Suppose that the objective for three major firms in an urban area is a 50 percent reduction in carbon monoxide (CO) emissions. Each firm is now emitting 10 tons per week or a total of 30 tons per week. The total emissions level needs to be reduced to 15 tons per week. There are two methods that have been used for emission reduction: the uniform or equi-proportional method and the cost-effective or equi-marginal method. The traditionally used method was to mandate that each firm reduce their emissions by the same amount or equi-proportional. New methods that attempt to harness the creativity of market incentives use the equi-marginal method because it promotes cost-effectiveness. Given the marginal abatement costs for three firms for different emissions levels: Emissions [tons per week] 10 9 8 7 6 5 4 3 2 1 0 MAC [$/ton] Firm 1 0 4 8 12 16 20 24 28 36 46 58 Firm 2 0 1 2 4 6 8 12 20 24 28 36 Firm 3 0 1 2 3 4 5 6 7 8 9 10 1. Calculate: Equi-proportional: each firm emissions = 5 tons per week Emissions MAC Total Cost Firm 1 Firm 2 Firm 3 Total 3 firm cost=

A firm is considering whether to lease or buy a machine that costs $100,000. The machine would be kept for three years. The firm's cost of debt is 10% and its tax rate is 40%. If the machine is owned, then the company would have to pay $10,000 per year in maintenance costs (payable at the end of the year). If the machine is leased, then the maintenance will be taken care of by the lessor. If leased, the lease payments would be $35,000 at time zero and at the end of each of the next three years. Assume straight-line depreciation to a salvage value of $0 three years from now. What is the net advantage to leasing, if any?
