Exam 12: Firms in Perfectly Competitive Markets

Some markets have many buyers and sellers but fall into the category of monopolistic competition rather than perfect competition. The most common reason for this is

Producing where marginal revenue equals marginal cost is equivalent to producing where

Figure 12-2 -Refer to Figure 12-2. The firm breaks even at an output level of

The market demand curve in a perfectly competitive market is downward sloping.

Figure 12-9 Figure 12-9 shows cost and demand curves facing a profit-maximizing, perfectly competitive firm. -Refer to Figure 12-9. At price P3, the firm would produce

The price of a seller's product in perfect competition is determined by

Table 12-5 Use the table to answer the following questions. a. Complete Table 12-5 by filling in the blank cells. b. Werner is selling in a perfectly competitive market at a price of $40. What is the profit maximizing or loss-minimizing output? c. Calculate the firm's profit or loss. d. Should the firm continue to produce in the short run? Explain. e. If the firm's fixed costs were $30 higher what would be the profit-maximizing output level in the short run? Indicate whether the output level will increase, decrease or remain unchanged compared to your answer in b. f. Suppose fixed cost remains at $76. If the price of three-ring binders falls to $20 what is the profit-maximizing or loss-minimizing output? g. Calculate the profit or loss. Should the firm continue to produce in the short run? Explain your answer. h. Suppose the fixed cost remains at $76. What price corresponds to the shut-down point? i. Suppose the fixed cost remains at $76. What price corresponds to the break-even point? -Werner & Sons is a manufacturer of three-ring binders operating in a perfectly competitive industry. Table 12-5 shows the firm's cost schedule.

For a perfectly competitive firm, average revenue is equal to

Figure 12-5 Figure 12-5 shows cost and demand curves facing a typical firm in a constant-cost, perfectly competitive industry. -Refer to Figure 12-5. What is the minimum price the firm requires to produce output?

Which of the following is not an option for a perfectly competitive firm that suffers short-run losses?

The marginal revenue curve for a perfectly competitive firm

What is meant by allocative efficiency? How does a perfectly competitive firm achieve allocative efficiency?

When plasma television sets were first introduced prices were high and few firms were in the market. Later, economic profits attracted new firms and the price of plasma televisions fell. This example illustrates

The minimum point on the average variable cost curve is called

Figure 12-9 Figure 12-9 shows cost and demand curves facing a profit-maximizing, perfectly competitive firm. -If total variable cost exceeds total revenue at all output levels, a perfectly competitive firm

If the market price is $25, the average revenue of selling five units is

If the market price is $25 in a perfectly competitive market, the marginal revenue from selling the fifth unit is

Use a graph to show the demand, AVC, ATC, MC, and MR curves of a firm that should temporarily shut down in the short run. Identify the shutdown point on the graph.

Figure 12-10 -Refer to Figure 12-10. Total revenue at the profit-maximizing level of output is

Figure 12-1 -Refer to Figure 12-1. If the firm is producing 500 units,
