• Marginal cost is the cost of producing an additional unit of output.
• A larger firm is more efficient because average cost decreases as output Q increases: internal economies of scale.
• This situation occurs when there are only a few major producers of a particular good or when each firm produces a good that is differentiated from that of rival firms.
• Study why those better-performing firms have a greater incentive to engage in the global economy.
The Theory of Imperfect Competition
• In imperfect competition, firms are aware that they can influence the prices of their products and that they can sell more only by reducing their price.

英文版微观经济学复习提纲Chapter 10. Monopolistic competition
10Monopolistic Competition: The Competitive Model in a More RealisticSettingChapter SummaryMost markets in Australia have many buyers and sellers, low entry barriers and differentiated goods and services for sale. These are characteristics of monopolistic competition. Each monopolistically competitive firm faces a downward-sloping demand curve so marginal revenue is less than price. Firms maximise profit by producing the level of output that makes marginal revenue equal marginal cost. The firm may earn an economic profit or suffer an economic loss in the short run. Since there are low entry barriers, economic profits will cause new firms to enter the market. A firm that earns short-run profits will earn zero economic profit in the long run as entry from new firms shifts the firm’s demand curve to the left and causes it to become more elastic. If a firm suffers economic losses in the short run, other firms will exit the market and shift the firm’s demand curve to the right and cause it to become less elastic. In the long run, the firm’s demand curve will be tangent to its long-run average total cost curve, but average total cost will be greater than its minimum level.Monopolistic competition and perfect competition differ in their long-run equilibrium positions. Monopolistically competitive firms charge a price greater than marginal cost and they do not produce at minimum average total cost. A monopolistically competitive firm has excess capacity. If it increases its output it could produce at a lower average cost. But consumers benefit from being able to purchase a product that is differentiated and more closely suited to their tastes.Firms can use marketing to differentiate their products. Marketing tools include brand management and advertising.Learning ObjectivesWhen you finish this chapter you should be able to:1.Explain why a monopolistically competitive firm has a downward-sloping demand curve.A monopolistically competitive firm is able to raise its price without losing all of its customers.Some customers are willing to pay the higher price because the firm has a favourable location, can offer better service or a higher quality product, among other reasons.2.Explain how a monopolistically competitive firm decides the quantity to produce and theprice to charge. All firms maximise profits by producing where marginal revenue is equal to marginal cost. Since price is greater than marginal revenue, a monopolistically competitive firmMonopolistic competition: the competitive market in a more realistic setting 154 produces where price is greater than marginal cost. The firm will earn economic profits if its price exceeds average total cost in the short run.3.Analyse the situation of a monopolistically competitive firm in the long run. Since entrybarriers are low in monopolistically competitive industries, short-run profits give entrepreneurs an incentive to enter the market and establish new firms. The entry of new firms will shift the demand curves of existing firms to the left and make them more elastic. If firms suffer short-run economic losses, some firms will exit the industry in the long run. This will shift the demand curves of remaining firms to the right and make them more inelastic. In the long run, the demand curve of a typical firm will be tangent to its average total cost curve.pare the efficiency of monopolistic competition and perfect competition. In the long runthe profit-maximising level of output for a monopolistically competitive firm occurs where price is greater than marginal cost and the firm is not at the minimum point of its average total cost curve. Unlike a perfectly competitive firm, a monopolistically competitive firm does not achieve allocative efficiency or productive efficiency.5.Define marketing and explain how firms use it to differentiate their products. Marketingrefers to all the activities necessary for a firm to sell a product to consumers. Firms use brand management and advertising to earn profits and defend profits from competitors.6.Identify the key factors that determine a firm’s profitability. The most important factorsunder a firm’s control are its ability to differentiate its product and to produce at a lower average cost than competing firms. Other factors that affect profitability are not under a firm’s control.These factors include the prices of the inputs it uses in production and random chance. Chapter ReviewChapter Opener: Starbucks: Growth through Product DifferentiationSince the first Starbucks coffee shop opened in 1971, the firm has grown into a worldwide company. But the growth has been in the number of shops, over 8,000, rather than the size of the shops themselves. Starbucks faces competition from other firms. Neighbourhoods often have three or more coffeehouses. Barriers to entry into the market for coffeehouses are low and firms differentiate their products by offering different menus and services.Demand and Marginal Revenue for a Firm in a Monopolistically Competitive