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。

8．根据上一题的答案，你认为哪个国家在国际贸易中福利改善程度更为明显些？答案提示：小国。

【最新整理，下载后即可编辑】这是我在网上找的，大多数题目都有，朋友们可以参考一下！有一点不确定的是G—L指数，大家再上网查看看，是乘100还是乘1？希望可以给你们帮助，预祝大家顺利通过！第二章古典国际贸易理论在古典贸易模型中，假设A国有120名劳动力，B国有50名劳动力，如果生产棉花的话，A国的人均产量是2吨，B国也是2吨；要是生产大米的话，A国的人均产量是10吨，B国则是16吨。

画出两国的生产可能性曲线并分析两国中哪一国拥有生产大米的绝对优势？哪一国拥有生产大米的比较优势？思路：B国由于每人能生产16吨大米，而A国每人仅生产10吨大米，所以B国具有生产大米的绝对优势。

从两国生产可能性曲线看出A国生产大米的机会成本为0.2，而B国为0.125，所以B国生产大米的机会成本或相对成本低于A国，B国生产大米具有比较优势。

1.下表列出了加拿大和中国生产1单位计算机和1单位小麦所需的劳动时间。

假定生产计算机和小麦都只用劳动，加拿大的总劳动为600小时，中国总劳动为800小时。

（1）计算不发生贸易时各国生产计算机的机会成本。

（2）哪个国家具有生产计算机的比较优势？哪个国家具有生产小麦的比较优势？（3）如果给定世界价格是1单位计算机交换22单位的小麦，加拿大参与贸易可以从每单位的进口中节省多少劳动时间？中国可以从每单位进口中节省多少劳动时间？如果给定世界价格是1单位计算机交换24单位的小麦，加拿大和中国分别可以从进口每单位的货物中节省多少劳动时间？（4）在自由贸易的情况下，各国应生产什么产品，数量是多少？整个世界的福利水平是提高还是降低了？试用图分析。

（以效用水平来衡量福利水平）思路：（1）中国生产计算机的机会成本为100/4=25，加拿大为60/3=20（2）因为加拿大生产计算机的机会成本比中国低，所以加拿大具有生产者计算机的比较优势，中国就具有生产小麦的比较优势。

（3）如果各国按照比较优势生产和出口，加拿大进口小麦出口计算机，中国进口计算机出口小麦。

This is not a core chapter and I would omit it in a one-semester undergraduate course in international economics.2. If I were to cover this chapter, I would cover two sections in each of three lectures and assign the end-of-chapter problems.Answer to Problems1. See Figure 1.2. See Figure 2.3. See Figure 3.4. See Figure 4.5. An unexpected increase in prices in the face of sticky wages means that real wages temporarily fall. This leads firms to hire more workers and thus increase output in the short run. In the long-run, however, money wages fully adjust to (i.e., increase in the same proportion as) the increasein prices. As a result, real wages return to their previous higher level, firms reduce employment to their original lower level, and the nation's output returns to its lower long-runnatural level, but at the new higher price level.6. Starting from point C in Figure 19-3, an unexpected decrease in aggregate demand from AD' to AD causes prices to fall and firms to temporarily reduce their output, giving the new short-run equilibrium point where the AD' curve intersects the SRAS' curve. In the long run, however, as expected prices fall to match actual prices, the short-run aggregate supply curve shifts down by the amount of the price reduction (i.e., from SRAS' to SRAS) and defines new long- run equilibrium point E at the natural level of output YN, but lower price level of PE.Another way of saying this is that at point to the left of the LRAS curve, actual prices are lower than expected prices. Expected prices then fall and this shifts the SRAS curve downward until expected prices are equal to the lower actual prices, and the economy returns to its long-run natural level of output equilibrium.7. An unexpected decrease in aggregate demand causes prices to fall. If wages are sticky and do not immediately fall in the same proportion as the fall in prices, real wages will temporarily increase. This leads firms to hire fewer workers and thus reduce output in the short run. In the long-run, however, money wages fully adjust to (i.e., fall in the same proportion as) the fall in prices. As a result, real wages return to their previous lower level, firms increase employment to their original higher level, and the nation's output returns to its higher long-run or naturallevel, but at the new higher lower level.8. If the LM' curve intersected the IS' curve at a point below the BP' curve in the left panel of Figure 19-5, the interest rate in the nation would be lower than required for balance of payments equilibrium. The nation would then have a deficit in its balance of payments. Under a fixed exchange rate system, the deficit in the nation's balance of payments would result in an outflow of international reserves and thus a reduction in the nation's money supply, which would shift up the LM' curve sufficiently to intersect the IS' curve on the BP' curve, so that the nationwould be simultaneously in equilibrium in the goods and money markets and in the balance of payments, as at point E".9. See Figure 5.10. Starting from equilibrium in the goods and services sector, in the monetary sector, and in the balance of payments, an autonomous worsening of the nation's trade balance at unchanged domestic prices, causes the IS and BP curves to shift to the left and opens a deficit in the nation's balance of payments under fixed exchange rates. This leads to a leftward shift of the LM curve and a reduction in national income. Thus, the nation's aggregate demand curve shifts to the left.11. With flexible exchange rates, the autonomous worsening of the nation's trade balance at unchanged domestic prices, causes the IS and BP curves to shift to the left (just as in the case of fixed rates). Now, however, the tendency of the nation's balance of payments to go into deficit leads to a depreciation of the nation's currency and a deterioration in the nation's trade balance, so that the BP and IS curves shift to the left, back to their original position along the unchanged LM curve. Thus, the nation returns to the original equilibrium position and point on its original aggregate demand curve.12. Expansionary fiscal policy under fixed exchange rates or easy monetary policy under flexible rates can correct a recession but only the expense of higher prices or inflation. If prices are flexible downward in the nation, however, the recession can be corrected automatically and in a relatively short time by falling domestic prices, which would stimulate the domestic and foreign demand for the nation's goods and services. If domestic prices are sticky or not too flexible downward, however, relying on market force (i.e., falling prices in the nation) to automatically correct the recession may take too long, and this may justify the use of expansionary fiscal or monetary policies.13. The nation would reach the long-run equilibrium point where the AD' curve crosses the unchanged LRAS curve. The SRAS curve would also shift and cross the LRAS curve at the same point. The nation's natural level of output and employment would then be the same as before the supply (petroleum) shock, but prices would be higher.14. The concept of the natural rate of unemployment is useful as long as no structural changes take place in the economy. When structural changes do occur (and globalization may just be such a structural change), then the rate of natural unemployment will change. With globalization the natural rate of unemployment may well be 5 percent or lower in the United States today.Multiple-Choice Questions1.

It is included for more advanced students and for completeness.2.If I were to cover this chapter, I would present two sections in each of three lectures.Time permitting, I would, otherwise cover Sections 1 and 2, paying special attention to the Rybczynski theorem.Answer to Problems1. a) See Figure 1.b) See Figure 2c) See Figure 3.2. See Figure 4.3. a) See Figure 5.b) See Figure 6.c) See Figure 7.4. Compare Figure 5 to Figure 1.Compare Figure 6 to Figure 3.

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. Dynamic factors in trade theory refer to changes in:a. factor endowmentsb. technologyc. tastes*d. all of the above2. Doubling the amount of L and K under constant returns to scale:a. doubles the output of the L-intensive commodityb. doubles the output of the K-intensive commodityc. leaves the shape of the production frontier unchanged*d. all of the above.3. 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. Doubling K with trade in a large L-abundant nation:a. increases the nation's welfareb. improves the nation's terms of tradec. reduces the volume of trade*d. all of the above14. An increase in tastes for the import commodity in both nations:a. reduces the volume of trade*b. increases the volume of tradec. leaves the volume of trade unchangedd. any of the above15. An increase in tastes of the import commodity of Nation A and export in B:*a. will reduce the terms of trade of Nation Ab. will increase the terms of trade of Nation Ac. will reduce the terms of trade of Nation Bd. any of the aboveADDITIONAL ESSAYS AND PROBLEMS FOR PART ONE1.Assume that both the United States and Germany produce beef and computer chipswith the following costs:United States Germany(dollars) (marks)Unit cost of beef (B) 2 8Unit cost of computer chips (C) 1 2a) What is the opportunity cost of beef (B) and computer chips (C) in each country?b)In which commodity does the United States have a comparative cost advantage?What about Germany?c)What is the range for mutually beneficial trade between the United States andGermany for each computer chip traded?d)How much would the United States and Germany gain if 1 unit of beef isexchanged for 3 chips?Ans. a) In the United States:the opportunity cost of one unit of beef is 2 chips;the opportunity cost of one chip is 1/2 unit of beef.In Germany:the opportunity cost of one unit of beef is 4 chips;the opportunity cost of one chip is 1/4 unit of beef.b) The United States has a comparative cost advantage in beef with respect toGermany, while Germany has a comparative cost advantage in computer chips.c)The range for mutually beneficial trade between the United States and Germanyfor each unit of beef that the United States exports is2C < 1B < 4Cd) Both the United States and Germany would gain 1 chip for each unit of beeftraded.2.Given: (1) two nations (1 and 2) which have the same technology but differentfactor endowments and tastes, (2) two commodities (X and Y) produced under increasing costs conditions, and (3) no transportation costs, tariffs, or other obstructions to trade. 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.。

In the first lecture on Chapter 17 (a core chapter), I would cover sections 1 and 2 andassign problems 1 to 4. Section 2 is a review of principles of economics but myexperience is that the average student needs it to clearly understand the material in the rest of the chapter.2. In the second lecture, I would cover sections 3 and 4 and assign problems 3 to 8. Mostother texts do not deal with foreign trade multipliers in any great detail because of thedifficulty of deriving them. However, their meaning and use is important and they can s still be discussed without deriving them (their derivation is in section A17.1 of theappendix, which can be made optional for the best and most eager students in the class).3. In the third lecture, I would cover sections 5 and 6 and assign problems 9 to 14. Thesetwo sections are very important and difficult.Answer to Problems:1.

The X-M function would shift up as in Figure 9 without full employment. With fullemployment, the depreciation will result in inflation and a return to the condition ofFigure 8 (i.e., the X-M function would shift up and then down to its original position),unless domestic absorption is somehow reduced.13. One reason is that the government sector is not included. Another reason is if the nationis not in equilibrium.14. The advantages of automatic over policy adjustment to correct a trade disequilibrium are:(1) adjustment begins to operate even before the problem is recognized; (2) there are nopossibilities of policy mistakes; and (3) the adjustment will continue until the tradedisequilibrium is entirely eliminated. On the other hand, adjustment policies can only be enacted after the problem is recognized. There are then delays to enact policies and forthem to have effect. Thus, by the time adjustment policies become effective the nationmay not longer face the problem or may face the opposite problem. Wrong policies can also be adopted.App. 1a. ∆I + m*∆Y* = s∆Y + m∆Y∆I* + m∆Y = s*∆Y* + m*∆Y*∆X + m*∆Y* = s∆Y - m∆Y-∆X + m∆Y = (s*+m*)∆Y*(6921029.doc) 17-10 Dominick Salvatore-∆X + m∆Y = ∆Y*s* + m*∆X + m*(-∆X + m∆Y) = s∆Y + m∆Ys* + m*∆X + -m*∆X + m*m∆Y = (s + m)∆Ys* + m+s*∆X + m*∆X - m*∆X + m*m∆Y = (s + m)(s* + m*)∆Ys*∆X + m*m∆Y = (s + m)(s* + m*)∆Ys*∆X = [(s + m) (s* + m*) - m*m]∆Y∆X = [ ]∆Y s*∆Y = s* = 1∆X ss* + mm* + ms* + m*s - m*m s + m + m*s/s*b. k" = 1s + mthat is, k" is already a foreign repercussion.App. 2. Most petroleum exporting nations, notably Saudi Arabia, Libya, and Kuwait could not spend all of their petroleum earnings on increased imports from petroleum importing countries during the 1970s. Most unspent earnings were used for portfolio purchases inthe developed nations, especially in the U.S., through the Eurodollar market. At the sametime, most oil-importing nations deflated their economies to reduce their oil bill andbalance of payments difficulties. The sharp decline in petroleum since 1981completelyeliminated the excess earnings of most OPEC nations so that the transfer problemdisappeared.Multiple-choice Questions:1. In order to isolate the income adjustment mechanism, we assume that:a. the nation operates under a fixed exchange rate systemb. all prices, wages, and interest rates are constantc. the nation operates at less than full employment(6921029.doc) 17-11 Dominick Salvatore*d. all of the above2. The marginal propensity to consume measures:a. the ratio of imports to incomeb. the ratio of income to imports*c. the change in imports over the change in incomed. the change in income over the change in imports3. The income elasticity of imports is given by:a. the percentage change in income over the percentage change in importsb. the change in imports over the change in income*c. the marginal propensity to import over the average propensity to importd. the average propensity to import over the marginal propensity to import4. The equilibrium level of national income in an open economy is given by:a. I + X = S + Mb. X - M = S - Ic. I + (X-M) = S*d. all of the above5.

The S-I function rises because:a. rising I are subtracted from constant S*b. constant I are subtracted from rising Sc. rising I are subtracted from rising Sd. constant I are added to falling S(6921029.doc) 17-12 Dominick Salvatore8. An autonomous fall in M from a condition of equilibrium in national income and in thetrade balance results in the nation's income:a. rising and its trade balance turning to deficitb. falling and its trade balance turning into surplus*c. rising and its trade balance turning into surplusd. rising and the trade balance remaining in equilibrium9. An autonomous increase in S from a condition of equilibrium in national income and in the trade balance results in the nation's income:a. rising and its trade balance turning into surplus*b. falling and its trade balance turning into surplusc. falling and its trade balance turning into deficitd. rising and its trade balance turning into deficit10. The foreign trade multiplier of nation 1 is largest:a. when there are no foreign repercussionsb. with foreign repercussions for an autonomous increase in nation 1's X that replace domestic production in nation 2*c. with foreign repercussions for an autonomous increase in I in nation 1d. with foreign repercussions for an autonomous increase in I in nation 211.

In the real world, the automatic income, price, and interest adjustment mechanisms, ifallowed to operate, are likely to:a. reinforce each other but still result in incomplete adjustment*b. reinforce each other and result in complete adjustmentc. work at cross purposes from each other and result in incomplete adjustmentd. work at cross purposes from each other and result in perverse adjustment15. A benefit of automatic adjustment mechanisms is that they:a. avoid the possibility of policy mistakesb. avoid the time lags associated with adjustment policiesc. begin to operate as soon as balance of payments disequilibria develop*d. all of the above(6921029.doc) 17-14 Dominick Salvatore。

In the first lecture, I would present Sections 1, 2, and 3. These are short s sections and set the stage for the crucial law of comparative advantage.2.In the second lecture of Chapter 2, I would concentrate on Section 4 and carefullyexplain the law of comparative advantage using simple numerical examples as in the text. The crucial parts here are 4b (which explains the law) and 4d (which establishes the link between trade theory and international finance). I find that the numerical explanations before the graphical analysis really helps the student to truly understand the law. The simple lawyer-secretary example should also render the law more immediately relevant to the student. I would also assign Problems 1-6.3.In the third lecture, I would cover Sections 2.5 and 2.6a. I would pay particularattention to Sections 2.5c, 2.5d, and 2.6, which are the heart of the chapter.4.In the fourth lecture, I would cover the remainder of the chapter. The crucial sectionhere is 2.6b and the most difficult concept to explain is the shape of the combined supply curve for wheat and cloth. The appendixes could be made optional for the more enterprising students in the class. I would also assign Problems 7-13. Answer to Problems1.In case A, the United States has an absolute advantage in wheat and the UnitedKingdom in cloth.In case B, the United States has an absolute advantage (so that the United Kingdom has an absolute disadvantage) in both commodities.In case C, the United States has an absolute advantage in wheat but has neither an absolute advantage nor disadvantage in cloth.In case D, the United States has an absolute advantage over the United Kingdom in both commodities.2.In case A, the United States has a comparative advantage in wheat and the UnitedKingdom in cloth.In case B, the United States has a comparative advantage in wheat and the United Kingdom in cloth.In case C, the United States has a comparative advantage in wheat and the United Kingdom in cloth.In case D, the United States and the United Kingdom have a comparative advantage in neither commodities.3.In case A, trade is possible based on absolute advantage.In case B, trade is possible based on comparative advantage.In case C, trade is possible based on comparative advantage.In case D, no trade is possible because the absolute advantage that the United States has over the United Kingdom is the same in both commodities.4. a) The United States gains 1C.b) The United Kingdom gains 4C.c) 3C < 4W < 8C.d) The United States would gain 3C while the United Kingdom would gain 2C.5)a) The cost in terms of labor content of producing wheat is 1/4 in the United States aand 1 in the United Kingdom, while the cost in terms of labor content ofproducing cloth is 1/3 in the United States and 1/2 in the United Kingdom.b) In the United States, Pw=$1.50 and Pc=$2.00.c) In the United Kingdom, Pw=£1.00 and Pc=£0.50.6)a) With the exchange rate of £1=$2, Pw=2.00 and Pc=$1.00 in the UnitedKingdom, so that the United States would be able to export wheat to the United Kingdom and the United Kingdom would be able to export cloth to the United States.b) With the exchange rate of £1=$4, Pw=$4.00 and Pc=$2.00 in the UnitedKingdom, so that the United States would be able to export wheat to the UnitedKingdom, but the United Kingdom would be unable to export any cloth to theUnited States.c) With £1=$1, Pw=$1.00 and Pc=$0.50 in the United Kingdom, so that the UnitedKingdom would be able to export both commodities to the United States.d) $1.50 < £1.00 < $4.00.7. a) See Figure 1.b) In the United States Pw/Pc=3/4, while in the United Kingdom, Pw/Pc=2.c) In the United States Pc/Pw=4/3, while in the United Kingdom Pc/Pw=1/2.8. See Figure 2.The autarky points are A and A' in the United States and the United Kingdom, respectively. The points of production with trade are B and B' in the United States and the United Kingdom, respectively. The points of consumption are E and E' in the United States and the United Kingdom, respectively. The gains from trade are shown by E > A for the U.S. and E' > A' for the U.K.9. a) If D W(US+UK)shifted up in Figure 2.3, the equilibrium relative commodity priceof wheat would also rise by 1/3 to P W/P C=4/3. Since the higher D W(US+UK)would still intersect the vertical portion of the S W(US+UK)curve, the United States would continue to specialize completely in the production of wheat and produce 180W, while the United kingdom would continue to specialize completely in the production of cloth and produce 120C.b) Since the equilibrium relative commodity price of cloth is the inverse of therelative commodity price of wheat, if the latter rises to 4/3, then the former falls to ¾.. This means that D C(UK+US) shifts down by 1/3 in the right panel of Figure 2.3.10.If D W(US+UK)intersected S W(US+UK)at P W/P C=2/3 and 120W in the left panel ofFigure 2.3, this would mean that the United States would not be specializing completely in the production of wheat.The United Kingdom, on the other hand, would be specializing completely in the production of cloth and exchanging 20C for 30W with the United States. Since the United Kingdom trades at U.S. the pre-trade relative commodity price of P W/P C=2/3 in the United States, the United Kingdom receives all of the gains from trade.11. See Figure 3 on page 15 and the discussion in the last paragraph of Section 2.6b inthe text.12. a) The Ricardian model was tested empirically by showing the positive correlationbetween relative productivities and the ratio of U.S.to U.K. exports to third countries and by the negative correlation between relative unit labor costs and relative exportsb) The Ricardian trade model was confirmed by the positive relationship foundbetween the relative labor productivity and the ratio of U.S. to U.K. exports to third countries, as well as by the negative relationship between relative unit labor costs and relative exports.c) Even though the Ricardian model was more or less empirically confirmed westill need other models because the former assumes rather than explains comparative advantage (i.e, it does not explain the reason for the different labor productivities in different nations) and cannot say much regarding the effect of international trade on the earnings of factors of production.d) The United States has a comparative disadvantage in the production of textiles.Restricting textile imports would keep U.S. workers from eventually moving into industries in which the United States has a comparative advantage and in which wages are higher.Answer to Problem in Appendix 2The numbers in the following table refer to the cost or price of commodities X, Y, and Z in nations A, B, and C in terms of the same currency. Thus, nation A exports commodity X to nations B and C; nation B exports commodity Y to nations A and C; nation C exports commodity Z to nations A and B.Multiple-Choice Questions1.

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 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. A production frontier that is concave from the origin indicates that thenation incursincreasing opportunity costs in the production of:a. commodity X onlyb. commodity Y only*c. both commoditiesd. neither commodity2. The marginal rate of transformation (MRT) of X for Y refers to:a. the amount of Y that a nation must give up to produce each additional unit of Xb. the opportunity cost of Xc. the absolute slope of the production frontier at the point of production*d. all of the above3. Which of the following is not a reason for increasing opportunity costs:*a. technology differs among nationsb. factors of production are not homogeneousc. factors of production are not used in the same fixed proportion in the production of all commoditiesd. for the nation to produce more of a commodity, it must use resources that are less and less suited in the production of the commodity4. Community indifference curves:a. are negatively slopedb. are convex to the originc. should not cross*d. all of the above5. The marginal rate of substitution (MRS) of X for Y in consumption refers to the:a. amount of X that a nation must give up for one extra unit of Y and still remain on the same indifference curve*b. amount of Y that a nation must give up for one extra unit of X and still remain on the same indifference curvec. amount of X that a nation must give up for one extra unit of Y to reach a higher indifference curved. amount of Y that a nation must give up for one extra unit of X to reach a higher indifference curve6. Which of the following statements is true with respect to the MRS of X for Y?a. It is given by the absolute slope of the indifference curveb. declines as the nation moves down an indifference curvec. rises as the nation moves up an indifference curve*d. all of the above7. Which of the following statements about community indifference curves is true?a. 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. The gains from exchange with respect to the gains fromspecialization are always:a. greaterb. smallerc. equal*d. we cannot say without additional information15. Mutually beneficial trade cannot occur if production frontiers are:a. equal but tastes are notb. different but tastes are the samec. different and tastes are also different*d. the same and tastes are also the same.。

曼昆宏观经济经济学第九版英文原版答案完整版曼昆宏观经济经济学第九版英文原版答案集团标准化办公室：[VV986T-J682P28-JP266L8-68PNN]A n s w e r s t o T e x t b o o k Q u e s t i o n s a n d P r o b l e m sCHAPTER 7Unemployment and the Labor MarketQuestions for Review1. The rates of job separation and job finding determine the naturalrate of unemployment. The rate of job separation is the fraction of people who lose their job each month. The higher the rate of jobseparation, the higher the natural rate of unemployment. The rate of job finding is the fraction of unemployed people who find a job each month. The higher the rate of job finding, the lower the natural rate of unemployment.2. Frictional unemployment is the unemployment caused by the time ittakes to match workers and jobs. Finding an appropriate job takes time because the flow of information about job candidates and job vacancies is not instantaneous. Because different jobs requiredifferent skills and pay different wages, unemployed workers may not accept the first job offer they receive.In contrast, structural unemployment is the unemployment resulting from wage rigidity and job rationing. These workers are unemployed not because they are actively searching for a job that best suits their skills (as in the case of frictional unemployment), but because at the prevailing real wage thequantity of labor supplied exceeds the quantity of labor demanded. If the wage does not adjust to clear the labor market, then these workers must wait for jobs to become available. Structural unemployment thus arises because firms fail to reduce wages despite an excess supply of labor.3. The real wage may remain above the level that equilibrates laborsupply and labor demand because of minimum wage laws, the monopoly power of unions, and efficiency wages.Minimum-wage laws cause wage rigidity when they prevent wages from falling to equilibrium levels. Although most workers are paid a wage above the minimum level, for some workers, especially the unskilled and inexperienced, the minimum wage raises their wage above theequilibrium level. It therefore reduces the quantity of their labor that firms demand, and creates an excess supply of workers, which increases unemployment.The monopoly power of unions causes wage rigidity because the wages of unionized workers are determined not by the equilibrium of supply and demand but by collective bargaining between union leaders and firm management. The wage agreement often raises the wage abovethe equilibrium level and allows the firm to decide how many workers to employ. These high wages cause firms to hire fewer workers than at the market-clearing wage, so structural unemployment increases.Efficiency-wage theories suggest that high wages make workers more productive. The influence of wages on worker efficiency may explain why firms do not cut wages despite an excess supply of labor. Even though a wage reduction decreasesthe firm’s wage bill, it may also lower worker productivity and therefore the firm’s profits.4. Depending on how one looks at the data, most unemployment can appearto be either short term or long term. Most spells of unemployment are short; that is, most of those who became unemployed find jobs quickly.On the other hand, most weeks of unemployment are attributable to the small number of long-term unemployed. By definition, the long-term unemployed do not find jobs quickly, so they appear on unemployment rolls for many weeks or months.5. Europeans work fewer hours than Americans. One explanation is thatthe higher income tax rates in Europe reduce the incentive to work. A second explanation is a larger underground economy in Europe as aresult of more people attempting to evade the high tax rates.A third explanation is the greater importance of unions in Europe and their ability to bargain for reduced work hours. A final explanation isbased on preferences, whereby Europeans value leisure more thanAmericans do, and therefore elect to work fewer hours.Problems and Applications1. a. In the example that follows, we assume that during the school yearyou look for a part-time job, and that, on average, it takes 2 weeks to find one. We also assume that the typical job lasts 1semester, or 12 weeks.b. If it takes 2 weeks to find a job, then the rate of job finding in weeks isf = (1 job/2 weeks) = 0.5 jobs/week.If the job lasts for 12 weeks, then the rate of job separation in weeks iss = (1 job/12 weeks) = 0.083 jobs/week.c. From the text, we know that the formula for the natural rate of unemployment is(U/L) = [s/(s + f )],where U is the number of people unemployed, and L is the number of people in the labor force.Plugging in the values for f and s that were calculated in part (b), we find(U/L) = [0.083/(0.083 + 0.5)] = 0.14.Thus, if on average it takes 2 weeks to find a job that lasts 12 weeks, the natural rate of unemployment for this population ofcollege students seeking part-time employment is 14 percent.2. Call the number of residents of the dorm who are involved I, thenumber who are uninvolved U, and the total number of students T = I + U. In steady state the total number of involved students is constant.For this to happen we need the number of newly uninvolved students,(0.10)I, to be equal to the number of students who just becameinvolved, (0.05)U. Following a few substitutions:(0.05)U = (0.10)I= (0.10)(T – U),soWe find that two-thirds of the students are uninvolved.3. To show that the unemployment rate evolves over time to thesteady-state rate, let’s begin by defining how the number of people unemployed changes over time. The change in the number of unemployed equals the number of people losing jobs (sE) minus the number finding jobs (fU). In equation form, we can express this as:U–U t= ΔU t + 1 = sE t–fU t.t + 1Recall from the text that L = E t + U t, or E t = L –U t, where L is the total labor force (we will assume that L is constant). Substituting for E t in the above equation, we findΔU t + 1 = s(L –U t) –fU t.Dividing by L, we get an expression for the change in the unemployment rate from t to t + 1:ΔU t + 1/L = (U t + 1/L) –(U t/L) = Δ[U/L]t + 1 = s(1 –U t/L) –fU t/L.Rearranging terms on the right side of the equation above, we end up with line 1 below. Now take line 1 below, multiply the right side by (s + f)/(s + f) and rearrange terms to end up with line 2 below:Δ[U/L]t + 1= s – (s + f)U t/L= (s + f)[s/(s + f) – U/L].tThe first point to note about this equation is that in steady state, when the unemployment rate equals its natural rate, the left-handside of this expression equals zero. This tells us that, as we found in the text, the natural rate of unemployment (U/L)n equals s/(s + f).We can now rewrite the above expression, substituting (U/L)n for s/(s + f), to get an equation that is easier to interpret: Δ[U/L]t + 1 = (s + f)[(U/L)n–U t/L].This expression shows the following:If U t/L > (U/L)n (that is, the unemployment rate is above its natural rate), then Δ[U/L]t + 1 is negative: the unemployment rate falls.If U t/L < (U/L)n (that is, the unemployment rate is below its natural rate), then Δ[U/L]t + 1 is positive: the unemployment raterises.This process continues until the unemployment rate U/L reaches the steady-state rate (U/L)n.4. Consider the formula for the natural rate of unemployment,If the new law lowers the chance of separation s, but has no effect on the rate of job finding f, then the natural rate of unemployment falls.For several reasons, however, the new law might tend to reduce f.First, raising the cost of firing might make firms more careful about hiring workers, since firms have a harder time firing workers who turn out to be a poor match. Second, if job searchers think that the new legislation will lead them to spend a longer period of time on a particular job, then they might weigh morecarefully whether or not to take that job. If the reduction in f is large enough, then the new policy may even increase the natural rate of unemployment.5. a. The demand for labor is determined by the amount of labor that aprofit-maximizing firm wants to hire at a given real wage. The profit-maximizing condition is that the firm hire labor until the marginal product of labor equals the real wage,The marginal product of labor is found by differentiating the production function with respect to labor (see Chapter 3 for more discussion),In order to solve for labor demand, we set the MPL equal to the real wage and solve for L:Notice that this expression has the intuitively desirable feature that increases in the real wage reduce the demand for labor.b. We assume that the 27,000 units of capital and the 1,000 units oflabor are supplied inelastically (i.e., they will work at anyprice). In this case we know that all 1,000 units of labor and 27,000 units of capital will be used in equilibrium, so we can substitute these values into the above labor demand function and.solve for WPIn equilibrium, employment will be 1,000, and multiplying this by10 we find that the workers earn 10,000 units of output. The totaloutput is given by the production function:Y=5Y13Y23Y=5(27,00013)(1,00023)Y=15,000.Notice that workers get two-thirds of output, which is consistent with what we know about the Cobb–Douglas production function from Chapter 3.c. The real wage is now equal to 11 (10% above the equilibrium levelof 10).Firms will use their labor demand function to decide how manyworkers to hire at the given real wage of 11 and capital stock of 27,000:So 751 workers will be hired for a total compensation of 8,261units of output. To find the new level of output, plug the new value for labor and the value for capital into the production function and you will find Y = 12,393.d. The policy redistributes output from the 249 workers who becomeinvoluntarily unemployed to the 751 workers who get paid more than before. The lucky workers benefit less than the losers lose as the total compensation to the working class falls from 10,000 to 8,261 units of output.e. This problem does focus on the analysis of two effects of theminimum-wage laws: they raise the wage for some workers whiledownward-sloping labor demand reduces the total numberof jobs.Note, however, that if labor demand is less elastic than in this example, then the loss of employment may be smaller, and thechange in worker income might be positive.6. a. The labor demand curve is given by the marginal product of laborschedule faced by firms. If a country experiences a reduction inproductivity, then the labor demand curve shifts to the left as in Figure 7-1. If labor becomes less productive, then at any givenreal wage, firms demand less labor.b. If the labor market is always in equilibrium, then, assuming afixed labor supply, an adverse productivity shock causes adecrease in the real wage but has no effect on employment orunemployment, as in Figure 7-2.c. If unions constrain real wages to remain unaltered, then asillustrated in Figure 7-3, employmentfalls to L1 and unemployment equals L –L1.This example shows that the effect of a productivity shock on aneconomy depends on the role of unions and the response of collective bargaining to such a change.7. a. If workers are free to move between sectors, then the wage in each sector will be equal. If thewages were not equal then workers would have an incentive to move to the sector with the higherwage and this would cause the higher wage to fall, and the lower wage to rise until they wereequal.b. Since there are 100 workers in total, L S = 100 – L M. We cansubstitute this expression into the labor demand for services equation, and call the wage w since it is the same in bothsectors:L S = 100 – LM= 100 – 4wLM= 4w.Now set this equal to the labor demand for manufacturing equation and solve for w:4w = 200 – 6ww = $20.Substitute the wage into the two labor demand equations to find L M is 80 and L S is 20.c. If the wage in manufacturing is equal to $25 then L M is equal to 50.d. There are now 50 workers employed in the service sector and the wage w S is equal to $12.50.e. The wage in manufacturing will remain at $25 and employment will remain at 50. If thereservation wage for the service sector is $15 then employment in the service sector will be 40. Therefore, 10 people are unemployed and the unemployment rate is 10 percent.8. Real wages have risen over time in both the United Statesand Europe,increasing the reward for working (the substitution effect) but also making people richer, so they want to “buy” more leisure (theincome effect). If the income effect dominates, then people want to work less as real wages go up. This could explain the Europeanexperience, in which hours worked per employed person have fallen over time. If the income and substitution effects approximatelycancel, then this could explain the U.S. experience, in which hours worked per person have stayed about constant. Economists do not have good theories for why tastes might differ, so they disagree onwhether it is reasonable to think that Europeans have a larger income effect than do Americans.9. The vacant office space problem is similar to the unemploymentproblem; we can apply the same concepts we used in analyzingunemployed labor to analyze why vacant office space exists. There isa rate of office separation: firms that occupy offices leave, eitherto move to different offices or because they go out of business.There is a rate of office finding: firms that need office space (either to start up or expand) find empty offices. It takes time to match firms with available space. Different types of firms require spaces with different attributes depending on what theirspecific needs are. Also, because demand for different goods fluctuates, there are “sectoral shifts”—changes in the composition of demand among industries and regions that affect the profitability and office needs of different firms.。

I would also clearly explain the importance ofstrategic trade and industrial policy and the political economy of who getsprotected.5.I would cover section 5 in lecture 4, which examines strategic trade andindustrial policies policies with game theory. This is not difficult and thestudents will find it very interesting.6.Sections 6 and 7 can be covered in lecture 5. Here I would stress the UruguayRound and the outstanding international trade problems.Answer to Problems:1. Nations restrict trade either in response to lobbying by the producers of acommodity in which the nation has a comparative disadvantage or to gain astrategic advantage in relation to other nations. The first leads to a welfare loss for he nation as a whole. The second is very difficult to achieve.2. The partial equilibrium effects of the import quota are:P x=$1.50; consumption is 45X, of which 15X are produced domestically;by auctioning off import licenses, the revenue effect would be $15.3. The partial equilibrium effects of the import quota are:P x=$2.50; consumption is 40X, of which 10X are produced domestically;the revenue effect is $45.4. The partial equilibrium effects of the quota are:P x=$2; domestic production and consumption are 50X; The revenue is zero.5. The partial equilibrium effects of the quota are:P x=$1; consumption is 70X, production is 30X, and revenue is zero.6. The partial equilibrium effects of a negotiated export quota of 30X are:P x=$4; domestic production is 40X, of which 10X are consumed at home.7.An export tariff or quota, as an import tariff or quota, affects the price of thecommodity and domestic consumption and production. But the effects are theopposite.8. See Figure 1.The equilibrium price of the commodity is P x=OC and the equilibrium quantity is Q x=OB in Figure 1.9.If the supply curve of the commodity in Figure 1 referred to a cartel ofexporters acting as a monopolist, P x=OF and Q x=OA (see Figure 1).10. P x is higher and Q x smaller when exporters behave as a monopolist.11. a) The monopolist should charge P1=$4 in the domestic market and P2=$3 inFigure 9-5 in Appendix A9.2.b) This represents the best, or optimal distribution of sales between the twomarkets because any other distribution of sales in the two markets gives lessrevenue.12. See Figure 2. To the left of point A, the domestic firm faces higher long-run average costs of production (LAC D) than the foreign firm (LAC F). To theright of point A the opposite is the case.13.a) If the entries in the top left-hand corner of Table 9-5 were changed to +10,+10, then both Boeing and Airbus would produce the aircraft without anysubsidy, and so no strategic trade and industrial policy would be needed in theU.S. or Europe.b)If the entries in the top left-hand corner of Table 9-5 were changed to +5, +0,then both Boeing and Airbus would produce the aircraft without any subsidy, and so no strategic trade and industrial policy would be needed in the U.S. or Europe.*Note that even though Airbus only breaks even, in economics we includea normal return on investment as part of costs. Thus, Airbus wouldremain in business because it would earn a normal return on investment.c)If the entries in the top left-hand corner of Table 9-5 were changed to +5, -10,then both Boeing produces and Airbus does not produce without any subsidy.With a subsidy of at least $10 million per year, however, Airbus would enterthe market and lead to a loss of $100 million for Boeing unless the U.S.government would provide a subsidy of at least $5 million per year to Boeing.14. The answer to part (a) and (b) are presented in Appendix A9.3.App. 1. See Figure 3 on page 90.App. 2.

This is one of the most important and challenging of the chapters. Sections 1-2and 6-7 are core sections and should be covered in any international economicscourse. Sections 3-5 introduce the IS-LM-BP model and may be skipped ifintermediate macroeconomics is not a requirement for the course. This is up to the Instructor, however.2. In the first lecture, I would cover sections 1 and 2 and assign problems 1-3. Themost important and difficult part here is the Swan diagram. If students are toknow anything about economic policies to correct internal and externalimbalances, this is it.3. Sections 3-5 require two classes to be covered adequately if students hadintermediate macroeconomics. Otherwise, it would take three classes, or they can be skipped. If sections 3-5 are covered, I would assign problems 4-11 and go over some of these in class to make sure that students fully understand the model and the policies that can be used to correctinternal and external imbalances.4. I would cover section 6 in the next class and assign problems 12-14. The mostimportant aspect of this section is the explicit recognition of price stability as thethird important objective of nations and the problems that this creates with thepolicies at hand to achieve internal and external balance completely. I would also cover Case Studies 18.1-18-3.5. I would leave section 7 for students to cover by themselves. The section isimportant but mostly descriptive and students to read it on their own and bringquestions to class.Answer to Problems:1.

Point Change in D Change in RC2 increase noneC5 none revalueC8 decrease noneC11 none devalue3. Point Change in D Change in RC3 increase revalueC6 decrease revalueC9 decrease devalueC12 increase devalue4. a. The nation faces a surplus at Y E=1,000 because P is below point E.b. At Y E=1,000 and with a MPM=0.15, the nation faces a surplus of(200)(0.15)=30.5. The nation of problem 4 can reach full employment with external balance with theexpansionary fiscal policy that shifts IS upward until it crosses the BP line atpoint F and the tight monetary policy that shifts LM upward until it also crossesthe BP line at point F.6. The nation requires the expansionary fiscal that shifts the IS curve up until itcrosses the BP curve at point F and the tight monetary policy that shifts up theLM curve until it crosses the BP curve at point F.See Figure 1.7. If the full-employment level of national income is YE=1,000, the nation requiresthe expansionary fiscal policy that shifts the IS curve up until it crosses the BPcurve at point B' and the tight monetary policy that shifts up the LM curve until it crosses the BP curve at point B'.See Figure 2.8. a. If the BP curve were flatter than the LM curve, the nation would require theexpansionary fiscal policy that shifts the IS curve up until it crosses the PB curve at point F and the easy monetary policy that shifts down the LM curve until itcrosses the BP curve at point F.See Figure 3.b. When the BP curve is flatter than the LM curve, the nation requires an easy ratherthan a tight monetary policy to achieve internal and external balancesimultaneously.9. With perfectly elastic international capital flows, the BP line would be horizontaland monetary policy would be completely ineffective. The nation could reachinternal and external balance with the appropriate expansionary fiscal policy only.10. Starting from point E in Figure 18-8 in the text, the nation could use the fiscalpolicy that shifts the IS curve to IS', intersecting the LM curve at point Z (seeFigure 4 on the next page). Since point Z is to the right of the BP curve, the nation will have a deficit in its balance of payments. With flexible exchange rates, thenation's currency depreciates and so the BP curve shifts to the right. This inducesa leftward shift in the LM curve to LM', such that curve IS" and LM' intersect onthe BP curve at point E'. Since at point E' the nation still faces unemployment, the nation would need to apply additional doses of expansionary fiscal policy until all three markets are in equilibrium at the full-employment level of national income of YF = 1500.11. Starting from point E in Figure 18-8 in the text, the nation could use the fiscalpolicy that shifts the IS curve to IS' (see Figure 5 on the next page), intersectingthe LM curve at point Z. Since point Z is now to the left of the BP curve, thenation will have a surplus in its balance of payments. With flexible exchangerates, the nation's currency appreciates and so the BP curve shifts to the left. This induces a leftward shift in the IS curve to IS" and a rightward shift in the LMcurve to LM', such that curve IS" and LM' intersect on the BP curve at point E'.Since at point E' the nation still faces unemployment, the nation would need toapply additional doses of expansionary fiscal policy until all three markets are inequilibrium at the full-employment level of national income of YF = 1500.12.

Draw a dashed rectangle with corners (Y=1125, i=10%) on the IS' line,(Y=1125, leakages=500) on theS(Y)+M(Y) line, (injections=500, leakages=500) on the 45 degree line, and(injections=500, i = 10%) on the I(i)+X+G line. S increases by(?Y)(MPS)=(125)(0.25, from section 17.3c) = 31.25, M increases by(?Y)(MPM)=(125)(0.15)=18.75 for a total increase in leakages of 50 equal to theincrease in injections of G=50.App. 2a Draw in panel III of Figure 18-12 the MS' line 100 units to the left of MS, in panel IV the ML' line 100 units to the right of ML, and in panel I the LM' line 500units to the right of LM (the MT line in panel II remains unchanged). Draw adashed rectangle with corners (Y=1250, i=8%) on the LM' line, (Y=1250,MT=500) on the MT line, (ML=400, MT=500) on the MS' line, and (ML=400,i=8%) on the ML' line.App. 2b Xerox Figure 18-12 and draw in panel II the MT' line 500 units to the left of MT, and in panel I the LM" line 500 units to the left of LM (the MS and ML linesremain unchanged).

The fallin Y E induces a total fall in S and M equal to the fall in G*(graphically, this can be shown by the opposite changes from those described inApp. 1 above).App. 4b The reduction in MS* causes i to rise and ML and MT to fall. These effects are generally the opposite of those described in App. 2a above.App. 4c An appreciation or revaluation causes X to fall and M to rise (see equation 18A-1), MT to fall (see equation 18A-2), and TB to deteriorate (see equation 18A-3).Multiple-choice Questions:1.

difficult to understand. therefore, i would pay special care in presenting the material in section 2a.i would also assign problems 1 to 8. 2.in the second lecture, i would cover section 2b and go over problems 1-8.i would present sections 3 and 4 in the third lecture, and stress the meaning and measurement of balance of payments deficitsand surpluses.sections 5 and 6 (which are mostly descriptiveand not difficult) could be left for studentsto do on their own so that the chapter could still be covered in three lectures.1. a.the u.s. debits its current account by $500 (for the merchandise imports) and credits capital by the same amount (for the increase in foreign assets in the u.s.).the u.s. credits capital by $500 (the drawing down of its bank balances in london, a capital inflow) and debits capital by an equal amount (to balance the capital credit that the u.s. importer received when the u.k. exporter accepted to be paid in three months).the u.s. is left with a $500 debit in its current account and a net credit balance of $500 in its capital account.2. a).the u.s. debits unilateral transfers by $100 and credits capital by the same amount.b).the u.s. credits its current account by $100 and debits capital by the same amount.c).the debit of $100 in unilateral transfers and the credit of $100 in current account.3. a).the same as 2a.the net result is the

by $400 (for the capital outflow for the repayment of the repayment of the principal to the foreign investors by the u.s. borrower), and then credits its capital account by $440 (the increase in foreign holdings of u.s. assets, a credit).8. a). the u.s. credits its capital account by $800 and debits its official reserves account by the same amount.b). the official settlements balance of the u.s. will improve (i.e., the u.s. deficit will fall or its surplus will rise) by $800.where values are in billions of dollars and a negative balance represents a deficit while apositive balance a surplus in the balance of payments. b. because until 1972, we had a fixed exchange rate system, but from 1973 we had a managed floating exchange rate system. under the latter, the balance of payments only measures the amount of official intervention in foreign exchange markets. 9.see the july issue of the survey of current business for the most recent year.10.see the july issue of the survey of

international monetary fund method is in the way they deal with international capital movements. the united states records international capital movements as increases in u.s.-owned assets abroad and foreign-owned assets in the united states, subdivided into government and private. the international monetary fund includes international capital flows into a financial account, which is subdivided into direct investments, portfolio investments assets and liabilities, and other investment assets and liabilities.2. see the table in april and october issue of the imfs world economic outlook for

and 7 can be covered in lecture 5. here i would stress the uruguayround and the outstanding international trade problems.1.nations restrict trade either in response to lobbying by the producers of acommodity in which the nation has a comparative disadvantage or to gain astrategic advantage in relation to other nations. the first leads to a welfare loss for he nation as a whole. the second is very difficult to achieve.2.the partial equilibrium effects of the import quota are:px=$1.50; consumption is 45x, of which 15x are produced domestically;by auctioning off import licenses, the revenue effect would be $15.3.the partial equilibrium effects of the import quota are:px=$2.50; consumption is 40x, of which 10x are produced domestically;the revenue effect is $45.4.the partial equilibrium effects of the quota are:px=$2; domestic production and consumption are 50x; the revenue is zero.5.the partial equilibrium effects of the quota are:px=$1; consumption is 70x, production is 30x, and revenue is zero.6.the partial equilibrium effects of a negotiated export quota of 30x are:7.8.px=$4; domestic production is 40x, of which 10x are consumed at home. an export tariff or quota, as an import tariff or quota, affects the price of the commodity and domestic consumption and production. but the effects are the opposite. see figure 1. the equilibrium price of the commodity is px=oc and the equilibrium quantityis qx=ob in figure 1.9.10.11.if the supply curve of the commodity in figure 1 referred to a cartel of exporters acting as a monopolist, px=of and qx=oa (see figure 1). px is higher and qx smaller when exporters behave as a monopolist. a) the monopolist should chargep1=$4 in the domestic market and p2=$3 in figure 9-5 in appendix a9.2.b) this represents the best, or optimal distribution of sales between the twomarkets because any other distribution of sales in the two markets gives lessrevenue.12. see figure 2. to the left of point a, the domestic firm faces higher long-run average costs of production (lacd) than the foreign firm (lacf). to the right of point a the opposite is the case.13. a) if the entries in the top left-hand corner of table 9-5 were changed to +10,+10, then both boeing and airbus would produce the aircraft without anysubsidy, and so no strategic trade and industrial policy would be needed in the u.s. or europe.b) if the entries in the top left-hand corner of table 9-5 were changed to +5, +0, then both boeing and airbus would produce the aircraft without any subsidy, and so no strategic trade and industrial policy would be needed in the u.s. or europe. *note that even though airbus only breaks even, in economics we includea normal return on investment as part of costs. thus, airbus wouldremain in business because it would earn a normal return on investment.c) if the entries in the top left-hand corner of table 9-5 were changed to +5, -10,then both boeing produces and airbus does not produce without any subsidy.with a subsidy of at least $10 million per year, however, airbus would enterthe market and lead to a loss of $100 million for boeing unless the u.s.government would provide a subsidy of at least $5 million per year to boeing.14.the answer to part (a) and (b) are presented in appendixa9.3.app. 1. see figure 3 on page 90.app. 3. by imposing a 100% tax on the production of commodity x and giving it as a subsidy to producers of commodity y.【篇三：国际经济学第九版英文课后答案第18单元】>open-economy macroeconomics: adjustment policiesoutline*18.1 introductioncase study 18-1: government, private sector, and

are core sections and should be covered in any international economics course. sections 3-5 introduce the is-lm-bp model and may be skipped ifintermediate macroeconomics is not a requirement for the course. this is up to the instructor, however.2. in the first lecture, i would cover sections 1 and 2 and assign problems 1-3. the most important and difficult part hereis the swan diagram. if students are to know anything about economic policies to correct internal and externalimbalances, this is it.3. sections 3-5 require two classes to be covered adequately if students hadintermediate macroeconomics. otherwise, it would take three classes, or they can be skipped. if sections 3-5 are covered, i would assign problems 4-11 and go over some of these in class to make sure that students fully understand the model and the policies that can be used to correctinternal and external imbalances.4. i would cover section 6 in the next class and assign problems 12-14. the most important aspect of this section is the explicit recognition of price stability as the third important objective of nations and the problems that this creates with the policies at hand to achieve internal and external balance completely. i would also cover case studies 18.1-18-3.5. i would leave section 7 for students to cover by themselves. the section isimportant but mostly descriptive and students to

point f and the tight monetary policy that shifts up the lm curve until it crosses the bp curve at point f.see figure 1.7. if the full-employment level of national income is ye=1,000, the nation requires the expansionary fiscal policy that shifts the is curve up until it crosses the bp curve at point b and the tight monetary policy that shifts up the lm curve until it crosses the bp curve at point b.see figure 2.8. a. if the bp curve were flatter than the lm curve, the nation would require theexpansionary fiscal policy that shifts the is curve up until it crosses the pb curve at point f and the easy monetary policy that shifts down the lm curve until it crosses the bp curve at point f.see figure 3.b.9.when the bp curve is flatter than the lm curve, the nation requires an easy rather than a tight monetary policy to achieve internal and external balance simultaneously. with perfectly elastic international capital flows, the bp line would be horizontal and monetary policy would be completely ineffective. the nation could reach internal and external balance with the appropriate expansionary fiscal policy only.。

