Exam 10: Perfect Competition

The figure given below shows the aggregate demand and supply curves of a perfectly competitive market.Figure 10.7 -Under perfect competition, the per unit revenue of a firm is equal to its marginal revenue.

The figure given below shows the aggregate demand and supply curves of a perfectly competitive market.Figure 10.7 -If at the profit-maximizing level of output, a typical perfectly competitive firm's price is greater than its average total cost, the firm should increase output.

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. -Graphically, consumer surplus is the area:

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 -Some competitive firms are willing to operate at a loss, in the short run, because:

The figure given below shows the revenue and cost curves of a perfectly competitive firm.Figure 10.1 -A firm whose price is below its average cost:

The figure given below shows the revenue and cost curves of a perfectly competitive firm.Figure 10.2 MC: Marginal cost curve MR: Marginal revenue curve ATC: Average-total-cost curve AVC: Average-variable-cost curve -In the short run, a firm continues to produce only if it can cover the:

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 -When revenue is less than total cost but more than variable cost it implies that:

The figure given below shows the aggregate demand and supply curves of a perfectly competitive market.Figure 10.7 -Economic efficiency is achieved when the price of a unit of a commodity is equal to the marginal cost of producing that unit.

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. -Perfect competition describes a firm's behavior in a market model where:

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 calculate the total fixed cost borne by the firm at the profit maximizing level of the output.

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. -Graphically, producer surplus is the area:

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. -One assumption of the model of perfect competition is that entry into the market is easy. This implies that:

The table given below shows the total revenue and total cost of a firm at different levels of output.Table 10.2 -What is the equilibrium price for the perfectly competitive firm described in Table 10.2?

The figure given below shows the aggregate demand and supply curves of a perfectly competitive market.Figure 10.7 -In the long-run, the entry of new firms in a competitive market shifts the aggregate supply curve to the left.

The table given below shows the price of each unit of the product manufactured by a firm and the marginal cost of producing different units of the output.Table: 10.1 -Refer to Table 10.1. If the market price of the good falls to $0.80 per unit, the firm:

The figure given below shows the aggregate demand and supply curves of a perfectly competitive market.Figure 10.7 -Given a perfectly competitive market structure at the profit-maximizing output level, a firm's total fixed cost is $15, total variable cost is $137, marginal revenue is $4, and the quantity demanded is 65. The total profit earned by the firm is $108.

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 calculate the firm's total revenue at the profit maximizing 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 -In the short run, a firm attempting to minimize losses:

The figure given below shows the revenue and cost curves of a perfectly competitive firm.Figure 10.1 -If the price of the output produced by a perfectly competitive firm increases, then:

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. -If market demand increases, a perfectly competitive firm will find:
