Figure 13-3

38) Refer to Figure 13-3.  The marginal revenue from one additional unit sold is the sum of the gain in revenue from selling the additional unit and the loss in revenue from having to charge a lower price to sell the additional unit. Based on the diagram in the figure,

A) X represents the gain (price effect) and Y the loss (output effect).

B) X + Z represents the loss (output effect) and Y the gain (price effect).

C) Y represents the gain (output effect) and X the loss (price effect).

D) X represents the loss (price effect) and Y + Z the gain (output effect).

B) P = MR > AR.

C) P = AR > MR.

D) P > MR = AR.

41) The Jeans Store sells 7 pairs of jeans per day when it charges $100 per pair. It sells 8 pairs of jeans per day at a price of $90 per pair. The marginal revenue of the eighth pair of jeans is

A) $20.

B) $90.

C) $100.

D) $700.

42) Which of the following describes a difference between the marginal revenue and demand curves of a perfectly competitive firm and a monopolistically competitive firm?

A) The perfectly competitive firm’s marginal revenue and demand curves are the same; the marginal revenue curve of a monopolistically competitive firm lies above its demand curve.

B) The perfectly competitive firm’s marginal revenue and demand curves are the same; the marginal revenue curve of a monopolistically competitive firm lies below its demand curve.

C) The monopolistically competitive firm’s marginal revenue and demand curves are the same; the marginal revenue curve of a perfectly competitive firm lies below its demand curve.

D) The marginal revenue curve of a monopolistically competitive firm lies below its demand curve; the marginal revenue curve of a perfectly competitive firm lies above its demand curve.

43) When a firm faces a downward-sloping demand curve, marginal revenue

A) must exceed price because the price effect outweighs the output effect.

B) is less than price because a firm must lower its price to sell more.

C) equals price because the firm sells a standardized product.

D) must exceed price because the output effect outweighs the price effect.

44) The marginal revenue of a monopolistically competitive firm

A) cannot be negative because the price the firm charges will always be greater than zero.

B) can be negative if the firm charges a high price.

C) can be negative if the firm charges a low price.

D) will equal average revenue.

45) If a monopolistically competitive firm lowers its price and, as a result, its total revenue decreases then

A) the output effect of the price change was less than the price effect.

B) the output effect of the price change was greater than the price effect.

C) the firm’s demand curve must have decreased.

D) the substitution effect of the price change was greater than the income effect.

46) The demand curve of a monopolistically competitive firm

A) is horizontal because the firm must cut its price to sell more.

B) is perfectly elastic.

C) is downward sloping because it sells an identical product.

D) is downward sloping because it must cut its price to sell more.
