国际经济学第十章作业 内容
第十章作业内容
1、在过去的几十年中,哪些国家收回与国际贸易?这些国家的政策有什么相同之处?它们的经验对保护幼稚工业论是支持还是反对?
2、”日本的经验表明,保护幼稚工业论比其他理论更正确。
在20世纪50年代初,日本是一个靠出口纺织品和玩具生存的穷国。
日本政府对钢铁工业和汽车工业进行了保护。
开始时,这些工业生产没有效率,成本也很高,但后来却逐渐占领了世界市场”试对上述观点进行评论。
3、一国目前以每辆8 000美元的价格进口汽车。
该国政府认为,经过一段时间后,国内生产者能够以6 000美元的成本生产汽车。
但是,在国内生产的初始尝试阶段,每辆汽车的生产成本达到10 000 美元。
a.假设每个试图生产汽车的企业都必须经过高成本的尝试生产阶段。
在什么情形下,较高的起步成本能够证明保护幼稚工业是合理的?
b.现在假设相反的情形,一旦某个企业承担了学习成本,学会了如何以6 000美元的成本生产汽车,那么其他企业就能够模仿并达到相同的水平。
试解释上述情形是怎样阻碍国内工业发展的,对幼稚工业进行保护有助于避免这种情形吗?
4、印度和墨西哥在第二次世界大战后都实行了进口替代政策,但印度更进一步,几乎所有的东西都由自己生产,而墨西哥却依赖资本品的进口。
为什么会出现这两种不同的状况呢?
5、减少进口替代工业化策略的使用,从而支持对外贸易开放的政策的原因是什么?
6、假设制造品的劳动需求=100-Lm,农业生产的劳动需求=80-La,在整个经济中有100个工人。
a.什么是均衡工资?
b.如果制造业工资被定在50,而且是充分就业,那么国民收入的损失是多少?。
国际经济学课后答案
国际经济学课后答案第一章绪论1、列举出体现当前国际经济学问题的一些重要事件,他们为什么重要?他们都是怎么影响中国与欧、美、日的经济和政治关系的?当前的国际金融危机最能体现国际经济学问题,其深刻地影响了世界各国的金融、实体经济、政治等领域,也影响了各国之间的关系因此显得尤为重要;其对中国与欧、美、日的政治和经济关系的影响为:减少中国对上述国家的出口,影响中国外汇储备,贸易摩擦加剧,经济联系加强,因而也会导致中国与上述国家在政治上的对话与合作。
2、我们如何评价一国与他国之间的相互依赖程度?我们可以通过一国的对外贸易依存度来评价该国与他国之间的相互依赖程度,也可以通过其他方式来评价比如一国政府政策的溢出效应和回震效应以及对外贸易对国民生活水平的影响。
3、国际贸易理论及国际贸易政策研究的内容是什么?为什么说他们是国际经济学的微观方面?国际贸易理论分析贸易的基础和所得,国际贸易政策考察贸易限制和新保护主义的原因和效果。
国际贸易理论和政策是国际经济学的微观方面,因为他们把国家看作基本单位,并研究单个商品的(相对)价格。
4、什么是外汇交易市场及国际收支平衡表?调节国际收支平衡意味着什么?为什么说他们是国际经济学的宏观方面?什么是宏观开放经济学及国际金融?外汇交易市场描述一国货币与他国货币交换的框架,国际收支平衡表测度了一国与外部世界交易的总收入与总支出的情况。
调节国际收支平衡意味着调节一国与外部世界交易出现的不均衡(赤字或盈余);由于国际收支平衡表涉及总收入和总支出,调节政策影响国家收入水平和价格总指数,因而他们是国际经济学的宏观方面;外汇交易及国际收支平衡调节涉及总收入和总支出,调整政策影响国家收入水平和价格总指数,这些内容被称为宏观开放经济学或国际金融。
5、浏览报刊并做下列题目:(1)找出5条有关国际经济学的新闻(2)每条新闻对中国经济的重要性或影响(3)每条新闻对你个人有何影响A (1) 国际金融危机: 影响中国整体经济,降低出口、增加失业、经济减速等(2) 美国大选:影响中美未来经济政治关系(3) 石油价格持续下跌:影响中国的能源价格及相关产业(4) 可口可乐收购汇源被商务部否决:《反垄断法》的第一次实施,加强经济法治(5) 各国政府经济刺激方案:对中国经济产生外部性效应B 以上5条新闻对个人影响为:影响个人消费水平和就业前景第二章比较优势理论1、重商主义者的贸易观点如何?他们的国家财富概念与现在有何不同?重商主义者主张政府应当竭尽所能孤立出口,不主张甚至限制商品(尤其是奢侈类消费品)。

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

Comparable figures for Japan are 20 tons of steel and 10 televisions. In this example, France has an absolute advantage in the production of steel and televisions. France has a comparative advantage in televisions.
