This paper estimates workers' demand function for job safety using the Brit
ish General Household Survey data. The estimation employs Rosen's two-stage
procedure. The main difference between our study and those done in the pas
t is that we estimate hedonic price equations with data sets from two labou
r markets. Our approach overcomes the usual identification problems associa
ted with the application of Rosen's method. The estimation shows that there
is a significant wage compensation for job risk in the UK. The willingness
-to-pay for a 1/100 000 decrease of annual job fatal accident rate from our
estimated workers' demand function is about pound 6 in 1973 prices. The es
timation of a demand function for safety also enables the derivation of wor
kers' willingness-to-pay for non-marginal change of job risk, and this can
be used for cost-benefit analysis on projects involving such non-marginal c
hanges.
