中文摘要
同质性社会通常能提供更多公共物品。疫情期间的自愿社交距离也是一种公共物品,但它同样具有私人收益。在理论层面,我们证明,当社会中存在对保持社交距离持不同理由的人口群体时,族群更多样的社会反而可能出现更严格的社交距离遵守行为。在实证层面,我们发现,在当地出现首例COVID-19病例后,族群碎片化程度和排外情绪较高的俄罗斯城市流动性降幅更大。为实现识别,我们利用历史国内人口迁移模式预测首例病例出现的时间。使用美国的流动性数据也得到了类似结果。
Abstract
Homogeneous societies usually provide more public goods. Voluntary social distancing in a pandemic is also a public good, but it has private benefits, too. Theoretically, we show that presence of population groups with different rationales for social distancing can lead to stricter observance of social distancing in more diverse societies. Empirically, we find that mobility reduction following the first local COVID-19 case was stronger in Russian cities with higher ethnic fractionalization and xenophobia. For identification, we predict the timing of the first case using historical patterns of internal migration. Using the United States data on mobility produces similar results.
