Two different technologies, A and B, have been considered in the manufacturing process. The costs of the factory and annual earnings are given below for both technologies. Capital Costs Earnings (in $millions) (in $millions) End of the Year A B A B 0 $10 $15 $0 $0 1 10 10 -1 0 2 10 0 1 2 3 0 0 5 10 4 0 0 10 10 5 0 0 20 10At the end of five years, technology A will have a scrap value of one million dollars, and technology B will have a scrap value of 5 million dollars. Assume that these two projects are equally risky and the appropriate discount rate is 10 percent per year. Calculate the net present value of each of these factories. Determine if either or both would be feasible. Does it matter whether or not real or nominal terms are used for capital costs, cash flows, and discount rate? Explain.

Scenario 14.4:
John's firm is a competitor in your product market and a monopsonist in the labor market. The current market price of the product that your firm produces is $2. The total product and marginal product of labor are given as:
TP = 100L - 0.125L2 MP = 100 - 0.25L
where L is the amount of labor employed. The supply curve for labor and the marginal expenditure curve for labor are given as follows:
L = PL -5 MEL = 2L + 5

A) Marginal product of labor
B) Marginal revenue product of labor
C) The supply of labor
D) All of the above will shift due to the tax on output.
Q:
In a competitive labor market, the supply of labor curve is expressed as:AE = $5 + 0.0025L,where AE represents the average expenditure ($/unit) and L represents units of labor hired per unit of time.