Among the challenges confronting the international trading system are maintaining fair standards fmental quality.
The threat of international terrorism tends to slow the degree of globalization and also make it become costlier. With terrorism, companies must pay more to insure and provide security for overseas staff and property. Heightened border inspections could slow shipments of cargo, forcing companies to stock more inventory. Tighter immigration policies could reduce the liberal inflows of skilled and blue-collar laborers that permitted companies to expand while keeping wages in check. Moreover, a greater preoccupation with political risk has companies greatly narrowing their horizons when making new investments.

2.幼稚产业理论:是从动态角度提出了保护那些具有潜在优势的新兴产业的观点,但这种保护是一种暂时性的。
判别幼稚产业的标准主要有三种:其中穆勒标准强调将来的竞争优势,而巴斯塔布尔标准认为幼稚产业不仅强调将来的竞争优势,而且将来的预期收益的现值应能抵消现有的保护成本,坎普标准则更为注重外部规模京的重要性。
3.战略性贸易政策:该政策是针对一种特殊的不完全竞争市场结构---寡头垄断市场结构提出的。
在寡头垄断市场结构下,政府对贸易活动进行干预目的是改变市场结构或环境,以提高本国企业的国际竞争力,使本国企业获得更多的垄断利润或租金。
战略性贸易政策最为强调的政策主张有两种:一是出口补贴,而是进口保护以促进出口。
4.一国所拥有的两种生产要素的相对比例。
这是一个相对概念,与一国所拥有的生产要素的绝对数量无关。
5.斯托帕-萨谬尔森定理:无论两种要素的所有者倾向于消费哪种商品,国际贸易将提高一国出口产品中密集是用要素(即本国较丰裕的要素)的收益,而降低其进口产品中密集使用要素(即本国较稀缺的要素)的收益。

则贸易结果是,A 只生产苹果,B只生产电脑,不会出现A或者B同时生产苹果和电脑。
这就是完全专业分工5、劳动价值论:劳动价值论是关于价值是一种凝结在商品中的无差别的人类劳动,即抽象劳动所创造的理论。
商品价值决定于体现和物化在商品中的社会必要劳动的理论是人们在长期的历史过程中逐渐认识到的。
劳动决定价值这一思想最初由英国经济学家配第提出。
亚当·斯密和大卫·李嘉图也对劳动价值论做出了巨大贡献。
价值是一个商品经济范畴。
产品成为商品以交换为前提。
交换就有个比率的问题。
价值以这个比率,也就是以交换价值为其具体的表达形式,因此,价值和劳动的关系从而价值的实质往往被模糊了。
事实的真相是:如果不从历史存在者出发,那么,李嘉图所得到的"社会存在"就只能是抽象知识和概念。
马克思论证和研究劳动价值论的方式是:"我又把黑格尔的《逻辑学》浏览了一遍,这在材料加工的方法上帮了我很大的忙。
"但也正是在这里,马克思讥笑了资产阶级工作者:"在所有的现代经济学家中,巴师夏先生的《经济的谐和》集庸俗之大成。
只有癞蛤蟆才能搞出这种谐和的烂泥汤。
"五、计算题1、假设本国生产1 单位食品需要6 单位的劳动,生产1 单位服装需要8 单位劳动;外国生产1 单位食品需要2 单位的劳动,生产1 单位服装需要4 单位劳动。
两国各有8 单位的可用劳动。
(1)哪国在食品生产上具有比较优势?哪国在服装生产上具有比较优势?为什么?(2)列举一个能够使两国进行互惠贸易的交换率并计算本国与外国的贸易获利分别是多少?2、假设A 国生产1 单位小麦需要的劳动为4 小时,生产1 单位布需要的劳动为3 小时; B国生产1 单位小麦需要的劳动为1 小时;生产1 单位布需要的劳动为2 小时,则:(1)以劳动衡量,A、B 两国生产小麦和布的成本各是多少?(2)如果工资率为6 美元,则小麦和布的价格各是多少?(3)如果工资率为1 欧元,则小麦和布的价格各是多少?六、论述题1. 比较优势理论的基本内容是什么?例外情况是什么?2.为什么说国际贸易是双赢的?国际贸易理论里有一个资源禀赋学说,即不同国家,具有不同的资源与不同的生产优势。
克鲁格曼《国际经济学》中文版·第九版 课后习题答案
克鲁格曼《国际经济学》中文版·第九版课后习题答案第一章练习与答案1.为什么说在决定生产和消费时,相对价格比绝对价格更重要?答案提示:当生产处于生产边界线上,资源则得到了充分利用,这时,要想增加某一产品的生产,必须降低另一产品的生产,也就是说,增加某一产品的生产是有机会机本(或社会成本)的。
生产可能性边界上任何一点都表示生产效率和充分就业得以实现,但究竟选择哪一点,则还要看两个商品的相对价格,即它们在市场上的交换比率。
相对价格等于机会成本时,生产点在生产可能性边界上的位置也就确定了。
所以,在决定生产和消费时,相对价格比绝对价格更重要。
2.仿效图1—6和图1—7,试推导出Y商品的国民供给曲线和国民需求曲线。
答案提示:3.在只有两种商品的情况下,当一个商品达到均衡时,另外一个商品是否也同时达到均衡?试解释原因。
答案提示:4.如果生产可能性边界是一条直线,试确定过剩供给(或需求)曲线。
答案提示:5.如果改用Y商品的过剩供给曲线(B国)和过剩需求曲线(A国)来确定国际均衡价格,那么所得出的结果与图1—13中的结果是否一致?答案提示:国际均衡价格将依旧处于贸易前两国相对价格的中间某点。
6.说明贸易条件变化如何影响国际贸易利益在两国间的分配。
答案提示:一国出口产品价格的相对上升意味着此国可以用较少的出口换得较多的进口产品,有利于此国贸易利益的获得,不过,出口价格上升将不利于出口数量的增加,有损于出口国的贸易利益;与此类似,出口商品价格的下降有利于出口商品数量的增加,但是这意味着此国用较多的出口换得较少的进口产品。
对于进口国来讲,贸易条件变化对国际贸易利益的影响是相反的。
7.如果国际贸易发生在一个大国和一个小国之间,那么贸易后,国际相对价格更接近于哪一个国家在封闭下的相对价格水平?答案提示:贸易后,国际相对价格将更接近于大国在封闭下的相对价格水平。
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。

sector(e)None of the aboveAnswer: EEssay Questions1.It is argued that import substitution is a misguided trade policy if the intent is to promote long-term economic growth.Explain the reasons underlying this argument.Answer: Import substitution promotes that economic activity in which the country is relatively inefficient. This lowers the real income at any given time and decreases the resources which can be used for investment purposes, hencelower growth rates. An additional answer is that import substitution by creating a protected domestic marketfails to provide incentives to produce high, or world-class quality —whichmeans this country, cannot market in foreign countries. With such a (perceived) limited market, endogenouseconomic growth will not be forthcoming. Finally, it may be that exposure to world competition has its owndynamic effect promoting economic growth.2.The United States, as it began its long and successful growth in the early 19th Century, consciously promoted domesticproduction through such activities as tariffs, Clay System, and many direct subsidies to railroads, canal companies, farmers (free land) etc. Today we view this blatant example of large scale and extensive import-substitution industrialization as having been very successful. Comment and relate to your answer to question 1.Answer: This is an interesting point and