MarketMonopolistic competition is a market structure in which barriers to entry are low, and many firms compete by selling similar, but not identical, products. Production differentiation allows monopolistically competitive firms to raise their prices without losing all their customers. (A price increase will, however, cause some customers to switch to another similar product.)The control monopolistically competitive firms have over their prices is limited because they face competition from firms selling similar products. Since firms face downward-sloping demand curves when marginal revenue is less than price.10155 ChapterHelpful Study HintRestaurants, convenience stores, bookstores and petrol stations are all examples ofmonopolistically competitive firms. Petrol stations display their prices so thatdifferences between stations can easily be compared. Many motorists are willing tobuy at a slightly higher per litre price if a station is in a more convenient location thana station that offers a lower price. Some consumers believe there are differencesbetween various brands of petrol. These customers are willing to pay a somewhathigher price for what they perceive as a superior product. The next time you drive orride in a car, notice how much difference there is between the prices charged by thestations you pass.How a Monopolistically Competitive Firm Maximises Profits in the Short RunAs with firms in other markets, a monopolistically competitive firm will maximise profits by producing the level of output that makes marginal revenue (MR) equal to marginal cost (MC). Because the MR curve lies below the firm’s demand curve, the firm will maximise profits where price (P) exceeds MC.Helpful Study HintThe table and graph in Figure 10.4 provide an example of a firm that makes a short-run profit. Notice that (a) the relevant values for MR, MC and ATC are determined atthe profit-maximising quantity, or where MR=MC, (b) when firms earn profits theATC curve crosses the demand curve at two points, and (c) at the profit maximisingoutput P > MR.What Happens to Profits in the Long Run?Short-run profits give entrepreneurs an incentive to enter a market and establish new firms. The demand curve of an established firm shifts to the left as new firms enter the market. Entry will continue until the firm’s demand curve is tangent to its ATC curve. In the long run, the firm’s price will equal average total cost, the firm breaks even and the firm’s demand curve becomes more elastic.Short-run losses will lead some firms to exit their market. As a result, the demand curve for a firm remaining in the market shifts to the right and becomes less elastic. The exit of firms continues until the representative firm can charge a price equal to the average total cost in the long run.Monopolistic competition: the competitive market in a more realistic setting 156Helpful Study HintThis section of the textbook contains several features to help you understand thetransition of the market from short-run to long-run equilibrium. Don’t Let ThisHappen to You! (pages 321-2) warns you not to confuse economic and accountingprofit. Graphs in Figure 10.5 (page 320) illustrate the short run for a firm earningprofits and how these profits are eliminated in the long run firm. Table 10.2 (page321) offers a comprehensive graphical summary of the short run and long run for amonopolistically competitive firm. Making the Connection 10.1 (page 322) andSolved Problem 10.2 (page 322) use the experience of Apple Computers to analysethe short run and long run under monopolistic competition. Making the Connection10.2 describes the efforts of a cosmetics company to stay ahead of its competition.Comparing Perfect Competition and Monopolistic CompetitionThere are two important differences between long-run equilibrium perfect competition and monopolistic competition. Monopolistically competitive firms charge a price greater than marginal cost and they do not produce at minimum average total cost. Since price exceeds marginal cost, allocative efficiency is not achieved, and since price is greater than minimum average total cost, productive efficiency is not achieved. Monopolistically competitive firms have excess capacity. Despite these characteristics, consumers benefit from purchasing products that are differentiated.Helpful Study HintAlthough monopolistic competition appears to fall short of perfect competition interms of economic efficiency, the textbook rightly notes that consumers are willing topay for the variety offered by monopolistically competitive firms. Consider usingpetrol stations once again as an example. Let’s say there are three petrol stations on asingle street corner. During most hours of the day at least one or two of the stationsare not busy; one can interpret this as excess capacity. But during rush hours all threestations have customers. Enough drivers are willing to pay to keep all three stationsoperating for the convenience of not waiting in long lines during peak hours.Supermarkets offer another example of consumers’ willingness to pay for greaterconvenience. Most supermarkets open additional check-out lines – some forconsumers with just a few items to buy – when long lines start to form.How Marketing Differentiates ProductsFirms can differentiate their products through marketing. Marketing refers to all the activities necessary for a firm to sell a product to a consumer. Firms use two marketing tools to differentiate their products. The first marketing tool is brand management. Brand management refers to the actions of a firm157 Chapter10intended to maintain the differentiation of a product over time. Economic profits are earned when a firm introduces a new product, but this leads to the entry of firms producing similar products and the profits are eliminated. Firms use brand management to put off the time when they will no longer be able to earn profits. The second marketing tool is advertising. Advertising shifts the demand curve for a product to the right and makes the demand curve more inelastic. Successful advertising allows the firm to sell more at every price. Advertising also increases costs. If the increase in revenue from advertising exceeds the costs, profits will rise.Once a firm has established a brand name it has an incentive to defend it. Firms can apply for a trademark. A trademark grants legal protection against other firms using a product’s name. Companies will spend substantial amounts of money to ensure that their brand names are entitled to legal protection. If firms do not prevent the unauthorised use of their trademarks, they may be no longer entitled to legal protection.What Makes a Firm Successful?A firm can control some of the factors that allow it to make economic profits. Other factors are uncontrollable. Controllable factors include the ability a firm has to differentiate its product and the ability a firm has to produce at a lower average total cost than competing firms. Uncontrollable factors include input prices, changes in consumer tastes and random chance.Solved ProblemChapter 10 in the textbook includes two Solved Problems to support learning objectives 2 (“Explain how a monopolistically competitive firm decides the quantity to produce and the price to charge”) and 3 (“Analyse the situation of a monopolistically competitive firm in the long run”). The following Solved Problem supports another of this chapter’s learning objectives.Solved Problem 12-3 Supports learning objective 5: Define marketing and explain how firms use it to differentiate their products.We Came. We Marketed. We Sold.3Com Corporation was incorporated in the U.S. in 1979 and specialises in providing computer network devices such as routers and network switches. Among 3Com’s clients are businesses that want to improve the communication and security capabilities of their computer systems. 3Com is not a household name in the manner of McDonald’s or Microsoft, but marketing is an important part of the company’s success. It faces stiff competition from other computer service providers, such as Cisco Systems, and uses advertising and trademarks to influence its customers. 3Com’s advertising efforts are aimed primarily at computer network managers; for example, an advertising agency developed a two-page ad for 3Com titled “We Came. We Saw. We Routed.” Ads such as these are placed in publications most likely to be seen by the target audience. It would be less effective for 3Com to place ads in People or Time magazines, since few of their readers are computer network managers, than it would be to advertise in business publications. The importance of establishing and maintaining 3Com’s trademarks is indicated by the guidelines the firm’s legal experts issue to employees. The following is a small sample of these guidelines for over 40 company and product trademarks:Always Use a Trademark as an Adjective, Followed by the Appropriate Description(s).If not, the trademark could become generic…make sure that 3Com and the ® symbol(3Com®) precedes a trademark mention of the product or service.Monopolistic competition: the competitive market in a more realistic setting 158 Correct: The 3Com® NBX® business telephone has powerful call processingfeatures. Incorrect: NBX® has powerful call-processing features.Sources: /corpinfo/en_US/legal/trademark/tmn_list.html/Portfolio/Advertising/advertising.html(a) Define marketing and explain the importance of marketing to firms.(b) Explain how 3Com Corporation uses marketing to differentiate its products.Solving the ProblemStep 1: Review the chapter material. Since this refers to the material in “How Marketing Differentiates Products,” you may want to review this section of the textbook which begins on page 327.Step 2: Define marketing and explain the importance of marketing to firms. Marketing refers to all the activities necessary for a firm to sell a product to a consumer. To earn profits, monopolistically competitive firms must differentiate their products. These firms use two marketing tools to do this: brand management and advertising.Step 3: Explain how 3Com Corporation uses marketing to differentiate its products. 3Com Corporation uses brand management, including extensive use of trademarks, and advertising to differentiate its products. 3Com Corporation focuses its marketing strategies on its customers; such as computer network managers.Self-Test(Answers are provided at the end of the Self-Test.)Multiple-Choice Questions1Why does a monopolistically competitive firm have a downward-sloping demand curve?a Because the firm is considered to be a monopoly in its own market.b Because changing the price will affect the quantity sold.c Because the firm is close to a price taker, like a wheat farmer.d Because the level of output produced depends on the cost structure of the firm.2In which case is the firm’s demand curve the same as marginal revenue?a In the monopolistically competitive case.b In the perfectly competitive case.c In both the monopolistically competitive case and the perfectly competitive case.d In neither the monopolistically competitive case nor the perfectly competitive case.3Which of the following measures is conceptually the same as price?a Marginal revenue.b Total revenue.c Average revenue.d None of the above.159 Chapter104When a monopolistically competitive firm cuts price, good and bad things happen.

