However, for the world as a whole the expansion of production of one product must involve a decrease in the availability of theother, so that it is not clear that trade is better for the world as a whole as compared to an initial situation of non-trade (but efficient production in each country). Are there in fact gains from trade for the world as a whole? Explain.Answe r: If we were to combine the production possibilityfrontiers of the two countries to create a single world production possibility frontier, then it is true thatany change in production points (from autarky to specialization with trade) would involve a tradeoff of one good for another from the world's perspective. In other words, the new solution cannot possibly involvethe production of more of both goods. However, since we know that each country is better off at the new solution, it must be true that the original points were not on the trade contract curve between the two countries, and it was in fact possible to make some people better off without making others worse off, so that the newsolution does indeed represent a welfare improvementfrom the world's perspective.QuestionStatus:Previous Edition24) It is generally claimed that a movement from autarky to freetrade consistent with Ricardian comparative advantageincreases the economic welfare of each of the trade partners.However, it may be demonstrated that under certaincircumstances, not everyone in each country is made betteroff. Illustrate such a case.Answe r: (a) If inter-generational, or economic growth considerations are taken into account, then a country may end up specializing in a good that has no or few growth linkages with the rest of the economy (e.g. an "enclave" sector).(b) If some of the residents of a country have tastes biased toward their exportable, then they may suffer due to the trade-affected increase in the market price of the exportable good.QuestionStatus:Previous Edition25) It is generally claimed that state trading, or centrallycontrolled trading will tend to reach a lower economicwelfare than would be reached by allowing market forces to determine trade flow directions and terms of trade.Illustrate a counter-example to this proposition.Answe r: In general, if we begin with any suboptimal distortion, the theory of the second best tells us that anadditional "distortion" may move a country in thecorrect direction of a welfare improvement. For example, If a country has an overvalued exchange rate (that is, its currency is overpriced in the foreign exchange markets), it is possible that it will find itself in an autarkic equilibrium (that is, it might "overpriceitself out of the international market"). In such a case it is easy to demonstrate that if the government exports the goods in which the country enjoys comparative advantage, and imports the other (bypassing market prices and mechanisms), the country's economic welfare will improve.Question Status:Previous Edition26) The Ricardian proposition that international trade willbenefit any country ("gains from trade") as long as theworld terms of trade do not equal its autarkic relativeprices is a straightforward and powerful concept.Nevertheless, it is impossible to demonstrate empirically.Why?Answe r: This is because there is no way of knowing exactly what are, or would have been, the autarky MRTs or MRSs. Thisis because there is no single example in the world of a country that is totally unengaged in international trade.QuestionStatus:Previous Edition27) Given the information in the table above. What is theopportunity cost of Cloth in terms of Widgets in Foreign?One half a widget.Answer:Previous EditionQuestionStatus:28) Given the information in the table above. If these twocountries trade these two goods in the context of theRicardian model of comparative advantage, then what is thelower limit of the world equilibrium price of widgets?Answe1/2 Cloths.r:Previous EditionQuestionStatus:29) Given the information in the table above.

国际经济学题库英文版
国际经济学题库(英文版)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 labor requirement 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, whenaLC/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 labor requirement in cheese and wine at Home and Foreign, respectively. L and L*are Home’s and Foreign’s laborforce. 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 income of capitalists increase, it can be shown as ↑M K P r ↑↑M K P r .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 between relative 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 w ere less capital-intensive than U.S. imports” is known as 里昂惕夫悖论 Leontief paradox .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） fromproduction 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 national welfarecan 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 politics29.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 bydomestic policies aimed directly at the problems ’ sources ;Second economists cannot diagnose market failure well enough to prescribe policy .33. International trade often produces losers as well as winners. In the actual politics of trade policy,exp 1exp orts importsI orts imports -=-+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 principle 36.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 whether it largely leads to trade creation or trade diversion .38.Trade policy in developing countries is concerned with two objectives （涉及两个目标）: promoting industrialization and Coping with the problem of the dual economy . industrialization 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 .Part Ⅱ. 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 relative 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 f orced 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 buthurts 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 r esource that is 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 trade. ( 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 tend 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 products 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 )54.Wh en a country borrows, it’s intertemporal PPF is biased toward Q P.( F )55.The relative price of future consumption goods Q P is (1+r). ( T )56.The dynamic path of TNC s’ enter foreign market：FDI→Export→Licence. (F )57.Tariffs may have very different effects on different stages of production of a good. ( 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 tari ff 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 higher incomes for farmers — they mean higher income for everyone who sell goods and services to the U.S. farm sector”.

