Question 1

The typical firm in the US economy

Accepted Answer

The typical firm in the US economy has some degree of market power, meaning that it has the ability to influence the price of its product or service. This could be due to brand recognition, patents, or other factors that differentiate it from its competitors. It is not perfectly competitive, where there are many firms producing identical products with no market power, and it is not a monopoly, where there is only one firm with complete market power. The typical firm also does not sell its product for a price equal to marginal cost, as it seeks to maximize profits by pricing above marginal cost.

Question 2

Which of the following is not an example of Joel Waldfogel's "Tyranny of the Market"?

Accepted Answer

Joel Waldfogel's "Tyranny of the Market" refers to situations where market outcomes favor the majority, often at the expense of minority preferences. Nike creating specialized shoes for American Indians' wider feet is an example of catering to a minority group, not ignoring them, thus it does not fit the concept.

Question 3

​A monopolistically competitive firm is currently charging a price of $10 and producing 12,000 units/month. It faces monthly fixed costs of $15,000 and has an average variable cost of $6/unit. In the long run, we would expect:

Accepted Answer

The answer of ​A monopolistically competitive firm is currently charging...

Question 4

The two types of imperfectly competitive markets are

Accepted Answer

The two types of imperfectly competitive markets are monopolistic competition and oligopoly. Monopoly is a type of market structure where a single firm produces and sells the product with no close substitutes, while oligopoly is a market structure where a few firms dominate the market. Monopolistic competition is a market structure with many firms selling differentiated products that are close substitutes, while oligopoly is a market structure with a small number of firms dominating the market. Therefore, the correct answer is C.

Question 5

In a market that is characterized by imperfect competition,

Accepted Answer

In a market with imperfect competition, there are at least a few firms that compete with one another. This means that the actions of one firm can have an impact on the profits of other firms. Firms may have some market power and may not be price takers like in a perfectly competitive market. The number of firms in the market can vary but does not have to be large.

Question 6

Which of the following statements is not correct?

Accepted Answer

This statement is not correct because perfect competition is characterized by homogenous products, meaning all firms produce identical products. Monopolistic competition, on the other hand, is characterized by product differentiation, which allows firms to charge slightly different prices for their products. Therefore, only statement D is incorrect. A, B, and C are all correct statements about monopolistic competition and other market structures.

Question 7

A typical firm in the US economy would be classified as

Accepted Answer

The US economy is dominated by imperfectly competitive markets, with a few large firms having significant market power. This is reflected in industries such as tech (Apple, Microsoft, Google), airlines (Delta, United, American), and telecom (AT&T, Verizon). While there are examples of duopolies (Coca-Cola and Pepsi in the soft drink industry) and oligopolies (automakers), these are the exception rather than the norm. Therefore, choice B is the best classification for a typical firm in the US economy.

Question 8

In a monopolistically competitive market,

Accepted Answer

In a monopolistically competitive market, the entry of new firms can create externalities, such as increased product variety for consumers and increased competition, which can affect existing firms' profits.

Question 9

In what way is monopolistic competition less beneficial to the welfare of society in the long run? ​

Accepted Answer

In monopolistic competition, firms do not produce at the minimum point of the average total cost curve in the long run, leading to excess capacity and inefficiency, which is less beneficial to societal welfare.

Question 10

Although monopolistically competitive markets offer consumers a wide variety of differentiated products, there may still be insufficient variety if

Accepted Answer

Large fixed costs can create barriers to entry, which can limit the number of firms in the market and reduce the variety of products available to consumers.

Question 11

The product-variety externality arises in monopolistically competitive markets because

Accepted Answer

In monopolistically competitive markets, firms try to differentiate their products in order to attract customers and create brand loyalty. This creates a product-variety externality, as each firm's decisions regarding product differentiation affects the demand and profitability of other firms in the market.

Question 12

Firms in industries that have competitors but do not face so much competition that they are price takers are operating in either a(n)

Accepted Answer

In an oligopoly market, there are only a few dominant firms that control the market and can influence prices. In a monopoly market, there is only one firm that controls the market and sets prices. In a perfectly competitive market, there are many small firms that cannot influence prices. Therefore, the only option left is a monopolistically competitive market, where firms have some market power but still face competition from other firms.

Question 13

The general term for market structures that fall somewhere between monopoly and perfect competition is

Accepted Answer

Imperfectly competitive markets is the general term for market structures that are not perfectly competitive or monopolistic, including oligopoly and monopolistic competition.

Question 14

Entry by new firms into a monopolistically competitive market

Accepted Answer

Entry by new firms into a monopolistically competitive market increases product variety, which can enhance consumer surplus by providing more choices and potentially lowering prices.

Question 15

Imperfectly competitive firms are characterized by

Accepted Answer

Imperfectly competitive firms have the ability to set their own prices, unlike firms in perfectly competitive markets, which are price takers. This means that they have some degree of market power and can influence the market price.

Question 16

Which of the following statements is not correct?

Accepted Answer

Monopolistic competition is characterized by free entry and exit, unlike oligopoly, which has barriers to entry.

Question 17

Which of the following pairs illustrates the two extreme examples of market structures?

Accepted Answer

Perfect competition and monopoly illustrate the two extreme examples of market structures. In perfect competition, there are many firms and no single firm has control over the market price. In monopoly, there is only one firm and it has complete control over the market price. Perfect competition and monopoly are opposite market structures and represent the two extremes in terms of competition and market power.

Question 18

​A monopolistically competitive firm is currently charging a price of $20 and producing 3,000 units/month. It faces monthly fixed costs of $1,000 and has an average variable cost of $22/unit. We would expect:

Accepted Answer

The firm is currently incurring losses since its price of $20 is lower than its average total cost of $22 ($1,000 + $22*3,000 = $67,000 total cost, which gives an average total cost of $22.33). In the short run, the firm should shut down since it cannot even cover its variable costs with its current price. In the long run, other firms may exit the market due to the losses, which could increase demand for the existing firms and allow them to earn economic profits (if demand increases enough to allow them to charge a higher price). However, this is not guaranteed and will depend on the specific market conditions. The firm cannot raise its price to cover its variable costs since the demand curve it faces is downward sloping, meaning that consumers will buy less at higher prices. The firm is also not at minimum efficient scale since it is producing less than the optimal output level for cost minimization.

Question 19

​Deadweight losses are associated with monopolistic competition:

Accepted Answer

Deadweight losses are associated with monopolistic competition in both the short and long run. In the short run, firms can earn profit by setting their price above the marginal cost, leading to a deadweight loss. In the long run, firms continue to earn profit, but the entry of new firms attracts customers away from existing ones, leading to excess capacity and further deadweight loss.

Question 20

The two types of imperfectly competitive markets are

Accepted Answer

Monopolistic competition and oligopoly are the two types of imperfectly competitive markets. Monopolistic competition is characterized by many firms competing by selling differentiated products, whereas oligopoly is a market structure dominated by a few large firms that can influence the market price through strategic behavior. Option A is incorrect because advertising can be present in both monopolistic competition and oligopoly. Option B is incorrect because public goods and common resources are not examples of imperfectly competitive markets. Option C is partially correct, as oligopoly is one of the types, but monopoly alone is not enough to account for all imperfectly competitive markets.
