Essay Questions

1. “A good cannot be both land- and labor-intensive.” Discuss.

Answer: In a two good, two factor model, such as the original Heckscher-Ohlin framework, the factor intensities are relative intensities. Hence, the relevant statistic is either workers per

acre (or acres per worker); or wage per rental unit (or rental per wage). In order to

illustrate the logic of the statement above, let us assume that the production of a broom

requires 4 workers and 1 acre. Also, let us assume that the production of one bushel of

wheat requires 40 workers and 80 acres. In this case the acres per person required to

produce a broom is one quarter, whereas to produce a bushel of wheat requires 2 acres per

person. The wheat is therefore (relatively) land intensive, and the broom is (relatively)

labor intensive.

2. “No country is abundant in everything.” Discuss.

Answer: the concept of relative (country) factor abundance is (like factor intensities) a relative concept. When we identify a country as being capital intensive, we mean that it has more

capital per worker than does the other country. If one country has more capital worker

than another, it is an arithmetic impossibility that it also has more workers per unit capital.

3. There is frequently a conflict between short-term and long-term interests in trade. Discuss.

Answer: In trade models, the short term is typically defined as that (conceptual) period of time in which both the technology and the amount of factors of production are given and cannot

be changed. When we state that free trade can be shown to be an optimal policy under

certain circumstances, we mean that in the short run, this policy can bring a country to an

optimum level of consumption. However, there is no inconsistency in the proposition that

the optimum short run solution may not be the solution, which maximizes the likelihood

of economic expansion or growth (the long run). For example, a policy which maximizes

consumption may not take into account inter-temporal preferences, and hence may “short-

change” future generations (or those who care for future generations).

4. International trade leads to complete equalization of factor prices. Discuss.

Answer: This statement is typically “true . . . but.” Under a strict and limited set of assumptions, such as the original Heckscher-Ohlin model which excludes country specific technologies;

non- homothetic tastes; factor intensity reversals; large country differences in (relative)

factor abundances, more factors than goods, and an equilibrium solution within the “cone

of specialization”; then it may be demonstrated that internal consistency demands that the

above state d sentence is “true.” However, the minute one relaxes any of the above listed

assumptions one may easily identify solutions, which contradict the factor price

equalization theorem.

5. Countries that are willing to tolerate an unusually high quantity of pollution relative to their supplies

of other factors would tend to export “pollution-intensive” goods. Discuss using the Hechscher-

Ohlin (H.O.) model.

Answer: This statement is badly crafted. It seems to imply that pollution per say is a proper factor of production. That is, just as if you add a worker, you get additional product, so the

marginal product of pollution is positive. The problem here is that pollution is not really

a factor of production, but rather an externality, which may be more typical of imported

goods than exported ones. In such a case, the statement above is false.

6. Countries do not in fact export the goods the H.O. theory predicts. Discuss.

Answer: This statement is not true. Although one may find many cases where it seems to be true

(e.g. the Leontieff Paradox), all one needs to do in order to render the above statement not

(generally) true is to find one counter example. In fact, one can find large subsets of

agricultural and commodity products in which the H.O predictions are generally fulfilled.

Labor-intensive countries such as Bangladesh do in fact export relatively labor-intensive

goods. Capital-intensive countries such as Germany do in fact export capital-intensive

products (at least to South countries). Countries such as Costa R ica (“sunshine abundant”)

tend to export bananas (sunshine-intensive products). The U.S. (a wheat-land-abundant

country) does indeed export wheat (a wheat-land intensive product). In fact, since the

early 1980s, the Leontieff Paradox was not found to describe the U.S. trade data (hence

ratifying the H.O. theory).

7. Why is the H.O. model called the factor-proportions theory?

Answer: The H.O. model explores the nature and the limitations of assuming that the sole determinant of comparative advantage is inter-country differences in (relative) factor

proportions.

8. Why do we observe the Leontief paradox?

Answer: There are many possible answers. They may be classified into three groups. One would argue that the model, or theory is wrong. The other would argue that the theory is correct

(internally consistent and descriptive of real world data), but the real world data is

incorrectly perceived, defined or measured. The third would argue that the statement itself

is wrong, and that in fact the Leontieff paradox itself is not actually observed, but rather is

due to faulty logical rendering of the original model.

