摘要本研究考察了在重复公共物品博弈中，群体代表对群体成员请求做出贡献行为的影响。数据来自于参加实验的15个组的135名学生，他们被分成以下处理：无组代表(NR，NRG)和组代表(R1，R2)。我们还测试了群体成员的初始请求(即NRG，R2)在个人水平贡献偏好与群体贡献之间的正向关系。我们使用固定效应GLS回归和IV回归来分析群体代表和群体成员请求的影响。结果表明：(A)轮值小组代表/小组成员的请求与会议(成员内)和小组(小组间)层面的小组贡献有关；(B)对成员请求的反应正向预测了小组贡献；(C)无小组代表处理的受试者通过更多地依赖先前的小组贡献形成其请求，而小组代表处理的受试者更依赖先前的小组成员的请求；以及(D)最初的请求解释了长期贡献水平，这导致在NRG和R2处理之间观察到的小组贡献的差异。我们的发现突出了轮值小组代表在促进成员之间合作方面的作用，而小组成员的请求促使个人在小组层面做出贡献决定。
ABSTRACT This study investigated the effect of group representatives on contribution behaviour in response to group members’ requests in repeated public goods games. Data came from 135 students in 15 groups enrolled in the experiment, grouped in the following treatments: no group representatives (NR, NRG) and group representatives (R1, R2). We also tested initial requests wherein the group members’ initial requests (i.e. NRG, R2) mediated the positive relationship between individual-level contribution preferences and group contributions. We used a fixed-effects GLS regression and IV regression to analyse the effect of group representatives and group members’ requests. The results indicated the following: (a) rotating group representative/group members’ requests was related to group contributions at the session (within-members) and group (between-group) levels; (b) the reactions to members’ requests positively predicted group contributions; (c) subjects in the no group representatives treatment formed their requests by relying more on previous group contributions than subjects in the group representatives treatment, who relied more on the previous group members’ requests; and (d) the initial requests explained long-term contribution levels, which resulted in variations in group contributions observed between the NRG and R2 treatments. Our findings highlight the role of rotating group representatives in stimulating cooperation among members, while group members’ requests impel individuals to make contribution decisions at the group level.