emphasizes that economic models tend to be a-historical. That is, they lack the historic perspective; and thus may be misleading as guides to long run issues, such as economic growth. Thisalso suggests that trade policy per se is almost certainly not sufficient to explain why some countries grow andothers do not.3.Classical and Neoclassical trade theory makes the case that free trade can bring a country to an optimum and economicallyefficient use of its resources; and hence is an optimal trade-policy, if the objective is maximizing long term economic growth. There are those who argue that the experience of the Asian Miracle countries, such as Taiwan, South Korea and Singapore verify this argument in the real world. Explain. There are others who argue that the experience of these countries cannot be used to verify or support the argument above. Explain.Answer: Both arguments may indeed be made. These countries did in fact tend to promote exports in a consistent set of policies. However, they tended to do this via conscious National industrial-policy (e.g., South Korea usi ng“the Japanese system " ), and hence (with the possible exception of Hong Kong) do not provide a good test-tube for the long run effects of a free-trade stance.4.The consensus today is that import —substitution protectionist industrial policy has not served the developing countries' growth ambitions well. This fact proves that policies relying on export- driven growth are the “ winning ticket “ for these countries.Answer: Although there are many who draw precisely this lesson from the “ East Asian Miracle ;of the past half-century, such a conclusion does not necessarily follow logically. Although the fourHPAEs succeeded in their economic as well as in their export sector growth, they differed among themselvesconsiderably in the degree and mannerwith which they abjured protectionist policies. In any case, export-promotion policies may distort relative prices to the same extent as import protectionist policies, and hencemay lead to the same waste and misallocation of national resources.Graphical/Numerical ProblemsVaLieol marginal1.If OmL1 workers are employed in manufacturing then what is the marginal productivity of labor in manufacturing?Answer: OmWm2.If OmL1 workers are employed in manufacturing then what is the marginal productivity of labor in agriculture?Answer: OfWf3.If manufacturing labor were to increase to OmL2, how much value would the economy as a whole gain?Answer: the triangle ABC.4.Why would workers not shift from agriculture to manufacturing in the initial situation where wages are higher in thelatter?Answer: imperfections in the labor market5.If the economy were in the initial position (where OmL1 workers were in manufacturing, what trade policy might gain ABCof economic welfare?Answer: import-substitution giving protection to manufacturing.。

Students will have heard in the media various arguments for and against restrictive trade practices. Some of these arguments are sound, and some are clearly not grounded in fact. This chapter provides a framework for analyzing the economic effects of trade policies by describing the tools of trade policy and analyzing their effects on consumers and producers in domestic and foreign countries. Case studies discuss actual episodes of restrictive trade practices. An instructor might try to underscore the relevance of these issues by having students scan newspapers and magazines for other timely examples of protectionism at work.The analysis presented here takes a partial equilibrium view, focusing on demand and supply in one market, rather than the general equilibrium approach followed in previous chapters. Import demand and export supply curves are derived from domestic and foreign demand and supply curves. There are a number of trade policy instruments analyzed in this chapter using these tools. Some of the important instrumentsof trade policy include specific tariffs, defined as taxes levied as a fixed charge for each unit of a good imported; ad valorem tariffs, levied as a fraction of the value of the imported good; export subsidies, which are payments given to a firm or industry that ships a good abroad; import quotas, which are direct restrictions on the quantity of some good that may be imported; voluntary export restraints, which