In this paper, we find that higher levels of in-migration dilute multiple dimensions of a community’s social capital, with some measures of a community’s social capital being negatively impacted more than others. Using a spatial model and restricted-access microdata from the US Census Bureau, we employ an instrumental variables strategy to account for the endogeneity of migration. Our results suggest that political activism, overall, is most negatively impacted by in-migration, and that religiosity, trust, and community involvement are impacted more negatively in rural communities compared to non-rural communities.

社区社会资本的迁入与稀释

在本文中，我们发现较高水平的移民会稀释社区的社会资本的多个维度，而对社区的社会资本的某些衡量则受到的负面影响要大于其他方面。利用美国人口普查局的空间模型和受限访问的微数据，我们采用了一种工具变量策略来说明移民的内生性。我们的结果表明，总体而言，政治行动主义受到移民的负面影响，与非农村社区相比，农村社区的宗教信仰，信任和社区参与受到的负面影响更大。
