标题： Local Eviction Moratoria and the Spread of COVID-19

摘要： 在新冠疫情初期的不同阶段，美国各州和地方市政当局实施了驱逐暂停令。这些暂停令的主要目的是减缓新冠病毒感染的传播。我们采用了一种半参数双重差分方法，并结合事件研究设计，以检验这些地方暂停令的解除是否导致了新冠病例和死亡人数的增加。在各种规范下，我们的主要发现对于暂停令的影响是不明确的——尤其是在考虑实际驱逐数量并在县一级进行分析后。我们认为最近开发的增强合成控制（ASCM）方法在此情境下更为合适。我们的ASCM结果也表明，解除驱逐暂停令对新冠病例和死亡人数几乎没有影响。因此，似乎驱逐暂停令对减少新冠病毒传播的影响很小或没有，这引发了对其作为非药物干预措施使用的质疑。 显示英文摘要

摘要： At various stages during the initial onset of the COVID-19 pandemic, various US states and local municipalities enacted eviction moratoria. One of the main aims of these moratoria was to slow the spread of COVID-19 infections. We deploy a semiparametric difference-in-differences approach with an event study specification to test whether the lifting of these local moratoria led to an increase in COVID-19 cases and deaths. Our main findings, across a range of specifications, are inconclusive regarding the impact of the moratoria - especially after accounting for the number of actual evictions and conducting the analysis at the county level. We argue that recently developed augmented synthetic control (ASCM) methods are more appropriate in this setting. Our ASCM results also suggest that the lifting of eviction moratoria had little to no impact on COVID-19 cases and deaths. Thus, it seems that eviction moratoria had little to no robust effect on reducing the spread of COVID-19 throwing into question its use as a non-pharmaceutical intervention.
