Abstract

Considering the impact of reputation on social benefits of people in reality, we introduce the reputation-based payoff transfer mechanism to investigate cooperative behaviors on the lattice in the process of public goods game (PGG). Here individual reputation is quantified by score rules and players are ranked based on reputation scores. Payoffs can be transferred from low-ranking groups to high-ranking individuals via three different kinds of transfer ratios, and thus players with high rank receive endogenous bonus without the external funds. Numerical simulations show that the level of cooperation in PGG gets slightly increase in the type of conditional transfer ratios. But cooperation can be significantly promoted and maintained at a high level in the type of effective transfer ratios. The effect of transfer strength (s) is also considered. The greater the s, the higher the cooperation level for most transfer ratios. And when the optimal transfer ratio condition is met, cooperation can quickly be emergent and nearly reach global cooperation even if the synergy factor is small. Our research is helpful to shed light on the emergence of cooperation in PGG and provides useful advices for organizers to promote the collective supply of public goods from the perspective of reputation management.

在公益游戏中通过基于声誉的收益转移机制促进合作

摘要

考虑到声誉对现实中人们社会福利的影响，我们引入了基于声誉的收益转移机制，以研究公共物品博弈（PGG）过程中格子上的合作行为。在这里，个人声誉是通过得分规则来量化的，玩家是根据声誉得分来排名的。收益可以通过三种不同的转移比率从低等级的团队转移到高等级的个人，因此，高等级的玩家无需外部资金即可获得内生奖金。数值模拟表明，在有条件转移比率的类型中，PGG中的协作水平略有增加。但是，在有效转移比率的类型上，可以大大促进和维持高水平的合作。传递强度的影响（s）也考虑在内。在更大的小号，对于大多数传输比合作水平越高。并且，当满足最佳转移比率条件时，即使协同因子很小，合作也可以迅速出现并几乎达到全球合作。我们的研究有助于阐明PGG中合作的出现，并为组织者从声誉管理的角度促进公共物品的集体供应提供有益的建议。
