Revisiting the Effects of Group Identity and Information Diversity in a Leader-member Public Goods Experiment


We investigate the willingness to cooperate between leaders and members in a repeated public goods experiment, when there is group identity and information diversity between them. The participants who play the role of leader, first decide their contributions to the team project. Subsequently, members also decide their contributions. The results indicate that having the same group identity as the leader has a positive effect on members' intention to fully cooperate with the leader Additionally, in the case of being in the same group, disclosing information only to members may increase cooperation. Finally, cooperative behavior between members is closely related to the identity of the leader and information diversity.
