We experimentally examine if reductions in inequality that do not lower the endowments of the rich raise contributions to public goods in formerly unequal groups. Even injections of additional resources directed to the poor fail to raise cooperation to levels observed in groups that were always equal and have fewer resources. Our results suggest that the poor mimic the unchanging selfish behaviour of the rich, and divert resources to private consumption.

减少不平等与合作：注入额外资源

我们通过实验检验在不降低富人禀赋的情况下减少不平等是否会增加以前不平等群体对公共物品的贡献。即使向穷人注入额外资源，也未能将合作提高到始终平等且资源较少的群体中观察到的水平。我们的研究结果表明，穷人模仿富人一成不变的自私行为，并将资源转移到私人消费。
