The spatial dimension of internal labor markets
研究了工人跨企业、跨机构和跨地区的流动，发现迁移的工资溢价约为3个百分点，且换工作者的迁移收益源于目的地更好的工作机会。
Abstract We integrate into a unified framework the spatial and the employment dimensions of worker mobility, tracing workers across firms, across establishments, and across regions. Drawing upon the spatial dimension of internal labor markets in firms with multiple establishments in multiple locations, our results indicate that the contemporaneous wage premium to migration is around 3 percentage points. For the case of job switchers, we find that the return to regional migration is due to access to better jobs at the destination. We also document the existence of an urban premium for same‐employer migrants but for employer changes this premium is driven by selection.
