Exam 13: Firms in Competitive Markets

Table 14-5 The table represents a demand curve faced by a firm in a competitive market. -Refer to Table 14-5. For this firm, the average revenue when 14 units are produced and sold is

By comparing the marginal revenue and marginal cost from each unit produced, a firm in a competitive market can determine the profit-maximizing level of production.

Figure 14-14 -Refer to Figure 14-14. Assume that the market starts in equilibrium at point W in panel b) and that panel a) illustrates the cost curves facing individual firms. Suppose that demand increases from D0 to D1. Which of the following statements is not correct?

When a profit-maximizing firm's fixed costs are considered sunk in the short run, then the firm

Suppose a firm in each of the two markets listed below were to increase its price by 15 percent. In which pair would the firm in the first market listed experience a dramatic decline in sales, but the firm in the second market listed would not?

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?

Which of the following statements is not correct?

A firm in a competitive market has the following cost structure: If the market price is $16, this firm will

Figure 14-9 In the figure below, panel a) depicts the linear marginal cost of a firm in a competitive market, and panel b) depicts the linear market supply curve for a market with a fixed number of identical firms. -Refer to Figure 14-9. When 100 identical firms participate in this market, at what price will 15,000 units be supplied to this market?

Because there are many sellers in a competitive market, individual firms are unable to maximize profits.

Use a graph to demonstrate the circumstances that would prevail in a perfectly competitive market where firms are experiencing economic losses. Identify costs, revenue, and the economic losses on your graph. Using your graph, determine whether an individual firm will shut down in the short run, or choose to remain in the market. Explain your answer.

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 short­run economic profit?

Whenever a perfectly competitive firm chooses to change its level of output, its marginal revenue

We can measure the profits earned by a firm in a competitive industry as

A firm operating in a perfectly competitive industry will continue to operate in the short run but earn losses if the market price is less than that firm's average total cost but greater than the firm's average variable cost.

Which of the following is not a characteristic of a competitive market?

Which of the following statements regarding a competitive firm is correct?

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

Suppose a firm in a competitive market reduces its output by 20 percent. As a result, the price of its output is likely to

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