Exam 12: Firms in Perfectly Competitive Markets

Figure 12-5 Figure 12-5 shows cost and demand curves facing a typical firm in a constant-cost, perfectly competitive industry. -Refer to Figure 12-5.The firm's manager suggests that the firm's goal should be to maximize average profit.If the firm does this,what is the amount of profit that it will earn?

Figure 12-13 -Refer to Figure 12-13.If the market price is P₁,what is the allocatively efficient output level?

Figure 12-6 Figure 12-6 shows cost and demand curves facing a profit-maximizing, perfectly competitive firm. -Refer to Figure 12-6.At price P₁,the firm would

Figure 12-6 Figure 12-6 shows cost and demand curves facing a profit-maximizing, perfectly competitive firm. -Refer to Figure 12-6.Identify the short-run shut down point for the firm.

Apple introduced its iPhone 3G in July 2008 and within a month sales had topped 3 million units.By April 2009,more than 25,000 apps for the iPhone 3G were available in the iTunes store,an indication that in a competitive market

Suppose Veronica sells teapots in the perfectly competitive teapot market.Her output per day and her costs are as follows: Suppose the current equilibrium price in the teapot market is $20.To maximize profit,how many teapots will Veronica produce,what price will she charge,and how much profit (or loss)will she make? Draw a graph to illustrate your answer.Your graph should include Veronica's demand,ATC,AVC,MC,and MR curves,the price she is charging,the quantity she is producing,and the area representing her profit (or loss).

If a firm in a perfectly competitive industry introduces a lower-cost way of producing an existing product,the firm will be able to earn economic profits in the long run.

Figure 12-6 Figure 12-6 shows cost and demand curves facing a profit-maximizing, perfectly competitive firm. -Refer to Figure 12-6.Identify the firm's short-run supply curve.

If total variable cost exceeds total revenue at all output levels,a perfectly competitive firm

Firms in perfect competition produce the allocatively efficient output in the short run and in the long run.

Figure 12-6 Figure 12-6 shows cost and demand curves facing a profit-maximizing, perfectly competitive firm. -Refer to Figure 12-6.At price P₃,the firm would

Figure 12-4 Figure 12-4 shows the cost and demand curves for a profit-maximizing firm in a perfectly competitive market. -Refer to Figure 12-4.If the market price is $30,the firm's profit-maximizing output level is

Figure 12-2 -Refer to Figure 12-2.What happens if the firm produces more than Q₄ units?

Assume that price is greater than average variable cost.If a perfectly competitive seller is producing at an output where price is $11 and the marginal cost is $14.54,then to maximize profits the firm should

An increase in demand for U.S.farm exports will ________ the market prices for these exports and ________ economic profit in these markets.

Figure 12-4 Figure 12-4 shows the cost and demand curves for a profit-maximizing firm in a perfectly competitive market. -Refer to Figure 12-4.If the market price is $30 and if the firm is producing output,what is the amount of its total variable cost?

If a firm shuts down in the short run,

Figure 12-6 Figure 12-6 shows cost and demand curves facing a profit-maximizing, perfectly competitive firm. -Refer to Figure 12-6.At price P₂,the firm would

Figure 12-9 -Refer to Figure 12-9.Suppose the prevailing price is P₁ and the firm is currently producing its loss-minimizing quantity.In the long-run equilibrium,

Suppose Veronica sells teapots in the perfectly competitive teapot market.Her output per day and her costs are as follows: Suppose the current equilibrium price in the teapot market is $15.To maximize profit,how many teapots will Veronica produce,what price will she charge,and how much profit (or loss)will she make? Draw a graph to illustrate your answer.Your graph should include Veronica's demand,ATC,AVC,MC,and MR curves,the price she is charging,the quantity she is producing,and the area representing her profit (or loss).
