Summary: The study found that strategies with a lower probability of volunteering have an advantage in finite populations, but populations of volunteering types also exist in the long run. Monomorphisms with more volunteering types are more common when populations are smaller and the benefits from volunteering are larger.

Summary: The bystander effect refers to the phenomenon where people are less likely to help others in a group than when alone, which can be explained by the volunteer's dilemma. Experimental findings support the prediction that bystanders are more reluctant to help in larger groups. However, individuals in need of help are actually assisted earlier and more often in larger groups, suggesting the influence of diverse social preferences.

Summary: This study investigates the evolution of cooperation in the Volunteer's Dilemma using the stochastic Moran process. The results show that an equilibrium of full cooperation is certain in pairwise interactions given sufficiently high selection pressure, but an impossibility in group interactions.

Summary: Research has found that in a volunteer's dilemma, individuals who volunteer are perceived as more moral and competent. This perception is especially pronounced when all other group members shirk responsibility and when the evaluator is also willing to volunteer.

Summary: The study investigates the evolution of cooperation in the Volunteer's Dilemma using the stochastic Moran process on dynamic graphs, which models a birth-death dynamic on structured finite populations. The results suggest that a high degree of homophily is required for the evolution of cooperation in the Volunteer's Dilemma, while other parameters have relatively small effects on the fixation of cooperation in the population.

Summary: This study examines how repeated interaction facilitates coordinated turn-taking in a two-player Volunteer's Dilemma. The researchers find that turn-taking is dominant when costs are symmetric, but when costs are asymmetric, the low-cost player is more likely to volunteer. However, contrary to predictions, randomly allocated asymmetric costs do not perfectly coordinate turn-taking, and when costs are constant over time, player behavior becomes markedly heterogeneous.

Summary: The study shows that in the volunteer's dilemma, social value orientation does not affect the emergence of solitary volunteering, but does impact the occurrence of turn-taking actions. Additionally, having one strong actor with payoff asymmetry is a necessary condition for solitary volunteering to emerge.

Summary: The study examines various vaccine effectiveness models and vaccine contact-reduction models under different assessments, as well as explores the concept of dilemma strength (DS) and social efficiency deficit (SED) in the context of social dilemma. The findings have implications for policymakers to address social deficiencies in complex situations.

Summary: The prisoner's dilemma game involves two players who can choose to cooperate or defect, with defection being a stable state but cooperation leading to higher payoffs. An optimal control theory is developed to maximize cooperation over a given cycle time by dynamically altering incentives and penalties. This method, based on Pontryagin's maximum principle, is adaptive and has applications in various fields.

Summary: The behavior decisions in social dilemmas are influenced by social distance and rewards and punishment. The results of two studies showed that cooperative behavior is affected by social distance and symmetry of rewards or punishment. Asymmetric punishment had a greater impact on cooperative behavior compared to asymmetric rewards. There was a marginal interaction effect between social distance and symmetry of punishment, with symmetry of punishment being a significant mediator in the relationship between social distance and individual cooperation.

Summary: The paper discusses the application of evolutionary game theory in solving social dilemmas, with a focus on warfare and conflicts. By analyzing historical examples of warfare, the paper proposes a new perspective on how asymmetric players choose strategies and adapt them when additional asymmetric players are involved.

Summary: This study investigates the role of cognitive mechanisms in the emergence of conventions using reinforcement learning models in the repeated volunteer's dilemma. The results show that reinforcement learning models can explain how individuals tacitly agree on a course of action and that contextual cues and equal cost distribution facilitate coordination when optimal solutions are less salient.

Summary: The volunteer's dilemma (VoD) is a group situation where equality-related dispositional and situational factors affect volunteering behavior. Individuals sensitive to suffering from inequality are less likely to volunteer, while those sensitive to benefiting from inequality are more likely to volunteer. Additionally, the previous volunteering rate also influences volunteering behavior.
