectors to be with like-minded individuals causes all heterogeneous groups to disband after one round.

Altruistic punishment has been shown to invade when rare if individuals are allowed to opt out of cooperative ventures. Individuals that opt out do not contribute to the common enterprise or derive benefits from it. This result is potentially significant because it offers an explanation for the origin of large-scale cooperation in one-shot interactions among unrelated individuals. Here, we show that this result is not a general consequence of optional participation in cooperative activities, but depends on special assumptions about cooperative pay-offs. We extend the pay-off structure of optional participation models to consider the effects of economies and diseconomies of scale in public-goods production, rival and non-rival consumption of goods, and different orderings of the pay-offs of freeriding and opting out. This more general model highlights the kinds of pay-offs for which optional participation favours cooperation, and those in which it does not.

Public Goods Experiment

Abstract With a linear public goods game played in six different variants, this article studies two channels that might moderate social dilemmas and increase cooperation without using pecuniary incentives: moral framing and shaming. We find that cooperation is increased when noncontributing to a public good is framed as morally debatable and socially harmful tax avoidance, while the mere description of a tax context has no effect. However, without social sanctions in place, cooperation quickly deteriorates due to social contagion. We find ‘shaming’ free-riders by disclosing their misdemeanor to act as a strong social sanction, irrespective of the context in which it is applied. Moralizing tax avoidance significantly reinforces shaming, compared with a simple tax context.

Previous research on cooperation has primarily focused on egalitarian interactions, overlooking a fundamental feature of social life: hierarchy and power asymmetry. While recent accounts posit that hierarchies can reduce within-group conflict, individuals who possess high rank or power tend to show less cooperation. Then how is cooperation achieved within groups that contain power asymmetries? To address this question, the present research examines how relative power affects cooperation and strategies, such as punishment and gossip, to promote cooperation in social dilemmas. In two studies involving online real-time interactions in dyads (N = 246) and four-person groups (N = 371), we manipulate power by varying individuals’ ability to distribute resources in a dictator game, and measure punishment, gossip, and cooperative behaviors in a multi-round public goods game. Findings largely replicate previous research showing that punishment and gossip opportunities increase contributions to public goods in four-person groups. However, we find no support for the hypotheses that power directly affects cooperation or the use of punishment and gossip to promote cooperation. We discuss the implications of these findings for understanding the influence of hierarchy and power on cooperation within dyads and groups.

Cooperative Evolution

We introduce a self-questioning mechanism under spatial public goods game in the framework of Evolutionary Game Theory where players are located on a square lattice and realize it by a intensity parameter a. By stimulation and analysis, we find that compared with the original Fermi updating (a=0), the introduction of the self-questioning (a>0) can be better promote cooperative behavior at the smaller r. Subsequently, we stimulate in self-questioning mechanism (a=1), the cooperator frequency fc as a function of the factor r for different values of noise K. Results show that at the larger and smaller noise K, the system presents a considerably different cooperation phenomenon. Whats more, fc as a function of r has center symmetry nature about point (5.0, 0.5) whatever the noise K is. Further analysis indicates the reasons for the formation of these phenomena. Finally, we report the agents average payoff in the steady state and its reasons for it.

The article presents an analysis of the main methodological principles and schemes of social preferences experimental research, which are determined as a fundamental concept to understanding the behavior of decision-makers in the process of resolving social dilemmas. The models presented in the article include an analysis of the factors that determine social preferences. Among them are the factors of trust, reliability, reciprocity, rejection of inequality, unconditional altruism and competitive advantage. The article provides a description of the strengths and weaknesses of the classic methods for studying social preferences, which usually take the form of ultimatum game, dictator game, trust game and public goods game. The study reveals the importance of the Nash equilibrium as a way to interpret human behavior in resource allocation during the game. Analysis of numerous literary sources shows that the ultimatum game is a classic scheme for studying the altruistic behavior of people. The submission of a proposal and its acceptance is an example of Nash's ideal equilibrium. Deviation from this balance can be interpreted as altruism. In turn, the trust game is a classic scheme for studying the reciprocity and prosocial orientation. If the behavior of players deviates from Nash's equilibrium, it is interpreted as being caused by trust and reciprocity. The dictator game is a classic scheme for studying the rejection of inequality. The subject's behavior can be interpreted as a rejection of inequality or altruism, but not as a rejection of risk, as the offer of Player 1 is mandatory for Player 2. Public goods game is a classic scheme for studying the competitive orientation. Nash's ideal balance in this form of play is to do nothing for public consumption, but deviating from this rule is interpreted as altruistic behavior that is the opposite of competitive orientation. As a result, the design of psychological research is presented, which most accurately typologies the social preferences of the subjects and can contribute to the creation of a representative model of decision-making process.