are quotas on trading that are imposed by the exporting country instead of the importing country; and local content requirements, which are regulations that require that some specified fraction of a good is produced domestically.The import supply and export demand analysis assumes a large country tariff, in which the imposition of a tariff drives a wedge between prices in domestic and foreign markets, and increases prices in the country imposing the tariff and lowers the price in the other country by less than the amount of the tariff. This contrasts with most textbook presentations, which make the small country assumption that the domestic internal price equals the world price plus the tariff. The chapter also discusses how the actual protection provided by a tariff may not equal the tariff rate if imported intermediate goods are used in the production of the protected good. The proper measurement, the effective rate of protection, is described in the text and calculated for a sample problem.The analysis of the costs and benefits of trade restrictions require tools of welfare analysis. The text explains the essential tools of consumer and producer surplus. Consumer surplus on each unit sold is defined as the difference between the actual price and the amount that consumers would have been willing to pay for the product. Geometrically, consumer surplus is equal to the area under the demand curve and above the price of the good. Producer surplus is the difference between the minimum amount for which a producer is willing to sell his product and the price that he actually receives. Geometrically, producer surplus is equal to the area above the supply curve and below the price line. These tools are fundamental to the student’s understanding of the implications of trade policies and should be developed carefully.The costs of a tariff include distortionary efficiency losses in both consumption and production. A tariff provides gains from terms of trade improvement when and if it lowers the foreign export price. Summing the areas in a diagram of internal demand and supply provides a method for analyzing the net loss or gain from a tariff. The gain from a tariff is larger the greater is the decrease in foreign export price from the tariff (as the tariff-imposing country is able to pass some of the costs of the tariff on to foreign exporters). Because large countries will have a larger influence on export prices than small countries, a large country is more likely to gain and, therefore, impose an import tariff.Other instruments of trade policy can be analyzed with this method. An export subsidy operates in exactly the reverse fashion of an import tariff. For example, Europe’s common agricultural policy has raised the price European farmers receive so much that Europe ends up exporting agricultural goods despite very high labor and land costs. The net cost of this shift to consumers is about $30 billion a year.An import quota has similar effects as an import tariff upon prices and quantities, but revenues, in the form of quota rents, accrue to the quota license holders, who are often foreign producers. For example, a quota on sugar imported into the United States has greatly increased the fortunes of foreign sugar producers (many of which are owned by American sugar refiners), at a significant cost to American consumers. Estimates place the cost of each job in the American sugar industry “saved” by protection at $1.75 million. Voluntary export restraints are a form of quotas in which import licenses are held by foreign governments. For example, Japan voluntarily limited exports of cars to the United States to forestall any import tariffs on cars from Japan in the wake of the oil price spike of 1979. The net result of these VER’s was to raise the price of Japanese cars, with the gains accruing directly to Japanese manufacturers. A similar story is happening now with voluntary export restraints on solar panels exported from China to the European Union.Another trade instrument is to mandate local content requirements. These raise the price of imports as well as domestic goods competing with imports but do not yield either tariff revenue or quota rents. The recent construction of the new Bay Bridge linking San Francisco and Oakland is used as a case study. Federal