Population Transfers and the Post-Bellum Adjustment to Economic Dislocation, 1870–1920
研究美国内战后1870-1920年间跨区域人口迁移如何消除劳动力市场失衡，估计该迁移使1920年人均收入提高6%。
It is argued in this article that the labor market disequilibrium produced by the American Civil War was substantially eliminated through the process of interregional migration of population over the interval 1870–1920. This migration caused the system of regional labor markets to converge toward a “steady-state” equilibrium. It is estimated that the efficiencies introduced by this migration process explain 6 percent of per capita income levels in 1920.
