AI 中文摘要
人们在危机期间是否会对自己所在群体表现出更友善的行为？我们以地域划分内群体和外群体，研究新冠疫情期间人们对本地与外地慈善机构的捐赠情况。证据表明狭隘性有所增加：我们发现本地慈善机构的捐赠相对增加，且新冠疫情严重地区的捐赠者增加了本地捐赠，对国际灾难的响应也降低了。本地捐赠的增加在疫情第一年最为明显。我们认为，捐赠中狭隘性的增加是由于疫情期间地方关注度高，人们对新冠疫情的直接影响担忧加剧所致。
英文摘要
Do people behave more favorably towards their in-group during a crisis? Defining in/out-groups by geography, we study donations to local versus non-local charities during the Covid pandemic. The evidence points to increased parochialism: We document a relative increase in donations to local charities and show that donors in high-Covid areas increased their local giving and became less responsive to international disasters. Increased local giving was most pronounced during the first year of the pandemic. Our interpretation is that greater parochialism in donations was due to heightened concern about the immediate impact of Covid at a time when localities were salient.
