Summary: This meta-analysis finds that leading-by-example increases contributions in public goods experiments, but leaders benefit less than followers. The imperfect matching of followers' contributions to the leader's results in only a small proportion of group members willing to bear the burden of leadership.

Summary: In the evolution of cooperation, the randomness of individuals' payoffs in real situations introduces unpredictable factors. This study investigates the effects of payoff distribution and network structure on cooperation using simulations. The results show that for normally distributed payoffs, a higher standard deviation inhibits cooperation in one scenario but promotes it in another. For exponentially distributed payoffs, the small-world network provides the best conditions for cooperation emergence.

Summary: Punishing those who refuse to participate in common efforts is a known way to maintain cooperation, but it can make punishers vulnerable and jeopardize effectiveness. Hiring special players to monitor and punish defectors as an alternative using a tax-based fund is suggested. The level of tax and punishment fines are crucial factors in determining coexistence with cooperators or defectors and achieving optimal outcomes.

Summary: The study investigates the impact of environmental unpredictability on pro-environmental behavior, finding that both individual and group pro-environmental behavior decrease when the environment becomes uncertain and unpredictable. This highlights the potential barrier climate change may pose to sustainable behaviors and underscores the importance of environmental prediction.

Summary: Poverty is directly related to numerous social problems, and eliminating it is considered a significant challenge. Allowing low-income individuals to escape poverty through mobility or social learning can greatly increase cooperation and social capital.

Summary: This paper explores a public goods game with two cooperative strategies, proposing models to describe classless and class society scenarios. The results indicate that reducing the cost of quasi-defection can promote quasi-cooperation, and the closer the two inputs are, the better the system performs and the greater the economic benefits. The indispensability of quasi-defection in an interdependence mechanism sometimes leads to more quasi-cooperative agents, and a class system is more advantageous in certain scenarios.

Summary: This study constructs a tripartite repeated game model to analyze the evolution mechanism of suppliers, consumers, and government in the public goods market. It finds stable equilibrium points and verifies the impact of penalty coefficients and discount factors on strategy stability through numerical simulation. The research results provide a reference for decision-making by government, suppliers, and consumers in the public goods supply chain.

Summary: In a public goods game, reinvesting the results of common effort and adding it to the pool for the next round can change players' strategies, especially in structured populations where the last round is crucial for achieving full cooperation. In such cases, it may be advantageous for defectors to support the first round and enjoy the extra benefit of accumulated contributions.

Summary: When people collaborate, they expect more than a simple sum of their efforts. In the public goods game, participants' contributions are multiplied by an r synergy factor before being distributed. This study explores the consequences of different group sizes and synergy factors. Results show that larger groups with higher synergy factors result in higher levels of cooperation, benefiting the entire community. Similar behavior is observed in other heterogeneous topologies.

Summary: This study investigates the evolution of cooperative behaviors in the spatial public goods game. The findings indicate that interaction diversity greatly enhances the level of cooperation compared to the traditional model with homogeneous social scope. The mechanism behind this improvement is based on the inhomogeneous interactive domain, where cooperators can easily maintain their strategies and stabilize the cooperative neighborhood, leading to the emergence of close cooperation clusters. Furthermore, increasing uncertainty in the strategy adoption process can help the system achieve full cooperation when the diversity mechanism is considered.

Summary: Research shows that allowing unconditional transfers enhances public good provision and cooperation in situations involving heterogeneous actors, particularly when resources are transferred from players with high endowment but low productivity to players with high productivity but low endowment, achieving the highest maximum group payoff.

Summary: This study compares public goods game (PGG) and reversed public goods game (R-PGG) and finds that they are equivalent in some cases but behave differently in others. Heterogeneous parameters impede cooperation in R-PGG but promote it in PGG.

Summary: This study uses particle swarm optimization (PSO) to investigate the role of cooperation and punishment in public goods game, finding that intermediate values of the weighting coefficient omega increase the input of punishment, leading to a decrease in cooperation. For low or high values of omega, only cooperators on the edge of clusters tend to punish defectors, thereby increasing the cooperation level of the population.

Summary: This study analyzes the replicator dynamics of tax-based punishment in the public goods game and finds that the combination of taxation and punishment can stabilize cooperation. Interestingly, tax-based punishment and tax-based pure reward can stabilize the same level of cooperation with the same conditions despite their opposite mechanisms.
