1Answers to Textbook Problems1.At an exchange rate of$1.50per euro,the price ofa bratwurst in terms ofhot dogs is1.875(7.5/4)hot dogs per bratwurst.After a dollar appreciation to$1.25per euro,the relative price ofa bratwurst falls to1.56(6.25/4)hot dogs per bratwurst.Hot dogs have become more expensive relative to bratwurst.2.The Norwegian krone/Swiss franc cross rate must be6Norwegian krone per Swiss franc.58Krugman/Obstfeld•InternationalEconomics:Theory andPolicy,Eighth Edition3.When the yen depreciates vs.the dollar,its costs go up.This depresses its profits.On the other hand,ifit exports products to the U.S.,it can increase the yen price(without changing the dollar price)so there may be some offsetting effects.But,by and large,a firm that has substantial imported input costs does not relish a depreciating home currency.4.The dollar rates ofreturn are as follows:a.($250,000$200,000)/$200,000=0.25.b.($275$225)/$225=0.22.c.There are two parts to this return.One is the loss involved due to the appreciation ofthe dollar;the dollar appreciation is($1.38$1.50)/$1.50=0.08.The other part ofthe return is theinterestpaidbythe Londonbank onthe deposit,10percent.(The size ofthe deposit is immaterialto the calculation ofthe rate ofreturn.)In terms ofdollars,the realized return on the Londondeposit is thus2percent per year.5.Note here that the ordering ofthe returns ofthe three assets is the same whether we calculate real ornominal returns.a.The real return on the house would be25%10%=15%.This return could also be calculatedby first finding the portion ofthe$50,000nominal increase in the house’s price due to inflation($20,000),then finding the portion ofthe nominal increase due to real appreciation($30,000),and finally finding the appropriate real rate ofreturn($30,000/$200,000=0.15).b.Again,subtracting the inflation rate from the nominal return,we get20%10%=10%.c. 2% 10% = 8%.6.The current equilibrium exchange rate must equal its expected future level since,with equality ofnominal interest rates,there can be no expected increase or decrease in the dollar/pound exchange rate in equilibrium.Ifthe expected exchange rate remains at$1.52per pound and the pound interest rate rises to10percent,then interest parity is satisfied only ifthe current exchange rate changes such that there is an expected appreciation ofthe dollar equal to5percent.This will occur when theexchange rate rises to$1.60per pound(a depreciation ofthe dollar against the pound).7.Ifmarket traders learn that the dollar interest rate will soon fall,they also revise upward theirexpectation ofthe dollar’s future depreciation in the foreign-exchange market.Given the current exchange rate and interest rates,there is thus a rise in the expected dollar return on euro deposits.The downward-sloping curve in the diagram below shifts to the right and there is an immediatedollar depreciation,as shown in the figure below where a shift in the interest-parity curve from IIto II leads to a depreciation ofthe dollar from E0to E1.Figure13.2Chapter 13 Exchange Rates and the Foreign-Exchange Market: An Asset Approach 598. The analysis will be parallel to that in the text. As shown in the accompanying diagrams, a movementdown the vertical axis in the new graph, however, is interpreted as a euro appreciation and dollar depreciation rather than the reverse. Also, the horizontal axis now measures the euro interest rate. Figure 13.3 demonstrates that, given the expected future exchange rate, a rise in the euro interest rate from R 0 to R 1 will lead to a euro appreciation from E 0 to E 1.Figure 13.4 shows that, given the euro interest rate of i, the expectation ofa stronger euro in the future leads to a leftward shift ofthe downward-sloping curve from IItoIpIp and a euro appreciation (dollar depreciation) from E to Ep. A rise in the dollar interest rate causes the same curve to shift rightward, so the euro depreciates against the dollar. This simply reverses the movement inFigure 13.4, with a shift from IpIp to II, and a depreciation ofthe euro from Ep to E. All oftheseresults are the same as in the text when using the diagram for the dollar rather than the euro.Figure 13.3Figure 13.49. a. Ifthe Federal Reserve pushed interest rates down, with an unchanged expected future exchangerate, the dollar would depreciate (note that the article uses the term “downward pressure” to meanpressure for the dollar to depreciate). In terms ofthe analysis developed in this chapter, a moveby the Federal Reserve to lower interest rates would be reflected in a movement from R to Rp inFigure 13.5, and a depreciation ofthe exchange rate from E to E *.Ifthere is a “soft landing,” and the Federal Reserve does not lower interest rates, then this dollardepreciation will not occur. Even ifthe Federal Reserve does lower interest rates a little, say fromR to R , this may be a smaller decrease then what people initially believed would occur. In thiscase, the expected future value ofthe exchange rate will be more appreciated than before,causing the interest-parity curve to shift in from IItoIpIp (as shown in Figure 13.6). The shift inthe curve reflectsthe “optimism sparkedbythe expectation ofa soft landing” andthis change inexpectations means that, with a fall in interest rates from R to R , the exchange rate depreciatesfrom E to E , rather than from E to E *, which would occur in the absence ofa change inexpectations.Figure 13.5Figure 13.660Krugman/Obstfeld•InternationalEconomics:Theory andPolicy,Eighth Editionb.The“disruptive”effects ofa recession make dollar holdings more risky.Risky assets must offersome extra compensation such that people willingly hold them as opposed to other,less riskyassets.This extra compensation may be in the form ofa bigger expected appreciation ofthecurrency in which the asset is held.Given the expected future value ofthe exchange rate,a bigger expected appreciation is obtained by a more depreciated exchange rate today.Thus,a recessionthat is disruptive and makes dollar assets more risky will cause a depreciation ofthe dollar.10.The euroislessrisky foryou.Whentherestofyourwealth falls,the eurotendstoappreciate,hri s by giving you a relatively high payoffin terms ofdollars.Losses on your euro assets, on the other hand,tend to occur when they are least painful,that is,when the rest ofyour wealth is unexpectedly high.Holding the euro therefore reduces the variability ofyour total wealth.11.The chapter states that most foreign-exchange transactions between banks(which accounts for thevastmajorityofforeign-exchangetransactions)involve exchangesofforeigncurrencies forU.S.l r,hen the ultimate transaction involves the sale ofone nondollar currency for another nondollar currency.This central role ofthe dollar makes it a vehicle currency in international transactions.The reason the dollar serves as a vehicle currency is that it is the most liquid ofcurrencies since it is easy to find people willing to trade foreign currencies for dollars.The greater liquidity ofthe dollar ascompared to,say,the Mexican peso,means that people are more willing to hold the dollar than the peso,and thus,dollar deposits can offer a lower interest rate,for any expected rate ofdepreciation against athird currency,thanpeso deposits forthe samerate ofdepreciation againstthatthird currency.As the world capital market becomes increasingly integrated,the liquidity advantages ofholdingdollar deposits as opposed to euro deposits will probably diminish.The euro represents an economy as large as the United States,so it is possible that it will assume some ofthat vehicle role ofthe dollar, reducing the liquidity advantages to as far as zero.When it was first introduced in1999,the euro had no history as a currency,though,so some investors may have been leery ofholding it until itestablished a track record.As the euro has become more established,though,the liquidity advantage ofthe dollar should be fading(albeit slowly).12.Greater fluctuations in the dollar interest rate lead directly to greater fluctuations in the exchange rateusing the model described here.The movements in the interest rate can be investigated by shifting the vertical interest rate curve.As shown in Figure13.7,these movements lead directly to movements in the exchangerate.For example,an increase inthe interestrate from i to ip leads to a dollar appreciation from E to Ep.A decrease in the interest rate from i to i leads to a dollar depreciation from E to E.This diagram demonstrates the direct link between interest rate volatility and exchange rate volatility, given that the expected future exchange rate does not change.Figure13.7Chapter 13 Exchange Rates and the Foreign-Exchange Market: An Asset Approach 61 13.A tax on interest earnings and capital gains leaves the interest parity condition the same,since all itscomponents are multiplied by one less the tax rate to obtain after-tax returns.Ifcapital gains areuntaxed,the expected depreciation term in the interest parity condition must be divided by1less the tax rate. The component ofthe foreign return due to capital gains is now valued more highly than interest payments because it is untaxed.14. The forward premium can be calculated as described in the appendix. In this case, we find theforward premium on euro to be (1.26 一 1.20)/1.20 = 0.05. The interest rate difference between one-year dollar deposits and one-year euro deposits will be5percent because the interest difference must equal the forward premium on euro against dollars when covered interest parity holds.15. The value should have gone down as there is no more need to engage in intra EU foreign currencytrading.This represents the predicted transaction cost savings stemming from the euro.At thesame time, the importance ofthe euro as an international currency may have generated more trading in euros as more investors(from central banks to individual investors)choose to hold their fundsin euros or denominate transactions in euros. On net, though, we would expect the value offoreign exchange trading in euros to be less than the sum ofthe previous currencies.16.Ifthe dollar depreciated,all else equal,we would expect outsourcing to diminish.If,as the problemstates,much ofthe outsourcing is an attempt to move production to locations that are relativelycheaper,then the U.S. becomes relatively cheap when the dollar depreciates. While it may not be as cheap a destination as some other locations,at the margin,labor costs in the U.S.will have becomerelatively cheaper, making some firms choose to retain production at home. For example, we could say that the labor costs ofproducing a computer in Malaysia is220$and the extra transport cost is50$,but the U.S.costs were300$,then we would expect the firm to outsource.On the other hand,if the dollar depreciated 20% against the Malaysian ringitt, the labor costs in Malaysia would now be 264$(that is,20%higher in dollar terms,but unchanged in local currency).This,plus the transportcosts makes production in Malaysia more expensive than in the U.S., making outsourcing a less attractive option.。

曼昆经济学原理英文版文案加习题答案10章EXTERNALITIESWHAT’S NEW IN THE S EVENTH EDITION:There is a new In the News feature on ―What Should We Do about Climate Change.‖LEARNING OBJECTIVES:By the end of this chapter, students should understand:what an externality is.why externalities can make market outcomes inefficient.the various government policies aimed at solving the problem of externalities.how people can sometimes solve the problem of externalities on their own.why private solutions to externalities sometimes do not work.CONTEXT AND PURPOSE:Chapter 10 is the first chapter in the microeconomic section of the text. It is the first chapter in a three-chapter sequence on the economics of the public sector. Chapter 10 addresses externalities—the uncompensated impact of one person’s actions on the well-being of a bystander. Chapter 11 will address public goods and common resources (goods that will be defined in Chapter 11) and Chapter 12 will address the tax system.In Chapter 10, different sources of externalities and a varietyof potential cures for externalities are addressed. Markets maximize total surplus to buyers and sellers in a market. However, if a market generates an externality (a cost or benefit to someone external to the market) the market equilibrium may not maximize the total benefit to society. Thus, in Chapter 10 we will see that while markets are usually a good way to organize economic activity, governments can sometimes improve market outcomes.182Chapter 10/Externalities ? 183KEY POINTS:When a transaction between a buyer and seller directly affects a third party, the effect is called an externality. If an activity yields negative externalities, such as pollution, the socially optimal quantity in a market is less than the equilibrium quantity. If an activity yields positive externalities, such as technology spillovers, the socially optimal quantity is greater than the equilibrium quantity.Governments pursue various policies to remedy the inefficiencies caused by externalities. Sometimes the government prevents socially inefficient activity by regulating behavior. Other times it internalizes an externality using corrective taxes. Another public policy is to issue permits. For example, the government could protect the environment by issuing a limited number of pollution permits. The result of this policy is largely the same as imposing corrective taxes on polluters.Those affected by externalities can sometimes solve the problem privately. For instance, when one business imposes anexternality on another business, the two businesses can internalize theexternality by merging. Alternatively, the interested parties can solve the problem by negotiating a contract. According to the Coase theorem, if people can bargain without cost, then they can always reach an agreement in which resources are allocated efficiently. In many cases, however, reaching a bargain among the many interested parties is difficult, so the Coase theorem does not apply.CHAPTER OUTLINE:I. Definition of externality : the uncompensated impact of one person’s actions on the well -being of a bystander.A. If the impact on the bystander is adverse, we say that there is a negative externality.B. If the impact on the bystander is beneficial, we say that there is a positive externality.C. In either situation, decisionmakers fail to take account of the external effects of their behavior.II. Externalities and Market InefficiencyA. Welfare Economics: A Recap1. The demand curve for a good reflects the value of that good to consumers, measured by theprice that the marginal buyer is willing to pay.2. The supply curve for a good reflects the cost of producing that good.3. In a free market, the price of a good brings supply and demand into balance in a way thatmaximizes total surplus (the difference between theconsumers’ valuation of the good and the sellers’ cost of producing it).184 ? Chapter 10/ExternalitiesB. Negative Externalities1. Example: An aluminum firm emits pollution during production.2. Social cost is equal to the private cost to the firm of producing the aluminum plus theexternal costs to those bystanders affected by the pollution. Thus, social cost exceeds the private cost paid by producers.3. The optimal amount of aluminum in the market will occur where total surplus is maximized.a. Total surplus is equal to the value of aluminum to consumers minus the cost (social cost)of producing it.b. This will occur where the social-cost curve intersects with demand curve. At this point,producing one more unit would lower total surplus because the value to consumers is less than the cost to produce it.4. Because the supply curve does not reflect the true cost of producing aluminum, the marketwill produce more aluminum than is optimal. 5. This negative externality could be internalized by a tax on producers for each unit ofaluminum sold.ALTERNATIVE CLASSROOM EXAMPLE:A coal-fired power plant emits pollution during production.Chapter 10/Externalities ? 1856. Definition of internalizing an externality: altering incentives so that people takeaccount of the external effects of their actions.7. In the News: The Externalities of Country Livinga. In The Lorax by Dr. Seuss, urbanization is criticized while country living is consideredmore environmentally friendly.b. This article from The New York Times describes research that suggests that city livingmay in fact be ―green er‖ because of the use of public transportation.C. Positive Externalities1. Example: education.2. Education yields positive externalities because better-educated voters lead to a bettergovernment. Crime rates also drop as the education level of the population rises.3. In this case, the demand curve does not reflect the social value of a good.4. If there is a positive externality, the social value of the good is greater than the private value,and the optimum quantity will be greater than the quantity produced in the market.5. To internalize a positive externality, the government could use a subsidy.Figure 3ALTERNATIVE CLASSROOM EXAMPLE:The purchase of a fire extinguisher when an individual lives in an apartment complex This is a good time to discuss why the government taxes goods like alcohol, tobacco, and gasoline. You will find that students have heard the phrase ―sin tax,‖ but they often do not understand why economists might support such taxes (given thedeadweight loss from taxes discussed in Chapter 8).186 ?Chapter 10/Externalities6. Case Study: Technology Spillovers, Industrial Policy, and Patent Protectiona. A technology spillover occurs when one firm’s research and production efforts impactanother firm’s access to technological advance.b. It is difficult to measure the amounts of technology spillover that occur and this leads toa debate over whether or not the government should pursue policies to encourage theproduction of technology.c. Patent protection is a type of technology policy of the government because it protectsthe rights of inventors who create new technologies. Without patents, there would beless incentive to develop new ideas and technologies.III. Public Policies toward ExternalitiesA. When an externality causes a market to reach an inefficient allocation of resources, thegovernment can respond in two ways.1. Command-and-control policies regulate behavior directly.2. Market-based policies provide incentives so that private decisionmakers will choose to solvethe problem on their own.B. Command-and-Control Policies: Regulation1. Externalities can be corrected by requiring or forbidding certain behaviors.2. In the United States, the Environmental Protection Agency (EPA) develops and enforcesregulations aimed at protecting the environment.3. EPA regulations include maximum levels of pollution allowed or required adoption of aparticular technology to reduce emissions.C. Market-Based Policy 1: Corrective Taxes and Subsidies1. Externalities can be internalized through the use of taxes and subsidies.2. Definition of corrective tax: a tax designed to induce private decisionmakers to takeaccount of the social costs that arise from a negative externality.a. These taxes are preferred by economists over regulation, because firms that can reducepollution with the least cost are likely to do so (to avoid the tax) while firms thatencounter high costs when reducing pollution will simply pay the tax.b. Thus, this tax allows firms that face the highest cost of reducing pollution to continue topollute while encouraging less pollution over all.Chapter 10/Externalities ?187c. Unlike other taxes, corrective taxes do not cause a reduction in total surplus. In fact,they increase economic well-being by forcing decisionmakers to take into account thecost of all of the resources being used when making decisions.3. Case Study: Why Is Gasoline Taxed So Heavily?a. In the United States, almost half of what drivers pay for gasoline goes to gas taxes.b. This is to correct for three negative externalities associated with driving: congestion,accidents, and pollution.D. Market-Based Policy 2: Tradable Pollution Permits1. Example: EPA regulations restrict the amount of pollution that two firms can emit at 300 tonsof glop per year. Firm A wants to increase its amount of pollution. Firm B agrees to decrease its pollution by the same amount if Firm A pays it $5 million.2. Social welfare is increased if the EPA allows this situation. Total pollution remains the sameso there are no external effects. If both firms are doing this willingly, it must make thembetter off.3. If the EPA issued permits to pollute and then allowed firms to sell them, this would alsoincrease social welfare. Firms that could control pollution most inexpensively would do so and sell their permits, while those who encounter high costs when reducing pollution would buyadditional permits.4. Tradable pollution permits and corrective taxes are similar in effect. In both cases, firms mustpay for the right to pollute.a. In the case of the tax, the government basically sets the price of pollution and firms thenchoose the level of pollution (given the tax) that maximizes their profit.b. If tradable pollution permits are used, the government chooses the level of pollution (intotal, for all firms) and firms then decide what they are willing to pay for these permits.188 ?Chapter 10/ExternalitiesE. Objections to the Economic Analysis of Pollution1. Some individuals dislike the idea of allowing companies to purchase the right to pollute.2. Economists point out that ―people face trade-offs‖ (Principle #1) and we must decide howmuch we would be willing to give up in exchange for no pollution. It would likely not beenough.3. A clean environment can be viewed as any other good that obeys the law of demand. Thelower the price of environmental protection, the more the public will want.F. In the News: What Should We Do about Climate Change?1. Many policy analysts believe that taxing carbon is the best approach to dealing with globalclimate change..2. This article from The New York Times explains how the revenue-neutral carbon tax works inBritish Columbia and argues for its implementation in the United States..IV. Private Solutions to ExternalitiesA. We do not necessarily need government involvement to correct externalities.B. The Types of Private Solutions1. Problems of externalities can sometimes be solved by moral codes and social sanctions.a. Do not litter.b. The Golden Rule2. Many charities have been established that deal with externalities. The governmentencourages this private solution by allowing a deduction for charitable contributions in thedetermination of taxable income.a. Sierra Club (environment)b. University Alumni Association (scholarships)3. The parties involved in this externality (either the seller and the bystander or the consumerand the bystander) can possibly enter into an agreement to correct the externality.C. The Coase Theorem1. Definition of Coase theorem: the proposition that if private parties can bargainwithout cost over the allocation of resources, they can solve the problem ofexternalities on their own.Chapter 10/Externalities ?1892. Example: Dick owns a dog Spot who disturbs a neighbor (Jane) with its barking.a. One possible solution to this problem would be for Jane to pay Dick to get rid of the dog.The amount that she would be willing to pay would be equal to her valuation of the costsof the barking. Dick would only agree to this if Jane paid him an amount greater than thevalue he places on owning Spot.b. Even if Jane could legally force Dick to get rid of Spot, another solution could occur. Dickcould pay Jane to let him keep the dog.3. Whatever the initial distribution of rights, the parties involved in an externality can potentiallysolve the problem themselves and reach an efficient outcome where both parties are betteroff.D. Why Private Solutions Do Not Always Work1. Definition of transaction costs: the costs that parties incur in the process ofagreeing and following through on a bargain.2. Coordination of all of the interested parties may be difficult so that bargaining breaks down.This is especially true when the number of interested parties is large. SOLUTIONS TO TEXT PROBLEMS:Quick Quizzes1. Examples of negative externalities include pollution, barking dogs, and consumption ofalcoholic beverages. Examples of positive externalitiesinclude the restoration of historicbuildings, research into new technologies, and education. (Many other examples of negativeand positive externalities are possible.) Market outcomes are inefficient in the presence ofexternalities because markets produce a larger quantity than is socially desirable when thereis a negative externality and a smaller quantity than is socially desirable when there is apositive externality. The market outcomes do not account for all of the costs (negativeexternalities) or benefits (positive externalities) to society.2. The town government might respond to the externality from the smoke in three ways: (1)regulation; (2) corrective taxes; or (3) tradable pollution permits.Regulation prohibiting pollution beyond some level is good because it is often effective atreducing pollution. But doing so successfully requires the government to have a lot ofinformation about the industries and the alternative technologies that those industries couldadopt.Corrective taxes are a useful way to reduce pollution because the tax can be increased to getpollution to a lower level and because the taxes raise revenue for the government. The tax ismore efficient than regulation because it gives factories economic incentives to reducepollution and to adopt new technologies that pollute less.The disadvantage of correctivetaxes is that the government needs to know a lot of information to pick the right tax rate.Tradable pollution permits are similar to corrective taxes but allow the firms to trade the rightto pollute with each other. As a result, the government does not need as much informationabout the firms’ technologies. The government c an simply set a limit on the total amo unt of190 ?Chapter 10/Externalitiespollution, issue permits for that amount, and allow the firms to trade the permits. Thisreduces pollution while allowing economic efficiency.3. Examples of private solutions to externalities include moral codes and social sanctions,charities, and relying on the interested parties entering into contracts with one other.The Coase theorem is the proposition that if private parties can bargain without cost over theallocation of resources, they can solve the problem of externalities on their own.Private economic participants are sometimes unable to solve the problems caused by anexternality because of transaction costs or because bargaining breaks down. This is mostlikely when the number of interested parties is large.Questions for Review1. Examples of negative externalities include pollution, barking dogs, and consumption ofalcoholic beverages. Examples of positive externalitiesinclude the restoration of historicbuildings, research into new technologies, and education. (Many other examples of negativeand positive externalities are possible.)2. Figure 1 illustrates the effect of a negative externality. The equilibrium quantity provided bythe market is Q market. Because of the externality, the social cost of production is greater thanthe private cost of production, so the social-cost curve is above the supply curve. The optimalquantity for society is Q optimum. The private market produces too much of the good becauseQ market is greater than Q optimum.Figure 13. The patent system helps society solve the externality problem from technology spillovers. Bygiving inventors exclusive use of their inventions for a certain period, the inventor cancapture much of the economic benefit of the invention. In doing so, the patent systemencourages research and technological advance, which benefits society through spillovereffects.Chapter 10/Externalities ?1914. Corrective taxes are taxes enacted to correct the effects ofa negative externality. Economistsprefer corrective taxes over regulations as a way to protect the environment from pollutionbecause they can reduce pollution at a lower cost to society.A tax can be set to reducepollution to the same level as a regulation. The tax has the advantage of letting the marketdetermine the least expensive way to reduce pollution. The tax gives firms incentives todevelop cleaner technologies to reduce the taxes they have to pay.5. Externalities can be solved without government intervention through moral codes and socialsanctions, charities, merging firms whose externalities affect each other, or by contract.6. According to the Coase theorem, you and your roommate will bargain over whether yourroommate will smoke in the room. If you value clean air morethan your roommate valuessmoking, the bargaining process will lead to your roommate not smoking. But if yourroommate values smoking more than you value clean air, the bargaining process will lead toyour roommate smoking. The outcome is efficient as long as transaction costs do not preventan agreement from taking place. The solution may be reached by one of you paying off theother either not to smoke or for the right to smoke.Quick Check Multiple Choice1. c2. b3. a4. c5. b6. cProblems and Applications1. The Club conveys a negative externality on other car owners because car thieves will notattempt to steal a car with The Club visibly in place. This means that they will move on toanother car. The Lojack system conveys a positive externality because thieves do not knowwhich cars have this technology. Therefore, they are less likely to steal any car. Policyimplications include a subsidy for car owners that use the Lojack technology or a tax onthose who use The Club.2. a. Fire extinguishers exhibit positive externalities becauseeven though people buy them fortheir own use, they may prevent fire from damaging the property of others.192 ? Chapter 10/ExternalitiesFigure 2b. Figure 2 illustrates the positive externality from fire extinguishers. Notice that the social-value curve is above the demand curve and the social-cost curve is the same as the supply curve.c. The market equilibrium level of output is denoted Q market and the efficient level of outputis denoted Q optimum . The quantities differ because in deciding to buy fire extinguishers, people don't account for the benefits they provide to others.d. A government policy that would result in the efficient outcome would be to subsidizepeople $10 for every fire extinguisher they buy. This would shift the demand curve up to the social-value curve, and the market quantity would increase to the optimum quantity. 3. a. The extra traffic is a negative externality because the social cost is greater than theprivate cost..b. Figure 3 shows the market for theater tickets. Because there is no external benefit, thesocial-value curve is the same as the demand curve in this case. However, the social-cost curve lies $5 above the supply curve at each quantity. The efficient level of output occurs where the social-value curve (which is demand in this case) and the social-cost curve intersect..Figure 3optimum market Price of TicketsChapter 10/Externalities ?193c. This is a positive externality because the social value of theater tickets is greater than theprivate value in this case.d. Figure 4 shows both the positive and the negative externalities.Figure 4e. A tax of $3 per ticket will lead to the efficient outcome. The market equilibrium quantitywill be equal to the social optimum.4. a. The market for alcohol is shown in Figure5. The social-value curve is the same as thedemand curve in this case. The social-cost curve is above the supply curve because ofthe negative externality from increased motor vehicle accidents caused by those whodrink and drive. The market equilibrium level of output is Q market and the efficient level of output is Q optimum.b. The triangular area between points A, B, and C represents the deadweight loss of themarket equilibrium. This area shows the amount by which social costs exceed socialvalue for the quantity of alcohol consumption beyond the efficient level.Figure 5194 ?Chapter 10/Externalities5. a. It is efficient to have different amounts of pollution reduction at different firms becausethe costs of reducing pollution differ across firms. If all firms were made to reducepollution by the same amount, the costs would be low at some firms and prohibitivelyhigh at others, imposing a greater burden overall.b. Command-and-control approaches that rely on uniformpollution reduction among firmsgive the firms no incentive to reduce pollution beyond the mandated amount. Instead,every firm will reduce pollution by just the amount required and no more.c. Corrective taxes or tradable pollution rights give firms greater incentives to reducepollution. Firms are rewarded by paying lower taxes or spending less on permits if theyfind methods to reduce pollution, so they have the incentive to engage in research onpollution control. The government does not have to figure out which firms can reducepollution the most?it lets the market give firms the incentive to reduce pollution on theirown.6. a. A t a price of $1.50, each Whovillian will consume 4 bottles of Zlurp. Eac h consumer’stotal willingness to pay is $14 (= $5 + $4 + $3 + $2). The total spent by each Whovillianon Zlurp is $6 (= $1.50 ? 4). Therefore, each consumer receives $8 in consumer surplus(=$14 ? $6).b. Total surplus would fall by $4 to $4.c. If Cindy Lou only consumes 3 bottles of Zlurp, her consumer surplus is $4.50. Herwillingness to pay for 3 bottles is $5 + $4 + $3 = $12. She pays $1.50 x 3 = $4.50 andthe externality is $1 x 3 = $3. Thus, Cindy Lou's consumer surplus is $12 - $4.50 - $3.00= $4.50. Cindy’s decision increases consumer surplus in Whoville by $0.50 ($4.50-$4.00).d. The $1 tax raises the price of a bottle of Zlurp to $2.50. (The entire tax will be borne byconsumers because supply is perfectly elastic.) Each resident will purchase only 3 bottlesat the higher price and each consumer’s total willingness to pay is now $12 (= $5 + $4 +$3). Each resident pays $7.50 (= $2.50 ? 3). Therefore, each resident receives $4.50($12-$7.50) in consumer surplus.Because each bottle has an external cost of $1, the per-resident external cost is $3 ($1per bottle x 3 bottles). The government collects $3 per resident in revenue. Total surpluswith the tax is equal to $4.50 - $3.00 + $3.00 = $4.50.e. Yes, because total surplus is now higher than before the tax.7. a. The externality is noise pollution. Ringo’s consumption of rock and roll music affectsLuciano, but Ringo does not consider that in deciding how loudly he plays his music.b. The landlord could impose a rule that music could not be played above a certain decibellevel. This could be inefficient because there would be no harm done by Ringo playinghis music loud if Luciano is not home.c. Ringo and Luciano could negotiate an agreement that might, for example, allow Ringo toplay his music loudly at certain times of the day. They mightnot be able to reach anagreement if the transaction costs are high or if bargaining fails because each holds outfor a better deal.Chapter 10/Externalities ?195 8. a. An improvement in the technology for controlling pollution would reduce the demand forpollution rights, shifting the demand curve to the left. Figure 6 illustrates what wouldhappen if there were a corrective tax, while Figure 7 shows the impact if there were afixed supply of pollution permits. In both figures, the curve labeled D1 is the originaldemand for pollution rights and the curve labeled D2 is the new demand for pollutionrights after the improvement in technology.Figure 6b. With a corrective tax, the price of pollution remains unchanged and the quantity ofpollution declines, as Figure 6 shows. With pollution permits, the price of pollutiondeclines and the quantity of pollution is unchanged, as Figure 7 illustrates.Figure 79. a. In terms of economic efficiency in the market for pollution, it does not matter if thegovernment distributes the permits or auctions them off, as long as firms can sell thepermits to each other. The only difference would be that the government could makemoney if it auctioned the permits off, thus allowing it to reduce taxes, which would help196 ?Chapter 10/Externalitiesreduce the deadweight loss from taxation. There could also be some deadweight lossoccurring if firms use resources to lobby for additional permits.b. If the government allocated the permits to firms who did not value them as highly asother firms, the firms could sell the permits to each other so they would end up in thehands of the firms who value them most highly. Thus, the allocation of permits amongfirms would not matter for efficiency. But it would affect the distribution of wealth,because those who got the permits and sold them would be better off.10. a. The firms with the highest cost of reducing pollution will buy permits rather than reducetheir pollution. Firms that can sell their permits for more than it costs them to reducetheir pollution will sell.Because firm B faces the highest costs of reducing pollution, $25 per unit, it will keep itsown 40 permits and buy 40 permits from the other firms, so that it can still pollute 80units. Thus, firm B does not reduce its pollution at all.Of the two remaining firms, firm A has the higher cost of reducing pollution so it willkeep its own 40 permits and reduce its pollution by 30 units at a cost of $20 x 30 units =$600.Firm C sells all 40 of its permits to firm B and reduces its pollution by 50 units at a cost of$10 × 50 = $500. The total cost of pollution reduction is。

The text discusses ways that international transactions differfrom domestic ones.i. International trade requires that transactions be conductedbetween twocurrencies mediated by an exchange rate. Domestic transactions are conductedin a single currency.ii. Commercial policies that operate to restrict international transactions cannot, ingeneral, be imposed on domestic trade. Such policies include tariffs, quotas,voluntary export restraints, export subsidies, and exchange controls.iii. Countries pursue different domestic macroeconomic policieswhich result indivergent rates of economic growth, inflation, and unemployment.iv. More statistical data exist on the nature, volume, and value of internationaltransactions than exist in domestic trade.v. Factors of production are more mobile domestically than internationally.vi. Countries exhibit different demand patterns, sales techniques,and marketingrequirements. Many of these are due to culture and custom. Someresult fromdifferences in government regulations. Included here are health, safety,environmental, and technical rules.2. The real volume of world exports grew at an annual rate of more than 6 percent between1950 and 2000. Global output grew at an annual rate of 4 percent. Export growth inexcess of output growth reflects the increased openness to trade of many countries.3. The United States is a relatively closed economy since the share of trade in GDP issmaller than that of most other industrial nations. In 2000, U.S. exports of goods andservices were 11 percent of GDP. The U.S. economy is less dependent on the foreignsector than other major economies, but to say that foreign trade is of no consequence is anexaggeration. The U.S. economy has become increasingly open and, therefore, moreimpacted by trade developments over time. This trend is likely to continue. Curtailingimports would, for example, have a big effect on consumers' ability to buy some goods----------------------- Page 2-----------------------(e.g. tropical products) and would raise the prices of others. The absence of certain keycommodities and material inputs would greatly disrupt areas of U.S. industry.4. a. Export industries send a substantial share of their output abroad. Ratios ofexports to GDP are much higher than the average ratio for all industries. Netexporting industries are those for which exports exceed imports. U.S. netexporting industries include farm products, chemicals, certain types of machinery,and aerospace products.b. Import-competing industries are domestic industries that sharethe domesticmarket with a substantial import presence. These activities haveratios ofimports to GDP that are much higher than the average ratio for all industries.U.S. import-competing industries include fuels, automobiles,clothing, footwear,and iron and steel.c. Nontraded goods are those which, because of their nature and characteristics, arenot easily exported or imported. Examples are hair-dressing, movie theaters,meals, construction activity, and health-care.5. Table 1.3 contains figures on the trade structure of the U.S. and Japan. The U.S. is a netexporter of food, certain ores, chemicals, and other machinery and transport equipment,and is a net importer of raw materials, mining products, fuels, nonferrous metals, iron andsteel, semimanufactures, office and telecommunications equipment, automotive products,textiles and clothing, and other consumer goods. Japan is a net exporter of iron and steel,chemicals, semimanufactures, office and telecommunications equipment, automotiveproducts, other machinery and transport equipment, and other consumer goods. Importsexceed exports in food, raw materials, and textiles and clothing.----------------------- Page 3-----------------------Chapter 2 Why Nations TradeReview Questions::::1( a. In what sense are the cost data of footnote 4 related to the figures of scheme 1?b. Based on the figures of footnote 4, determine the:Direction of trade once it develops.Limits to mutually beneficial trade.Limits to a sustainable exchange trade.2. Evaluate the following statements:a. In international trade, domestic cost ratios determine the limits of mutually beneficial trade,whereas demand considerations show where, within these limits, the actual exchange ratio will lie.b. Comparative advantage is a theoretical concept. It cannot be used to explain any real-worldphenomena.c. The opening up of trade raises the price of export goods; hence trade is inflationary.d. The concept of absolute advantage offers explainations for East Germany’s high unemploymentrates in the 1990s.3. a. Use the theory of comparative advantage to explain why it pays for:The USA to export grains and import oil.Russia to export oil and import grains.b. Why does the popular press believe that grain exports are inflnationary? What is wrongwith this porposition?Condensed Answers to Review Questions:1. a. Scheme 1 is based on labor productivity comparisons, while Footnote 4presentsper unit cost data. Production cost ratios are inversely related to productivitymeasures.b. i. Textiles will be exported from the U.K. and wheat from the U.S.ii. The U.S. will trade only if one yard of textiles costs less than3 bushels ofwheat. The U.K. will trade only if 1 yard of textiles can be exchangedfor more than 2 bushels of wheat.iii. The value of the ? must be between $1 and $1.502. a. Consider Figure 2.2. The domestic cost ratios define limits of mutually beneficialtrade. Within the region of mutually beneficial trade the actual exchange rate willbe determined by the relative intensity of each country's demand for the othercountry's product. A full analysis requires an understanding of reciprocal demandcurves, but the following general principle might help heuristically. If the Britishare more eager to buy U.S. wheat than the Americans are eager for British textiles,the exchange ratio falls close to the U.K. domestic cost ratio and the U.S. can beviewed as capturing a greater share of the gains from trade.b. Since the real world does not conform to the convenienttwo-country, two-goodassumptions, the simple theoretical model is not immediately applicable.However, we can generalize the model to many goods and many nations. Thefundamental truth remains. Countries export those goods in which their relativeproduction costs are lower and import those goods for which the relative costs arehigher.----------------------- Page 4-----------------------c. While trade tends to raise the prices of exportables in the domestic economy, theeffect of trade is to lower the average price level of all goods. Trade givesconsumers an opportunity to consume at lower world prices. Many goods will becheaper when purchased from foreign supply sources. Trade also conveysprocompetitive effects, stimulates the adoption of new technologies, and allowsfirms to achieve efficient scale production levels. Thus, trade is anti-inflationary.d. The reunification of the Germany economy in 1990 was undertaken on the basisthat a unit of the deutschmark, the West German currency, should be equal in valueto a unit of the ostmark, the East German currency. At this exchange rate, goodsproduced in East Germany were almost universally more expensive to producethan their counterparts in the West. Labor productivity in East Germanmanufacturing was found to be about 35% of the West German level. Underthese conditions the East German manufacturing sector collapsed. Investors werereluctant to purchase East German factories and large scale closures and dismissalsresulted.3. a. The U.S. enjoys a comparative advantage in grains. It also produces oil, but will gain byspecializing in grain production and using proceeds of exported agriculturalproducts to purchase oil from nations that produce oil relatively more efficiently.Russia is relatively more efficient in the production of oil and will gain bypurchasing grain from the U.S. in exchange for oil.b. The popular press asserts that by exporting grain from the U.S. (say to the former U R)we are lowering the domestic supply of grain and raising the domestic U.S. price of grain. Sincegrain is an important ingredient in many food products, grain exports are believed to increase theprice of those products. However, the price of grain is determined in world markets. U.S.exports alone cannot permanently raise the domestic U.S. price. If the domestic U.S. grainpricerose above the world price, the U.S. would be a net importer of grains and the domestic price wouldfall.----------------------- Page 5-----------------------Chapter 3 The Commodity Composition of TradeReview Questions::::1( Does the factor proportions theory provide a good explanation of intraindustry trade? Ifnot, can you outline an alternative explaination for the growing phenomenon?2( Explain the dynamic nature of comparative advantage using Japan’s experience as anexample.3( Once the United States acquires a comparative advantage in jet aircraft production it canbe sure of a dominant position in the global market forever. Do you agree with thisstatement? Explain.Condensed Answers to Review Questions1. The factor proportions theory is better suited to explain interindustry trade, or the exchangebetween countries of totally different commodities, than intraindustry trade, which is thetwo-way trade of similar commodities. The growth of intraindustry trade is greatest inimperfectly competitive industries characterized by economies of scale. Here, scaleeconomies force firms in each industry to specialize in a narrow range of products withineach industry to achieve efficient scale operations. Intraindustry specialization combinedwith diverse consumer tastes gives rise to two-way trade within the same industryclassification.2. Japan's comparative advantage in the immediate post-war period was in labor intensivegoods. The high level of saving and investment transformed Japan into a relatively capitalabundant country. Its advantage in the labor-intensive industries was lost as wages rose.Moreover, Japan increased its technological capability through high spending on R&D.Now Japan's advantage lies in the production of high-tech, capital intensive goods similar tothe U.S. This in large part explains the increasing trade friction between the twocountries.3. Once the U.S. acquires a comparative advantage in jet aircraft, it is likely to enjoy a dominantposition in the global marketplace for years, but not forever. Jet aircraft production is characterizedby huge economies of scale due largely to research and development costs. High capitalrequirements and scale economies pose large entry barriers. It is extremely difficult for a countryto enter into aircraft production once the U.S. has the lead. The new firm would initially have asmall market share and would be unable to compete on a cost basis. The new market entrant wouldrequire considerable government support and encouragement. This was the case with the EuropeanAirbus.----------------------- Page 6-----------------------Chapter 4 Protection of Domestic Industries: The TariffReview Questions::::1( A tariff on textiles is equivalent to a tax on consumers and a subsidy to the textileproducers and workers.2( Explain the concept of effective rate of protection.a. What does the effective rate on final goods depend upon and how?b. In what way does the effective rate analysis help to illuminate these policy issues:Deepening of production in LDCsEscalation of tariff rates by degree of processing in industrial countries3. A tariff lowers the real income of the country, while at the same time it distributes income fromconsumers to the governments and to the import-competing industry.Condensed Answers to Review Questions:1. The effect of a tariff is comparable to the combined effects of a tax on consumers and a subsidy toproducers. Using Figure 4.3, one can show a tariff results in a transfer of resources from theconsumers (who lose P P fd ) to the producers (who gain P P ec). With a non-prohibitive tariff, the2 3 2 3government will also gain revenue efmn. Whether the two schemes are equivalent depends