Describe how government is involved in creating amonopoly. Why might the government create one? Give an example.ANS:The government can create a monopoly by giving a single firm the exclusive right to produce some good. Monopolies are created for many reasons. When an industry is characterized by high fixed costs, a single firm can usually supply the entire market at a lower cost than having multiple firms in the industry. Examples include most utility companies. The government also grants sole ownership of inventions through patent laws in order to help eliminate the market failure that is likely to otherwise occur in the markets for those goods. Patents encourage creativity and research and development.DIF: 2 REF: 15-1 NAT: Analytic LOC: MonopolyTOP: Patents | Regulation MSC: Applicative2. What is the defining characteristic of a natural monopoly? Give an example of a natural monopoly.ANS:The defining characteristic of a natural monopoly is when a firm can supply a good or service to an entire market at a lower cost than could two or more firms.

In the market for "home heating" consumers typically have several options (e.g., electricity, heating fuel,natural gas, propane, etc.), yet we often think of firms in this industry as behaving like monopolists. Discuss the context in which your electricity provider is a monopolist. Is this characterization universally applicable?Explain your answer.ANS:In this case, the firms are monopolists in the short run when consumers are unable to change their "home heating" systems. In the long run, consumers can change from electric appliances to natural gas appliances and thus lessen the monopoly power of utility providers. As long as consumers are able to substitute, in the long run the monopoly pricing power is reduced.DIF: 3 REF: 15-2 NAT: Analytic LOC: MonopolyTOP: Monopoly MSC: Analytical4. There has been much discussion of deregulating electricity and natural gas delivery companies in the UnitedStates. Discuss the likely effect of deregulation on prices in these two industries.ANS:If deregulation leads to increased competition, then production and prices should move toward the competitive equilibrium. If deregulation does not lead to increased competition, then the monopoly production and price outcome is likely. The success of deregulation movements hinges on their ability to use markets to promote competitive market outcomes. If the industry is characterized by economies of scale, deregulation may worsen rather than improve the market as costs and prices could rise if more than one firm supplies output to the market.

Explain how a profit-maximizing monopolist chooses its level of output and the price of its goods.ANS:A profit-maximizing monopolist produces the output levelwhere marginal revenue equals marginal cost and charges the corresponding price from the market demand curve. Note that a monopolist charges a price that exceeds marginal cost, unlike a competitive firm, for which price equals marginal cost.DIF: 2 REF: 15-2 NAT: Analytic LOC: MonopolyTOP: Profit maximization MSC: AnalyticalChapter 15/Monopoly 1007 6. Graphically depict the deadweight loss caused by a monopoly. How is this similar to the deadweight loss fromtaxation?ANS:A profit-maximizing monopolist will choose to produce Q0 units of output and sell at price P0. However, marginal cost is MC0. This is identical to the deadweight loss of taxation when the tax forces a wedge between market price and marginal cost.DIF: 2 REF: 15-3 NAT: Analytic LOC: MonopolyTOP: Deadweight loss MSC: Analytical7. What is the deadweight loss due to profit-maximizing monopoly pricing under the following conditions: The price charged for goods produced is $10. The intersection of the marginal revenue and marginal cost curves occurs where output is 100 units and marginal revenue is $5. The socially efficient level of production is 110 units. The demand curve is linear and downward sloping, and the marginal cost curve is constant.ANS:1/2*(110-100)*($10-$5) = $25DIF: 3 REF: 15-3 NAT: Analytic LOC: MonopolyTOP: Deadweight loss MSC: Applicative8. Assume that a monopolist decides to maximize revenue rather than profit. How does this operating objective change the size of the deadweight loss? If you are a "benevolent" manager of a monopoly firm and areinterested in reducing the deadweight loss of monopoly, should you maximize profits or maximize revenue?Explain your answer.ANS:A revenue maximizer operates where MR = 0. This solution moves the monopolist closer to the socially optimal competitive outcome and reduces deadweight loss. Revenue maximization is potentially a more "socially" optimal objective for monopoly markets than profit maximization.DIF: 3 REF: 15-3 NAT: Analytic LOC: MonopolyTOP: T otal revenue MSC: Analytical9. One example of price discrimination occurs in the publishing industry when a publisher initially releases anexpensive hardcover edition of a popular novel and later releases a cheaper paperback edition. Use thisexample to demonstrate the benefits and potential pitfalls of a price discrimination pricing strategy.ANS:The answer should address the three basic lessons of price discrimination. First, price discrimination is a rational strategy that can lead to higher monopoly profits. Second, price discrimination requires an ability to separate customers according to their willingness to pay. Third, price discrimination can raise economic welfare.DIF: 2 REF: 15-4 NAT: Analytic LOC: MonopolyTOP: Price discrimination MSC: Analytical。

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.

