Workers surely aren't fully informed about job risks. Suppose they know that one in ten jobs involves serious exposure to a toxic chemical, but they don't know which jobs carry this risk. Are workers on risky jobs paid more in the competitive equilibrium? Are workers on risky jobs better or worse off than workers on safe jobs? Next, OSHA bans the chemical. What happens to the wage(s)? Are the workers who were on risky jobs better off? Does OSHA's ban help or hurt workers who had been lucky enough to be on safe jobs before the ban
