BYOB is a monopolist in beer production and distribution in the imaginary economy of Hopsville. Suppose that BYOB cannot price discriminate; that is, it sells its beer at the same price per can to all customers. The following graph shows the marginal cost (MC), marginal revenue (MR), average total cost (ATC), and demand (D) for beer in this market. Place the black point (plus symbol) on the graph to indicate the profit-maximizing price and quantity for BYOB. If BYOB is making a profit, use the green rectangle (triangle symbols) to shade in the area representing its profit. On the other hand, if BYOB is suffering a loss, use the purple rectangle (diamond symbols) to shade in the area representing its loss. 4.00 Esc 3.50 + PRICE (Dollars per can) 3.00 + 2.50 78°F Sunny 2.00 1.50 1.00 + MC 0.50 + F1 1 F2 Ö- @ ATC F3 0+ # F4 F5 ▬ Monopoly Outcome 0 Profit COL F6 Loss O F7 1 F8 n F9 F10 F11 F12 2 Fn Lock ( 1 6/2 Insert Prt Sc

8. Natural monopoly analysis The following graph shows the demand (D) for electricity services in the imaginary town of Utilityburg. The graph also shows the marginal revenue (MR) curve, the marginal cost (MC) curve, and the average total cost (ATC) curve for the local electricity company, a natural monopolist. On the following graph, use the black point (plus symbol) to indicate the profit-maximizing price and quantity for this natural monopolist. 40 36 Monopoly Outcome 32 20 16 АТС -МС 12 8 MR D 0 0 1 2 3 4 5 6 7 8 9 10 QUANTITY (Thousands of kilowatt-hours) 28 24 PRICE (Cents per Kilowatt-hour)
