10. Suppose an environmental policy proposal is estimated to yield benefits of $100 in year 2 and costs $100 in year 1 and $50 in year 2. Assuming a nominal discount rate of 10 percent, evaluate the fea- sibility of the proposal using the relevant decision criteria. Interpret your findings. Ans: PV(Benefits) = $82.64 PV(Costs) = $132.23 Benefits/Costs ratio < 1 PV(Net Benefits) < 0 Hence, policy is not feasible. 5
