Reestimating Osha's Effects: Have the Data Changed?
复制了早期关于OSHA检查效果的研究，发现即使记录保存和检查程序有变化，检查（或威胁）仍未能降低工伤率，且新程序导致未受检企业报告偏向下行。
Our analysis replicates earlier studies of OSHA's inspection effects to see if, in the face of recordkeeping changes and new inspection targeting procedures, the relationships previously found still hold. The sizes and patterns of coefficients that we obtain in our analyses, including the lack of evidence that OSHA inspections (or the threat of them) reduce the injury rate, are consistent with those found earlier. We also analyze whether the new inspection procedure resulted in the reduction of reported injury rates among both inspected and uninspected plants. Consistent with an earlier paper, we find some downward bias in reporting among uninspectedfirms affected by the records-check procedure; however, we do not find this reporting bias among inspected plants.
