Exam 14: Firms in Competitive Markets.

Explain how a firm in a competitive market identifies the profit-maximizing level of production.When should the firm raise production,and when should the firm lower production?

Carol owns a running shoe store that operates in a perfectly competitive market.If running shoes sell for $120 per pair and the average total cost per pair of shoes is $125 at the profit-maximizing output level,then in the long run

The long-run equilibrium in a competitive market characterized by firms with identical costs is generally characterized by firms operating at efficient scale.

Sam sells soybeans to a broker in Chicago,Illinois.Because the market for soybeans is generally considered to be competitive,Sam maximizes his profit by choosing

The short-run supply curve for a firm in a perfectly competitive market is

When an individual firm in a competitive market increases its production,it is likely that the market price will fall.

When new firms enter a perfectly competitive market,

Figure 14-2 Suppose a firm operating in a competitive market has the following cost curves: -Refer to Figure 14-2.Which of the four prices corresponds to a firm earning zero economic profits in the short run?

Figure 14-3 Suppose a firm operating in a competitive market has the following cost curves: -Refer to Figure 14-3.If the market price is $10,what is the firm's total cost?

When economic profits are zero in equilibrium,the firm's revenue must be sufficient to cover all opportunity costs.

A profit-maximizing firm in a competitive market is currently producing 200 units of output.It has average revenue of $9 and average total cost of $7.It follows that the firm's

Table 14-10 Suppose that a firm in a competitive market faces the following revenues and costs: -Refer to Table 14-10.Which level of production in the table has the lowest average variable cost?

Table 14-8 Suppose that a firm in a competitive market faces the following revenues and costs: -Refer to Table 14-8.In order to maximize profits,the firm will produce

When an individual firm in a competitive market decreases its production,it is likely that the market price will rise.

When new firms enter a perfectly competitive market,

Figure 14-14 -Refer to Figure 14-14.If the market starts in equilibrium at point C in panel (b),a decrease in demand will ultimately lead to

Figure 14-8 Suppose a firm operating in a competitive market has the following cost curves: -Refer to Figure 14-8.Which line segment best reflects the long-run supply curve for this firm?

If a competitive firm is currently producing a level of output at which marginal cost exceeds marginal revenue,then

Figure 14-3 Suppose a firm operating in a competitive market has the following cost curves: -Refer to Figure 14-3.If the market price is $10,what is the firm's total revenue?

Figure 14-14 -Refer to Figure 14-14.When the market is in long-run equilibrium at point A in panel (b),the firm represented in panel (a)will
