中文摘要
利用北方城市铁路轨道的布局，我们考察种族隔离在多大程度上影响不同种族的凶杀受害情况。结果显示，种族隔离与非白人凶杀受害之间存在稳健的正向关系。此外，我们发现公共供给随之减少：高度隔离的地区财政收入更低，公共支出也更少。研究发现表明，白人迁离与种族隔离侵蚀了地方税基，导致城市衰败与犯罪率上升，最终造成非白人生命的损失。（JEL H71, I32, J15, K42, R23）
Abstract
Exploiting the arrangement of railroad tracks in northern cities, we explore the extent to which segregation impacts homicide victimization by race. Our results reveal a robust positive relationship between segregation and non-White homicide victimization. In addition, we find a decrease in public provisions, as highly segregated locations generate fewer revenues and have lower public expenditures. Our findings suggest that White flight and segregation deplete the local tax base, leading to urban decay and higher crime, resulting in the loss of non-White lives. (JEL H71, I32, J15, K42, R23)
