国际经济学作业任务答案解析-第十章
国际经济学课后练习题答案
绪论部分习题一,填空题1、国际经济学是以(国际经济关系)作为其研究对象的,它包括(国际经济交往活动)和(国际经济相互依存和影响)两层含义。
2、国际贸易的直接原因是(贸易利益的获取),根本原因是(比较优势)、(规模经济)。
3、保护主义性质的贸易政策主要分为(关税壁垒)和(非关税壁垒)两大类。
4、开放经济体系进行宏观经济调控的两个目标是(内部均衡)和(外部均衡)。
5、汇率之所以重要是因为它的实质是(价格),而且它的波动会直接影响一国的(进出口),间接影响一国的(国际收支),进而影响一国的(国内经济均衡)。
6、一个开放的国家,政府制定一项宏观经济政策会带来两种效应,即(溢出效应)和(回振效应)效应。
7、国贸纯理论部分旨在说明(国际贸易产生的原因、贸易模式、贸易利易的产生、贸易利益的分配),国贸政策理论部分旨在说明(保护性的贸易政策对社会经济福利的影响及其理论依据)。
8、西方经济学和国际经济学的共同点在于(研究稀缺资源的优化配置问题)。
二、问答题1、为什么学习国际经济学非常重要?答:①现代世界是一个开放的世界,二战后随着技术创新和制度的不断演进,世界各国为了提高资源配置效率,改善人民经济福利水平,提高综合国力,不断提升开放度,积极地参与国际分工、国际贸易和国际金融活动。
全球经济一体化和区域经济一体化的兴起和发展,跨国公司的迅猛发展,及信息技术革命,使各国国内市场不断延伸和扩展,分工和交易活动不断广化、深化、细化。
各国经济之间的的相互联系、依赖和影响程度不断加强。
因此,专门研究国际经济活动的国际经济学应运而生,并且在经济学中的地位日益提高,成为经济学类学生的一门重要课程。
②西方经济学主要研究在一国范围内经济资源的优化配置及充分就业问题,国际经济学研究在国际格局下经济资源的优化配置及充分就业问题;西方经济学主要研究国内分工贸易等经济活动的规律,而国际经济学则主要研究国际分工贸易等经济活动的规律。
在国际经济活动中,生产要素的流动性、各国制度、法律、语言、文化、宗教、习俗、货币、汇率、各种人为政策等复杂影响使其与国内经济活动呈现出许多不同的规律,故需要一种不同于国内经济活动的理论解释,这样经济学理论才算完整。
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?。

It is argued that import substitution is a misguided trade policy if the intent is to promote long-termeconomic 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 whichcan be used for investment purposes, hence lower growth rates. An additional answer is thatimport substitution by creating a protected domestic market fails to provide incentives toproduce high, or world-class quality—which means this country, cannot market in foreigncountries. With such a (perceived) limited market, endogenous economic growth will not beforthcoming. Finally, it may be that exposure to world competition has its own dynamic effectpromoting economic growth.2. The United States, as it began its long and successful growth in the early 19th Century, consciouslypromoted domestic production through such activities as tariffs, Clay’s American System, and manydirect subsidies to railroads, canal companies, farmers (free land) etc. Today we view this blatantexample 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. This also suggests that trade policy per se is almost certainly notsufficient to explain why some countries grow and others do not.3. Classical and Neoclassical trade theory makes the case that free trade can bring a country to an optimumand economically efficient 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 AsianMiracle 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 using “the Japanese system”), and hence (with the possible exceptionof Hong Kong) do not provide a good test-tube for the long run effects of a free-trade stance.word格式-可编辑-感谢下载支持4. The consensus today is that import—substitution protectionist industrial policy has not served thedevelop ing 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 differedamong themselves considerably in the degree and manner with which they abjuredprotectionist policies. In any case, export-promotion policies may distort relative prices to thesame extent as import protectionist policies, and hence may lead to the same waste andmisallocation of national resources.Graphical/Numerical Problems1.