国际经济学第三章课后习题答案
2.本国共有1200单位的劳动，能生产两种产品：苹果和香蕉。
苹果的单位产品劳动投入是3，香蕉的单位产品劳动投入是 2.a。
画出本国的生产可能性边界。
b.用香蕉衡量的苹果的机会成本是多少？c.贸易前，苹果对香蕉的相对价格是多少？为什么？a．b．c．在贸易前,当劳动是生产的唯一要素，且在竞争日益激烈的经济环境中，供给决策是由个人获得的最大收益决定时，只有当时，这两种货物才能被生产。
所以，教科书问题的答案1. a。
生产可能性曲线是一条直线,截获苹果轴在400(1200/3)和香蕉轴上600(1200/2)。
b。
机会成本的苹果,香蕉是3/2而言。
它需要3个单位的劳动收获一个苹果,但是只有两个单位的劳动收获一根香蕉。
如果一个人foregoes收获一个苹果,这释放3个单位的劳动。
这3个单位的劳动就能够被用来收获1.5香蕉。
c。
劳动力流动,保证了每一个环节上常见的工资和竞争保证了货物的价格等于他们的生产成本。
因此,相对价格的相对成本相等时,它等于倍的工资单位劳动条件为苹果的工资倍除以单位劳动要求香蕉。
由于工资是平等的交叉,价格比率之比相等单位劳动要求,为苹果每2是3个香蕉。
2,3,6,7,11,14]。
生产可能性曲线是线性的,在苹果和拦截800/5相当于160(轴)和拦截踩在香蕉轴等于800(800/1)。
b。
世界相对供给曲线,建立确定供应苹果相对于供应的香蕉在每个相对价格。
最低的相对价格,比如苹果是收获3苹果每2个香蕉。
供给曲线是平的相对这个价钱。
苹果的最大数量的价格提供3/2在家里是400所提供的同时,以这样的价格,外国的丰收,800香蕉和没有苹果给最大相对供应以这个价格的1 / 2。
这种相对供应价格之间3/2适用任何和五日。
的价格是5,两国将在收成苹果。
供给曲线是又相对平坦的5。
因此,相关的供给曲线是一步成型,公寓,租金价格相对而言3/2供应为0到1 / 2,垂直的,从3/2数量相对半上升到5元,然后再从半无限地来讲一个。

international（国际经济学）课后习题及答案----------------------- Page 1-----------------------Review Questions and Condensed Answers forInternational Trade TheoriesChapter 1 World Trade and the National EconomyReview Questions::::1( What features distinguish international from domestic transactions?2( What can you say about the growth of world trade in both nominal and real terms? Was itfaster than the growth of output?3( Evaluate the statement,” the United States is a closed economy, hence foreign trade is ofno consequence to it.”4( Distinguish between export industries, import-competing industries and nontraded goods.Give examples of each.5( Using the figure in table 1-3, what can you say about the trade structure of the USA andJapan.Condensed Answers to Review Questions::::1. 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? List some of the factors that induce companies to invest abroad.Condensed Answers to Review Question:Direct Foreign Investment refers to international capital movement that gives a company controlover a foreign subsidiary. It may be the purchase of an existing company, a substantial part of itsshares, or the establishment of a new enterprise. It should be contrasted with portfolio investmentthat gives, by and large, no control over foreign assets.The motives are diverse and any particular investment may involve one or more of the followingi. investment in extractive industries to secure raw material supplies;ii. investment in manufacturing industry to take advantage of cheaper foreign labor;iii. to locate production close to foreign markets and avoid transportation costs;iv. to take advantage of incentives offered by host countries;v. to circumvent tariff barriers;vi. changes in the exchange values of currencies; andvii. marketing considerations.。

To maximize its satisfaction, a nation will ensure that its terms-of-trade linea. is tangent to its production possibilities frontier at one point (production point) and also to the highest attainable indifference curve at another point (consumption point)b. is tangent to its production possibilities frontier and intersects an indifference curvec. intersects its production possibilities frontier and is tangent to an indifference curved. intersects its production possibilities frontier at one point and an indifference curve at another point6. Factor-price equalization predicts that with international tradea. the price of a nation’s abundant factor will rise and that of its scarce factor will fallb. the price of a nation’s abundant factor will fall and that of its scarce factor will risec. the prices of a nation’s abundant and scarce factors both will rised. the prices of a nation’s abundant and scarce factors both will fall7. The effective rate of protectiona. distinguishes between tariffs that are effective and those that are ineffectiveb. is the minimum level at which a tariff becomes effectiv e in limiting importsc. shows the increase in value-added for domestic production that a particular tariff structure makes possible, in percentage termsd. shows how effective a tariff is in raising revenue8.

In the first lecture of Chapter 3, I would cover Sections 1, 2, and3. Section 2 can becovered quickly, except for 2b, which requires careful explanation because of its subsequentimportance. Careful explanation is also required for 3b. I would assign Problems 1 and 2.2. In the second lecture, I would cover Sections 4, 5a, and 5b. Thisis the basic trade modeland it is essential for the student to master it completely. To this end, I would assign andgrade Problems 3 and 4.3. In the third lecture, I would cover the remainder of the chapter.The topics here representelaborations of the basic trade model. I would assign problems 5, 6, and 7 and go overproblem 7 in class even though its answer is also in the back of the book. I would make theAppendices optional for those students in the class who have had intermediate micro theory.Answer to Problems1. a) See Figure 1.b) The slope of the transformation curve increases as the nationproduces more of X anddecreases as the nation produces more of Y. These reflect increasing opportunity costs asthe nation produces more of X or Y.2. a) See Figure 2.We have drawn community indifference curves as downward or negatively sloped becauseas the community consumes more of X it will have to give up some of Y to remain onthe same indifference curve.b)The slope measures how much of Y the nation can give up byconsuming one more unitof X and still remain at the same level of satisfaction; the slope declines because the moreof X and the less of Y the nation is left with, the less satisfaction it receives fromadditional units of X and the more satisfaction it receives from each retained unit of Y.c) III > II to the right of the intersection, while II > III to the left.This is inconsistent because an indifference curve should show a given level of satisfaction.Thus, indifference curves cannot cross.3. a) See Figure 3 on page 22.b) Nation 1 has a comparative advantage in X and Nation 2 in Y.c) If the relative commodity price line has equal slope in both nations.4. a) See Figure 4.b) Nation 1 gains by the amount by which point E is to the right andabove point A andNation 2 by the excess of E' over A'. Nation 1 gains more from trade because the relativeprice of X with trade differs more from its pretrade price than for Nation 2.5. a) See Figure 5. In Figure 5, S refers to Nation 1's supplycurve of exports of commodity X, while D refers to Nation 2's demand curve for Nation 1's exports of commodity X. D and S intersect at point E, determining the equilibrium P B=Px/Py=1 and the equilibrium quantity of exports of 60X.b) At Px/Py=1 1/2 there is an excess supply of exports of R'R=30Xand Px/Py falls towardequilibrium Px/Py=1.c) At Px/Py=1/2, there is an excess demand of exports of HH'=80X and Px/Py risestoward Px/Py=1.6. The Figure in Problem 5 is consistent with Figure 3-4 in the text.From the left panel ofFigure 3-4, we see that Nation 1 supplies no exports of commodity X at Px/Py=1/4 (pointA). This corresponds with the vertical or price intercept of Nation 1's supply curve ofexports of commodity X (point A).The left panel of Figure 3-4 also shows that at Px/Py=1, Nation 1 is willing to export 60X(point E). The same is shown by Nation 1's supply curve of exports of commodity X.The other points on Nation 1's supply curve of exports in the figure of Problem 5 can alsobe derived from the left panel of Figure 3-4, but this is shown in Chapter 4 with offercurves.Nation 2's demand curve for Nation 1's exports ofcommodity X could be derived from theright panel of Figure 3-4, as shown in Chapter 4. What is important isthat we can use theD and S figure in Problem 5 to explain why the equilibrium relative commodity price withtrade is Px/Py=1 and why the equilibrium quantity traded of commodity X is 60 units inFigure 3-4.7. See Figure 6 on page 24.The small nation will move from A to B in production, exports X in exchange for Y so asto reach point E > A.8. a) The small nation specializes in the production of commodityX only until its opportunitycost and relative price of X equals P W. This usually occurs before the small nation hasbecome completely specialized in production.b) Under constant costs, specialization is always complete for the small nation.9. a) See Figure 7.b) See Figure 8.10. If the two community indifference curves had also been identical in Problem 9 the relativecommodity prices would also have been the same in both nations in the absence of trade andno mutually beneficial trade would be possible11. If production frontiers are identical and the communityindifference curves different in thetwo nations, but we have constant opportunity costs, there would be no mutually beneficialtrade possible between the two nations12. See Figure 1113. It is true that Mexico's wages are much lower than U.S. wages (about one fifth), but laborproductivity is much higher in the United States and so labor costs are not necessarilyhigher than in Mexico. In any event, trade can still be based on comparative advantage.App. 1. See Figure 12Commodity X is the L-intensive commodity in Nation 2 (as in Nation 1) because the production contract curve bulges toward the L- axis or is everywhere to the left of the diagonal.App. 2. Since L and K are released from the production of X in a higher ratio than are absorbed in the production of Y, wages fall in Nation 2. This leads to the substitution of L for K in the production of X and Y, so that the K/L ratio falls in the production of both commodities.Multiple-Choice Questions1.

They are entirely unrelated to individuals' community indifference curvesb. they cross, they cannot be used in the analysis*c. the problems arising from intersecting community indifference curves can be overcome by the application of the compensation principled. all of the above.8. Which of the following is not true for a nation that is in equilibrium in isolation?*a. It consumes inside its production frontierb. it reaches the highest indifference curve possible with its production frontierc. the indifference curve is tangent to the nation's production frontierd. MRT of X for Y equals MRS of X for Y, and they are equal to Px/Py9. If the internal Px/Py is lower in nation 1 than in nation 2 without trade:a. nation 1 has a comparative advantage in commodity Yb. nation 2 has a comparative advantage in commodity X*c. nation 2 has a comparative advantage in commodity Yd. none of the above10. Nation 1's share of the gains from trade will be greater:a. the greater is nation 1's demand for nation 2's exports*b. the closer Px/Py with trade settles to nation 2's pretrade Px/Pyc. the weaker is nation 2's demand for nation 1's exportsd. the closer Px/Py with trade settles to nation 1's pretrade Px/Py11. If Px/Py exceeds the equilibrium relative Px/Py with tradea. the nation exporting commodity X will want to export more of X than at equilibriumb. the nation importing commodity X will want to import less of X than at equilibriumc. Px/Py will fall toward the equilibrium Px/Py*d. all of the above12. With free trade under increasing costs:a. neither nation will specialize completely in productionb. at least one nation will consume above its production frontierc. a small nation will always gain from trade*d. all of the above13. Which of the following statements is false?a.The gains from trade can be broken down into the gains from exchange and the gains from specializationb. gains from exchange result even without specialization*c. gains from specialization result even without exchanged. none of the above14.

国际经济学课后答案
第三章复习题(1),本国共有1200单位的劳动，能生产两种产品：苹果和香蕉。
苹果的单位产品劳动投入是3，香蕉的单位劳动产品投入时2。
a.画出本国的生产可能性边界。
b.用香蕉衡量的苹果的机会成本是多少？c.贸易前，苹果对香蕉的相对价格是多少？为什么？答：a.本国的生产可能性边界曲线是一条直线，在400（1200/3)处与苹果轴相截，在600（1200/2）处与香蕉轴相截，如图2-7所示。
b.用香蕉衡量苹果的机会成本是3/2。
生产1单位苹果需要3单位的劳动，生产1单位香蕉需要2单位的劳动。
如果放弃1单位苹果的生产，这将释放出3单位的劳动。
这2单位的劳动可以被用来图2-7 本国生产可能生产3/2单位的香蕉。
c.劳动的流动性可以使得各个部门的工资趋同，竞争可以使得商品的价格等于它们的生产成本。
这样，相对价格等于相对成本，而相对成本等于工资乘以苹果的单位劳动产品投入。
因为各个部门工资相等，所以价格比率等于单位产品劳动投入的比率，即生产苹果所需的3单位劳动与生产香蕉所需的2单位劳动比率。
（2）假设本国的情况和习题1相同。
外国拥有800单位的劳动，外国苹果的单位劳动投入是5，香蕉的单位产品劳动投入是1。
a.画出外国的生产可能性边界。
b.画出世界相对供给曲线。
答：a.外国的生产可能性边界曲线是一条直线，在160（800/5）处与苹果轴相截，在800(800/1)处与香蕉轴相截。
如图2-8所示。
b.世界相对供给曲线可以由苹果和香蕉的相对价格和相对供给量绘出。
如图2-9。
从图2-9可以看出，苹果对香蕉的最低相对价格是3/2，在这个价格上，苹果的世界相对供给曲线是水平的。
在3/2的相对价格上，本国对苹果的最大供给量是400，外国对香蕉的供给量是800，这时，相对供给量为1/2。
只要相对价格保持在3/2和5之间，相对供给量就不变。
如果相对价格成为5，两个国家都会生产苹果，香蕉的产量为零。
这时，相对供给曲线是水平的。
所以，从图2-9中可以看出，相对价格为3/2时，相对供给在0到1/2之间；相对价格在3/2和5之间时，相对供给保持1//2不变；当相对价格为5时，相对供给从1/2图2-9 世界相对供图2-8 外国生产可能曲到无穷大。

However, for the world as a whole the expansion of production of one product must involvea decrease in the availability of the other, so that it is not clear that trade is better for the world as a whole ascompared to an initial situation of non-trade (but efficient production in each country). Are there in factgains from trade for the world as a whole? Explain.Answer: If we were to combine the production possibility frontiers of the two countries to create a single world production possibility frontier, then it is true that any change in production points (from autarky tospecialization with trade) would involve a tradeoff of one good for another from the world'sperspective. In other words, the new solution cannot possibly involve the production of more of bothgoods. However, since we know that each country is better off at the new solution, it must be true thatthe original points were not on the trade contract curve between the two countries, and it was in factpossible to make some people better off without making others worse off, so that the new solutiondoes indeed represent a welfare improvement from the world's perspective.Question Status: Previous Edition24) It is generally claimed that a movement from autarky to free trade consistent with Ricardian comparativeadvantage increases the economic welfare of each of the trade partners. However, it may be demonstrated that under certain circumstances, not everyone in each country is made better off. Illustrate such a case.Answer: (a) If inter-generational, or economic growth considerations are taken into account, then a country may end up specializing in a good that has no or few growth linkages with the rest of the economy(e.g. an "enclave" sector).(b) If some of the residents of a country have tastes biased toward their exportable, then they maysuffer due to the trade-affected increase in the market price of the exportable good.Question Status: Previous Edition25) It is generally claimed that state trading, or centrally controlled trading will tend to reach a lower economicwelfare than would be reached by allowing market forces to determine trade flow directions and terms of trade. Illustrate a counter-example to this proposition.Answer: In general, if we begin with any suboptimal distortion, the theory of the second best tells us that an additional "distortion" may move a country in the correct direction of a welfare improvement. Forexample, If a country has an overvalued exchange rate (that is, its currency is overpriced in the foreignexchange markets), it is possible that it will find itself in an autarkic equilibrium (that is, it might"overprice itself out of the international market"). In such a case it is easy to demonstrate that if thegovernment exports the goods in which the country enjoys comparative advantage, and imports theother (bypassing market prices and mechanisms), the country's economic welfare will improve.Question Status: Previous Edition26) The Ricardian proposition that international trade will benefit any country ("gains from trade") as long as theworld terms of trade do not equal its autarkic relative prices is a straightforward and powerful concept.Nevertheless, it is impossible to demonstrate empirically. Why?Answer: This is because there is no way of knowing exactly what are, or would have been, the autarky MRTs or MRSs. This is because there is no single example in the world of a country that is totally unengaged ininternational trade.Question Status: Previous Edition27) Given the information in the table above.

They often despair of even trying to attempt to build their industries unless it is done in anautarkic context, behind protectionist walls because they do not believe they can compete with moreproductive industries abroad. Discuss this issue in the context of the Ricardian model of comparativeadvantage.Answer: The Ricardian model of comparative advantage argues that every country must have a comparative advantage in some product (assuming there are more products than countries). However, theRicardian model is not a growth model, and cannot be used to identify growth nodes or linkages.Question Status: Previous Edition19) In 1975, wage levels in South Korea were roughly 5% of those in the United States. It is obvious that if theUnited States had allowed Korean goods to be freely imported into the United States at that time, this wouldhave caused devastation to the standard of living in the United States, because no producer in this countrycould possibly compete with such low wages. Discuss this assertion in the context of the Ricardian model ofcomparative advantage.Answer: Regardless of relative wage levels, the United States would be able to provide its populace with a higher standard of living than would be possible without trade. Also, low wages tend to be associatedwith low productivities.Question Status: Previous Edition20) The evidence cited in the chapter using the examples of the East Asia New Industrializing Countriessuggests that as international productivities converge, so do international wage levels. Why do you supposethis happened for the East Asian NICs? In light of your answer, what do you think is likely to happen to therelative wages (relative to those in the United States) of China in the coming decade? Explain your reasoning.Answer: Following the logic of the Ricardian model of comparative advantage, the East Asian countries played to their respective comparative advantages. This allowed the world demand to provide excessdemands for their relatively abundant labor, which in turn tended to raise these wages. If Chinafollows the same pattern, their wages levels should also be expected over time to converge to those intheir industrialized country markets.Question Status: Previous Edition3.5 Comparative Advantage with Many Goods1) The multi-good (2-country) model differs from the two country, two product model, in that in the former,。

Discuss.T heoretically, just as completely free trade consistent with Heckscher-Ohlin model (with no complete specialization) is associated with factor price equalization; so does completely free labor mobility. It therefore follows that if intra E.U. trade flourishes, as any restraints on trade there are abolished, the economic incentive for labor mobility will be removed. Since language and cultural differences remain, we would expect populations to tend to stay where they are.2.The two deadweight triangles are the Consumption distortion and Production distortionlosses. It is easy to understand why the Consumption distortion constitutes a loss for society. After all it raises the prices of goods to consumers, and even causes some consumers to drop out of the market altogether. It seems paradoxical that the Production distortion is considered an equivalent burden on society. After all, in this case, profits increase, and additional production (with itsassociated employment) comes on line. This would seem to be an offset rather than an addition to the burden or loss borne by society. Explain why the Production distortion is indeed a loss to society, and what is wrong with the logic that leads to the apparent paradox.T he Production Distortion represents an inefficient shift of societyʺs resources to produce a good, which it could not sell profitably at world prices. Since (with full employment assumed) these resources were formerly used to produce export goods, which could compete profitably, the net result is a loss in real income to the country.。

Why is it that an industry is operating under conditions of domestic internal scale economies (applies to firm in the country) - then the resultant equilibrium cannot be consistent with the pure competition model?2. Is it possible that if positive scale economies characterize an industry, that its equilibrium may be consistent with purely competitive conditions ? Explain how this could happen.3. If a scale economy is the dominant technological factor defining or establishing comparative advantage, then the underlying facts explaining why a particular country dominates world markets in some product may be pure chance, or historical accident. Explain, and compare this with the answer you would give for the Heckscher-Ohlin model of comparative advantage.4. It is possible that trade based on external scale economies may leave a country worse off than it would have been without trade. Explain how this could happen.5. If scale economies were not only external to firms, but were also external to individual countries. That is, the larger the worldwide industry (regardless of where firms or plants are located), the cheaper would be the per-unit cost of production.Describe what world trade would look like in this case.Quantitative/Graphing Problems1. The figure above represents the demand and cost functions facing a Brazilian Steel producing monopolist. If it were unable to export, and was constrained by its domestic market, what quantity would it sell at what price?2. Now the monopolist discovers that it can export as much as it likes of its steel at the world price of $5/ton. It will therefore expand for- export production up to the point where its marginal cost equals $5. How much steel will the monopolist sell, and at what price?3. Given the opportunity to sell at world prices, the marginal (opportunity) cost of selling a ton domestically is what?4. While selling exports it would also maximize its domestic sales by equating its marginal (opportunity) cost to its marginal revenue of $5. How much steel would the firm sell domestically, and at what price?5. The Brazilian firm is charging its foreign (U.S.) customers one half the price it is charging its domestic customers. Is this good or bad for the real income or economic welfare of the United States? Is the Brazilian firm engaged in dumping? Is this predatory behavior on the part of the Brazilian steel company?。