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.

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.

国际经济学考试题库(答案版)一、试述H-O模型的主要内容并予以评价。
1、基本内容:资本丰富的国家在资本密集型产品上相对供给能力较强,劳动丰富的国家则在劳动密集型产品上相对供给能力较强。
根据比较优势原则,一国出口密集使用其丰富要素的产品,进口密集使用其稀缺要素的产品。
要素的自然禀赋—要素供给—要素的相对富饶程度—要素相对价格—生产成本差异—商品价格差异—贸易的发生2、评价:贡献:a、从一国经济资源优势解释国际贸易发生的原因;b、从实际优势出发决定贸易模式;c、从贸易对经济的影响分析贸易的作用。
局限性:a、禀赋并非贸易发生的充分条件;b、对需求因素未予以充分考虑,影响了理论对实际情况的分析;c、过分强调静态结果,排除技术进步及实际存在的情况,影响了理论的适用性。
二、结合货币市场和外汇市场,以美元为本币,请画图美联储增加货币供给后,美元对欧元的汇率将如何变动。
外汇指的是以外国货币表示的,为各国普遍接受的,可用于国际间债权债务结算的各种支付手段。
货币政策是指政府或中央银行为影响经济活动所采取的措施,尤指控制货币供给以及调控利率的各项措施。
一国货币供给的增加会使该国货币在外汇市场上贬值。
美国的货币市场决定美元的利率,美元利率则影响维持利率平价的汇率。
所以当美联储增加货币供给后,会导致美元相对欧元的贬值。
但美元供给的变动对长期利率和实际产出没有影三、什么是恶性通货膨胀,可能导致恶性通货膨胀的原因以及应对措施。
恶性通货膨胀又称“超速通货膨胀”,是三位数以上的通货膨胀。
指流通货币量的增长速度大大超过货币流通速度的增长,货币购买力急剧下降,物价水平加速上升,整体物价水平以极高速度快速上涨的现象,使民众对货币价值失去信心。
由于货币的流通量增加快速,使货币变得没有价值时,人们会急于要以货币换取实物,人心惶惶的结果只会更加速通货膨胀的恶化,整体经济濒临崩溃边缘。
恶性通货膨胀是一种不能控制的通货膨胀,在物价很快地上涨的情况下,就使货币失去价值。

Part Ⅰ. Fill in the blank with suitable content.1.Seven themes recur throughout the study of international economics. These are the gains from trade , the pattern of trade , protectionism the balance of payments, exchange rate determination, international policy coordination, international capital market.2. Countries engage in international trade for two basic reasons : comparative advantage and economics of scale .3. A country has a comparative advantage in producing a good if the opportunity cost of producing that good in terms of other goods is lower in that country than it is in other countries.4. Labor is the only one factor of production. LC a 、LW a and *LC a 、*LW a are the unit laborrequirement in cheese and wine at Home and Foreign, respectively. If aLC/aLW<aLC*/aLW* ,Home has a comparative advantage in cheese. C p /W p is the relative price of cheese, when aLC/aLW< Pc/Pw<aLC*/aLW* Home and Foreign specialize in producing cheese and wine , respectively.5. Labor is the only one factor of production. LC a 、LW a and *LC a 、*LW a are the unit laborrequirement in cheese and wine at Home and Foreign, respectively. L and L*are Home’s andForeign’s labor force. If LC a /LW a <C p /W p <*LC a /*LW a , the world relative supply of cheese equals(L/aLC )/(L*/aLW*) . Home’s gains from indirectly producing wine can be shown as (1/aLC)(Pc/Pw)-1/aLW6. In specific factors model(Q M =Q M (K, L M ); Q F =Q F (T, L F ); L=L M +L F ), if Home produces and trades manufactured goods for food , the overall comparison of the five change rate of goods price andfactor price MP ˆ、F P ˆ、K r ˆ、T r ˆ、W ˆinside Home is T F M K r P W P r ∧∧∧∧∧〉〉〉〉 . That is, the real↑↑M .7. There are two main reasons why international trade has strong effects on the distribution ofincome. First, resources can ’t move immediately or costlessly form one industry to another Second Industries differ in the factors of production they demand.8. In the Heckscher-Ohlin model,Comparative advantage is influenced by the interaction betweenrelative abundance and relative intensity9.According to stolper-sammelson effect if the relative price of a good rises, the real income of the factor which intensively used in that good will rise, while the real income of the other factor will fall.10.According to 罗布津斯基效应 Rybczynski effect , at unchanged relative goods price, if the supply of a factor of production increases, the output of the good that are intensive in that factor will rise, while the output of the other good will fall.11.According to H-O 模型H-O proposition , owners of a country’s abundant factors gain from trade, but owners of a country’s scare factors lose.12.According to 要素价格均等化命题 Factor price equalization proposition , international trade produces a convergence (收敛) of relative goods prices. This convergence, in turns, causes the convergence of the relative factor prices. Trade leads to complete equalization of factor prices.(完整的要素价格均等化)13. Three assumptions (假设) crucial to the prediction of factor price equalization are in reality untrue. These assumptions are (1) 两个国家都生产两种产品 both countries produce both goods (2) 两国技术相同 technologies are the same (3) 存在贸易壁垒:天然壁垒和人为壁垒There are barriers to trade: natural barriers and artificial barriers .14.“U.S. exports were less capit al-intensive than U.S. imports” is known as 里昂惕夫悖论 Leontiefparadox .15.The Ricardian Model , the Specific Factor model and the H-O model may be viewed as special cases (特殊情况) of 标准贸易模型 standard trade models16.The standard trade model derives (派生 推导) a world relative supply curve (曲线) from production possibilities and a world relative demand curve from preferences .17.To export-biased growth, if the decline (下降) of the welfare caused by the deterioration (恶化) of the terms of trade swap over (交换) the rise of the welfare caused by growth, the growth is immiserizing growth (贫困化增长).18. Some economists argued that export-biased growth by poor nations would worsen their term of trade so much that they would be worse off than if they had not grown at all. This situation is known as immiserizing growth (贫困化增长) .19.Immiserizing growth demands strict conditions, these conditions are economic growth is strongly export-biased , the growing country is large enough to affect the world price , RS and RD must be very steep .20.According to “ 梅茨勒悖论Metzle paradox ”, t ariffs and export subsidies (补贴) might have perverse (有害的) effects on internal price.21.In the model of “Monopolistic (垄断) Competition and Trade”, firms of an individual nation face the trade-off between economies of scale and variety of products .22. Marshall argued that there were three main reasons why a cluster of firms (企业集群)may be more efficient than an individual firm in isolation: specialized supplies , labor market pooling , knowledge spillovers (知识溢出)23.The pattern of intraindustry (产业内) trade itself is unpredicted, history and accident determine the details of the trade pattern. 39. When there is external economies (外部经济), the pattern of international trade is determined by economics of scale interact with comparative advantage .24. The indexes (指标)of intrainindustry trade of a industry can be calculated by the standard formula:25. Interindustry trade and intrainindustry (产业内) trade are the sources of gains from trade . When countries are similar in their relative factor supplies 、scale economies and product differentiations are important , intrainindustry trade is the dominant source (主要来源) of gains from trade, everyone gains from trade.26.The argument of temporary (暂时的) protection of industries to enable them to gain experience is known as 幼稚产业论the infant industry argument27. If we add together the gains and losses from a tariff, We find the net effect on nationalwelfare can be separated into two parts: terms of trade gain and efficiency loss 28.Why do countries adopt trade policies such as tariff or import quota, which produce more costs than benefits?—— trade politics 29.In the political economy of trade policy (贸易政策的政治经济学) , government are assumed to (被假定为)maximize 政治成功political success rather than 国家福利 national welfare . 30.Deviations from free trade can sometimes increase national welfare. These arguments include the term of trade argument for a tariff and the domestic market failure argument31.According to “Specific rule (对症规则) ”, domestic market failure should be corrected by domestic policies aimed directly at the problem’s sources.32. Although market failures are probably common, the domestic market failure argument against free trade should not be applied too freely.First domestic market failure should be corrected by domestic policies aimed directly at the problems ’ sources ;Second economists cannot diagnose marketexp 1exp orts importsI orts imports -=-+failure well enough to prescribe policy.33. International trade often produces losers as well as winners. In the actual politics of trade policy, income distribution is of crucial importance. 集体行动问题The problem of collective action can explain why policies that not only seem to produce more costs than benefits but that also seem to hurt far more voters them they can help can nonetheless be adopted.34.The WTO includes four aspects content: GATT 1994,GATS,TRIPS , TRIMS35.“Nondiscriminatory” principles (非歧视性原则)include most favored nation principle and national treatment principle36.For preferential(优惠)trading agreements, such as customs union , countries must cede part of their sovereignty to supranational entity(必须放弃部分主权的超国家实体)37.Whether a customs union(关税同盟)is desirable(可取)or undesirable depends on whetherindustrialization and coping with the problems of the dual economy. Correspondingly, there are two main arguments for developing countries to pursue policy of import-substituting industrialization. The two arguments are the infant industry argument t and market failure justification for infant industry protection.40. Sophisticated proponents of the infant industry argument have identified two market failures as reasons why infant industry protection may be a good idea:The imperfect capital markets justification and The appropriability argument .PartⅡ. True or False (true and false are denoted by “T” and “F”, respectively)1. If a LW*/a L C*<a LW/a L C, Home’s relat ive productivity in cheese is higher. (T )2. According to the Ricardian model, it is precisely because the relative wage is between the relative productivities that each country ends up with a cost advantage in one good.The good for which *Li a/Li a>w/*w will be produced in Foreign. ( F )3. It is precisely because the relative wage is between the relative productivities that each country ends up with a cost advantage in one good. ( T )4.Long-run convergence(长期收敛) in productivity(生产力)produces long-run convergence inwages. ( T )5. “Korean workers earn only $2.50 an hour; if we allow Korea to export as much as it likes to the United States, our workers will be forced down to the same level. You can’t import a $5 shirt without importing the $2.50 wage that goes with it.” (F )6.The proposition that trade is beneficial is unqualified(不合格). That is, there is no requirement that a country be “competitive” or that the trade be “fair”. ( T)7. Free trade is beneficial only if your country is strong enough to stand up to foreign competition.( F )8. Foreign competition is unfair and hurts other countries when it is based on low wages. (F)9. Trade exploits a country and make it worse off if its workers receive much lower wage than workers in other nations. (F )10.The Ricardian Model predicts an extreme degree(预测一个极端的程度) of specialization(专业化). ( T )11.The Ricardian Model neglects(忽略) the effects on income distribution. (T )12. The basic prediction of the Ricardian model has been strongly confirmed by a number of studies over years. ( T )13. The Ricardian Model predicts that countries tend to export those goods in which their productivity is relative high. ( T )14. We can think of factor specificity as a matter of time. ( T )15.The opportunity cost of manufacture in terms of food is denoted by(表示) MPL M /MPL F. ( F )16.A equal proportional change in price have no real effects on the real wage, real income of capital owner and land owner. ( T )17. Trade benefits the factor that is specific to the import-competing sectors of each country but hurts the factor to the export sectors, with ambiguous effects on mobile factors. ( F )18.It is possible in principle for a country’s government to use taxes and subsidies(补贴) to redistribute(重新分配)income to give each individual more of both goods. ( T )19. Although international trade has strong effects on income distribution, there are still possible in principle to make each individual better off. ( T )20. Typically, those who gain from trade in any particular product are a much more concentrated, informed, and organized group than those who lose. ( F )21. Conflicts of interest(利益冲突) within nations are usually more important in determining trade policy than conflicts of interest between nations. ( T )22. Generally, economists do not regard the income distribution effects of trade as a good reason to limit trade. ( T )23.The formulation of trade policy(贸易政策的制定) is a kind of political process(政治进程). ( T )24. “The world’s poorest countries can’t find anything to export. There is no resource that i s abundant—certainly not capital or land, and in small poor nations not even labor is abundant.” ( F )25. Wage inequality in U.S. increased between the late 1970s and the early 1990s, economists attribute the change to the growing exports of manufactured goods from NIEs. ( T )26. If the factor-proportion theory was right, a country would always export factors for which the income share exceeded the factor share, import factors for which it was less. ( F )27.The H-O model can predict not only the direction but the volume of trade(贸易量). ( T )28.Factor trade in general turns out to be much smaller than the H-O model predicts. ( T )29. According to an influential recent paper, the H-O model can predict not only the direction but the volume of trade. Factor trade in general turn out to be t he same a s the H-O model predicts. ( F )30. Only by dropping the Heckscher-Ohlin assumption that technologies are the same across the countries can the overall pattern of international trade be well predicted by the H-O model.( T )31.If a country want to maximize its national welfare, the consumption point is where the highest isovalue line is tangent to the highest reachable indifference curve. ( T )32.A rise in the terms of trade increases a country’s welfare, while a decline in the terms of trade reduces its welfare. ( T )33.Export-biased growth tends to improve the growing country’s terms of trade at the rest of the world’s expense.( F )34.If the two countries allocate(分配) their change in spending in the same proportions, there will not be a terms of trade effect. ( T )35. If the country receiving a transfer spends a higher proportion of an increase income on its export good than the giver, a transfer raises world relative demand for the recipient’s export good and thus improve its terms of trade. ( T )36.A transfer worsens the donor’s terms of trade if the donor has a higher mariginal propensity to spend on its export good than the recipient(受体). ( T )37.A transfer improves the donor’s terms of trade, worsens recipient’s terms of tra de. ( F )38.A transfer of income——say foreign aid——could conceivably leave the recipient worse off. ( T )39.A tariff improves Home’s terms of trade and worsens Foreign’s, while a Home export subsidy worsens Home’s terms of trade and improve Foreign’s.( T )40. Where there is economies of scale, there is imperfectly competitive market structure. ( F )41.If intraindustry trade is the dominant source of gains from trade, everyone gains from trade. ( T )42.Effect on the distribution of income within countries often weight more heavily on policy than terms of trade concerns. ( T )43.The usual market structure in industries characterized by internal economies of scale is monopolistic competition. ( F )44.Today, antidumping(反倾销) may be a device of protectionism. ( T )45.Reciprocal(相互) dumping tends to increase the volume of trade in goods that are quite identical(一致). ( F )46.It is possible that reciprocal dumping increase national welfare. ( T )47.Strong external(外部) economies te nd to “locked in” the existing patterns of interindustry trade, even if the patterns are run counter to(背道而驰) comparative advantage. ( T )48.A trading country can conceivably lose from trade is potentially justify protectionism. ( T )49.Like static external economies, dynamic external economies can lock in an initial advantage in an industry. ( T )50.The stratigic trade policy is related to the model of “Monopolistic competition, differentiate product s and intraindustry trade”. ( F )51.The model “Oligopoly, homogeneous products and intraindustry trade” is first developed by Krugman and Helpman . ( F )52.Trade in factors is very much like trade in goods, it occurs for much the same reasons and produces similar results. ( T )53.Trade in factors is an alternative(替代) to trade in goods for the allocation of resources.

( T )58.Nominal(名义)tariff reflects the effective rate of protection(有效保护率). (F)59.The costs and benefits analysis of a tariff is correct if only the direct gains to producers and consumers in a given market accurately measure the social gains. ( T )60.The costs and benefits analysis of a tariff is correct if only a dollar’s worth of benefits to each group is the same. ( T )61.A VER is exactly like an import quota which the license are assigned to foreign government. ( T )62.VER S are much more costly than tariffs. ( T )63.Local content laws have been widely used by developing countries trying to shift their manufacturing from assembly back into intermediate goods. ( T )64. A political argument for free trade reflects the fact that a political commitment to free trade may be a good idea in practice even though there may be better policies in principle. ( T )65.Deviations from free trade can sometimes increase national welfare. (T )66.For a sufficiently small tariff the terms of trade gain of small country must outweigh theefficiency loss.( F )67.The domestic market failure argument against free trade is intellectually impeccable but of doubtful usefulness. (F )68. “U.S. farm exports don’t just mean hi gher incomes for farmers — they mean higher income for everyone who sell goods and services to the U.S. farm sector”. This remark is a potential validargument for export subsidy. ( T )69.Most deviations from free trade are adopted not because their benefit exceed their costs but because the public fails to understand their true costs. ( T )70.If there is marginal social costs rather than marginal social benefits, domestic market failure reinforce the case for free trade. ( T )71.The electoral competition model believes political competition will drive both parties to propose tariffs close to t M, the tariff preferred by the medium voter. ( T )72.The problem of collective action can best be overcome when a group is large and/or well organized. (F )73.Trade policy that produce more costs than benefits, hurt more consumers than producers can’t be adopted.( F )74.

The story of the prisoners' dilemma contains a general lesson that applies to any group trying to maintain cooperation among its members.ANS: T DIF: 1 REF: 17-2NAT: Analytic LOC: Oligopoly TOP: Prisoners' dilemmaMSC: Interpretive15. In the prisoners' dilemma game, one prisoner is always better off confessing, no matter what the other prisoner does.ANS: T DIF: 1 REF: 17-2NAT: Analytic LOC: Oligopoly TOP: Prisoners' dilemmaMSC: Interpretive16.

The game that oligopolists play in trying to reach the oligopoly outcome is similar to the game that the two prisoners play in the prisoners' dilemma.ANS: T DIF: 1 REF: 17-2NAT: Analytic LOC: Oligopoly TOP: Game theory MSC: Interpretive18. In the case of oligopolistic markets, self-interest makes cooperation difficult and it often leads to an undesirable outcome for the firms that are involved.ANS: T DIF: 1 REF: 17-2NAT: Analytic LOC: Oligopoly TOP: Game theory MSC: Interpretive19. When prisoners' dilemma games are repeated over and over, sometimes the threat of penalty causes both parties to cooperate.ANS: T DIF: 2 REF: 17-2NAT: Analytic LOC: Oligopoly TOP: Prisoners' dilemmaMSC: Interpretive20.

Even when allowed to collude, firms in an oligopoly may choose to cheat on their agreements with the rest ofthe cartel. Why?ANS:Individual profits can be increased at the expense of group profits if individuals cheat on the cartel's cooperative agreement. DIF: 2 REF: 17-1 NAT: AnalyticLOC: Oligopoly TOP: Cartels MSC: Interpretive2. What effect does the number of firms in an oligopoly have on the characteristics of the market?ANS:As the number of firms increases, the equilibrium quantity of goods provided increases and price falls; the market begins to resemble a competitive one.DIF: 2 REF: 17-1 NAT: AnalyticLOC: Oligopoly TOP: Oligopoly MSC: Analytical1156 Chapter 17/Oligopoly3.

Describe the source of tension between cooperation and self-interest in a market characterized by oligopoly.Use an example of an actual cartel arrangement to demonstrate why this tension creates instability in cartels. ANS:The source of the tension exists because total profits are maximized when oligopolists cooperate on price and quantity by operating as a monopolist. However, individual profits can be gained by individuals cheating on their cooperative agreement. This is why cooperative agreements among members of a cartel are inherently unstable. This is evident in the problem OPEC experiences in enforcing the cooperative agreement on production and price of crude oil.DIF: 2 REF: 17-1 NAT: AnalyticLOC: Oligopoly TOP: Cartels MSC: Interpretive5. Describe the output and price effects that influence the profit-maximizing decision faced by a firm in anoligopoly market. How does this differ from output and price effects in a monopoly market?ANS:Output effect: Price > Marginal cost => increased output will add to profitPrice effect: increased quantity is sold at a lower price => lower revenue (profit?)An oligopolist must take into account how the output and price effects will be influenced by competitors' production decisions, or it must assume competitors' production will not change in response to its own actions.DIF: 3 REF: 17-1 NAT: AnalyticLOC: Oligopoly TOP: Profit maximization | Oligopoly MSC: InterpretiveChapter 17/Oligopoly 11576. Explain how the output effect and the price effect influence the production decision of the individualoligopolist.ANS:Since the individual oligopolist faces a downward-sloping demand curve, she realizes that if she increases output, all output must be sold at a lower market price. As such, the revenue from selling the additional units at the lower market price must exceed the loss in revenue from selling all previous units at the new lower price. Otherwise, profits will fall as output (production) is increased.DIF: 2REF: 17-1 NAT: Analytic LOC: OligopolyTOP: Profit maximization | Oligopoly MSC: Interpretive 7.

