In this study, we examine institutional preferences, social preferences, and contribution in public goods games by conducting a lab-in-the-field experiment in rural China. Specifically, we examine whether people contribute differently depending on whether they are facing their preferred enforcement institution – punishment versus reward – and what factors are behind their institutional preferences.

Abstract: Common identity and peer punishment have been identified as crucial means to reduce free riding and promote cooperation in teams. This paper examines the relative importance of these two mechanisms under two income distributions in team cooperation. In a repeated public good experiment, we use different combinations of homogeneous/heterogeneous endowments, strong/weak identity, and absence/presence of peer punishment.