One motive for advertising is to make the demand for a product more elasticso that when price is lowered there will be a greater increase in quantitydemanded.Answers to the Self-TestMultiple-Choice QuestionsQuestion Answer Explanation1 b Because changing the price affects the quantity sold, a monopolisticallycompetitive firm will face a downward-sloping demand curve, rather than the horizontal demand curve faced by a competitive firm, like a wheat farmer. 2 bA perfectly competitive firm faces a horizontal demand curve and does not have to cut the price in order to sell a larger quantity. A monopolistically competitive firm, however, must cut the price to sell more, so its marginal revenue curve will slope downward and will be below its demand curve. 3 cPrice is revenue per unit, or average revenue. Average revenue is equal to total revenue divided by quantity. Because total revenue equals price multiplied by quantity, dividing by quantity leaves just price. Therefore, average revenue is always equal to price. This will be true for firms in any of the four market structures. 4 bWhen the firm cuts the price by $0.50, one good thing and one bad thing happen: The good thing: It sells one more café latte; we can call this the output effect. The bad thing: It receives $.050 less for each café latte that it could have sold at the higher price; we can call this the price effect. 5 aAverage revenue equals price, which is $6.00 when six units are sold. Or, average revenue equals total revenue divided by output, or $18.00/6 = $3.00. 6 aArea A shows the loss of revenue from a price cut = $.50 x 5 = $2.50. 7 bEvery firm that has the ability to affect the price of the good or service it sells will have a marginal revenue curve that is below its demand curve. Only firms in perfectly competitive markets, which can sell as many units as they want at the market price, have marginal revenue curves that are the same as their demand curves. 8 cAll firms use the same approach to maximise profits: Produce where marginal revenue is equal to marginal cost. 9 bMarginal cost equals marginal revenue when 900 units of output are produced and sold. Consumers are willing to pay $15 for 900 units. 1 cIn both cases, the output level is set where marginal revenue equals marginal cost. 11 aCorrect. Profit = (P – ATC) Q, or alternatively, Profit = TR – TC, where TR = P x Q, and TC = ATC x Q. 12 b At this level of output, marginal revenue of $1.50 equals marginal cost.13 c As new coffeehouses open, the firm’s demand curve will shift to the left. Thedemand curve will shift because the existing firms will sell fewer cups of coffeeat each price now that there are additional coffee coffeehouses in the area selling similar drinks. The demand curve will also become more elastic becauseconsumers in the area now have additional coffeehouses from which to buycoffee, so existing firms will lose more customers if they raise their prices.14 b Since price is less than average total cost, the firm is suffering losses. Firm losses will lead to the exit of some firms in the industry.15 b In the long run, a monopolistically competitive firm earns zero economic profit, or P = ATC.16 c Firms try to avoid losing profits by reducing the cost of producing their products,by improving their products, or by convincing consumers their products areindeed different from what competitors offer. To stay one step ahead of itscompetitors, a firm has to offer consumers goods or services that they perceiveto have greater value than those offered by competing firms.17 a The monopolistically competitive firm has excess capacity equal to thedifference between its profit-maximising level of output and the productivelyefficient level of output.18 bConsumers face a trade-off when buying the product of a monopolisticallycompetitive firm: They are paying a price that is greater than marginal cost andthe product is not being produced at minimum average cost, but they benefit from being able to purchase a product that is differentiated and more closelysuited to their tastes.19 a The actions of a firm intended to maintain the differentiation of a product over time are called brand management.20 c The factors under a firm’s control—the ability to differentiate its product and theability to produce it at lower cost—combine with the factors beyond its controlto determine the firm’s profitability.Short Answer Responses1. The textbook describe several brand management methods Starbucks uses to differentiate itsproducts. “Competitors have found it difficult to duplicate Starbucks’ European espresso bar atmosphere…Most importantly, Starbucks has continued to be very responsive to its customers’ preferences…” In addition, company-owned coffeehouses (rather than franchise businesses) enable Starbucks to have greater control of the products sold and how they are marketed. Despite the success it has enjoyed, low entry barriers will eventually enable other firms to copy much of what Starbucks has done. Starbucks must continue to use brand management techniques to postpone the time when its economic profits are eliminated.2. Low entry barriers are common to both market structures. This ensures that firms earn zeroeconomic profits in the long run.。

