Abstract
Assessment studies of occupational exposures are retrospectively evaluated based on their achieved statistical efficiency and/or their imposed costs. However, any decision on the performance of such studies strongly requires an economic evaluation in advance. The economic evaluation of proposed work environmental studies needs, in turn, access to information on the socio-economic impacts of occupational exposures. The present article aims to help policy makers in their decisions on proposed work environmental studies by introducing a cost-value approach to the information to be produced during the studies. The cost-value approach is not exposed to subjective judgements, as in the approach of “willingness to pay”, nor to consideration of invaluable statistical efficiency as “output”, as in exposure assessment studies. The work environmental study investigated in this article contained three different groups of occupational exposures that caused sickness absences and impairments at work in a Swedish company, Sandvik Materials Technology. The results show that the suggested study would be acceptable to the policy makers in the company, as its estimated value was strictly greater than its estimated costs.
