Suppose the figure to the right represents the market for a particular brand of​ shampoo, such as​ L'Oreal, Lancome, or Maybelline. Assume the market is monopolistically competitive and is in​ long-run equilibrium. How much excess capacity does the firm​ have? The monopolistically competitive​ firm's excess capacity is ______ thousand bottles of shampoo. ​Instead, suppose the market is perfectly competitive and is in​ long-run equilibrium​ (with the same cost structure as that illustrated in the​ figure.) How much excess capacity does the firm​ have? The perfectly competitive​ firm's excess capacity is ____ thousand bottles of shampoo.

4, = (11-7) 0, = (11-11) Excess​ capacity: Is equal to the difference between the​ profit-maximizing level of output and the productively efficient level of output. The​ long-run equilibrium​ price: In a perfectly competitive market is that price where​ long-run average cost is minimized. In this​ example, this occurs when price equals​ $1.10. Consequently, the firm produces 11 thousand bottles of shampoo. The productively efficient level of​ output: Where production occurs at lowest average total cost. This occurs when 11 thousand bottles of shampoo are produced. ​Therefore, the firm has no excess capacity. In​ general, perfectly competitive firms are productively efficient​ (with no excess​ capacity). Explanations in Notes

Area A

According to the graph, a decrease in price from $3.50 to $3.00 per cup results in a gain and a loss of revenue. Which area represents the gain of revenue?

Area B

How does the entry of new coffeehouses affect the profits of existing​ coffeehouses? A monopolistically competitive firm in a​ long-run equilibrium produces where

Entry will decrease the profits of existing coffeehouses by shifting each of their individual demand curves to the left and making the demand curves more elastic. its demand curve is tangent to its average total cost curve.

What is the term given to all the activities necessary for a firm to sell a product to a consumer?

Marketing

Which type of efficiency is achieved by a monopolistically competitive firm in the long run?

Neither allocative nor productive efficiency

A monopolistically competitive firm​ doesn't produce where P​ = MC like a perfectly competitive firm because

P exceeds MR for a monopolistically competitive​ firm, and​ it's MR that must equal MC for profit maximization. Explanation: All firms use the same fundamental approach to profit​ maximization: they produce where marginal revenue equals marginal cost. For a perfectly competitive​ firm, price equals marginal​ revenue, P​ = MR.​ Therefore, to fulfill the MR​ = MC condition for profit​ maximization, a perfectly competitive firm will produce where P​ = MC. Because P​ > MR for a monopolistically competitive​ firm, which results from the marginal revenue curve being below the demand​ curve,a monopolistically competitive firm will maximize profits where P​ > MC.

There are many wheat farms in the United​ States, and there are also more than​ 2,000 Panera Bread restaurants. ​Why, then, does a Panera Bread restaurant face a​ downward-sloping demand curve when a wheat farmer faces a horizontal demand​ curve?

Wheat is a homogeneous​ good, while Panera Bread is able to differentiate its food from other restaurants.

According to the graph, what will be the firm's total revenue if it is maximizing profits?

$13,500

Which of the following best describes the additional revenue associated with selling an additional unit of output?

Marginal revenue

What are the most important differences between perfectly competitive markets and monopolistically competitive​ markets? Unlike in perfectly competitive​ markets, in monopolistically competitive​ markets, Give two examples of products sold in perfectly competitive markets and two examples of products sold in monopolistically competitive markets.

firms face​ downward-sloping demand​ curves, and the products competitors sell are differentiated. Apples and oranges are sold in perfectly competitive markets and Maybelline cosmetics and Ralph Lauren cologne are sold in monopolistically competitive markets.

According to the graph, what will happen if Starbucks increases the price of caffe lattes?

it will lose some, but not all, of its customers

A monopolistically competitive firm in a long-run equilibrium produces where:

its demand curve is tangent to its average total cost curve

A monopolistically competitive firm produces where:

marginal revenue equals marginal cost

Consider the graph to the right. Is it possible to say whether this firm is a perfectly competitive firm or a monopolistically competitive firm? The graph shows a _______ equilibrium because the firm is making ______ profits. What quantity on the graph represents​ long-run equilibrium if the firm were perfectly​ competitive? ____ burritos per week.

Yes. This is a monopolistically competitive firm because its demand curve is downward sloping. short run, positive 6 (b/c a perfectly competitive firm in the long run will be producing at the lowest average cost. This occurs at the quantity where marginal cost intersects average total cost at its minimum point.)

