a) Find the long run equilibrium price. Find the minimum efficient scale of the typical firm. Find the typical firm’s average cost when it operates at minimum efficient scale. In the long run, what price will prevail in this market? In words, clearly justify your answer. Suppose demand is QD = 3,200 – 100P. (b) Explain why you expect the number of firms in this market to be fifty-five. In this market, what is the short run supply function of the typical firm? What is the short run market supply function? Suppose the local government introduced a $90 licensing fee that raised the fixed cost from $160 to $250. c) Would the introduction of the licensing fee affect the short run equilibrium price or quantity? Justify your answer? Clearly explain why you expect that in the long run fewer larger firms will operate in this market. After the introduction of the licensing fee, what is the new long run equilibrium price? How many firms will survive in this market?
The curves show the marginal revenue (MR), marginal cost (MC), and average total cost (ATC) functions for a firm in a competitive market. Use the area tool to draw the area representing the maximum profit the firm could earn—that is, the profit the firm would earn if it produced the optimal quantity.

Assume that if the firm is indifferent between producing and shutting down, it will produce. (Hint: You can select the purple points [diamond symbols] on the graph to see precise information on average variable cost.)

4. A vertically integrated automobile company has an upstream engine division and a downstream assembly division. The demand for the company's cars is given by Q = 20-P. Each car requires one engine. The downstream division's total cost of assembling cars is TCD(Q) = 4Q. The upstream division's total cost of producing engines is TCv (Q) = Q². (a) Suppose that there is no outside market for engines. What is the price and quantity of cars produced by the company? (b) Suppose that there is no outside market for engines. What should be the transfer price for engines? [Hint: the transfer price of an engine should equal the marginal cost of engine production at the optimal quantity.] (c) Suppose that there is a competitive outside market in which the price of an engine is 12. What is the price and quantity of cars produced by the company? (d) Suppose that there is a competitive outside market in which the price of an engine is 12. What is the quantity of engines that the company buys or…

Using the following table, for each price level, calculate the optimal quantity of units for the firm to produce. Using the data from the graph to determine the firm’s total variable cost, calculate the profit or loss associated with producing that quantity. Assume that if the firm is indifferent between producing and shutting down, it will choose to produce. (Hint: Select purple points [diamond symbols] on the graph to receive exact average variable cost information.)

The following graph plots daily cost curves for a firm operating in the competitive market for fitness trackers.

On the preceding graph, use the blue rectangle (circle symbols) to fill in the area that represents profit or loss of the firm given the market price of $45 and the quantity of production from your previous answer. Note: In the following question, enter a positive number regardless of whether the firm earns a profit or incurs a loss. The rectangular area represents a short-run thousand per day for the firm.
Farmer Brown grows peaches. The average total cost and marginal cost of growing peaches for an individual farmer are illustrated in the graph to the right. Assume the market for peaches is perfectly competitive and that the market price is $40 per box. Also assume that farmer Brown is producing the amount of peaches that maximizes profits. Use the rectangle drawing tool to shade in farmer Brown's profit. Properly label this shaded area. Carefully follow the instructions above, and only draw the required objects.

The average total cost curve for each option is shown in the graph. If the market demand for copies is 12,000 copies per day, how many copy shops would you expect to see in this market? The answer depends on the price of a copy, which is unknown. O 1 (because the copy shop will become a monopoly with a large quantity demanded) O (because the copy shop can't produce 12,000 copies efficiently and will shutdown) 3 (with each shop supplying 4000 copies per day) 8, 6 Average cost (cents per copy)
