In-Person Schooling and Youth Suicide
研究美国线下教学对青少年自杀率的影响，发现疫情学校关闭期间自杀率下降25%，而恢复线下教学后上升12-18%，欺凌可能是机制。
<h3>Abstract</h3> This study explores the effect of in-person schooling on youth suicide in the United States. We show that youth suicide rates historically declined during summers and rose again earlier in counties with an August school starting date. We document a departure from this pattern at the onset of the COVID19 pandemic: youth suicides fell 25 percent in March 2020, when schools closed, and remained low throughout summer. Leveraging county variation in the timing of reopening, we find that returning to in-person instruction increased youth suicides by 12-18 percent. Analysis of Google search data suggests that bullying is a likely mechanism.