What trade-offs do consumers face when buying a product from a monopolistically competitive firm?

consumers pay a price greater than marginal cost but also have a wider array of choices

The monopolistically competitive firm sells a __________ product and faces a __________ demand curve.

differentiated, downward-sloping

According to the graph, the firm in question is a monopolistically competitive firm:

in long-run equilibrium as indicated by the equality of price and average cost

A monopolistically competitive firm is characterized by the existence of many firms in the market, differentiated products and:

low barriers to entry

According to the graph, the loss in revenue from decreasing price is greater than the gain in revenue from increasing price whenever marginal revenue is:

negative

For what type of market structure is the demand curve the same as marginal revenue?

perfect competition

If a monopolistically competitive firm's demand curve is above its average total cost curve, then this firm is making:

positive economic profit

Which of the following best describes how the product differentiation of monopolistically competitive firms may benefit consumers?

product differentiation can locate firms more conveniently to consumers and offer versions of a product or service that better fit their needs

A firm may opt to pay millions of dollars for celebrity endorsements in order to:

signal to consumers that the advertised product is appealing and likely to be popular

Monopolistically competitive firms have some control over price because

the products they produce are differentiated. Since the products are not identical, the demand for each firm's goods is elastic, but not perfectly elastic. However, if the firm increases price it will lose some sales as customers switch to competing products and if the firm lowers price it will gain some customers. The barriers to entry are low but that fact has limited impact on pricing. There are large numbers of firms competing in this market structure.

Does the fact that monopolistically competitive markets are not allocatively or productively efficient mean that there is a significant loss in economic​ well-being to society in these​ markets? Though monopolistically competitive markets are not allocatively or productively​ efficient, consumers benefit in that

they are able to purchase a differentiated product that more closely suits their tastes.

Consider the graph at​ right: At the​ profit-maximizing level of​ output, how much economic profit is this firm​ earning? Which of the following statements is​ true? Which of the following statements is​ true?

​Zero, because at the​ profit-maximizing output​ level, the price equals average total cost. The firm is not productively efficient because the​ profit-maximizing price is not at the minimum of average total cost. The firm is not allocatively efficient because the​ profit-maximizing price exceeds marginal cost. Explanations in Notes

In the figure to the​ right, consider the marginal revenue of the eighth unit sold. When the firm cuts the price from $6.00 to $5.60 to sell the eighth unit, the area in the graph denoting the output effect is given by ____ In​ dollars, this effect is ​$ ____ When the firm cuts the price from $6.00 to $5.60 to sell the eighth unit, the area in the graph denoting the price effect is given by _____ The marginal revenue of the eighth unit is therefore equal to $____

C, $ 5.60 (b/c the output effect is the extra revenue from selling one more​ unit, in this case the eighth. Since the price was reduced to $5.60 to sell this​ unit, the additional revenue it​ brings, the output​ effect, must be $5.60.) B, $ 2.80 = (6x7 - 5.6x7) (b/c the price effect is the​ "bad thing" that happens when the firm cuts its price from $6.00 to $5.60. By doing​ so, the firm is receiving $0.40 less for each of the units it previously sold at the original​ (higher) price. In the graph this lost revenue is the price change​ (a "height") times the original amount sold​ (a "base"). The area​ ("height" ×​"base") depicting this is labeled B. $2.80 = (5.6 -2.8) (b/c the marginal revenue of the eighth unit is simply the output effect less the price effect. This gives $5.60−$2.80 ​= $2.80. ​Alternatively, the marginal revenue can be computed as the difference between the total revenue earned from the sale of 8 units ​($44.80​) less the total revenue from the sale of 7 units ​($42.00​). This too gives​ (as it​ must) $2.80.

Suppose Angelica opens a small store near​ campus, selling beef brisket sandwiches. Use the graph to the​ right, which shows the demand and cost for​ Angelica's beef brisket​ sandwiches, to answer the questions that follow. a. If Angelica wants to maximize​ profits, she should sell ____ beef brisket sandwiches per day and charge ​$_____ b. At the above price and quantity she is making an economic profit​ (or loss) of ​$____ c. What is Angelica likely to do in the long​ run?

a. 55 beef brisket sandwiches, charge $4.50. (b/c that is where MC=MR) b. -$55 (b/c Profit/Loss = [(P-ATC)*Quantity] = (4.50-5.50)* 55 = -$55. c. Exit the industry

Maria manages a​ bakery, that specializes in ciabatta​ bread, and has the following information on demand and​ costs: a. To maximize​ profits, Maria should sell _____ loaves of cibatta bread per hour. b. Maria should charge a price of $ c. Maria's maximum profit is ​$ d. The marginal revenue when selling the​ profit-maximizing number of loaves of ciabatta bread is $____ The marginal cost when selling the​ profit-maximizing number of loaves of ciabatta bread is $____.

a. 6 b. $3.00 c. $4.50 d. .50 and .50 To find total​ profit, subtract total cost from total revenue at the​ profit-maximizing level of​ output, which was previously found to be where marginal revenue is equal to marginal cost. Recall that all firms use the same approach to maximize​ profits: They produce where marginal revenue is equal to marginal cost. Find marginal revenue by calculating revenue at each​ quantity, which is equal to P×Q. Find marginal cost using the total cost column. Then find the quantity where marginal revenue equals marginal cost.