funding was available for this project but would have required the state of California to use a much more costly American contractor as opposed to the significantly cheaper Chinese bid. In the end, the bridge was built through local bonds rather than federal funding because of the local content requirement of federal funding.The Appendix discusses tariffs and import quotas in the presence of a domestic monopoly. Free trade eliminates the monopoly power of a domestic producer, and the monopolist mimics the actions of a firm in a perfectly competitive market, setting output such that marginal cost equals world price. A tariff raises domestic price. The monopolist, still facing a perfectly elastic demand curve, sets output such that marginal cost equals internal price. A monopolist faces a downward-sloping demand curve under a quota. A quota is not equivalent to a tariff in this case. Domestic production is lower and internal price higher when a particular level of imports is obtained through the imposition of a quota rather than a tariff.Answers to Textbook Problems1. The import demand equation, MD, is found by subtracting the Home supply equation from the Homedemand equation. This results in MD= 80 - 40 ⨯P. Without trade, domestic prices and quantities adjust such that import demand is 0. Thus, the price in the absence of trade is 2.2. a. Foreign’s export supply curve, XS, is XS=-40 + 40⨯P. In the absence of trade, the price is 1.b. When trade occurs, export supply is equal to import demand, XS=MD. Thus, using the equationsfrom Problems 1 and 2a, P= 1.50, and the volume of trade is 20.© 2015 Pearson Education Limited48 Krugman/Obstfeld/Melitz •International Economics: Theory & Policy, Tenth Edition3. a. The new MD curve is 80 - 40 ⨯ (P+ t) where t is the specific tariff rate, equal to 0.5. (Note: Insolving these problems, you should be careful about whether a specific tariff or ad valorem tariff is imposed. With an ad valorem tariff, the MD equation would be expressed as MD= 80 - 40 ⨯ (1 + t)P. The equation for the export supply curve by the foreign country is unchanged.MD=XS80 - 40 ⨯ (P+ 0.5) = 40P- 4080 - 20 - 40P= 40P- 4080P= 100P World= 1.25P Home=P World+t= 1.25 + 0.5 = 1.75Trade =MD=XS= (40 ⨯ 1.25) - 40 = 10D Home= 100 - (20 ⨯ 1.75) = 65S Home= 20 + (20 ⨯ 1.75) = 55D Foreign= 80 - (20 ⨯ 1.25) = 55S Foreign= 40 + (20 ⨯ 1.25) = 65b. andc. The welfare of the Home country is best studied using the combined numerical andgraphical solutions presented below in Figure 9-1.Figure 9-1where the areas in the figure are:a.55(1.75 - 1.50) - 0.5(55 - 50)(1.75 - 1.50) = 13.125b. 0.5(55 - 50)(1.75 - 1.50) = 0.625c. (65 - 55)(1.75 - 1.50) = 2.50d. 0.5(70 - 65)(1.75 - 1.50) = 0.625e. (65 - 55)(1.50 - 1.25) = 2.50Consumer surplus change: -(a+ b+ c+ d) =-16.875. Producer surplus change: a= 13.125.Government revenue change: c+ e= 5. Efficiency losses b+ d are exceeded by terms of tradegain e. (Note: In the calculations for the a, b, and d areas, a figure of 0.5 shows up. This is because we are measuring the area of a triangle, which is one-half of the area of the rectangle defined by the product of the horizontal and vertical sides.)4. Using the same solution methodology as in Problem 3, when the Home country is very small relativeto the Foreign country, its effects on the terms of trade are expected to be much smaller. The small country is much more likely to be hurt by its imposition of a tariff. Indeed, this intuition is shown in this problem. The free trade equilibrium is now at the price $1.09 and the trade volume is now 36.40.With the imposition of a tariff of 0.5 by Home, the new world price is $1.045, the internal Home price is $1.545, Home demand is 69.10 units, Home supply is 50.90, and the volume of trade is 18.20. When Home is relatively small, the effect of a tariff on world price is smaller than when Home is relatively large. When Foreign and Home were closer in size, a tariff of 0.5 by Home lowered world price by25 percent, whereas in this case the same tariff lowers world price by about 5 percent. The internalHome price is now closer to the free trade price plus t than when Home was relatively large. In this case, the government revenues from the tariff equal 9.10, the consumer surplus loss is 33.51, and the producer surplus gain is 21.089. The