Question 2

Which of the following is not a characteristic of a monopolistically competitive firm in long-run equilibrium?
A) Marginal revenue is equal to marginal cost.
B) Price is equal to average revenue.
C) The firm has excess capacity.
D) Price is equal to marginal cost.

Accepted Answer

In long-run equilibrium, a monopolistically competitive firm will not produce at marginal cost because it has market power and may charge a price higher than marginal cost. Therefore, price will be greater than marginal cost.

Question 3

If a monopolistically competitive firm has excess capacity,
A) it has exhausted all economies of scale.
B) it is producing beyond the minimum efficient scale.
C) it is experiencing diseconomies of scale.
D) it produces an output rate that places it on the negatively sloped portion of its average total cost curve.

Accepted Answer

In monopolistic competition, firms have excess capacity because they produce less than the output level that minimizes average total cost, placing them on the negatively sloped portion of the ATC curve.

Question 4

-Refer to Figure 10-18. The diagram demonstrates that A) in the short run, the monopolistic competitor produces an output Q_b, but in the long run after it adjusts its capacity, it will produce the allocatively efficient output, Q_a. B) it is not possible for a monopolistic competitor to produce the productively efficient output level, Q_a,because of product differentiation. C) it is possible for a monopolistic competitor to produce the productively efficient output level, Q_a,if it is willing to lower its price from P_bto P_a. D) in the long run, the monopolistic competitor produces the minimum-cost output level, Q_a,but in the short run its output of Q_b is not cost minimising.

-Refer to Figure 10-18. The diagram demonstrates...

Question 5

Economists have long debated whether there is a significant loss of well-being to society in markets that are monopolistically competitive rather than perfectly competitive. Which of the following offers the best reason why some economists believe that monopolistically competitive markets are less efficient than perfectly competitive markets?
A) In contrast to perfectly competitive markets, neither allocative efficiency nor productive efficiency are achieved in monopolistically competitive markets.
B) In contrast to perfectly competitive markets, firms in monopolistically competitive markets earn economic profits in long-run equilibrium.
C) In contrast to perfectly competitive markets, firms in monopolistically competitive markets do not produce where price equals average total cost in long-run equilibrium.
D) In contrast to perfectly competitive markets, firms in monopolistically competitive markets can charge a price greater than average total cost in the short run.

Accepted Answer

Monopolistically competitive markets are characterized by product differentiation, meaning firms are not selling identical products. This leads to excess capacity, meaning that firms are not producing at the minimum efficient scale. In addition, because each firm has some degree of control over the price of its product, there is a potential for allocative inefficiency, meaning that resources are not allocated to the most valued use. These factors can lead to a loss of well-being to society compared to perfectly competitive markets where allocative and productive efficiency are achieved.

Question 6

In the long run, firms in both monopolistically competitive markets and perfectly competitive markets earn zero economic profits, but unlike perfectly competitive firms in the long run, monopolistically competitive firms
A) charge a price that is greater than average revenue.
B) charge a price that is equal to marginal cost.
C) do not produce at minimum average total cost.
D) charge a price that is equal to average total cost.

Accepted Answer

In the long run, monopolistically competitive firms do not produce at minimum average total cost because they have some degree of market power and are able to charge a price higher than the marginal cost in order to differentiate their product from competitors. However, in a perfectly competitive market, firms must produce at minimum average total cost in order to survive in the long run as they cannot charge a price higher than the market price.

Question 7

In long-run equilibrium, compared to a perfectly competitive market, a monopolistically competitive industry produces a ________ level of output and charges a ________ price.
A) higher; lower
B) lower; lower
C) lower; higher
D) higher; higher

Accepted Answer

In long-run equilibrium, monopolistically competitive firms will produce a lower level of output than perfectly competitive firms, as they do not achieve the minimum efficient scale. However, they will charge a higher price than perfectly competitive firms due to the differentiation of their products and the market power they have. Therefore, option C is the correct answer.

Question 8

-Refer to Figure 10-17. What is the amount of excess capacity? A) Q_h - Q_f units B) Q_j - Q_f units C) Q_j - Q_h units D) Q_h - Q_g units

Question 9

In contrast with perfect competition, excess capacity characterises monopolistic competition. Excess capacity is due to which of the following?
A) Monopolistically competitive firms produce at the minimum point on their average total cost curves.
B) Monopolistically competitive firms face downward-sloping demand curves. In the long run, firms produce where their demand curves are tangent to their long-run average total cost curves.
C) Monopolistically competitive firms produce where marginal revenue is equal to marginal cost.
D) Monopolistically competitive markets have low barriers to entry.

Accepted Answer

Excess capacity in monopolistic competition is due to firms producing where their demand curves are tangent to their long-run average total cost curves, which is a characteristic of monopolistic competition that distinguishes it from perfect competition. In perfect competition, firms produce at a point where there is no excess capacity. Choices A, C, and D do not adequately explain the presence of excess capacity in monopolistic competition.

Question 10

Long-run equilibrium in a monopolistically competitive market is similar to long-run equilibrium in a perfectly competitive market in that in both markets, firms
A) produce at the minimum point of their average total cost curves.
B) produce where price equals marginal cost.
C) break even.
D) produce where price equals marginal revenue.

Accepted Answer

Question 11

Economists have long debated whether there is a significant loss of well-being to society in markets that are monopolistically competitive rather than perfectly competitive. Which of the following offers the best reason why some economists believe that monopolistically competitive markets benefit consumers despite any loss of well-being?
A) Although consumers may pay a price greater than marginal cost for a product, the product is produced at the minimum average total cost.
B) Although consumers may pay a price greater than marginal cost and the product is not produced at minimum average total cost, they benefit from being able to buy a differentiated product more closely suited to their tastes.
C) Consumers pay a price equal to the marginal cost of producing a product, even though it is not produced at the minimum average total cost.
D) Consumers are better off choosing from a variety of differentiated products, even though product differentiation causes barriers that restrict entry into monopolistically competitive markets.

Accepted Answer

This choice explains that while consumers may pay a higher price and the product may not be produced at minimum average total cost, they benefit from having access to a differentiated product that better suits their tastes. This differentiation can justify the higher price and may ultimately benefit the consumer, despite any loss of well-being from a less perfectly competitive market.

Question 12

-Refer to Figure 10-17. Suppose the firm is currently producing Q_f units. What happens if it increases its output to Q_gunits? A) Its average cost of production will fall and its profit will rise. B) It will be taking advantage of economies of scale and will be able to lower the price of its product. C) It will move from a zero profit situation to a profit situation D) It will move from a zero profit situation to a loss situation

Accepted Answer

Without seeing Figure 10.17, we can infer from the question that increasing output leads to a situation where the firm moves from a zero profit situation to a loss situation. This implies that the additional units produced increase costs more than revenues, leading to losses.

Question 13

Compared to a perfectly competitive firm, the demand curve facing a monopolistically competitive firm is
A) more elastic because there are many close substitutes for the product of a monopolistically competitive firm.
B) less elastic because monopolistically competitive firms produce similar, but not identical, products.
C) just as elastic because there are many sellers in both markets.
D) more elastic because in the long run, the demand curve is tangent to the firm's average total cost curve.

Accepted Answer

Monopolistically competitive firms produce products that are similar but not identical, so their demand curve is less elastic compared to a perfectly competitive firm. The close substitutes available in the market make consumers more likely to switch to a competitor if the monopolistically competitive firm increases its price, but not all consumers will switch to another firm due to the differentiation in products.

Question 14

Only one of the following statements is correct. The statements compare perfectly competitive (PC) markets and monopolistically competitive (MC) markets. Which statement is correct?
A) Productive efficiency is achieved in both PC and MC markets. Allocative efficiency is achieved only in MC markets.
B) Allocative efficiency is achieved in both PC and MC markets. Productive efficiency is achieved only in PC markets.
C) Productive efficiency and allocative efficiency are both achieved in PC markets. Neither is achieved in MC markets.
D) Allocative efficiency is achieved only in PC markets. Productive efficiency is achieved only in MC markets.

Accepted Answer

The answer of Only one of the following statements is...

Question 15

-Refer to Figure 10-17. In the long run, why will the firm produce Q_f units and not Q_gunits, which has a lower average cost of production? A) Although its average cost of production is lower when the firm produces Q_gunits, to be able to sell its output the firm will have to charge a price below average cost, resulting in a loss. B) At Q_g, average cost exceeds marginal cost so the firm will actually incur a loss. C) At Q_g, marginal revenue is less than average revenue, which will result in a loss for the firm. D) The firm's goal is to charge a high price and make a small profit rather than charge a low price and make no profit.

