Data for: How to subsidize contributions to public goods: Does the frog jump out of the boiling water?

Abstract of associated article: According to popular belief, frogs are boiled to death when the water is heated gradually. In this paper, we investigate how humans respond to a very slow versus a very steep increase of a subsidy on contributions to a public good. In an experiment, we vary the mode of the increase (gradual versus quick). When the subsidy is raised to an intermediate level, we see a modest effect in either treatment. When the subsidy is raised to a substantial level, there is a strong effect of a quick increase and a modest effect of a gradual increase in the subsidy.关联论文摘要：坊间普遍认为，若将水温缓慢加热，青蛙会被煮死。本文针对公共物品（public good）贡献补贴的增幅分别为极缓慢与极陡峭两种情形，探究人类的行为响应。本实验通过调整补贴增幅的模式（缓慢增幅与快速增幅）开展研究。当补贴提升至中等水平时，两种实验处理下均仅观测到适度的影响效果。而当补贴提升至较高水平时，快速增幅处理会产生显著的影响效果，缓慢增幅处理则仅呈现出适度的影响。