As the first chapter of the book, the general aim here is simply to define the fieldof study of international economics and its importance in today's interdependent world.The material in this chapter can be covered in two classes. I would utilize oneclass to cover Sections 1 to 4 and the second class to cover Sections 5 to 8. Iwould spend most of the second class on Section 6 on the major currentinternational economic challenges facing the United States and the world todayand to show how international economics can suggest ways to solve them. Thisshould greatly enhance students' motivation.Answer to Problems1. a) International economic problems reported in our daily newspapers are likely toinclude:•trade controversies between the United States, Europe, Japan, and China;•great volatility of exchange rates;•Increasing international competition from China and fear of job losses in the United States and other advanced countries.•structural unemployment and slow growth in Europe, and stagnation in Japan;•financial crises in emerging market economies;•restructuring problems of transition economies;•deep poverty in many developing nations in the world.b) Can result in trade restrictions or even a trade war, which reduce the volumeand the gains from trade;•discourage foreign trade and investments, and thus reduce the benefits from trade;•Can result in trade restrictions or even a trade war, which reduce the volume and the gains from trade;•reduces European and Japanese imports and the volume and the benefits from trade;•financial crises in emerging market economies could spread to the United States;•can lead to political instability, which will adversely affect the United States;•can lead to political instability in these countries - which also adversely affect the United States.c) Can result in your paying higher prices for imported products;•lead to great fluctuations in the price of imported products and cost of foreign travel;•Can lead higher prices for imported products and increases the chances that you will have to change jobs;•can lead you to support demands for trade protection in the United States;•can reduce the value of your investments (such as a stocks) in the United States;•can lead to your paying higher taxes for the United States to respond to these threats;•can result in your paying higher taxes to help these nations.2. a) Five industrial nations not mentioned are: Italy, France, Canada, Austria, andIreland.b) See Table 1A.c) Smaller nations, such as Ireland and Austria, are more interdependent than thelarger ones. Note that interdependence was measured by the percentage of thevalue of imports and exports (line 98c and 90c, respectively in IFS) to GDP (line99b).Table 1AEconomic Interdependence asMeasured by Imports and Exports*Source: International Financial Statistics(Washington, D.C., IMF, March 2006).3. a) Five developing nations not mentioned in the text are: Brazil, Pakistan,Colombia, Nepal, and Tunisia.b) See Table 1B.c) In general, the smaller the nation, the greater is its economic interdependence.Note that interdependence was measured by the percentage of the value ofimports and exports (line 98c and 90c, respectively in IFS) to GDP (line 99b).Table 1BEconomic Interdependence asMeasured by Imports and Exports*Source: International Financial Statistics(Washington, D.C., IMF, March 2006).4. Trade between the United States and Brazil is much larger than trade between theUnited States and Argentina. Since Brazil is larger and closer than Argentina, this trade does follow the predictions of the gravity model.5. a) Mankiw’s Economics (4th., 2007) includes the following microeconomicstopics:•The market forces of demand and supply;•elasticity and its application;•the theory of consumer choice;•consumers, producers, and the efficiency of markets;•the costs of production;•firms in competitive markets;•monopoly;•oligopoly;•monopolistic competition;•markets for the factors of production;•the demand for resources;b) Just as the microeconomics parts of your principles text deal with individualconsumers and firms, and with the price of individual commodities and factors of production, so do Parts One and Two of this text deal with production andconsumption of individual nations with nations with and without trade, and withthe relative price of individual commodities and factors of production.c) Mankiw’s Economi cs (4th., 2007) includes the following microeconomics topics:measuring a nation’s income and the cost of living;•production and growth;•savings investment and the financial system;•unemployment and its natural rate;•the monetary system, growth and inflation;•money growth and inflation;•open-economy macroeconomics: basic concepts;• a macroeconomic theory of the open economy;•aggregate demand and aggregate supply;•the influence of monetary and fiscal policy on aggregate demand;•the short-run trade off between inflation and unemployment•five debates over macroeconomic policy.d) Just as the macroeconomics parts of your principles text deal with the aggregatelevel of savings, consumption, investment, and national income, the general price level, and monetary and fiscal policies, so do Parts Three and Four of this textdeal with the aggregate amount of imports, exports, the total international flow of resources, and the policies to affect these broad aggregates.6. a) Consumer demand theory predicts than when the price of a commodity rises(cet. par.), the quantity demanded of the commodity declines.When the price of imports rises to domestic consumers, the quantity demanded of exports can be expected to decline (if everything else remains constant).7. a) A government can reduce a budget deficit by reducing governmentexpenditures and/or increasing taxes.b) A nation can reduce or eliminate a balance of payments deficit by taxingimports and/or subsidizing exports, by borrowing more abroad or lending less toother nations, as well as by reducing the level of its national income.8. a) Nations usually impose restrictions on the free international flow of goods,services, and factors. Differences in language, customs, and laws also hamperthese international flows. In addition, international flows may involve receipts and payments in different currencies, which may change in value in relation to oneanother through time. This is to be contrasted with the interregional flow ofgoods, services, and factors, which face no such restrictions as tariffs and areconducted in terms of the same currency, usually in the same language, and under basically the same set of customs and laws.b) Both international and interregional economic relations involve the overcomingof space or distance. Indeed, they both arise from the problems created bydistance. This distinguishes them from the rest of economics, which abstractsfrom space and treats the economy as a single point in space, in which production, exchange, and consumption take place.9. We can deduce that nations benefit from voluntarily engaging in internationaltrade because if they did not gain or if they lost they could avoid those losses bysimply refusing to trade. Disagreement usually arises regarding the relativedistribution of the gains from specialization in production and trade, but this does not mean that each nation does not gain from trade.10. International trade results in lower prices for consumers but harms domesticproducers of products, which compete with imports. Often those domesticproducers that stand to lose a great deal from imports band together to pressurethe government to restrict imports. Since consumers are many and unorganizedand each individually stands to lose only very little from the import restrictions,governments often give in to the demands of producers and impose some importrestrictions. These topics are discussed in detail in Chapter 9.11. A nation can subsidize exports of the commodity to other nations until it drivesthe competing nation's industry out of business, after which it can raise its priceand benefit from its newly acquired monopoly power.Some economists and politicians in the United States have accused Japan of doing just that (i.e., of engaging in strategic trade and industrial policy at the expense of U.S. industries), but this is a very complex and controversial aspect of tradepolicy and will be examined in detail in Chapter 9.12. a) When the value of the U.S. dollar falls in relation to the currencies of othernations, imports become more expensive for Americans and so they wouldpurchase a smaller quantity of imports.b) When the value of the U.S. dollar falls in relation to the currencies of othernations, U.S. exports become chapter for foreigners and so they would purchase a greater quantity of U.S. exports.Multiple-Choice Questions1.

10. See Figure 4.3. In Figure 4.3, Nation 2 is the small
nation, and we magnified the portion of the offer curve of Nation 1 (the large nation) near the origin (where Nation 1’s offer curve coincides with PA = 1/4, Nation 1’s pretrade-relative commodity price with trade). This means that Nation 2 can import a sufficiently small quantity
some import restrictions. These topics are discussed in detail in Chapter 9.
