Environmental Regulation and Labor Reallocation: Evidence from the Clean Air Act
利用工厂级监管状态数据与人口普查纵向商业数据库，研究发现1990年《清洁空气法》修正案导致的县级环境规制变化使受监管行业规模在10年内减少高达15%。
This paper uses newly available data on plant level regulatory status linked to the Census Longitudinal Business Database to measure the impact of changes in county level environmental regulations on plant and sector employment levels. Estimates from a variety of specifications suggest a strong connection between changes in environmental regulatory stringency and both employment growth and levels in the affected sectors. The preferred estimates suggest that changes in county level regulatory status due to the 1990 Clean Air Act Amendments reduced the size of the regulated sector by as much as 15 percent in the 10 years following the changes.
