You should compute the net present value of net benefits of the policies you analyzed in Assignment 6, Part II, Question 1. The four policies from Assignment 6 are characterized by constant emission reductions relative to the no-policy (base case) scenario. You should do this using three different discount schemes: a constant discount rate of 2%, 3.5% and 5% per year. Remember that the net benefits in each year of a given policy are defined as the increase in consumption in that year relative to the no-policy scenario. The deliverable for this exercise is a table that lists the net present value of net benefits of each of the four policies for the three discounting schemes listed above. Finally, for each policy and discounting combination you should write down whether the policy would pass a cost-benefit test
