Turbomachinery parts inc. is considering two mutually exclusive equipment investments that would increase its production capacity. the firm uses a 14 percent required rate of return to evaluate capital expenditure projects. the two investments have the following costs and expected cash flow streams: year investment d investment e 0 -$50,000 -$50,000 1 24,000 15,000 2 24,000 15,000 3 24,000 15,0004 0 15,0005 0 15,0006 0 15,000a. calculate the net present value for investments d and e. b. create a replacement chain for investment d. assume that the cost of replacing d remains at $50,000 and that the replacement project will generate cash inflows of $24,000 for years 4 through 6. using these figures, recompute the net present value for investment d. c. which of the two investments should be chosen, d or e? why? d. use the equivalent annual annuity method to solve this problem. how does your answer compare with the one obtained in part b?

Consider the local telephone company, a natural monopoly. the following graph shows the monthly demand curve for phone services and the company’s marginal revenue (mr), marginal cost (mc), and average total cost (atc) curves. 0 2 4 6 8 10 12 14 16 18 20 100 90 80 70 60 50 40 30 20 10 0 price (dollars per subscription) quantity (thousands of subscriptions) d mr mc atc 8, 60 suppose that the government has decided not to regulate this industry, and the firm is free to maximize profits, without constraints. complete the first row of the following table. pricing mechanism short run long-run decision quantity price profit (subscriptions) (dollars per subscription) profit maximization marginal-cost pricing average-cost pricing suppose that the government forces the monopolist to set the price equal to marginal cost. complete the second row of the previous table. suppose that the government forces the monopolist to set the price equal to average total cost. complete the third row of the previous table. under average-cost pricing, the government will raise the price of output whenever a firm’s costs increase, and lower the price whenever a firm’s costs decrease. over time, under the average-cost pricing policy, what will the local telephone company most likely do
