Exam 13: Firms in Competitive Markets

A profit-maximizing firm in a competitive market is able to sell its product for $7. At its current level of output, the firm's average total cost is $10. The firm's marginal cost curve crosses its marginal revenue curve at an output level of 9 units. The firm experiences a

In a perfectly competitive market, the market supply curve is

Which of the following represents the firm's short-run condition for shutting down?

Table 14-11 Suppose that a firm in a competitive market faces the following prices and costs: -Refer to Table 14-11. The marginal revenue from producing the 3rd unit equals i) $6. Ii) the price. Iii) the marginal cost.

Table 14-11 Suppose that a firm in a competitive market faces the following prices and costs: -Refer to Table 14-11. Marginal revenue equals marginal cost when the firm produces

When a restaurant stays open for lunch service even though few customers patronize the restaurant for lunch, which of the following principles is are) best demonstrated? i) Fixed costs are sunk in the short run. Ii) In the short run, only fixed costs are important to the decision to stay open for lunch. Iii) If revenue exceeds variable cost, the restaurant owner is making a smart decision to remain open for lunch.

In making a short-run profit-maximizing production decision, the firm must consider both fixed and variable cost.

Table 14-3 The table represents a demand curve faced by a firm in a competitive market. -Refer to Table 14-3. For this firm, the average revenue is

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

A profit-maximizing firm in a competitive market will always make marginal adjustments to production as long as

If the market elasticity of demand for potatoes is -0.3 in a perfectly competitive market, then the individual farmer's elasticity of demand

Phil sells duck calls in a perfectly competitive market. If duck calls sell for $10 each and average total cost per unit is $11 at the profit-maximizing output level, then in the long run

Table 14-9 Suppose that a firm in a competitive market faces the following revenues and costs: -Refer to Table 14-9. In order to maximize profit, the firm will produce a level of output where marginal revenue is equal to

When determining whether to shut down in the short run, a competitive firm should ignore i) fixed costs. Ii) variable costs. Iii) sunk costs.

When firms are neither entering nor exiting a perfectly competitive market,

Scenario 14-1 Assume a certain firm in a competitive market is producing Q = 1,000 units of output. At Q = 1,000, the firm's marginal cost equals $15 and its average total cost equals $11. The firm sells its output for $12 per unit. -Refer to Scenario 14-1. At Q = 999, the firm's total costs equal

Figure 14-14 -Refer to Figure 14-14. Suppose a firm in a competitive market, like the one depicted in panel a), observes market price rising from P1 to P2. Which of the following could explain this observation?

Comparing marginal revenue to marginal cost i) reveals the contribution of the last unit of production to total profit. Ii) is helpful in making profit-maximizing production decisions. Iii) tells a firm whether its fixed costs are too high.

Figure 14-7 -Refer to Figure 14-7. In the short run, the firm's maximum profit or minimum loss) is the same at which of the following pairs of prices?

Which of the following statements is correct regarding a firm's decision-making?
