Consistent Output Series for the Antebellum and Postbellum Periods: Issues and Preliminary Results
现有覆盖美国内战前后时期的产出序列不一致，无法比较19世纪的周期模式。更一致的数据显示，内战前周期性敏感部门的产出波动并不小于、甚至可能大于战后。
Existing output series that cover both the antebellum and postbellum periods are inconsistent and unsuitable for comparing cyclical patterns across the nineteenth century. More consistent data show that output in cyclically sensitive sectors was no less, and probably more, volatile before the War Between the States than after it.
