中文摘要
摘要：我们检验了提高供水与环卫公用事业收入征收效率的两种方式：（i）公用事业工作人员与客户之间的面对面接触；（ii）针对因欠费而断供服务的合同执行，具体表现为透明且可信的断供通知。结果显示，接触没有效果，而执行显著提高了缴费。干预实施九个月后，我们发现对用水可及性、对公用事业的看法、租户与业主之间的关系，以及租户心理健康均没有影响。这些结果表明，透明的合同执行有效提升了收入征收效率，且未产生显著的可观察的社会或政治成本。
Abstract
Abstract We test two ways to improve revenue collection efficiency for water and sanitation utilities: (i) face-to-face engagement between utility staff and customers and (ii) contract enforcement for service disconnection due to nonpayment in the form of transparent and credible disconnection notices. Engagement has no effect, while enforcement significantly increases payment. We find no effect on access to water, perceptions of the utility, relationships between tenants and property owners, or on tenant mental well-being nine months after the intervention. These results suggest that transparent contract enforcement was effective at improving revenue collection efficiency without incurring significant observed social or political costs.