Accepted Answer

Although Q_g has a lower average cost of production, the firm would have to charge a price below average cost, which will result in a loss. Therefore, Q_f is the optimal production level in the long run.

Question 16

Excess capacity is a characteristic of monopolistically competitive firms. What does excess capacity mean?
A) It means that firms do not produce the output level that corresponds to the minimum point on their average total cost curves.
B) It means that firms hire more than the minimum number of workers needed to produce the profit-maximising level of output.
C) It means that firms produce with inefficient combinations of resources.
D) It means that firms build plants that are not large enough to achieve minimum efficient scale.

Accepted Answer

Excess capacity in monopolistically competitive firms refers to their operation at a level of output where they do not achieve the lowest possible average total cost, which is not producing at the minimum point on their average total cost curves.

Question 17

In what way does long-run equilibrium under monopolistic competition differ from long-run equilibrium under perfect competition?
A) Firms in perfect competition achieve productive and allocative efficiency while firms in monopolistic competition achieve neither allocative nor productive efficiency.
B) The only difference is that in a monopolistically competitive market there are many brands to choose from while in a perfectly competitive market there is one standard product.
C) Firms in perfect competition achieve productive efficiency while firms in monopolistic competition achieve allocative efficiency.
D) Firms in perfect competition achieve allocative efficiency while firms in monopolistic competition achieve brand efficiency.

Accepted Answer

In perfect competition, firms achieve both productive and allocative efficiency, while in monopolistic competition, firms achieve neither productive nor allocative efficiency. This is because firms in monopolistic competition have some control over the price they charge due to product differentiation, which leads to excess capacity and higher prices compared to perfect competition.

Question 18

Which of the following statements is true about monopolistically competitive firms?
A) Unlike perfectly competitive firms, monopolistically competitive firms are able to raise their prices without losing all of their customers.
B) Like perfectly competitive firms, monopolistically competitive firms are not able to raise prices without losing all of their customers because they face competition from firms selling similar products.
C) Like perfectly competitive firms, monopolistically competitive firms maximise their profits by settling price equal to marginal cost.
D) Unlike perfectly competitive firms, monopolistically competitive firms face perfectly inelastic demand curves.

Accepted Answer

Monopolistically competitive firms have some degree of market power due to product differentiation, allowing them to raise prices without losing all customers, unlike perfectly competitive firms which are price takers and would lose customers if they tried to raise prices above the market level.

Question 19

Monopolistically competitive firms have downward-sloping demand curves. In the long run, monopolistically competitive firms earn zero economic profits. These two characteristics imply that in the long run
A) monopolistically competitive markets achieve productive efficiency.
B) monopolistically competitive markets achieve allocative efficiency.
C) monopolistically competitive firms earn economic profits.
D) monopolistically competitive firms have excess capacity.

Accepted Answer

Monopolistically competitive firms have excess capacity in the long run because they produce at a quantity lower than the one that would minimize their average total cost. This is due to the downward-sloping demand curve, which makes them have a markup over their marginal cost, similar to a monopoly. However, unlike a monopoly, monopolistically competitive firms face competition from other firms producing close substitutes, which erodes their ability to earn economic profits in the long run. As a result, they operate with excess capacity in the long run, which implies that they could produce more and increase their profits, but they don't because they face insufficient demand for their products at higher prices.

Question 20

-Refer to Figure 10-18. Which of the following statements is true? A) D_arepresents the long-run demand curve facing a monopolistic competitor in a constant-cost industry while D_bdepicts the demand curve in the short run. B) D_arepresents the long-run demand curve facing a monopolistic competitor in a constant-cost industry while D_bdepicts the long-run demand curve in an increasing-cost industry. C) D_arepresents the long-run demand curve facing a perfect competitor while D_bdepicts the long-run demand curve facing a monopolistic competitor. D) D_arepresents the long-run supply curve in a perfectly competitive, constant-cost industry while D_bdepicts the long-run demand curve facing a monopolistic competitor in a decreasing-cost industry.
