The effect of recommended contributions in the voluntary provision of public goods
实验研究了推荐捐款对自愿提供公共产品的影响，发现当人们对公共产品估值不同时，推荐能显著提高有效供给的概率，而估值相同时效果不明显。
Recommended contributions are often observed in fundraising campaigns for charitable and other public goods. We present an experiment investigating the impact of recommended contributions in a voluntary threshold public goods process. We find that when valuations for the public good are heterogeneous, recommended contributions significantly increase the likelihood of efficient provision, although when valuations are homogeneous, the effect of recommendations is less compelling. This article represents a first step in understanding recommended contributions and other nonbinding, cheap‐talk announcements in public goods provision and charitable contributions.
