This paper conducts laboratory experiments to investigate how the individuals with heterogeneous income levels endogenously select the institution in public good provision in a Tiebout-like environment. According to the experimental results, I find that heterogeneous individuals have different choices of contribution institutions. High-income individuals tend to participate in the voluntary contribution institution, but low-income individuals tend to choose the compulsory one. I also find that most high-income individuals in the voluntary contribution institution try to free ride on others. Therefore, although the vote-with-feet mechanism helps to sort heterogeneous individuals in different contribution institutions, it may not enhance the cooperation among the individuals in the voluntary contribution community.

投票表决机制下自愿提供和强制提供公共物品的实验研究

本文进行了实验室实验，以研究在Tiebout式的环境中，收入水平不同的个人如何在公共物品提供中内生地选择机构。根据实验结果，我发现异类个体对贡献机构的选择不同。高收入个人倾向于参加自愿捐款制度，而低收入个人倾向于选择强制性捐款制度。我还发现，自愿捐款机构中的大多数高收入人士都试图搭便车。因此，尽管“用脚投票”机制有助于对不同贡献机构中的异类个体进行分类，但它可能无法增强自愿性贡献社区中个体之间的合作。