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)。

国际经济学第五版关键词、复习与思考答案:第10章 区域经济一体化与国际卡特尔
第十章区域经济一体化与国际卡特尔一、关键词1. 区域经济一体化。
是相对于经济全球化而提出的,是指地理区域比较接近的两个或者两个以上国家或地区由政府出面在特定的一体化框架内,通过协调,缔结条约或协定,实施统一的政策或措施,各方互惠互利,以便在经济上实现联合而组成的区域性经济组织。
2. 自由贸易区。
自由贸易区(free trade area)是指成员方通过签订自由贸易协定,逐渐减免甚至取消关税和非关税壁垒,从而逐渐实现商品自由贸易,但各成员方独立地保有对非成员方的关税结构和其他贸易保护措施。
3. 关税同盟。
关税同盟(customs union)是指成员方通过签订条约或协定取消区域内的关税或其他进口限制,实现商品自由贸易,但对非同盟国家实行统一关税税率的一体化组织。
4. 贸易创造。
指各成员之间相互取消关税所带来的贸易规模扩大和福利增加。
5. 贸易转移。
指各成员之间建立共同的对外关税和各成员之间相互取消关税所带来的贸易方向转移,也就是贸易伙伴从组织外国家转换为组织内国家。
6.国际卡特尔。
指跨国界的同类产品的生产者通过某种协议控制产量,划定市场销售份额,将国际市场价格维持在完全竞争价格以上,以获取垄断高额利润为目的的国际寡头垄断的组织形式。
二、复习与思考1. 假定封闭经济状态下产品X的价格在A国是10美元、在B国是8美元、在C国为6美元,并且A国是小国,不能通过贸易影响B国和C国的价格。
如果A国最初对从B国和C国进口的产品X征收非歧视性的100%从价税,那么A国应在国内生产产品X,还是从B国或C国进口产品X?答:如果A国对来自B国和C国的X商品施加100%的从价税,A国将自己生产X商品,因为自行生产的价格是10美元,相比之下,包括关税在内,从B国进口X的商品价格是16美元,从C国进口则是12美元。
2. 以练习题1为基础:(1)如果A国与B国结成关税同盟,A国应在国内生产产品X,还是从B 国或C国进口产品X?(2)A国与B国建立的关税同盟是贸易创造关税同盟,还是贸易转移关税同盟,或两者都不是?答:(1)若A国和B国结成关税同盟,A国从B国进口X商品,这样价格仅为8美元,低于自行生产价格10美元,更低于从C国进口的12美元。

国际经济学课后习题答案
第二章 古典国际贸易理论1. 根据重商主义的观点,一国必须保持贸易顺差。
在两国模型中是否可能?为什么?思路:在两国模型中一国的贸易顺差等于另一国的贸易逆差,不可能出现两国都顺差的情况,重商主义贸易顺差的目标必有一国无法实现。
2. 在分析中国加入世界贸易组织(WTO )的利弊时,有人说“为了能够打开出口市场,我们不得不降低关税,进口一些外国产品。
这是我们不得不付出的代价”;请分析评论这种说法。
思路:这种说法实际是“重商主义”,认为出口有利,进口受损,实际上降低关税多进口本国不具有比较优势的产品,把资源用在更加有效率的产品生产中去再出口,能大大提高一国的福利水平,对一国来说反而是好事。
3. 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。
4.得到好处,5. 假中国总劳动为各国生产计算机的机会成本。

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.

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。

国际经济学习题答案7-12
第七章练习答案1 .关税的主要目的是保护国内生产,但为什么在保护国内生产的同时还会造成消费者福利的损失?答案提示:因为消费者无法消费到更加便宜的国外产品,消费量减少了;国内相对没有效率 的生产代替了国外有效率的生产。
2 .如果将关税改为直接对国内进口替代部门进行生产补贴,那么消费者福利还会受到影响吗?答案提示:不会。
3 .试比较上述两种作法的净福利效应。
答案提示:征收关税将减少消费者的福利,至于整个国家的福利,如果是小国,则福利下降, 如果是大国,福利是下降还是上升,不一定。
采取补贴的做法,将不会减少消费者的福利, 因为产品价格将不会上升;不过,政府支出补贴是一个很大的成本。
4*.试析关税对国内要素实际收入的影响。
(提示:利用斯托伯-萨缪而森定理) 答案提示:关税的征收有利于进口竞争部门密集使用要素的收入提高。
5.假设某一行业(X 1)需要另两个行业(X 2和X 3)的产品作为中间投入,投入产出系数 分别为a21 = 0.2, a 3]= 0,5,三个行业的进口关税分别用%、%和%表示,试计算在 下列情况下X 1的有效保护率。
(1) tj30%、t 2=20%、t 3=10%;(2) tj30%、了0%、t 3=40%;(3) tj30%、t 2=50%、t 3=10%。
答案提示:征收关税前的附加值是:V 1 = 0.3征收关税后的附加值是:匕'=1+t 1 - G+t 2'0,2-G+tJ 0,5有效保护率是:ERP =二匕• 100%1 V 1 6 .进口配额与关税在保护本国产业方面的有什么异同?如果让国内生产者来选择的话,他们会选择哪种措施?答案提示:进口配额与关税都在保护本国产业方面能够发挥作用,不过,进口配额是比关税更加严厉的限制措施。
关税将导致进口产品价格一定幅度的上升(与关税幅度一致),当消费者对此种产品的需求上升以后,产品价格不会进一步上升;配额也会导致进口产品价格的上升,当消费者对此种产品的需求上升以后,由于配额已经确定,产品价格将会进一步上升。
国际经济学课后习题答案
第二章 古典国际贸易理论1. 根据重商主义的观点,一国必须保持贸易顺差。
在两国模型中是否可能?为什么? 思路:在两国模型中一国的贸易顺差等于另一国的贸易逆差,不可能出现两国都顺差的情况,重商主义贸易顺差的目标必有一国无法实现。
2. 在分析中国加入世界贸易组织(WTO )的利弊时,有人说“为了能够打开出口市场,我们不得不降低关税,进口一些外国产品。
这是我们不得不付出的代价”;请分析评论这种说法。
思路:这种说法实际是“重商主义”,认为出口有利,进口受损,实际上降低关税多进口本国不具有比较优势的产品,把资源用在更加有效率的产品生产中去再出口,能大大提高一国的福利水平,对一国来说反而是好事。
3. 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。

(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。
国际经济学课后习题答案
4、马歇尔—勒纳条件:本国出口的价格需求弹性与本国进口的价格需 求弹性之和的绝对值必须大于1,即商品的进出口变化对于价格调整的 反应要大。
3、自由贸易区:是经济一体化组织较低层次的形式,即一体化密切程 度较差的一种形式。成员国间取消关税壁垒,对其他国家各自仍然保持 独立的关税。
4、 关税同盟:经济一体化在发展过程中的一个阶段,它除了在成员国 间取消关税壁垒,而且采取共同的对外关税,关税收入按照既定的比例 进行分配。
7、国际贸易产品生命周期学说:是将周期理论与国际贸易结合起来, 认定国际贸易的发生是由于不同国家之间生产技术方面存在着差距,
技术差距的产生于缩小会改变国际贸易中的比较利益,从而使国际贸 易中所谓比较利益从静态发展成为动态即比较利益从一个或一类国家 转移(传导)到另一个或一类国家,一类产品的生产的优势因而从一 个国家转移到另外的国家,国际贸易的价格也因而发生变化。
第5章 、国际贸易的现代与当代理论(II)
1、 产业内贸易理论:是国际经济学界产生了一种新理论,主要针对国 际贸易大多发生在发达国家之间,并既进口又出口同类产品的现象。产 业内贸易理论,有其理论的假设前提、相应的理论解释。对产品的同质 性、异质性与产业内贸易现象进行解释,并提出了产业内贸易指数的计 算方式。
2、社会无差异曲线:社会无差异曲线是表示社会福利水平一定时,社 会成员之间的效用的不同搭配关系的曲线
3、绝对利益:在某一类商品的生产上,一个经济体在劳动生产率上占 有绝对优势,或其生产所耗费的劳动成本绝对低于另一经济体,若各 个经济体都从事自己占有绝对优势的商品的生产,继而进行交换,那 么双方都可以通过交换得到绝对利益,从而整个世界也可以获得分工 的好处。P16

第二章比较优势理论一、名词解释3、完全专业化:每个国家只生产自己具有相对优势的产品。
假设只有苹果和电脑两种产品,且A在生产苹果上有相对优势,意味着B在电脑上有相对优势。
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。

(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。
《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。

It is argued that import substitution is a misguided trade policy if the intent is topromote long-term economic growth. Explain the reasons underlying this argument.Answer: I mport substitution promotes that economic activity in which the country is relatively inefficient. This lowers the real income at any given time anddecreases the resources which can be used for investment purposes, hencelower growth rates. An additional answer is that import substitution bycreating a protected domestic market fails to provide incentives to producehigh, or world-class quality—which means this country, cannot market inforeign countries. With such a (perceived) limited market, endogenouseconomic growth will not be forthcoming. Finally, it may be that exposureto world competition has its own dynamic effect promoting economicgrowth.2. The United States, as it began its long and successful growth in the early 19thCentury, consciously promoted domestic production through such activities astariffs, Clay’s American System, and many direct subsidies to railroads, canalcompanies, farmers (free land) etc. Today we view this blatant example of largescale and extensive import-substitution industrialization as having been verysuccessful. Comment and relate to your answer to question 1.Answer: T his is an interesting point and emphasizes that economic models tend to be a-historical. That is, they lack the historic perspective; and thus may bemisleading as guides to long run issues, such as economic growth. This alsosuggests that trade policy per se is almost certainly not sufficient to explainwhy some countries grow and others do not.3. Classical and Neoclassical trade theory makes the case that free trade can bring acountry to an optimum and economically efficient 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: B oth arguments may indeed be made. These countries did in fact tend to promote exports in a consistent set of policies. However, they tended to dothis via conscious National industrial-policy (e.g., South Korea using “theJapanese 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-tradestance.4. The consensus today is that import—substitution protectionist industrial policy hasnot served the developing countries’ growth ambitions well. This fact proves that policies relying on export-driven growth are the “winning ticket” for thesecountries.Answer: A lthough there are many who draw precisely this lesson from the “ East Asian Miracle” of the past half-century, such a conclusion does notnecessarily follow logically. Although the four HPAEs succeeded in theireconomic as well as in their export sector growth, they differed amongthemselves considerably in the degree and manner with which they abjuredprotectionist policies. In any case, export-promotion policies may distortrelative prices to the same extent as import protectionist policies, andhence may lead to the same waste and misallocation of national resources.
