The Impact of Occupational Safety and Health Regulation, 1973-1983
利用1973-1983年美国制造业数据，重新检验职业安全与健康管理局（OSHA）对工作场所安全的影响，发现仅在工伤和疾病发生率上存在统计显著但幅度不大的效果，且该效果不稳健。
Using a sample of manufacturing industries from 1973 to 1983, this article reexamines OSHA's impact on workplace safety. Evidence supporting OSHA's effectiveness is stronger than that presented in most previous studies but remains quite mixed. Only for the incidence of lost workday injuries and illnesses is there evidence of a statistically significant OSHA impact for an equation that is stable over the 1973-1983 period. The magnitude of the effect is modest, and the effect is not robust with respect to different risk variables. For the three risk variables examined, there is no evidence of endogeneity of the contemporaneous OSHA enforcement variable.
