社会可观察性与转移支付需求:来自低收入人群的实验证据

Social Observability and Demand for Transfers: Experimental Evidence from a Low Income Population
Journal of Public Economics · 2025 · Marcel Fafchamps、Fadela Sadou Zouleya

中文摘要

我们考察社会可观察性如何影响低收入个体申请经济支持的意愿。参与者在实验室中完成任务以赚取收入后,可以申请由一项专门面向最低收入者的社会基金提供的转移支付。我们通过实验改变申请是公开还是私下进行,以及资金来自实验人员还是其他参与者。我们发现,公开申请使领取率降低31个百分点。加入同伴资助会使领取率进一步降低10个百分点。当收入是通过努力而非抽签获得时,以及公开可见性与同伴资助同时存在时,这些效应最强。上述发现并非由利他偏好或再分配偏好所驱动,但换位思考会使参与者对公开申请处理更加敏感。我们的研究结果表明,确保申请过程的私密性有助于提高收入支持项目的可及性。

Abstract

We examine how social observability affects the willingness of low-income individuals to apply for financial support. After completing tasks to earn income in the lab, participants are given the opportunity to apply for a transfer from a social fund earmarked for the lowest earners. We experimentally vary whether the application is public or private and whether the funds come from the experimenters or other participants. We find that making the application public reduces take-up by 31 percentage points. Adding peer funding leads to a further 10 percentage point drop. These effects are strongest when income is earned through effort instead of a lottery, and when both public visibility and peer funding are present. The findings are not driven by altruistic or redistributive preferences, but perspective taking makes participants more sensitive to the public application treatment. Our findings suggest that ensuring privacy in the application process helps increase access to income support programs.
