我们进行了实验比较的两个著名的机制进行二元公共项目：枢轴机制和自愿捐款机制。我们在完全信息下比较了这两种机制，其中每个主体都知道其他主体的收益。从帕累托效率、个人理性和剩余最大化的角度来看，自愿出资机制比枢纽机制更有效。另一方面，在决策效率方面，两种机制之间没有显著差异。这些结果表明，在实际应用中，自愿出资机制比枢纽机制更有利。
We conduct an experimental comparison of two well-known mechanisms for undertaking a binary public project: the pivotal mechanism and the voluntary contribution mechanism. We compare the two mechanisms under complete information in which each subject knows the other subjects’ payoffs. We then observe that the voluntary contribution mechanism works better than the pivotal mechanism from the perspectives of Pareto efficiency, individual rationality, and surplus maximization. On the other hand, there is no significant difference between the two mechanisms in terms of decision efficiency. These results suggest that the voluntary contribution mechanism is more favorable than the pivotal mechanism in practical applications.