Nike and Reebok (athletic shoe companies) are considering whether or not to advertise during the Super Bowl.Devise a simple prisoners' dilemma game to demonstrate the strategic considerations that are relevant to this decision. Does the repeated game scenario differ from a single period game? Is it possible that a repeated game (without collusive agreements) could lead to an outcome that is better than a single-period game? Explain the circumstances in which this may be true.ANS:The answer should show that if both shoe companies decide to advertise they will both be worse off than if they did not. It should also show that each company has the individual incentive to advertise. The dominant strategy of both companies will be to advertise, regardless of what the other is doing. If the game is repeated more than once it is possible that the shoe companies will decide not to advertise in the hopes that the other company adequately understands the mutually beneficial gains that come from not advertising.DIF: 3REF: 17-2 NAT: Analytic LOC: Oligopoly TOP: Prisoners' dilemma MSC: Applicative9. Outline the purpose of antitrust laws. What do they accomplish?ANS:The purpose of antitrust laws is to move markets toward a competitive equilibrium outcome.

Explain the practice of resale price maintenance and discuss why it is controversial.ANS:Resale price maintenance is a requirement by producers that retailers sell their product for a price specified by the manufacturer. It is controversial because on the surface it appears to limit the ability of retailers to compete on the basis of price. However, if the manufacturer does not exercise resale price maintenance a free-rider problem may become evident among the retailers and ultimately lead to lower profits for the manufacturer.DIF: 2 REF: 17-3NAT: Analytic LOC: The role of government TOP:Resale price maintenanceMSC: Interpretive1158 Chapter 17/Oligopoly11. Explain the practice of tying and discuss why it is controversial.ANS:Tying is the practice of bundling goods for sale. It is controversial because it is perceived as a tool for expanding the market power of firms by forcing consumers to purchase additional products. However, economists are skeptical that a buyer's willingness to pay increases just because two products are bundled together. In other words, simply bundling two products together doesn't necessarily add any value.

Describe how government is involved in creating a monopoly. Why might the government create one? Give anexample.ANS:The government can create a monopoly by giving a single firm the exclusive right to produce some good. Monopolies are created for many reasons. When an industry is characterized by high fixed costs, a single firm can usually supply the entire market at a lower cost than having multiple firms in the industry. Examples include most utility companies. The government also grants sole ownership of inventions through patent laws in order to help eliminate the market failure that is likely to otherwise occur in the markets for those goods. Patents encourage creativity and research and development.DIF: 2 REF: 15-1 NAT: Analytic LOC: MonopolyTOP: Patents | Regulation MSC: Applicative2. What is the defining characteristic of a natural monopoly?

In the market for "home heating" consumers typically have several options (e.g., electricity, heating fuel,natural gas, propane, etc.), yet we often think of firms in this industry as behaving like monopolists. Discuss the context in which your electricity provider is a monopolist. Is this characterization universally applicable?Explain your answer.ANS:In this case, the firms are monopolists in the short run when consumers are unable to change their "home heating" systems. In the long run, consumers can change from electric appliances to natural gas appliances and thus lessen the monopoly power of utility providers. As long as consumers are able to substitute, in the long run the monopoly pricing power is reduced.DIF: 3 REF: 15-2 NAT: Analytic LOC: MonopolyTOP: Monopoly MSC: Analytical4. There has been much discussion of deregulating electricity and natural gas delivery companies in the UnitedStates. Discuss the likely effect of deregulation on prices in these two industries.ANS:If deregulation leads to increased competition, then production and prices should move toward the competitive equilibrium. If deregulation does not lead to increased competition, then the monopoly production and price outcome is likely. The success of deregulation movements hinges on their ability to use markets to promote competitive market outcomes. If the industry is characterized by economies of scale, deregulation may worsen rather than improve the market as costs and prices could rise if more than one firm supplies output to the market.

