我们在一个在线筹款平台上进行了一个大规模的实地实验，研究了违约对慈善捐赠的影响。我们从外部改变默认选项的沿着两个选择维度：慈善捐赠决定和“共同捐赠”决定，即为支持平台贡献多少。我们记录了违约对个人行为的强烈影响，但发现总捐赠水平不受违约的影响。相比之下，共同捐赠增加默认金额。我们补充我们的实验结果与结构模型，调查是否个性化的默认值的基础上，个人的捐赠历史可以增加捐赠收入。
We study the effects of defaults on charitable giving in a large-scale field experiment on an online fundraising platform. We exogenously vary default options along two choice dimensions: the charitable donation decision and the "co-donation" decision regarding how much to contribute to supporting the platform. We document a strong effect of defaults on individual behavior but nevertheless find that aggregate donation levels are unaffected by defaults. In contrast, co-donations increase in the default amount. We complement our experimental results with a structural model that investigates whether personalizing defaults based on individuals' donation histories can increase donation revenues.
