a. Suppose that hedonic wage studies indicate a willingness to pay $50 per person for a reduction in the risk of a premature death from an environmental hazard of 1/100,000. If the exposed population is four million people, what is the implied value of a statistical life?

b. Suppose that an impending environmental regulation to control that hazard is expected to reduce the risk of premature death from 6/100,000 to 2/100,000 per year in that exposed population of four million people. Your boss asks you to tell her what is the maximum this regulation could cost and still have the benefits be at least as large as the costs. What is your answer?
