Exam 14: Firms in Competitive Markets

Consider a firm that operates in a perfectly competitive market. Currently the firm is producing 300 units of output and the price is $20. If marginal cost at 300 units is $22, the firm

If a firm in a perfectly competitive market triples the quantity of output sold, then total revenue will

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?

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. To maximize its profit, the firm should

If a firm operating in a competitive industry shuts down in the short run, it can avoid paying

Figure 14-9 Suppose a firm operating in a competitive market has the following cost curves: -Refer to Figure 14-9. Which line segment best reflects the long-run supply curve for this firm?

A firm in a competitive market has the following cost structure: What is the lowest price at which this firm might choose to operate?

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.

Changes in the output of a perfectly competitive firm, without any change in the price of the product, will change the firm's

Suppose that a competitive market is initially in equilibrium. Then demand increases. If entering firms face the same costs as existing firms and sufficient resources are available for entering firms,

In a competitive market the current price is $5. The typical firm in the market has ATC = $5.50 and AVC = $4.50.

Figure 14-8 Suppose a firm operating in a competitive market has the following cost curves: -Refer to Figure 14-8. Which segment of the supply curve represents the firm shutting down?

Scenario 14-2 Assume a certain firm is producing Q = 1,000 units of output. At Q = 1,000, the firm's marginal cost equals $20 and its average total cost equals $25. The firm sells its output for $30 per unit. -Refer to Scenario 14-2. At Q = 999, the firm's total costs equal

​A restaurant, which operates in a perfectly competitive market, is evaluating whether it should serve breakfast on a daily basis. It would choose to do this when its revenues cover its variable costs.

In the long run with free entry and exit and identical firms, are competitive firms' profits positive, zero, or negative?
