The Growth of Wages in Antebellum America: New Evidence
利用美国陆军雇佣平民的工资记录，估算了1820-1856年的名义日工资率，发现技能差异未长期扩大，东北部实际工资增长比以往认为的更慢且更不稳定。
The records of the United States Army, which hired civilian workers in the nineteenth century, have produced a large sample of wage rates. New estimates of nominal daily wage rates from 1820 to 1856 are presented. There is no evidence of a long-term increase in the skill differential. The growth of real wages in the Northeast appears to have been slower and more erratic than previously thought. Regional trends in wages are consistent with other evidence on patterns of regional growth and internal migration.
