Exam 10: Firms in Perfectly Competitive Markets

In a graph with output on the horizontal axis and total revenue on the vertical axis, what is the shape of the total revenue curve for a perfectly competitive seller?

Figure 10.2 -Refer to Figure 10.2.Why is the total revenue curve a ray from the origin?

Figure 10.6 Figure 10.6 shows cost and demand curves facing a profit-maximizing, perfectly competitive firm. -Refer to Figure 10.6.At price P₁, the firm would

Which of the following is not true for a firm in perfect competition?

If a perfectly competitive firm's price is above its average total cost, the firm

The market demand curve for a perfectly competitive industry is the horizontal summation of each individual firm's demand curve.

If, for a given output level, a perfectly competitive firm's price is less than its average variable cost, the firm

Figure 10.5 Figure 10.5 shows cost and demand curves facing a typical firm in a constant-cost, perfectly competitive industry. -Refer to Figure 10.5.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?

If total revenue exceeds fixed cost, a firm

In August 2008, Ethan Nicholas developed the iShoot application for the apple iPhone 3G, and within five months had earned $800,000 from this program.By May 2009, Nicholas had dropped the price from $4.99 to $1.99 in an attempt to maintain sales.This example indicates that in a competitive market,

Which of the following is not a characteristic of a monopolistically competitive market structure?

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

A perfectly competitive firm earns a profit when price is

Figure 10.6 Figure 10.6 shows cost and demand curves facing a profit-maximizing, perfectly competitive firm. -Refer to Figure 10.6.Identify the firm's short-run supply curve.

In the short run, if a firm shuts down its maximum loss equals the amount of its fixed cost.

Figure 10.1 -Refer to Figure 10.1.If the firm is producing 700 units,

A perfectly competitive firm's marginal revenue curve is downward sloping.

Figure 10.9 -Refer to Figure 10.9.Suppose the prevailing price is P₁ and the firm is currently producing its loss-minimizing quantity.In the long-run equilibrium,

If in the long run a firm makes zero profit, it should exit the industry.
