We conducted a fundraising experiment with an international development nonprofit organization in which a matching grant offered by the Bill and Melinda Gates Foundation raised more funds than one from an anonymous donor. The effect is strongest for solicitees who previously gave to other BMGF-supported, poverty charities. With supporting evidence from two other fundraising experiments as well as a survey experiment, we argue this is consistent with a quality signal mechanism. Alternative mechanisms are discussed, and not ruled out. The results help inform theories about charitable giving decision-making, and provide guidance to organizations and large donors on how to overcome information asymmetries hindering fundraising.
我们与一家国际发展非营利组织进行了一项筹款实验，实验中比尔及梅琳达·盖茨基金会提供的配对赠款比匿名捐赠者提供的赠款筹集到了更多资金。对于之前向其他由比尔及梅琳达·盖茨基金会支持的扶贫慈善机构捐款的受捐者来说，这种效应最为明显。结合另外两项筹款实验以及一项调查实验的支持证据，我们认为这与质量信号机制相符。我们讨论了其他机制，但并未将其排除。研究结果有助于为慈善捐赠决策理论提供参考，并为组织和大型捐赠者提供指导，帮助他们克服阻碍筹款的信息不对称问题。
