The determinants of OSHA performance can be examined by breaking the regula
tory process into three elements relating to enforcement, compliance behavi
or, and the adequacy of standards in addressing safety outcomes. This paper
develops and applies this framework to the U.S. construction industry duri
ng the period 1987 to 1993. Enforcement activity among the firms in the sam
ple was substantial, with firms facing a high probability, of annual inspec
tion. But, despite this significant enforcement effort, inspections have a
modest effect on firm compliance with OSHA standards. Finally, the health a
nd safety standards cited most frequently diverge from the major sources of
fatalities and injuries on construction projects. These results suggest th
at historic enforcement policies toward construction make less sense as OSH
A moves into its fourth decade of operation. More generally, the paper illu
strates the problem of focusing enforcement resources on large, high-profil
e companies even though they often are not the major source of regulatory p
roblems in an established area of public policy, intervention. (C) 2001 by
