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

What is the peculiar shape of a natural monopolists average total cost (ATC) curve, and what is the cause of that unusual shape? Fully explain why this type of ATC curve is likely to result in a natural monopoly, and draw a contrast between the ATC curve of a natural monopolist and that of a typical firm in a competitive industry.

14) The demand equation for a monopolist's product is p=200 -0.98q, where p is the price per unit (in dollars) of producing q units. If the total cost c (in dollars) of producing 8 units is given by c= 0.02q2 + 2q + 8000, find the level of production at which profit is maximized.
