Consider an economy with three sectors: fuels and power, manufacturing, and services. fuels and power sells 80% of its output to manufacturing, 10% to services, and retains the rest. manufacturing sells 10% of its output to fuels and power, 80% to services, and retains the rest. services sells 20% to fuels and power, 40% to manufacturing, and retains the rest. a. construct the exchange table for this economy. b. develop a system of equations that leads to prices at which each sector’s income matches its expenses. then write the augmented matrix that can be row reduced to find these prices. c. [m] find a set of equilibrium prices when the price for the services output is 100 units.

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

An investor purchases 500 shares of nevada industries common stock for $22.00 per share today. at t = 1 year, this investor receives a $0.42 per share dividend (which is not reinvested) on the 500 shares and purchases an additional 500 shares for $24.75 per share. at t = 2 years, he receives another $0.42 (not reinvested) per share dividend on 1,000 shares and purchases 600 more shares for $31.25 per share. at t = 3 years, he sells 1,000 of the shares for $35.50 per share and the remaining 600 shares at $36.00 per share, but receives no dividends. assuming no commissions or taxes, the money-weighted rate of return received on this investment is closest to:
