国际经济学克鲁格曼课后习题答案章集团标准化办公室：[VV986T-J682P28-JP266L8-68PNN]第一章练习与答案1．为什么说在决定生产和消费时，相对价格比绝对价格更重要？答案提示：当生产处于生产边界线上，资源则得到了充分利用，这时，要想增加某一产品的生产，必须降低另一产品的生产，也就是说，增加某一产品的生产是有机会机本（或社会成本）的。
生产可能性边界上任何一点都表示生产效率和充分就业得以实现，但究竟选择哪一点，则还要看两个商品的相对价格，即它们在市场上的交换比率。
相对价格等于机会成本时，生产点在生产可能性边界上的位置也就确定了。
所以，在决定生产和消费时，相对价格比绝对价格更重要。
2．仿效图1—6和图1—7，试推导出Y商品的国民供给曲线和国民需求曲线。
答案提示：3．在只有两种商品的情况下，当一个商品达到均衡时，另外一个商品是否也同时达到均衡？试解释原因。
答案提示：4．如果生产可能性边界是一条直线，试确定过剩供给（或需求）曲线。
答案提示：5．如果改用Y商品的过剩供给曲线（B国）和过剩需求曲线（A国）来确定国际均衡价格，那么所得出的结果与图1—13中的结果是否一致？6．答案提示：国际均衡价格将依旧处于贸易前两国相对价格的中间某点。
7．说明贸易条件变化如何影响国际贸易利益在两国间的分配。
答案提示：一国出口产品价格的相对上升意味着此国可以用较少的出口换得较多的进口产品，有利于此国贸易利益的获得，不过，出口价格上升将不利于出口数量的增加，有损于出口国的贸易利益；与此类似，出口商品价格的下降有利于出口商品数量的增加，但是这意味着此国用较多的出口换得较少的进口产品。
对于进口国来讲，贸易条件变化对国际贸易利益的影响是相反的。
8．如果国际贸易发生在一个大国和一个小国之间，那么贸易后，国际相对价格更接近于哪一个国家在封闭下的相对价格水平？答案提示：贸易后，国际相对价格将更接近于大国在封闭下的相对价格水平。
国际经济学(克鲁格曼)教材答案
Chapter 31．Home has 1200 units of labor available. It can produce two goods, apples and bananas. The unit labor requirement in apple production is 3, while in banana production it is 2. a ．Graph out the production possibilities frontier:b ．What is the opportunity cost of apples in terms of bananas?5.1=LbLa a a c ．In the absence of trade, what would the price of apples in terms of bananas be?In the absence of trade, since labor is the only factor of production and supply decisions aredetermined by the attempts of individuals to maximize their earnings in a competitive economy, only when Lb La b a /a a /P P =will both goods be produced. So 1.5 /P P b a =2．Home is as described in problem 1. There is now also another country, Foreign, with alabor force of 800. Foreign ’s unit labor requirement in apple production is 5, while in banana production it is 1.a ．Graph Foreign ’s production possibilities frontier:b ．Construct the world relative supply curve.Home's PPF 0200400600800200400600800Q apple Q banana Foreign's PPF0200400600800100080160240320400Q*apple Q*banana3．Now suppose world relative demand takes the following form: Demand for apples/demandfor bananas = price of bananas/price of apples.a ．Graph the relative demand curve along with the relative supply curve:a b b a /P P /D D =∵When the market achieves its equilibrium, we have 1b a )(D D -**=++=ba b b a a P P Q Q Q Q ∴RD is a hyperbola xy 1=b ．What is the equilibrium relative price of apples?The equilibrium relative price of apples is determined by the intersection of the RD and RScurves.RD: yx 1= RS: 5]5,5.1[5.1],5.0(5.0)5.0,0[=∈=⎪⎩⎪⎨⎧+∞∈=∈y y y x x x ∴25.0==y x∴2/=b P a P e ec ．Describe the pattern of trade.∵b a b e a e b a P P P P P P ///>>**∴In this two-country world, Home will specialize in the apple production, export apples and import bananas. Foreign will specialize in the banana production, export bananas and import apples.d ．Show that both Home and Foreign gain from trade.International trade allows Home and Foreign to consume anywhere within the coloredlines, which lie outside the countries ’ production possibility frontiers. And the indirect method, specializing in producing only one production then trade with other country, is a more efficient method than direct production. In the absence of trade, Home could gain three bananas by foregoing two apples, and Foreign could gain by one foregoing five bananas. Trade allows each country to trade two bananas for one apple. Home could then gain four bananas by foregoing two apples while Foreign could gain one apple by foregoing only two bananas. So both Home and Foreign gain from trade.4．Suppose that instead of 1200 workers, Home had 2400. Find the equilibrium relative price. What can you say about the efficiency of world production and the division of the gains from trade between Home and Foreign in this case?RD: yx 1= RS: 5]5,5.1[5.1],1(1)1,0[=∈=⎪⎩⎪⎨⎧+∞∈=∈y y y x x x ∴5.132==y x ∴5.1/=b P a P e eIn this case, Foreign will specialize in the banana production, export bananas and import apples. But Home will produce bananas and apples at the same time. And the opportunity cost of bananas in terms of apples for Home remains the same. So Home neither gains nor loses but Foreign gains from trade.5．Suppose that Home has 2400 workers, but they are only half as production in both industries as we have been assuming, Construct the world relative supply curve and determine the equilibrium relative price. How do the gains from trade compare with those in the case described in problem 4?In this case, the labor is doubled while the productivity of labor is halved, so the ＂effective labor＂remains the same. So the answer is similar to that in 3. And both Home and Foreign can gain from trade. But Foreign gains lesser compare with that in the case 4.6．”Korean workers earn only $ an hour; if we allow Korea to export as much as it likes to the United States, our workers will be forced down to the same level. You can’t import a $5 shirt without importing the $ wage that goes with it.” Discuss.In fact, relative wage rate is determined by comparative productivity and the relative demand for goods. Korea’s low wage reflects the fact that Korea is less productive than the United States in most industries. Actually, trade with a less productive, low wage country can raise the welfare and standard of living of countries with high productivity, such as United States. Sothis pauper labor argument is wrong.7．Japanese labor productivity is roughly the same as that of the United States in the manufacturing sector (higher in some industries, lower in others), while the United States, is still considerably more productive in the service sector. But most services are non-traded. Some analysts have argued that this poses a problem for the United States, because our comparative advantage lies in things we cannot sell on world markets. What is wrong with this argument?The competitive advantage of any industry depends on both the relative productivities of the industries and the relative wages across industries. So there are four aspects should be taken into account before we reach conclusion: both the industries and service sectors of Japan and U.S., not just the two service sectors. So this statement does not bade on the reasonable logic. 8．Anyone who has visited Japan knows it is an incredibly expensive place; although Japanese workers earn about the same as their . counterparts, the purchasing power of their incomes is about one-third less. Extend your discussing from question 7 to explain this observation. (Hint: Think about wages and the implied prices of non-trade goods.) The relative higher purchasing power of U.S. is sustained and maintained by its considerably higher productivity in services. Because most of those services are non-traded, Japanese could not benefit from those lower service costs. And U.S. does not have to face a lower international price of services. So the purchasing power of Japanese is just one-third of their U.S. counterparts.9．How does the fact that many goods are non-traded affect the extent of possible gains from trade?Actually the gains from trade depended on the proportion of non-traded goods. The gains will increase as the proportion of non-traded goods decrease.10．We have focused on the case of trade involving only two countries. Suppose that there are many countries capable of producing two goods, and that each country has only one factor of production, labor. What could we say about the pattern of production and in this case? (Hint: Try constructing the world relative supply curve.)Any countries to the left of the intersection of the relative demand and relative supply curves export the good in which they have a comparative advantage relative to any country to the right of the intersection. If the intersection occurs in a horizontal portion then the country with that price ratio produces both goods.Chapter 41． In the United States where land is cheap, the ratio of land to labor used in cattle rising ishigher than that of land used in wheat growing. But in more crowded countries, where land is expensive and labor is cheap, it is common to raise cows by using less land and more labor than Americans use to grow wheat. Can we still say that raising cattle is land intensive compared with farming wheat? Why or why not?The definition of cattle growing as land intensive depends on the ratio of land to labor used inproduction, not on the ratio of land or labor to output. The ratio of land to labor in cattle exceeds the ratio in wheat in the United States, implying cattle is land intensive in the United States. Cattle is land intensive in other countries too if the ratio of land to labor in cattle production exceeds the ratio in wheat production in that country. The comparison between another country and the United States is less relevant for answering the question.2． Suppose that at current factor prices cloth is produced using 20 hours of labor for eachacre of land, and food is produced using only 5 hours of labor per acre of land.a. Suppose that the economy ’s total resources are 600 hours of labor and 60 acres ofland. Using a diagram determine the allocation of resources.5TF LF /TF LF /QF)(TF / /QF)(LF aTF / aLF 20TC LC /TC LC /QC)(TC / /QC)(LC aTC / aLC =⇒===⇒==We can solve this algebraically since L=LC+LF=600 and T=TC+TF=60. The solution is LC=400, TC=20, LF=200 and TF=40.b. Now suppose that the labor supply increase first to 800, then 1000, then 1200 hours. Using a diagram like Figure4-6, trace out the changing allocation of resources.

What would happen if the labor supply were to increase even further?At constant factor prices, some labor would be unused, so factor prices would have tochange, or there would be unemployment.3. “The world ’s poorest countries cannot find anything to export. There is no resource thatis abundant — certainly not capital or land, and in small poor nations not even labor is abundant.” Discuss.The gains from trade depend on comparative rather than absolute advantage. As to poor countries, what matters is not the absolute abundance of factors, but their relative abundance. Poor countries have an abundance of labor relative to capital when compared to more developed countries.4. The U.S. labor movement — which mostly represents blue-collar workers rather thanprofessionals and highly educated workers — has traditionally favored limits on imports form less-affluent countries. Is this a shortsighted policy of a rational one in view of the interests of union members? How does the answer depend on the model of trade?In the Ricardo ’s model, labor gains from trade through an increase in its purchasing power. This result does not support labor union demands for limits on imports from less affluent countries.In the Immobile Factors model labor may gain or lose from trade. Purchasing power in terms of one good will rise, but in terms of the other good it will decline.The Heckscher-Ohlin model directly discusses distribution by considering the effects of trade on the owners of factors of production. In the context of this model, unskilled U.S. labor loses from trade since this group represents the relatively scarce factors in this country. The results from the Heckscher-Ohlin model support labor union demands for import limits. 5. There is substantial inequality of wage levels between regions within the United States. Labor Land Cloth Food0l 800 0l 1000 0l 1200For example, wages of manufacturing workers in equivalent jobs are about 20 percent lower in the Southeast than they are in the Far West. Which of the explanations of failure of factor price equalization might account for this? How is this case different from the divergence of wages between the United States and Mexico (which is geographically closer to both the . Southeast and the Far West than the Southeast and Far West are to each other)?When we employ factor price equalization, we should pay attention to its conditions: both countries/regions produce both goods; both countries have the same technology of production, and the absence of barriers to trade. Inequality of wage levels between regions within the United States may caused by some or all of these reasons.Actually, the barriers to trade always exist in the real world due to transportation costs. And the trade between U.S. and Mexico, by contrast, is subject to legal limits; together with cultural differences that inhibit the flow of technology, this may explain why the difference in wage rates is so much larger.6.Explain why the Leontief paradox and the more recent Bowen, Leamer, andSveikauskas results reported in the text contradict the factor-proportions theory.The factor proportions theory states that countries export those goods whose production is intensive in factors with which they are abundantly endowed. One would expect the United States, which has a high capital/labor ratio relative to the rest of the world, to export capital-intensive goods if the Heckscher-Ohlin theory holds. Leontief found that the United States exported labor-intensive goods. Bowen, Leamer and Sveikauskas found that the correlation between factor endowment and trade patterns is weak for the world as a whole.The data do not support the predictions of the theory that countries' exports and imports reflect the relative endowments of factors.7.In the discussion of empirical results on the Heckscher-Ohlin model, we noted thatrecent work suggests that the efficiency of factors of production seems to differ internationally. Explain how this would affect the concept of factor price equalization.If the efficiency of the factors of production differs internationally, the lessons of the Heckscher-Ohlin theory would be applied to “effective factors” which adjust for the differences in technology or worker skills or land quality (for example). The adjusted model has been found to be more successful than the unadjusted model at explaining the pattern of trade between countries. Factor-price equalization concepts would apply to the effective factors. A worker with more skills or in a country with better technology could be considered to be equal to two workers in another country. Thus, the single person would be two effective units of labor. Thus, the one high-skilled worker could earn twice what lower skilled workers do and the price of one effective unit of labor would still be equalized.chapter 81. The import demand equation, MD, is found by subtracting the home supply equation from the home demand equation. This results in MD = 80 - 40 x P. Without trade, domestic prices and quantities adjust such that import demand is zero. Thus, the price in the absence of trade is2.2. a. Foreign's export supply curve, XS, is XS = -40 + 40 x P. In the absence of trade, the price is 1.b. When trade occurs export supply is equal to import demand, XS = MD. Thus, using theequations from problems 1 and 2a, P = , and the volume of trade is 20.3. a. The new MD curve is 80 - 40 x (P+t) where t is the specific tariff rate, equal to . (Note: in solving these problems you should be careful about whether a specific tariff or ad valorem tariff is imposed. With an ad valorem tariff, the MD equation would be expressed as MD =80-40 x (1+t)P). The equation for the export supply curve by the foreign country is unchanged. Solving, we find that the world price is $, and thus the internal price at home is $. The volume of trade has been reduced to 10, and the total demand for wheat at home has fallen to 65 (from the free trade level of70). The total demand for wheat in Foreign has gone up from 50 to 55.b. andc. The welfare of the home country is best studied using the combined numerical andgraphical solutions presented below in Figure 8-1. Home SupplyHome Demanda b c d e P T =1.7550556070QuantityPrice P W =1.50P T*=1.25where the areas in the figure are:a: 55 (55-50) .5(55-50) (65-55) .5(70-65) (65-55) surplus change: -(a+b+c+d)=. Producer surplus change: a=. Government revenue change: c+e=5. Efficiency losses b+d are exceeded by terms of trade gain e. [Note: in the calculations for the a, b, and d areas a figure of .5 shows up. This is because we are measuring the area of a triangle, which is one-half of the area of the rectangle defined by the product of the horizontal and vertical sides.]4. Using the same solution methodology as in problem 3, when the home country is very small relative to the foreign country, its effects on the terms of trade are expected to be much less. The small country is much more likely to be hurt by its imposition of a tariff. Indeed, this intuition is shown in this problem. The free trade equilibrium is now at the price $ and the trade volume is now $.With the imposition of a tariff of by Home, the new world price is $, the internal home price is $, home demand is units, home supply is and the volume of trade is . When Home is relatively small, the effect of a tariff on world price is smaller than when Home is relatively large. When Foreign and Home were closer in size, a tariff of .5 by home lowered world price by 25 percent, whereas in this case the same tariff lowers world price by about 5 percent. The internal Home price is now closer to the free trade price plus t than when Home was relatively large. In this case, the government revenues from the tariff equal , the consumer surplus loss is , and the producer surplus gain is . The distortionary losses associated with the tariff (areas b+d) sum to and the terms of trade gain (e) is . Clearly, in this small country example the distortionary losses from the tariff swamp the terms of trade gains. The general lesson is the smaller the economy,the larger the losses from a tariff since the terms of trade gains are smaller.5. The effective rate of protection takes into consideration the costs of imported intermediate goods. In this example, half of the cost of an aircraft represents components purchased from other countries. Without the subsidy the aircraft would cost $60 million. The European value added to the aircraft is $30 million. The subsidy cuts the cost of the value added to purchasers of the airplane to $20 million. Thus, the effective rate of protection is (30 - 20)/20 = 50%.6. We first use the foreign export supply and domestic import demand curves to determine the new world price. The foreign supply of exports curve, with a foreign subsidy of 50 percent per unit, becomes XS = -40 + 40(1+ x P. The equilibrium world price is and the internal foreign price is . The volume of trade is 32. The foreign demand and supply curves are used to determine the costs and benefits of the subsidy. Construct a diagram similar to that in the text and calculate the area of the various polygons. The government must provide - x 32 = units of output to support the subsidy. Foreign producers surplus rises due to the subsidy by the amount of units of output. Foreign consumers surplus falls due to the higher price by units of the good. Thus, the net loss to Foreign due to the subsidy is + - = units of output. Home consumers and producers face an internal price of as a result of the subsidy. Home consumers surplus rises by 70 x .3 + .5 (6= while Home producers surplus falls by 44 x .3 + .5(6 x .3) = , for a net gain of units of output.7. At a price of $10 per bag of peanuts, Acirema imports 200 bags of peanuts. A quota limiting the import of peanuts to 50 bags has the following effects:a. The price of peanuts rises to $20 per bag.b. The quota rents are ($20 - $10) x 50 = $500.c. The consumption distortion loss is .5 x 100 bags x $10 per bag = $500.d. The production distortion loss is .5 x50 bags x$10 per bag = $250.。

克鲁格曼国际经济学课后答案【篇一：克鲁格曼《国际经济学》(国际金融)习题答案要点】lass=txt>第12章国民收入核算和国际收支1、如问题所述，gnp仅仅包括最终产品和服务的价值是为了避免重复计算的问题。
在国民收入账户中，如果进口的中间品价值从gnp中减去，出口的中间品价值加到gnp中，重复计算的问题将不会发生。
例如：美国分别销售钢材给日本的丰田公司和美国的通用汽车公司。
其中出售给通用公司的钢材，作为中间品其价值不被计算到美国的gnp中。
出售给日本丰田公司的钢材，钢材价值通过丰田公司进入日本的gnp，而最终没有进入美国的国民收入账户。
所以这部分由美国生产要素创造的中间品价值应该从日本的gnp中减去，并加入美国的gnp。
2、（1）等式12-2可以写成ca?(sp?i)?(t?g)。
美国更高的进口壁垒对私人储蓄、投资和政府赤字有比较小或没有影响。
（2）既然强制性的关税和配额对这些变量没有影响，所以贸易壁垒不能减少经常账户赤字。
不同情况对经常账户产生不同的影响。
例如，关税保护能提高被保护行业的投资，从而使经常账户恶化。
（当然，使幼稚产业有一个设备现代化机会的关税保护是合理的。
）同时，当对投资中间品实行关税保护时，由于受保护行业成本的提高可能使该行业投资下降，从而改善经常项目。
一般地，永久性和临时性的关税保护有不同的效果。
这个问题的要点是：政策影响经常账户方式需要进行一般均衡、宏观分析。
3、（1）、购买德国股票反映在美国金融项目的借方。
相应地，当美国人通过他的瑞士银行账户用支票支付时，因为他对瑞士请求权减少，故记入美国金融项目的贷方。
这是美国用一个外国资产交易另外一种外国资产的案例。
（2）、同样，购买德国股票反映在美国金融项目的借方。
当德国销售商将美国支票存入德国银行并且银行将这笔资金贷给德国进口商（此时，记入美国经常项目的贷方）或贷给个人或公司购买美国资产（此时，记入美国金融项目的贷方）。
最后，银行采取的各项行为将导致记入美国国际收支表的贷方。

See Figure 10.8. See Figure 11.9. See Figure 12.10. See Figure 13 on page 67.11. See Figure 14.12. See Figure 15.13.The United States has become the most competitive economy in the world since the early1990’s while the data in Table 7.3 refers to the 1965-1990 period.14.The data in Table 7.4 seem to indicate that China had a comparative advantage incapital-intensive commodities and a comparative disadvantage in unskilled-labor intensive commodities in 1973. This was very likely due to the many trade restrictions and subsidies, which distorted the comparative advantage of China.Its true comparative advantage became evident by 1993 after China had started to liberalize its economy.App. 1a. See Figure 16.1b. For production and consumption to actually occur at the newequilibrium point after the doubling of K in Nation 2, we mustassume either than commodity X is inferior or that Nation 2 is toosmall to affect the relative commodity prices at which it trades.1c. Px/Py must rise (i.e., Py/Px must fall) as a result of growth only.Px/Py will fall even more with trade.1. If the supply of capital increases in Nation 1 in the production of commodity Yonly, the VMPLy curve shifts up, and w rises in both industries. Some labor shifts to the production of Y, the output of Y rises and the output of X falls, r falls, and Px/Py is likely to rise.2. Capital investments tend to increase real wages because they raise the K/L ratioand the productivity of labor. Technical progress tends to increase K/L and realwages if it is L-saving and to reduce K/L and real wages if it is K-saving. Multiple-Choice Questions1.

Doubling only the amount of L available under constant returns to scale:a. less than doubles the output of the L-intensive commodity*b. more than doubles the output of the L-intensive commodityc. doubles the output of the K-intensive commodityd. leaves the output of the K-intensive commodity unchanged4. The Rybczynski theorem postulates that doubling L at constant relative commodity prices:a. doubles the output of the L-intensive commodity*b. reduces the output of the K-intensive commodityc. increases the output of both commoditiesd. any of the above5. Doubling L is likely to:a. increases the relative price of the L-intensive commodityb. reduces the relative price of the K-intensive commodity*c. reduces the relative price of the L-intensive commodityd. any of the above6.Technical progress that increases the productivity of L proportionately more than the productivity of K is called:*a. capital savingb. labor savingc. neutrald. any of the above7. A 50 percent productivity increase in the production of commodity Y:a. increases the output of commodity Y by 50 percentb. does not affect the output of Xc. shifts the production frontier in the Y direction only*d. any of the above8. Doubling L with trade in a small L-abundant nation:*a. reduces the nation's social welfareb. reduces the nation's terms of tradec. reduces the volume of traded. all of the above9. Doubling L with trade in a large L-abundant nation:a. reduces the nation's social welfareb. reduces the nation's terms of tradec. reduces the volume of trade*d. all of the above10.If, at unchanged terms of trade, a nation wants to trade more after growth, then the nation's terms of trade can be expected to:*a. deteriorateb. improvec. remain unchangedd. any of the above11. A proportionately greater increase in the nation's supply of labor than of capital is likely to result in a deterioration in the nation's terms of trade if the nation exports:a. the K-intensive commodity*b. the L-intensive commodityc. either commodityd. both commodities12. Technical progress in the nation's export commodity:*a. may reduce the nation's welfareb. will reduce the nation's welfarec. will increase the nation's welfared. leaves the nation's welfare unchanged13.

Prove geometrically that mutually advantageous trade between the two nations is possible.Note: Your answer should show the autarky (no-trade) and free-trade points of production and consumption for each nation, the gains from trade of each nation,and express the equilibrium condition that should prevail when trade stops expanding.)Ans.: See Figure 1 on page 74.Nations 1 and 2 have different production possibilities curves and different community indifference maps. With these, they will usually end up with different relative commodity prices in autarky, thus making mutually beneficial trade possible.In the figure, Nation 1 produces and consumes at point A and Px/Py=P A in autarky, while Nation 2 produces and consumes at point A' and Px/Py=P A'. Since P A < P A',Nation 1 has a comparative advantage in X and Nation 2 in Y. Specialization inproduction proceeds until point B in Nation 1 and point B' in Nation 2, at which P B=P B' and the quantity supplied for export of each commodity exactly equals the quantity demanded for import. Thus, Nation 1 starts at point A in production and consumption in autarky, moves to point B in production, and by exchanging BC of X for CE of Y reaches point E in consumption. E > A since it involves more of both X and Y and lies on a higher community indifference curve. Nation 2 starts at A' in production and consumption in autarky, moves to point B' in production, and by exchanging B'C' of Y for C'E' of X reaches point E'in consumption (which exceeds A').At Px/Py=P B=P B', Nation 1 wants to export BC of X for CE of Y, while Nation 2 wants to export B'C' (=CE) of Y for C'E' (=BC) of X. Thus, P B=P B'is the equilibrium relative commodity price because it clears both (the X and Y) markets.3.Draw a figure showing: (1) in Panel A a nation's demand and supply curve for Atraded commodity and the nation's excess supply of the commodity, (2) in Panel C the trade partner's demand and supply curve for the same traded commodity and its excess demand for the commodity, and (3) in Panel B the supply and demand for the quantity traded of the commodity, its equilibrium price, and why a price above or below the equilibrium price will not persist. At any other price, QD QS, and P will change to P2.Ans. See Figure 2 on page 74.The equilibrium relative commodity price for commodity X (the traded commodityexported by Nation 1 and imported by Nation 2) is P2 and the equilibrium quantityof commodity X traded is Q2.4.a) Identify the conditions that may give rise to trade between two nations.b) What are some of the assumptions on which the Heckscher-Ohlin theory isbased?c) What does this theory say about the pattern of trade and effect of trade on factorprices?Ans. a) Trade can be based on a difference in factor endowments, technology, or tastes between two nations. A difference either in factor endowments or technology results in a different production possibilities frontier for each nation, which, unless neutralized by a difference in tastes, leads to a difference in relative commodity price and mutually beneficial trade. If two nations face increasing costs and have identical production possibilities frontiers but different tastes, there will also be a difference in relative commodity prices and the basis for mutually beneficial trade between the two nations. The difference in relative commodity prices is then translated into a difference in absolute commodity prices between the two nations, which is the immediate cause of trade.b) The Heckscher-Ohlin theory (sometimes referred to as the modern theory – asopposed to the classical theory - of international trade) assumes that nations have the same tastes, use the same technology, face constant returns to scale (i.e., a given percentage increase in all inputs increases output by the same percentage) but differ widely in factor endowments. It also says that in the face of identical tastes or demand conditions, this difference in factor endowments will result in a difference in relative factor prices between nations, which in turn leads to a difference in relative commodity prices and trade. Thus, in the Heckscher-Ohlin theory, the international difference in supply conditions alone determines the pattern of trade. To be noted is that the two nations need not be identical in other respects in order for international trade to be based primarily on the difference in their factor endowments.c) The Heckscher-Ohlin theorem postulates that each nation will export thecommodity intensive in its relatively abundant and cheap factor and import the commodity intensive in its relatively scarce and expensive factor. As an important corollary, it adds that under highly restrictive assumptions, trade will completely eliminate the pretrade relative and absolute differences in the price of homogeneous factors among nations. Under less restrictive and more usual conditions, however, trade will reduce, but not eliminate, the pretrade differences in relative and absolute factor prices among nations. In any event, the Heckscher-Ohlin theory does say something very useful on how trade affects factor prices and the distribution of income in each nation. Classical economists were practically silent on this point.5. consumers demand more of commodity X (the L-intensive commodity) and less ofcommodity Y (the K- intensive commodity). Suppose that Nation 1 is India, commodity X is textiles, and commodity Y is food. Starting from the no-trade equilibrium position and using the Heckscher-Ohlin model, trace the effect of this change in tastes on India's(a) relative commodity prices and demand for food and textiles,(b) production of both commodities and factor prices, and(c) comparative advantage and volume of trade.(d) Do you expect international trade to lead to the complete equalization ofrelative commodity and factor prices between India and the United States?Why?Ans. a. The change in tastes can be visualized by a shift toward the textile axis in India's indifference map in such a way that an indifference curve is tangentto the steeper segment of India's production frontier (because of increasingopportunity costs) after the increase in demand for textiles. This will causethe pretrade relative commodity price of textiles to rise in India.b. The increase in the relative price of textiles will lead domesticproducers in India to shift labor and capital from the production of food tothe production of textiles. Since textiles are L-intensive in relation to food,the demand for labor and therefore the wage rate will rise in India. At thesame time, as the demand for food falls, the demand for and thus the priceof capital will fall. With labor becoming relative more expensive,producers in India will substitute capital for labor in the production of bothtextiles and food.Even with the rise in relative wages and in the relative price of textiles,India still remains the L-abundant and low-wage nation with respect to anation such as the United States. However, the pretrade difference in therelative price of textiles between India and the United States is nowsomewhat smaller than before the change in tastes in India. As a result thevolume of trade required to equalize relative commodity prices and hencefactor prices is smaller than before. That is, India need now export asmaller quantity of textiles and import less food than before for therelative price of textiles in India and the United States to be equalized.Similarly, the gap between real wages and between India and the UnitedStates is now smaller and can be more quickly and easily closed (i.e., witha smaller volume of trade).c. Since many of the assumptions required for the complete equalization ofrelative commodity and factor prices do not hold in the real world, greatdifferences can be expected and do in fact remain between real wages inIndia and the United States. Nevertheless, trade would tend to reduce thesedifferences, and the H-O model does identify the forces that must beconsidered to analyze the effect of trade on the differences in the relative andabsolute commodity and factor prices between India and the United States.5.(a) Explain why the Heckscher-Ohlin trade model needs to be extended.(b) Indicate in what important ways the Heckscher-Ohlin trade model can beextended.(c) Explain what is meant by differentiated products and intra-industry trade.Ans. (a) The Heckscher-Ohlin trade model needs to be extended because, while generally correct, it fails to explain a significant portion of international trade, particularly the trade in manufactured products among industrial nations.(b)The international trade left unexplained by the basic Heckscher-Ohlin trade modecan be explained by(1) economies of scale,(2) intra-industry trade, and(3) trade based on imitation gaps and product differentiation.(c)Differentiated products refer to similar, but not identical, products (such as cars,typewriters, cigarettes, soaps, and so on) produced by the same industry or broad product group. Intra-industry trade refers to the international trade in differentiated products.。

克鲁格曼《国际经济学》中文版·第九版课后习题答案
克鲁格曼《国际经济学》中文版·第九版课后习题答案克鲁格曼《国际经济学》中文版·第九版课后习题答案第一章练习与答案1．为什么说在决定生产和消费时，相对价格比绝对价格更重要？答案提示：当生产处于生产边界线上，资源则得到了充分利用，这时，要想增加某一产品的生产，必须降低另一产品的生产，也就是说，增加某一产品的生产是有机会机本（或社会成本）的。
生产可能性边界上任何一点都表示生产效率和充分就业得以实现，但究竟选择哪一点，则还要看两个商品的相对价格，即它们在市场上的交换比率。
相对价格等于机会成本时，生产点在生产可能性边界上的位置也就确定了。
所以，在决定生产和消费时，相对价格比绝对价格更重要。
2．仿效图1—6和图1—7，试推导出Y商品的国民供给曲线和国民需求曲线。
答案提示：3．在只有两种商品的情况下，当一个商品达到均衡时，另外一个商品是否也同时达到均衡？试解释原因。
答案提示：4．如果生产可能性边界是一条直线，试确定过剩供给（或需求）曲线。
答案提示：5．如果改用Y商品的过剩供给曲线（B国）和过剩需求曲线（A 国）来确定国际均衡价格，那么所得出的结果与图1—13中的结果是否一致？答案提示：国际均衡价格将依旧处于贸易前两国相对价格的中间某点。
6．说明贸易条件变化如何影响国际贸易利益在两国间的分配。
答案提示：一国出口产品价格的相对上升意味着此国可以用较少的出口换得较多的进口产品，有利于此国贸易利益的获得，不过，出口价格上升将不利于出口数量的增加，有损于出口国的贸易利益；与此类似，出口商品价格的下降有利于出口商品数量的增加，但是这意味着此国用较多的出口换得较少的进口产品。
对于进口国来讲，贸易条件变化对国际贸易利益的影响是相反的。
7．如果国际贸易发生在一个大国和一个小国之间，那么贸易后，国际相对价格更接近于哪一个国家在封闭下的相对价格水平？答案提示：贸易后，国际相对价格将更接近于大国在封闭下的相对价格水平。

This is not a core chapter and I would skip it except for section 6. Section 6 is animportant section and can be regarded as an extension ofChapter 9, which is a corechapter. Section 6 deals with a very important set of current events.2. Section 6 is a long section and may require two classes to be adequately presented. Iwould cover subsections a-d in one class and subsection e as well as both case studies in the second class. Case Studies 10-1 to 10-6 can be used for a very stimulating classdiscussion.3. While section 6 can be presented without covering the material in sections 1-5, someterms discussed in sections 1-5 (such as trade creation and trade diversion) need to bedefined.4. In a one-year course in international economics, I would cover the entire chapter. I wouldthen cover sections 10-1 to 10-3 in one class and sections 10-4 and 10-5 in the secondclass. In the first class, the most important aspect would be the presentation and clearexplanation of Figures 10-1 and 10-2.Answers to Problems:1. If Nation A imposes a 100 percent ad valorem tariff on imports of commodity X fromNation B and Nation C, Nation A will produce commodity X domestically because thedomestic price of commodity X is $10 as compared with the tariff-inclusive price of$16 if Nation A imported commodity X from Nation B and $12 if Nation A importedcommodity X from nation C.2. a) If Nation A forms a customs union with Nation B, NationA will import commodity (6920811.d oc) 10-2 Dominick SalvatoreX from Nation B at the price of $8 instead of producing it itself at $10 or importing itfrom Nation C at the tariff-inclusive price of $12.b) When Nation A forms a customs union with Nation B this would be a trade-creatingcustoms union because it replaces domestic production of commodity X at Px=$10with tariff-free imports of commodity X from Nation B at Px=$8.3. If Nation A imposes a 50 percent ad valorem tariff on imports of commodity X fromNation B and Nation C, Nation A will import commodity X from nation C at the tariff- inclusive price of $9 instead of producing commodity X itself or importing it fromNation B at the tariff-inclusive price of $12.4. a) If Nation A forms a customs union with Nation B, NationA will import commodityX from Nation B at the price of $8 instead of importing it from Nation C at the tariff-inclusive price of $9.b) When Nation A forms a customs union with Nation B this would be a trade-divertingcustoms union because it replaces lower-price imports of commodity X of $6 (fromthe point of view of Nation A as a whole) with higher priced imports of commodityX from Nation B at $8.Specifically, Nation A's importers do not import commodity X from Nation Cbecause the tariff-inclusive price of commodity X from Nation C is $9 as comparedwith the no-tariff price of $8 for imports of commodity X from Nation B. However,since the government of Nation A collects the $3 tariff per unit on imports ofcommodity X from Nation C, the net effective price for imports of commodity Xfrom Nation C is really $6 for Nation A as a whole.5. See Figure 10-1 in the text. Any figure similar to Figure 10-1 in the text would do.6. The welfare gains that Nation 2 receives from joining Nation 1 to form a customs unionis given by the sum of the areas of triangles CJM and BHN in Figure 10-1 in the text.Any similar figure and sum of corresponding triangles would, of course, be adequate.7. See Figure 10-2 in the text. Any figure similar to Figure 10-2 in the text would do.8. The welfare loss that Nation 2 receives from joining Nation 1 to form a customs unionis given by C'JJ'+B'HH'- MNH'J'=$11.25 in Figure 10-2 in the text.Any similar figure and sum of corresponding triangles minus the area of corresponding rectangle would, of course, be adequate.9. See Figure 1 and compare it to Figure 10-2.10. The net gain from the trade-diverting customs unionshown in Figure 1 is given byC'JJ'+B'HH'-MJ'H'N. As contrasted with the case in Figure 10-2, however, the sum (6920811.d oc) 10-3 Dominick Salvatore of the areas of the two triangles (measuring gains) is greater than the area the rectangle (measuring the loss). Thus, the nation would now gain from the formation of a custom union. Had we drawn the figure on graph paper, we would have been able to measure the net gain in monetary terms also.11. A trade-diverting customs union is more likely to lead toa welfare gain of a membernation (1) the smaller is the relative inefficiency of nation 3 with respect to nation 1,(2) the higher is the level of the tariff, and (3) the more elastic are Dx and Sx in nation2. These can seen by comparing Figure 10-2 in the text with Figure 1 on the next page.12. See Figure 2. The formation of the customs union has no effect.13. NAFTA created much more controversy because the very low wages in Mexico led togreat fears of large job losses in the U. S.14. The possible cost to the U.S. from EU92 arose from the increased efficiency andcompetitiveness of the E.U. The benefit arose because a more rapid growth in the EU spills into a greater demand for American products, which benefits the U. S.App. Compare points B' and H' in Figure 10-3 with the corresponding points inFigure 3.Multiple-choice Questions:1. Which of the following statements is correct?