The Long Run Effects of Labor Migration on Human Capital Formation in Communities of Origin
利用马拉维到南非矿山的循环迁移数据，研究发现迁移机会通过提高下一代受教育程度，对原籍社区人力资本产生长期正面影响。
We provide new evidence of one channel through which circular labor migration has long-run effects on origin communities: by raising completed human capital of the next generation. We estimate the net effects of migration from Malawi to South African mines using newly digitized census and administrative data on access to mine jobs, a difference-in-differences strategy, and two opposite-signed and plausibly exogenous shocks to the option to migrate. Twenty years after these shocks, human capital is 4.8–6.9 percent higher among cohorts who were eligible for schooling in communities with the easiest access to migrant jobs.
