Exam 10: Perfect Competition

The figure given below shows the demand and cost curves of a perfectly competitive firm.Figure: 10.4 D: Demand curve MC: Marginal cost curve ATC: Average-total cost curve AVC: Average-variable-cost curve -According to Figure 10.4, the firm's shutdown price is:

The figure given below shows the revenue and cost curves of a perfectly competitive firm.Figure 10.5 MC: Marginal cost curve MR: Marginal revenue curve.ATC: Average-total-cost curve AVC: Average-variable-cost curve -A firm should not necessarily shut down if:

The figure given below shows the aggregate demand and supply curves of a perfectly competitive market.Figure 10.7 -If the market price falls below the average-variable-cost, the firm will suspend production.

The following figure shows equilibrium at the industry and firm level.Figure 10.6 In the figure, S₁, S₂, S₃ are the market supply curves.D₁ and D₂ are the market demand curves.MC is the marginal cost curve of the firm.MR₁ and MR₂ are the marginal revenue curves of the firm.ATC is the average-total-cost curve of the firm. -According to Figure 10.6, if the market price was $1.50, the individual firm would:

The figure given below shows the revenue and cost curves of a perfectly competitive firm.Figure 10.5 MC: Marginal cost curve MR: Marginal revenue curve.ATC: Average-total-cost curve AVC: Average-variable-cost curve -According to Figure 10.5, the firm has:

The figure given below shows the aggregate demand and supply curves of a perfectly competitive market.Figure 10.7 -Refer to Figure 10.7 and calculate the producer surplus.

The following figure shows equilibrium at the industry and firm level.Figure 10.6 In the figure, S₁, S₂, S₃ are the market supply curves.D₁ and D₂ are the market demand curves.MC is the marginal cost curve of the firm.MR₁ and MR₂ are the marginal revenue curves of the firm.ATC is the average-total-cost curve of the firm. -Since a firm is willing to sell its product at the marginal cost and since the firm receives the market price, the difference between the two is:

The figure given below shows the aggregate demand and supply curves of a perfectly competitive market.Figure 10.7 -The theory of the long-run in perfect competition helps to provide a rationale for the belief in a limited role for government in society.

The figure given below shows the revenue and the cost curves of a perfectly competitive firm.Figure 10.3 -Refer to Figure 10.3 and identify the price level at which the firm earns normal profit.

The table given below shows the total revenue and total cost of a firm at different levels of output.Table 10.2 -Consider the perfectly competitive firm described in Table 10.2. How many units of the good should the firm produce to maximize profit?

The table given below shows the total revenue and total cost of a firm at different levels of output.Table 10.2 -To maximize profits in the short run, a perfectly competitive firm will produce the output at which:

The figure given below shows the revenue and cost curves of a perfectly competitive firm.Figure 10.5 MC: Marginal cost curve MR: Marginal revenue curve.ATC: Average-total-cost curve AVC: Average-variable-cost curve -Since the beginning of the millennium, the United States has witnessed closure of many Internet start-up companies. According to the model of perfect competition, these companies must have shut down in the short run because:

Scenario 9.2 Consider a publicly held firm (one whose stock shares are traded on the stock exchange) that earned revenue worth $350 million and incurred land, labor, and debt costs worth $320 million. The stockholders who have invested a total of $100 million in this firm could have earned 10 percent return on other comparable investments. -A perfectly competitive producer's demand curve is:

The figure given below shows the aggregate demand and supply curves of a perfectly competitive market.Figure 10.7 -Refer to Figure 10.7 and calculate the consumer surplus.

The figure given below shows the aggregate demand and supply curves of a perfectly competitive market.Figure 10.7 -When a perfectly competitive firm's demand curve lies above its average total cost curve, the firm incurs an economic loss at that level of output.

The figure given below shows the revenue and cost curves of a perfectly competitive firm.Figure 10.5 MC: Marginal cost curve MR: Marginal revenue curve.ATC: Average-total-cost curve AVC: Average-variable-cost curve -Under perfect competition, entry of new firms into the market in the long run tends to:

The figure given below shows the revenue and cost curves of a perfectly competitive firm.Figure 10.1 -In Figure 10.1, the firm's profit is equal to the area:

The figure given below shows the revenue and cost curves of a perfectly competitive firm.Figure 10.5 MC: Marginal cost curve MR: Marginal revenue curve.ATC: Average-total-cost curve AVC: Average-variable-cost curve -In the short-run, a competitive firm is said to break-even if at equilibrium the:

The figure given below shows the aggregate demand and supply curves of a perfectly competitive market.Figure 10.7 -Under perfect competition, existing firms leave the market in the long run if the price falls below total fixed cost.

The figure given below shows the revenue and cost curves of a perfectly competitive firm.Figure 10.5 MC: Marginal cost curve MR: Marginal revenue curve.ATC: Average-total-cost curve AVC: Average-variable-cost curve -If a profit-maximizing, perfectly competitive firm is making only a normal profit in the short run, then the firm is in:
