How Do Mass Shootings Affect Community Well-Being?
利用2008-2016年美国县级数据，研究发现大规模枪击事件会降低社区和情感福祉，且影响持续至少三个月，揭示了事件对非直接受害者的溢出效应。
<h3>Abstract</h3> Over the past four decades, mass shootings have caused at least 1,000 deaths and 1,500 injuries in the US, but little is known about how these tragedies influence people beyond those directly affected. This study uses nationally representative data from the Gallup-Healthways survey to assess spillover effects of mass shootings on individuals' community and emotional wellbeing. Leveraging differences in the timing of mass shootings across counties between 2008-2016, we find that these incidents reduce community and emotional wellbeing for at least three months post-shooting. Mass shootings have high societal costs and create adverse effects that extend beyond those immediately exposed.
