减少行政负担能否提高社会福利的领取率?本元分析梳理了51项田野实验研究,共报告187个处理效应量。借助行政负担框架对各干预进行比较,我依据各干预所测量的阶段(申请 vs. 最终领取),以及其是通过提供信息降低学习要求、还是通过提供协助降低合规要求,对每项干预重新分类。结果表明,提高申请率比提高实际领取率显著更容易。平均而言,在申请阶段测量结果时估计的处理效应,约为在最终福利领取环节测量时的两倍。最有效的干预是那些降低合规要求的干预,据估计,这些干预平均使实际领取率提高8.31个百分点。降低学习要求的干预据估计平均使实际领取率提高3.39个百分点。这些发现整合了有关如何提高领取率的田野实验证据,并凸显了就申请阶段、处理遵从性以及不同福利体制之间的差异开展进一步研究的必要性。
Abstract
ABSTRACT Can reducing administrative burdens increase the take‐up of social benefits? This meta‐analysis reviews 51 field experimental studies reporting 187 treatment effect sizes. Using the administrative burden framework to compare interventions, I reclassify each intervention by the stage it measures on (application vs. final receipt) and whether it reduces the learning demands by providing information or the compliance demands by providing assistance. The results indicate that it is significantly easier to increase application rates than actual take‐up rates. On average, estimated treatment effects are about twice as large when outcomes are measured at the application stage as when they are measured on final benefit receipt. The most effective interventions are the ones reducing compliance demands, as these are estimated to increase actual take‐up by 8.31 percentage points on average. Interventions reducing learning demands are estimated to increase actual take‐up by 3.39 percentage points on average. These findings consolidate the field experimental evidence on how to improve take‐up rates and highlight the need for further research on application stages, treatment compliance, and variation across welfare regimes.