A nation maximizes satisfaction by reaching the highestpossible indifference curve, and in the absence of trade will produce where its production possibilitiesschedule is tangent to an indifference curve.3. The factor endowments model predicts thatinternational trade will tend to equalize the prices oftrade-able goods among nations, but to increase thewage gap between capital-abundant and labor-abundant nations.4. A tax of 10 percent on imports of shoes would be anexample of a specific tariff.5. An import quota will not raise the domestic price ofthe product as would a tariff, because it is not a tax onimports.6. In balance-of-payments account, a transaction resultingin receipt of a payment is recorded as a credit,whereas a transaction resulting in a payment to othernations is recorded as a debit.7. Because they do not include an exchange of goods orservices, unilateral transfers do not appear on anation's balance of payments account.8. David Hume was one of the first economists to provideanalytical support for mercantilist trade policies.9. A nation would be most likely to find its trade balanceimproving after a currency depreciation if that nation’sdemand for imports and foreign demand for its exportswas very inelastic.10.

Why is it that an industry is operating under conditions of domestic internal scale economies (applies to firm in the country) - then the resultant equilibrium cannot be consistent with the pure competition model?2. Is it possible that if positive scale economies characterize an industry, that its equilibrium may be consistent with purely competitive conditions ? Explain how this could happen.3. If a scale economy is the dominant technological factor defining or establishing comparative advantage, then the underlying facts explaining why a particular country dominates world markets in some product may be pure chance, or historical accident. Explain, and compare this with the answer you would give for the Heckscher-Ohlin model of comparative advantage.4. It is possible that trade based on external scale economies may leave a country worse off than it would have been without trade. Explain how this could happen.5. If scale economies were not only external to firms, but were also external to individual countries. That is, the larger the worldwide industry (regardless of where firms or plants are located), the cheaper would be the per-unit cost of production. Describe what world trade would look like in this case.Quantitative/Graphing Problems1. The figure above represents the demand and cost functions facing a Brazilian Steel producing monopolist. If it were unable to export, and was constrained by its domestic market, what quantity would it sell at what price?2. Now the monopolist discovers that it can export as much as it likes of its steel at the world price of $5/ton. It will therefore expand for- export production up to the point where its marginal cost equals $5. How much steel will the monopolist sell, and at what price?3. Given the opportunity to sell at world prices, the marginal (opportunity) cost of selling a ton domestically is what?4. While selling exports it would also maximize its domestic sales by equating its marginal (opportunity) cost to its marginal revenue of $5. How much steel would the firm sell domestically, and at what price?5. The Brazilian firm is charging its foreign (U.S.) customers one half the price it is charging its domestic customers. Is this good or bad for the real income or economic welfare of the United States? Is the Brazilian firm engaged in dumping? Is this predatory behavior on the part of the Brazilian steel company?。