We experimentally examine private information and communication in a public goods environment with uncertain returns. We consider a common-value public goods game in which the return to contribution is either high or low. Before contributing, three players observe private signals correlated with the return and send cheap talk messages to one another. There are social gains from truthfulness, but a private incentive to exaggerate. We compare treatments with and without cheap talk, finding that communication is largely truthful and increases efficiency. In further treatments, we increase the incentive to exaggerate and find reduced truthfulness and smaller gains from communication. (JEL C72, D82, D83, H41)

Who is cooperative? Although Big Five (B5) Agreeableness and HEXACO Honesty-Humility are correlates of charitable prosociality, distinctions between “charity” and “cooperation” suggest that additional traits could be associated with cooperative prosociality. Echoing prior theoretical and empirical indications that B5 Openness/Intellect may play a role in cooperation, Study 1 ( N = 119; exploratory) revealed a significant correlation between Openness/Intellect and cooperativeness in the one-shot Public Goods Game that did not generalize to charitableness in the Dictator Game. We therefore conducted three preregistered replications to discern the robustness of this Openness/Intellect–cooperativeness link. As expected, Openness/Intellect showed no consistent correlation with charitable behavior. Surprisingly, the predicted correlation between Openness/Intellect and cooperative behavior was also inconsistent, partially replicating in Study 3 ( N = 304) but not Studies 2 or 4 ( Ns = 131; 552). Across our replications, cooperative behavior was most strongly correlated with Honesty-Humility (internal meta-analytic [Formula: see text] = .15, p = .005). The correlation between Openness/Intellect and cooperative behavior across our replications was significant and identical in magnitude to that between Agreeableness and cooperative behavior, though this effect-size was weak (internal meta-analytic [Formula: see text] = .08, p < .001). We therefore conclude that Openness/Intellect is a nonnull but very modest correlate of cooperativeness.

Human cooperation is often claimed to be special and requiring explanations based on gene–culture coevolution favouring a desire to copy common social behaviours. If this is true, then individuals should be motivated to both observe and copy common social behaviours. Previous economic experiments, using the public goods game, have suggested individuals' desire to sacrifice for the common good and to copy common social behaviours. However, previous experiments have often not shown examples of success. Here we test, on 489 participants, whether individuals are more motivated to learn about, and more likely to copy, either common or successful behaviours. Using the same social dilemma and standard instructions, we find that individuals were primarily motivated to learn from successful rather than common behaviours. Consequently, social learning disfavoured costly cooperation, even when individuals could observe a stable, pro-social level of cooperation. Our results call into question explanations for human cooperation based on cultural evolution and/or a desire to conform with common social behaviours. Instead, our results indicate that participants were motivated by personal gain, but initially confused, despite receiving standard instructions. When individuals could learn from success, they learned to cooperate less, suggesting that human cooperation is maybe not so special after all.

Cooperative vehicular networking has been widely studied in recent years. Existing evolution game theoretic approaches to study cooperative behavior in Vehicular Ad hoc Network (VANET) are mainly based on the assumption that VANET is constructed as a homogeneous network. This modeling method only extracts part attributes of vehicles and does not distinguish the differences between strategy and attribute. In this paper, we focus on the heterogeneous network model based on the public goods game theory for VANET. Then we propose a Dynamic Altruism Public Goods Game (DAPGG) model consisting of rational nodes, altruistic nodes, and zealots to more realistically characterize the real VANET. Rational nodes only care about their own benefits, altruistic nodes comprehensively consider the payoffs in the neighborhood, while zealots insist on behaving cooperatively. Finally, we explore the impacts of these attributes on the evolution of cooperation under different network conditions. The simulation results show that only adding altruistic nodes can effectively improve the proportion of cooperators, but it may cause conflicts between individual benefits and neighborhood benefits. Altruistic nodes together with zealots can better improve the proportion of cooperators, even if the network conditions are not suitable for the spread of cooperative behavior.
