When Work Moves: Job Suburbanization and Black Employment
研究了1970至2000年间就业郊区化是否导致黑人就业率下降，发现黑人更少从事远离市中心的类似工作，且就业郊区化与黑人相对白人就业率下降显著相关。
Abstract This paper examines whether job suburbanization caused declines in black employment rates from 1970 to 2000. I find that black workers are less likely than white workers to work in observably similar jobs that are located further from the central city. Using evidence from establishment relocations, I find that this relationship reflects at least in part the causal effect of job location. At the local labor market level, I find that job suburbanization is associated with substantial declines in black employment rates relative to white employment rates. Evidence from nationally planned highway infrastructure corroborates a causal interpretation.