Explain how a profit-maximizing monopolist chooses its level of output and the price of its goods.ANS:A profit-maximizing monopolist produces the output level where marginal revenue equals marginal cost and charges the corresponding price from the market demand curve.

Graphically depict the deadweight loss caused by a monopoly. How is this similar to the deadweight loss fromtaxation?ANS:A profit-maximizing monopolist will choose to produce Q0 units of output and sell at price P0. However, marginal cost is MC0.

What is the deadweight loss due to profit-maximizing monopoly pricing under the following conditions: Theprice charged for goods produced is $10. The intersection of the marginal revenue and marginal cost curves occurs where output is 100 units and marginal revenue is $5. The socially efficient level of production is 110 units. The demand curve is linear and downward sloping, and the marginal cost curve is constant.ANS:1/2*(110-100)*($10-$5) = $25DIF: 3 REF: 15-3 NAT: Analytic LOC: MonopolyTOP: Deadweight loss MSC: Applicative8. Assume that a monopolist decides to maximize revenue rather than profit. How does this operating objectivechange the size of the deadweight loss? If you are a "benevolent" manager of a monopoly firm and areinterested in reducing the deadweight loss of monopoly, should you maximize profits or maximize revenue?Explain your answer.ANS:A revenue maximizer operates where MR = 0. This solution moves the monopolist closer to the socially optimal competitive outcome and reduces deadweight loss. Revenue maximization is potentially a more "socially" optimal objective for monopoly markets than profit maximization.DIF: 3 REF: 15-3 NAT: Analytic LOC: MonopolyTOP: Total revenue MSC: Analytical9. One example of price discrimination occurs in the publishing industry when a publisher initially releases anexpensive hardcover edition of a popular novel and later releases a cheaper paperback edition. Use thisexample to demonstrate the benefits and potential pitfalls of a price discrimination pricing strategy.ANS:The answer should address the three basic lessons of price discrimination. First, price discrimination is a rational strategy that can lead to higher monopoly profits. Second, price discrimination requires an ability to separate customers according to their willingness to pay. Third, price discrimination can raise economic welfare.DIF: 2 REF: 15-4 NAT: Analytic LOC: MonopolyTOP: Price discrimination MSC: Analytical1008 Chapter 15/Monopoly10. What are the four ways that government policymakers can respond to the problem of monopoly?ANS:First, the government can try to make monopolized industries more competitive by using the power of antitrust laws.

In many countries, the government chooses to "internalize" the monopoly by owning monopoly providers ofgoods and services. (In some cases these firms are "nationalized," and the government actually buys orconfiscates firms that operate in monopoly markets). What would be the advantages and disadvantages of such an approach to ensure that the "best interest of society" is promoted in these markets? Explain your answer. ANS:As long as the government "owner" pursues a production and pricing policy that approaches a competitive outcome, social well-being can be enhanced. In this case the government ownership would benefit society. However, in most cases, government owners operate much like private sector monopolists. The political economy of government institutions does not ensure that government owners will pursue socially optimal policy. Also, governments have no incentive to reduce costs or innovate.DIF: 3 REF: 15-5 NAT: Analytic LOC: MonopolyTOP: Government MSC: Analytical13. Why might economists prefer private ownership of monopolies over public ownership of monopolies?ANS:The private monopolist is governed by the market. Even though the market solution is sub-optimal, it may be better than outcomes generated by publicly owned monopolies. Publicly owned monopolies may restrict output to levels below the private market outcome and thus generate an even lower level of social surplus than a privateprofit-maximizing monopolist.Private owners have an incentive to minimize cost as long as they reap benefits in the form of higher profits. Government bureaucrats have no incentive to reduce costs. The losers are customers and taxpayers, whose only recourse is the political system.DIF: 2 REF: 15-5 NAT: Analytic LOC: MonopolyTOP: Monopoly MSC: Analytical14. One solution to the problems of marginal-cost pricing of a regulated natural monopolist is average cost pricing.In this model, the monopolist is allowed to price its production at average total cost. How does average-cost pricing differ from marginal-cost pricing? Does this solution maximize social well-being?ANS:Under average-cost pricing, the monopolist earns zero economic profits, but average-cost pricing does not ensure a socially optimal market solution. Under marginal-marginal cost pricing, the monopolist cannot cover its total costs, so it will earn negative economic profits.
