An Experimental Analysis of Unanimity in Public Goods Provision Mechanisms
通过实验比较了直接贡献和公共品拍卖两种公共品分配方法，并考察了加入一致同意规则后的效果。结果发现拍卖优于直接贡献，而一致同意规则降低了两种机制的效率。
The paper reports on an experimental investigation of four methods of allocating public goods. The two basic processes studied are direct contribution and a public goods auction process. Both of these processes are studied with and without an additional unanimity feature. The results suggest that the auction process outperforms direct contribution. The effect of unanimity is to decrease the efficiency of both processes. Much of the paper is focused on an analysis of these results.
