迁移、隔离与跨种族婚姻
Migration, Segregation, and Interracial Marriage
摘要
Abstract Interracial marriage increased substantially in the late 20th century, concurrently with declines in regional and residential segregation. This paper studies whether these trends are related using two historical quasiexperiments and a stylized model of the marriage market. I use a shift-share instrument to find that the Great Migration increased interracial marriage in receiving communities, though this effect was absent in highly segregated cities. Using railroad density as an instrument, I also find that residential segregation decreased interracial marriage. Together, these findings indicate that internal migration and declining segregation contributed to the rise of interracial marriage in the non-Southern United States.

摘要 20世纪末，跨种族婚姻显著增加，与此同时，区域和居住隔离现象有所减少。本文通过两个历史准实验和一个婚姻市场的简化模型，探讨这些趋势是否相互关联。我采用份额转移工具发现，大迁徙增加了接收社区的跨种族婚姻，但在高度隔离的城市中这一效应并不存在。利用铁路密度作为工具变量，我还发现居住隔离降低了跨种族婚姻的发生率。综合这些发现，表明内部迁移和隔离程度的下降促进了美国非南部地区跨种族婚姻的兴起。