They often despair of eventrying to attempt to build their industries unless it is done in an autarkic context,behind protectionist walls because they do not believe they can compete withmore productive industries abroad. Discuss this issue in the context of theRicardian model of comparative advantage.2.In 1975, wage levels in South Korea were roughly 5% of those in the UnitedStates. It is obvious that if the United States had allowed Korean goods to befreely imported into the United States at that time, this would have causeddevastation to the standard of living in the United States.,because no producer in this country could possibly compete with such low wages. Discuss this assertion in the context of the Ricardian model of comparative advantage.3.The evidence cited in the chapter using the examples of the East Asia NewIndustrializing Countries suggests that as international productivities converge,so do international wage levels. Why do you suppose this happened for the East Asian NICs? In light of your answer, what do you think is likely to happen tothe relative wages (relative to those in the United States) of China in the coming decade? Explain your reasoning.4.When we examine the 2 Good 2 Country version of the Ricardian model ofcomparative advantage, we note that comparative advantage is totallydetermined by physical productivity ratios. Changes in wage rates in eithercountry cannot affect these physically determined comparative advantages, andhence cannot affect, which product will be exported by which country. However, when more than 2 goods are added to the model (still with 2 countries), changesin wage rates in one or the other country can in fact determine which good orgoods each of the countries will export. How can you explain this anomaly?5.An examination of the Ricardian model of comparative advantage yields theclear result that trade is (potentially) beneficial for each of the two tradingpartners since it allows for an expanded consumption choice for each. However, for the world as a whole the expansion of production of one product mustinvolve a decrease in the availability of the other, so that it is not clear that tradeis better for the world as a whole as compared to an initial situation of non-trade(but efficient production in each country). Are there in fact gains from trade forthe world as a whole? Explain.Quantitative/Graphing Problems1.

Use a graph to demonstrate why a profit-maximizing monopolistically competitive firm must operate at excesscapacity. Explain why a perfectly competitive firm is not subject to the same constraint.ANS:Competitive firms do not face downward-sloping demand. The graph shows the firm choosing a level of production in which the intersection of marginal revenue and marginal cost occurs at an output level where average total cost is decreasing. This profit-maximizing output level is less than the efficient scale (minimum of average total cost), and therefore the firm is said to be operating with excess capacity.DIF: 2 REF: 16-2 NAT: Analytic LOC: Monopolistic competitionTOP: Excess capacity MSC: Analytical5. In a small college town, four microbreweries have opened in the last two years. Demonstrate the effect of newmarket entrants on demand for existing firms (microbreweries) that already served this market. Assume that the local community now places a moratorium on new liquor licenses for microbreweries. How will thismoratorium affect the long-run profitability of incumbent firms?ANS:The arrival of a new entrant should be graphically depicted by a leftward shift in the demand curves faced by all incumbent firms. If firms are able to make economic profits, these will be able to be maintained in the long run if new entrants are not allowed (which would essentially be a barrier to entry, meaning the market would no longer be characterized as monopolistically competitive).DIF: 2 REF: 16-2 NAT: Analytic LOC: Monopolistic competitionTOP: Long-run equilibrium MSC: Analytical1084 Chapter 16/Monopolistic Competition6.

Assume the role of a critic of advertising. Describe the characteristics of advertising that reduce theeffectiveness of markets and decrease the social welfare of society.ANS:Advertising manipulates people's tastes and is psychological rather than informational.

Professional organizations (for example, the American Medical Association and the American Bar Association)have been active advocates for regulation to restrict the right of professionals to advertise. Describe whateconomic incentives might exist for existing professionals to restrict advertising.ANS:If advertising increases information about prices and services, then providers of professional services will berequired to compete with each other on the basis of price and service.

In markets where the government imposes an excise tax on unit sales, it also has a tendency to dabble withrestrictions on advertising (for example, cigarettes and hard liquor). Do potential (or actual) restrictions onadvertising in these markets serve the interest of a government that is interested in maximizing its tax revenuefrom the sale of these products? Explain your answer.ANS:In the case of the examples given, demand is quite inelastic, so restrictions on advertising are not likely to have a large impact on total sales but may have an impact on the distribution of sales across brand names. As such,government revenue is largely unaffected if the tax is on unit sales.DIF: 3 REF: 16-3 NAT: Analytic LOC: Monopolistic competitionTOP: Advertising MSC: AnalyticalSec 00 - Monopolistic CompetitionMULTIPLE CHOICE1.