distortionary losses associated with the tariff (areas b+ d) sum to 4.14 and the terms of trade gain (e) is 0.819. Clearly, in this small country example, the distortionary losses from the tariff swamp the terms of trade gains. The general lesson is that the smaller the economy, the larger the losses from a tariff because the terms of trade gains are smaller.5. Dumping is a situation of selling the product at a lower price in the international market compared tothe domestic market. An anti-dumping shows that the companies sell the product lower than the cost of production. When companies follow the dumping and anti-dumping activities, the consumerpurchases the product at a lower price in the dumped country. This leads to the increase in thepurchasing power and welfare of the consumer. The increased competition forces the domesticproducer to cut prices and the overall market price falls.6.An imposition of tariff increases the price of the product at home. This leads to a decrease in quantitydemanded, hence a decrease in import. As demand decreases the income of the exporting country also falls. A decline in income of the export country leads to a reduction in demand for foreign goods.This means, the export of the home country also declines. An imposition of protective tariff increases domestic employment, competing with the foreign industries. This is because, a low import of commodity results in higher demand for the domestic product hence increasing employment.Yes, there might be indirect employment losses in other sectors. The countries which imposes tariff are also unable to export more. This is because an imposition of protective tariff reduces the income of the foreign country, hence reducing demand. Similarly, the domestic industries that use the imported goods as input, also find it expensive to use those imported goods due to the imposition of tariff. This might reduce the employment in other sectors.7. We first use Foreign’s export supply and Home’s import demand curves to determine the newworld price. The Foreign supply of exports curve, with a Foreign subsidy of 0.5 per unit, becomes XS=-40 + 40(1 + 0.5) ⨯P. The equilibrium world price is 1.2, and the internal Foreign price is 1.8.The volume of trade is 32. The Foreign demand and supply curves are used to determine the costs and benefits of the subsidy. Construct a diagram similar to that in the text and calculate the area of the various polygons. The government must provide (1.8 - 1.2)⨯ 32 = 19.2 units of output to support the subsidy. Foreign producer surplus rises due to the subsidy by the amount of 15.3 units of output.Foreign consumer surplus falls due to the higher price by 7.5 units of the good. Thus, the net loss to Foreign due to the subsidy is 7.5 + 19.2 - 15.3 = 11.4 units of output. Home consumers and producers face an internal price of 1.2 as a result of the subsidy. Home consumers surplus rises by 70 ⨯ 0.3 +0.5 (6⨯ 0.3) = 21.9, while Home producer surplus falls by 44 ⨯ 0.3 + 0.5(6 ⨯ 0.3) = 14.1, for a netgain of 7.8 units of output.© 2015 Pearson Education Limited50 Krugman/Obstfeld/Melitz •International Economics: Theory & Policy, Tenth Edition8. a. False, unemployment has more to do with labor market issues and the business cycle than withtariff policy. Empirical estimates suggest that the cost to society of jobs saved through tariffs isexorbitantly high, and tariffs may actually increase unemployment in nonprotected industries.b. False, the opposite is true because tariffs by large countries can actually reduce world prices,which helps offset their effects on consumers.c. This kind of policy might reduce automobile production and Mexico but also would increase theprice of automobiles in the United States and would result in the same welfare loss associatedwith any quota.9. At a price of $10 per bag of peanuts, Acirema imports 200 bags of peanuts. A quota limiting theimport of peanuts to 50 bags has the following effects:a. Set MD= 50 to find the post-quota price: 350 - 15P= 50. The price of peanuts rises to $20 per bag.b. The quota rents are ($20 - $10) ⨯ 50 = $500.c. The consumption distortion loss is 0.5 ⨯ 100 bags ⨯ $10 per bag = $500.d. The production distortion loss is 0.5 ⨯ 50 bags ⨯ $10 per bag = $250.10.An export subsidy would reduce the supply of sugar in Brazil and hence