We investigate the impact of occupational safety and health (OSH) and
environmental regulation on the rate of growth of total factor product
ivity (TFP) in the Quebec manufacturing sector during the 1985-88 peri
od. Our results show that environmental regulation and OSH protective
reassignments (a prevention policy with respect to OSH) have led to a
reduction in productivity growth, while the presence of mandatory prev
ention programs and of fines for infractions to OSH rules have led to
an increase in productivity growth. Interestingly, this is, to our kno
wledge, the first result showing that OSH regulation may have had a po
sitive effect on productivity growth.
