Table H.1.2. Study #2: Dufour, C., Lanoie, P., and Patry, M. Regulation and Productivity, Journal of Productivity Analysis. 1998; 9(3): 233-247.

Research Question:

What was the impact of occupational health and safety (OHS) and environmental regulations on the rate of productivity growth (total factor productivity) in the Quebec manufacturing sector during 1985-1988?

Experimental Design: POOLED TIME SERIES

Pooled time-series using three annual changes between 1985 and 1988, for each of the 19 manufacturing sectors.

Sample Characteristics:

The sample consisted of all Quebec workplaces in 19 manufacturing sectors that were subject to LSST legislation and CSST enforcement during the period 1985-88. The unit of analysis was the sector.

Maintenance of Sample: Not reported.


In Quebec, the 1979 Loi sur la santé et la sécurité du travail (LSST) legislation led to the creation of the Commission de la Sante et Securite du Travail (CSST). The study focused on specific aspects of the Quebec regulation: workplace inspections, investigation of refusal to work, penalties imposed, protective reassignment, and implementation of prevention OHS programs. Although the CSST policies and activities were wide ranging, four of the five selected aspects are cited in another publication (Lanoie, 1992) as being a major focus of their policies and enforcement activities. The level of implementation of the regulation at the firm level increased following the creation of the CSST in 1980, although a number of the requirements had phase-in periods (e.g., prevention programs were legislated in 1979 but employers in Group I and Group II had until July 3, 1983 and May 4, 1984, respectively for preparation of their programs). Additionally, the level of implementation varied across industry sectors as the requirements for OHS prevention programs and JHSCs pertained to firms employing 20 or more workers in 15 high hazard industries.

Data Collection, Data Transformation, and Measurement Properties:

  • Implementation

  • Intermediate


  • Final OHS

Outcomes 6 Economic Outcomes

Dependent variable: total factor productivity growth (TFP) = difference between real output growth and real input growth. Real output growth was based on the annual value of shipments. Real input growth was determined from the following: cost of materials and supplies, cost of fuel and electricity, wages of production and related workers, wages of administrative, office and other non- manufacturing employees, and capital costs (stock and investment, adjusted for depreciation, taxation, etc.).