Hence, as a policy framework, the disproportionate effect trade may have on real incomes of sectors, such as skilled-labor is quite useful both theoretically and practically (or polemically)2. International trade leads to complete equalization of factor prices. Discuss. This statement is typically ʹtrue . . . but.ʹ Under a strict and limited set of assumptions, such as the original Heckscher-O hlin model which excludes country specific technologies; non- homothetic tastes; factor intensity reversals; large country differences in (relative) factor abundance s, more factors than goods, and an equilibrium solution within the ʹcone of specializationʹ; then it may bedemonstrated that internal consistency demands that the above stated sentence isʹtrue.ʹ However, the minute one relaxes any of the above listed assumptions one may ea sily identify solutions, which contradict the factor price equalization theorem.3. If a scale economy is the dominant technological factor defining or establishing comparativeadvantage, then the underlying facts explaining why a particular country domina tes world markets in some product may be pure chance, or historical accident. E xplain, and compare this with the answer you would give for the Heckscher-Ohli n model of comparative advantage.T his statement is true, since the reason the seller is a monopolist may be that it happened to have been the first to produce this product in this country. It may ha ve no connection to any supply or demand related factors; nor to any natural or man-made availability. This is all exactly the opposite of the Heckscher-Ohlin Ne o-Classical modelʹs explanation of the determinants of comparative advantage.练习题三 Part A Multiple ChoiceB E D D A D A A AC C A BD D1) International borrowing and lending may be interpreted as one form ofA) intermediate trade.B) inter-temporal trade.C) trade in services.D) unrequited international transfers.E) None of the above.2) International free labor mobility will under all circumstancesA) increase total world output.B) improve the economic welfare of everyone.C) improve the economic welfare of workers everywhere.D) improve the economic welfare of landlords (or capital owners) everywhere.E) None of the above.3) International labor mobilityA) leads to wage convergence by raising wages in destination country and lowering in source country.B) is in accordance with the specific factors model.C) is in accordance with the Heckscher-Ohlin factor proportions model.D) leads to wage convergence by raising wages in source and lowering them in destin ation country.E) is in accordance with scale economy model.4) If initially wages are higher in Home than in Foreign, then a movement of wor kers from Foreign to Home willA) lower the marginal product of labor in Foreign.B) raise total product in Foreign.C) raise the income of land owners in Foreign.D) raise the income of land owners in Home.E) None of the above.5) A country that has a comparative advantage in future production of consumpti on goodsA) will tend to be an international borrower.B) will tend to have low real interest rates.C) will tend to be an international investor or lender.D) will tend to have good work ethics.

E) None of the above. PART B Short Question 1.It has been argued that even if intra-European Union labor mobility were to be c ompletely removed, one should not expect to observe massive, or even large reall ocations of populations with the E.U. Discuss.T heoretically, just as completely free trade consistent with Heckscher-Ohlin model (with no complete specialization) is associated with factor price equalizatio n; so does completely free labor mobility. It therefore follows that if intra E.U. tra de flourishes, as any restraints on trade there are abolished, the economic incenti ve for labor mobility will be removed. Since language and cultural differences re main, we would expect populations to tend to stay where they are.2. The two deadweight triangles are the Consumption distortion and Production distortion losses. It is easy to understand why the Consumption distortion constit utes a loss for society. After all it raises the prices of goods to consumers, and eve n causes some consumers to drop out of the market altogether. It seems paradoxi cal that the Production distortion is considered an equivalent burden on society. After all, in this case, profits increase, and additional production (with its associa ted employment) comes on line. This would seem to be an offset rather than an addition to the burden or loss borne by society. Explain why the Production distor tion is indeed a loss to society, and what is wrong with the logic that leads to the a pparent paradox.T he Production Distortion represents an inefficient shift of societyʺs resources to produce a good, which it could not sell profitably at world prices. S ince (with full employment assumed) these resources were formerly used to prod uce export goods, which could compete profitably, the net result is a loss in real i ncome to the country.练习题五：A E C A D C D D E D A D 1．Which of the following statements is the most accurate?

One reason f or these differences is that people living in different countries spend their income in di fferent ways. Because of this inherent difference among countries, certain baskets will be affected more by price changes given their consumptions basket. For example, con sumers in country, X, eats more fish relative to another country. More than likely, the government, upon determining a commodity basket to reflect preference, will have an overwhelming representation of fish in their basket. Any price level change in the fish market will be felt particularly by country X, and their overall price level will reflect t his. Thus, changes in the relative prices of basket components can cause relative PPP t o become distorted.14. Using a figure show that under full employment, a temporary fiscal expansion wo uld increase output (overemployment) but cannot increase output in the long run.A temporarily fiscal expansion will move the economy from DD1 to DD2, and outp ut increases. A permanent fiscal expansion will also shift the AA curve to the left and down. The nominal exchange rate appreciates, i.e. E decreases.15. Using the DD model, explain what happens to out put when Government demands increase. Use a figure to explain when it is taking place.T he figure below shows the G1 to G2 raises output at every level of the exchange rate . The change shifts the DD to the right. Which in turns increases output to Y2.[文档可能无法思考全面，请浏览后下载，另外祝您生活愉快，工作顺利，万事如意!]。