raise the domestic price. Therise in domestic price is less than 20%. The terms of trade will worsen for Brazil. This is because it lowers the price of sugar in the foreign market due to the increased supply. This leads to an additional loss in the terms of trade, equal to the price difference, due to the increased supply in the importing country.The government can impose countervailing import duties to protect the domestic producers and the price in the importing country.11. It would improve the income distribution within the economy because wages in manufacturingwould increase, and real incomes for others in the economy would decrease due to higher prices for manufactured goods. This is true only under the assumption that manufacturing wages arelower than all others in the economy. If they were higher than others in the economy, the tariffpolicies would worsen the income distribution.。

It is argued that import substitution is a misguided trade policy if the intent is to promotelong-term economic growth. Explain the reasons underlying this argument.Answer: Import substitution promotes that economic activity in which the country is relatively inefficient. This lowers the real income at any given time and decreases theresources which can be used for investment purposes, hence lower growth rates. Anadditional answer is that import substitution by creating a protected domesticmarket fails to provide incentives to produce high, or world-class quality—whichmeans this country, cannot market in foreign countries. With such a (perceived)limited market, endogenous economic growth will not be forthcoming. Finally, itmay be that exposure to world competition has its own dynamic effect promotingeconomic growth.2. The United States, as it began its long and successful growth in the early 19th Century,consciously promoted domestic production through such activities as tariffs, Clay’s American System, and many direct subsidies to railroads, canal companies, farmers (free land) etc.Today we view this blatant example of large scale and extensive import-substitutionindustrialization as having been very successful. Comment and relate to your answer toquestion 1.Answer: This is an interesting point and emphasizes that economic models tend to be a-historical. That is, they lack the historic perspective; and thus may be misleadingas guides to long run issues, such as economic growth. This also suggests that tradepolicy per se is almost certainly not sufficient to explain why some countries growand others do not.3. Classical and Neoclassical trade theory makes the case that free trade can bring a country toan optimum and economically efficient use of its resources; and hence is an optimaltrade-policy, if the objective is maximizing long term economic growth. There are those who argue that the experience of the Asian Miracle countries, such as Taiwan, South Korea and Singapore verify this argument in the real world. Explain. There are others who argue that the experience of these countries cannot be used to verify or support the argument above. Explain.Answer: Both arguments may indeed be made. These countries did in fact tend to promote exports in a consistent set of policies. However, they tended to do this via consciousNational industrial-policy (e.g., South Korea usi ng “the Japanese system”), andhence (with the possible exception of Hong Kong) do not provide a good test-tube forthe long run effects of a free-trade stance.4. The consensus today is that import—substitution protectionist industrial policy has not servedthe developing countries’ growth ambitions well. This fact proves that policies relying onexport-driven growth are the “winning ticket” for these countries.Answer: Although there are many who draw precisely this lesson from the “ East Asian Miracle” of the past half-century, such a conclusion does not necessarily followlogically. Although the four HPAEs succeeded in their economic as well as in theirexport sector growth, they differed among themselves considerably in the degree andmanner with which they abjured protectionist policies. In any case,export-promotion policies may distort relative prices to the same extent as importprotectionist policies, and hence may lead to the same waste and misallocation ofnational resources.Graphical/Numerical Problems1.
