This study investigates the impact of incidental happiness associated with the outcome of the Dutch national soccer championship on charitable giving shortly after the decisive match. We use survey data in which participants were asked to make an anonymous donation of an earned endowment. For estimating the causal effect of happiness on charitable giving, we exploit the variation in the emotions of fans between and within teams using two complementary empirical approaches. The first approach is based on the preference of fans for local teams. We find that individuals living closer to the city of the new champions (Amsterdam) are happier and also more likely to donate to charity than individuals living further away. Importantly, distance to Amsterdam does not affect charitable giving in a placebo sample of individuals with no interest in soccer. The second approach exploits variation between different types of fans within teams. Allegiant fans, individuals who attended a match, are happier and more likely to donate to charity than “stay-at-home” fans when their team wins the title. Allegiant fans are less happy and less likely to donate than stay-at-home fans when their team does not win the title. Instrumental variable estimates suggest a large effect of incidental happiness on charitable giving.

利他行为与足球：偶然的幸福对慈善捐赠的影响

本研究调查了与荷兰国家足球锦标赛结果相关的附带幸福感对决定性比赛后不久的慈善捐赠的影响。我们使用调查数据，其中参与者被要求匿名捐赠赚取的捐赠。为了估计幸福感对慈善捐赠的因果影响，我们使用两种互补的实证方法来利用球队之间和球队内部球迷情绪的变化。第一种方法是基于球迷对当地球队的偏好。我们发现，居住在距离新冠军城市（阿姆斯特丹）较近的个人比居住较远的个人更快乐，也更有可能向慈善机构捐款。重要的是，距阿姆斯特丹的距离并不影响对足球不感兴趣的安慰剂样本的慈善捐赠。第二种方法利用了球队内不同类型球迷之间的差异。当球队赢得冠军时，忠诚的球迷（即现场观看比赛的个人）比“呆在家里”的球迷更高兴，也更有可能向慈善机构捐款。当球队没有赢得冠军时，忠诚的球迷比呆在家里的球迷更不高兴，也更不愿意捐款。工具变量估计表明偶然的幸福感对慈善捐赠有很大影响。