*a. In a customs union, member nations apply a uniform external tariffb. in a free-trade area, member nations harmonize their monetary and fiscal policiesc. within a customs union there is unrestricted factor movementd. a customs union is a higher form of economic integration than a common market2.

A trade-diverting customs union:a. increases trade among union members and with nonmember nationsb. reduces trade among union members and with nonmember nations*c. increases trade among members but reduces trade with non-membersd. reduces trade among union members but increases it with nonmembers5. A trade-diverting customs union results in:a. trade diversion onlyb. trade creation only*c. both trade creation and trade diversiond. we cannot say6. The formation of a trade-creating customs union where all economic resources of membernations are fully employed before and after the formation of the customs union leads to an:*a. increase in the welfare of member and nonmember nationsb. increase in the welfare of member nations onlyc. increase in the welfare of nonmember nations onlyd. increase or decrease in the welfare of member and nonmember nations7. A trade-diverting customs union:a. increases the welfare of member and nonmember nationsb. reduces the welfare of member and nonmember nationsc. increases the welfare of member nations but reduces that of nonmembers*d. reduces the welfare of nonmembers and may increase or reduce that of members8. A trade-diverting customs union is more likely to lead to trade creation:a. the lower are the pre-union trade barriers of the member countries*b. the lower are the customs union's barriers on trade with the rest of the worldc. the smaller is the number of countries forming the customs union and the smaller their sized. the more complementary rather than competitive are the economies of the nations forming the customs union9.

International Economics: Trade and Money
⏹Chapter Overview
The intent of this chapter is to provide both an overview of the subject matter of international economics and to provide a guide to the organization of the text. It is relatively easy for an instructor to motivate the study of international trade and finance. The front pages of newspapers, the covers of magazines, and the lead reports on television news broadcasts herald the interdependence of the U.S. economy with the rest of the world. This interdependence may also be recognized by students through their purchases of imports of all sorts of goods, their personal observations of the effects of dislocations due to international competition, and their experience through travel abroad.
The study of the theory of international economics generates an understanding of many key events that shape our domestic and international environment. In recent history, these events include the causes and consequences of the large current account deficits of the United States; the dramatic appreciation of the dollar during the first half of the 1980s followed by its rapid depreciation in the second half of the 1980s; the Latin American debt crisis of the 1980s and the Mexican crisis in late 1994; and the increased pressures for industry protection against foreign competition broadly voiced in the late 1980s and more vocally espoused in the first half of the 1990s. The financial crisis that began in East Asia in 1997 and spread to many countries around the globe and the Economic and Monetary Union in Europe highlighted the way in which various national economies are linked and how important it is for us to understand these connections. These global linkages have been highlighted yet again with the rapid spread of the financial crisis in the United States to the rest of the world. At the same time, protests at global economic meetings and a rising wave of protectionist rhetoric have highlighted opposition to globalization. The text material will enable students to understand the economic context in which such events occur.

Chapter 1 of the text presents data demonstrating the growth in trade and the increasing importance of international economics. This chapter also highlights and briefly discusses seven themes which arise throughout the book. These themes are (1) the gains from trade; (2) the pattern of trade; (3) protectionism; (4) the balance of payments; (5) exchange rate determination; (6) international policy coordination; and (7) the international capital market. Students will recognize that many of the central policy debates occurring today come under the rubric of one of these themes. Indeed, it is often a fruitful heuristic to use current events to illustrate the force of the key themes and arguments which are presented throughout the text.