on theexact nature of the tax and subsidy scheme.2. a. The effective rate of protection measures the percentage increase in domesticvalue added per unit of output made possible by tariffs on the output and onmaterial inputs. Determinants of the effective rate include thetariff on the finalproduct, tariffs on the imported material inputs, and the free trade value added perunit of output which is influenced by intermediate input coefficients. Effectiverates are positively related to the tariff on the final product and negatively related toboth tariffs on imported inputs and the free trade value added. A derivation ofthe formula appears in footnote 10, and footnote 12 interprets that formula.b. "Deepening" of production in LDCs involves import substitution industrializationpolicy. A final assembly plant is given a protective tariff and imported inputs areaccorded duty free treatment. As a second stage, the LDC begins to deepenproduction by manufacturing inputs and according them protection. By imposingtariffs on imported inputs, the LDC is reducing effective protection for the finalgood.Because of relatively high rates of protection on finished goods and low protectionon unfinished goods and raw materials, effective tariff rates in developed countriesmay be as much as double their nominal counterparts. Developing countriesmaintain that such tariff structures fatally harm their efforts to increase exports offinished manufactures.3. Again using Figure4.3, the loss in real income is shown by triangles cen and mfd.Redistribution has been given in 8a.----------------------- Page 7-----------------------Chapter 5 Nontariff Barriers (NTBs) to TradeReview Question::::Suppose the USA steel industry is seeking protection from foreign imports. Compare andcontrast the following measures of restricting steel industries: a tariff, a quota, and voluntaryexport restraints.Condensed Answers to Review Question:There are a variety of ways in which a tariff may be considered to be less harmful than an equivalentquota:i. The revenue effect. Tariffs provide revenue. Quotas do not automatically providerevenue. Under a quota, revenue accrues to holders of import licenses.Depending on the quota scheme, licenses may be held by domestic importers, foreign exporters, foreign governments, or domestic officialswho may use them to encourage bribery. Only through auctioning or selling licenses can the government capture quota rents.ii. Performance under demand and supply changes. Any amount of imports can enterunder a tariff, but with a quota import volumes are fixed. When demandgrows, or there is a shortfall in supply, the quota does not permit a quantityadjustment. The domestic price can depart significantly from the worldprice. Under a tariff, the domestic price cannot rise above the worldprice by more than the tariff rate. Thus, a tariff is less harmful than aquota.iii. Impact on Exporters. When a tariff is levied on an imported good it is usually rebatedwhen the good is exported. The same is not true for a quota. Quotas maytherefore be more harmful to export performance.iv. Curbing monopoly power. Quotas curtail monopoly power less than an equivalent tariff.v. Terms of Trade Effects. Quotas provide no incentive for exporting nations to absorb partof the price increase; tariffs do if the exporting nation wishes to retainmarket share.vi. Quality Upgrading. Quotas give an incentive for the exporting country to engage in qualityupgrading. Ad valorem tariffs do not provide an incentive for this behavior but specific duties do.VERs share all of the undesirable effects of quotas. When the exporter does the restricting, there isno opportunity to sell import licenses. Quota rents accrue toforeign exporters orgovernments under a VER. Therefore, VERs are more costly to society than anequivalent quota with licenses sold or a tariff. Quantitative restrictions like VERsare discriminatory. VERs are also hard to monitor. Since shipments from thirdparty countries are unrestricted, transshipment throughnonrestricted countries is amajor problem. One advantage of VERs is they do not invite retaliation sincethey are profitable to foreign exporters and governments.Tariffs, quotas and VERs may be equivalent in terms of effects on the domestic price and thevolumeof imports. This may be shown using diagram 5-1. However, there are important differencesdiscussed in 1a. above.----------------------- Page 8-----------------------Chapter 6 International and Regional Trade Organizations Among Developed CountriesReview Questions::::1. Explain the following terms:Trade creation of a customs union.Trade diversion of a customs union.2.What are the conflicts between the WTO and the environmental movement?Condensed Answers to Review Questions:1. Trade creation refers to the replacement of high cost production in each member by importsfrom another member. This effect is favorable to world welfare. Tradediversion is the diversion of trade from a nonmember to a higher cost member.This is unfavorable because it reduces worldwide resource allocative efficiency(See Figure 4-8).The basic approach to calculating welfare effects associated with customs union formation is toconstruct hypothetical estimates of what member country trade patterns wouldhave been in the absence of integration, comparing these with actual trade flows,and attributing any difference to integration. Effects ofintegration can be isolatedby using trade flow data pertaining to nonmember "normalizer" countries over thesame period to suggest what trade patterns would have been expected for memberswithout integration. Assume, in the absence of integration, both total (internalplus external) and external member imports would have grown at the same rates asthe corresponding imports in the normalizer. The normalizer's external importsrefer to its imports from third countries (i.e. intra-trade is excluded). Thenormalizer's internal imports are imports of normalizer countries from each other(e.g. intra-trade). The preintegration member country total import level ismultiplied by the corresponding normalizer import growth rate to yield an estimateof hypothetical total imports without integration. When compared with actualtotal imports, an estimate of trade creation is obtained. Trade diversion isestimated by multiplying the member country preintegration external import levelby the normalizer's rate of change of external imports to yield hypothetical membercountry external imports. The excess of hypothetical over actual external importsconstitutes trade diversion. The European Union (EU) is a customs unioncomprised of 15 West European countries.2. WTO rules often conflict with both international environmental agreements and nationalenvironmental laws. For example, a 1991 GATT panel upheld a Mexican challenge to aU.S. law banning importation of tuna caught indolphin-killing purse-seine nets.GATT/WTO provisions are concerned with products and not production methods.----------------------- Page 9-----------------------Chapter 7 International Mobility of Productive FactorsReview Question::::What is the meaning of DFI?