9. Why are prices of factors of production not equalized?

Answer: Again this statement may or may not be argued to be true. On the one hand, the large volume and growth in world trade between the United States and other OECD countries

during the 50 years since World War II has clearly been related to a near universal

(average) convergence in real wage levels in these countries, whereas the most obvious

cases in which such a convergence did not take place (North-South countries) also

happened to be cases in which trade was relatively small and “missing.”

There are many theoretical reasons why factor price equalization may not occur. If the

relative country relative abundances are very different, then the theory itself does not

predict that the wage equalization will occur. The same is true of factor intensity reversals

exist within relevant relative wage ranges. Dynamic migration models such as Harris-

Todaro are another class of theory that may suggest that even if the static equilibrium

solution does include the factor-price equalization, the dynamic path of the model may

never reach this solution, so that when observed within any finite time frame, it a lack of

equalization would exist.

10. “The H.O. model remains useful as a way to predict the income distribution effects of trade.”

Discuss.

Answer: The Stolper-Samuelson theorem, one of the basic theorems arising from the

Heckscher-Ohlin model yields an elegant demonstration of the fact that changes in

product prices (such as will occur when trade is expanded or curtailed) telescopes its

effects onto factor prices, so that not only do relative factor returns mirror product prices,

but that actual returns to factors may either rise or fall in real terms. Hence, as a policy

framework, the disproportionate effect trade may have on real incomes of sectors, such as

skilled-labor is quite useful both theoretically and practically (or polemically).

11. It is claimed that the persistence of protectionism is often the result of the fact that those who lose

from trade are usually a much more informed, cohesive and motivated a group than those who gain.

Give a specific example from “real life” that supports this claim.

Answer: The shift of shipbuilding comparative advantage in shipbuilding away from the U.S. has caused economic damage to trained shipbuilders, as well as to owners of shipyards, and to

peripheral businesses located near such shipyards. These groups, and their Congressional

representatives will be very much aware of the damage being done. The gainers would be

those who pay somewhat lower shipping charges, or lower retail prices due to the use of

cheaper (foreign built) ships. Since shipping is typically a very small component of total

retail cost, this gain will hardly be noticeable by any one single group in the economy. 12. One reason international trade has a powerful effect on the distribution of income within countries is

that some factors cannot move costlessly from one industry to another. What is another necessary condition for international trade to have such a strong effect on intra-country income distributions?

Answer: It is necessary that the relative factor intensities differ from industry to industry.

13. Even though it is very clear in the context of the Hecksher-Ohlin model that an expansion of

international trade will create losers as well as winners, economists still claim that the country as a whole gains. The general claim that a country gains even though some identifiable group within it systematically loses requires subjective judgements concerning the relative importance or weights to be given the economic welfares of individuals or groups. Do you believe that this is, in general

scientifically or ethically possible to do? Explain your answer. In what sense, then, do economists nevertheless claim that the country as a whole gains?

Answer: This could be considered to be an intractable issue, for which modern welfare economics really has no solution. For example, in the early 1980s, it was decided not to subject blood

supplies to (at that time) very expensive tests for positive HIV factors, since it was

decided that this would cause blood shortages for large numbers of people, and that the

number of people who might gain from applying the stringent tests was very small. That is,

the good of the many was deemed superior to the good of the few. Unfortunately, the few

happened to be just about every person suffering from Hemophilia at that time. Almost all

of these people died as a result. Was their need really less than the needs of the many??? Quantitative/Graphing Problems

1. Two countries exist in this model, P and R. P is relatively labor (L) abundant, as is evident in the

bottom right horizontal axis. If Country P were to be completely specialized in the labor-intensive product, C, it would be producing at point 4. In fact, it produces both C and P, at point 5. The

(autarky) relative price of C (in terms of F) of Country P is at point 3; and of Country R at point If trade were to open up between these two countries, which would export C and which would export F?

Is this consistent with the Heckscher-Ohlin model? Explain.

Answer: Country R would export F. This is consistent with the H-O model. The country which is relatively capital abundant exports the product which is relatively capital intensive.

2. If trade were to open up between P and R, where would the world terms of trade locate in the figure

above (somewhere on the P C/P F axis)? Would relative wages (w/r) in the two countries become equal?

Is this consistent with the Heckscher-Ohlin model? Explain.

Answer:The terms of trade would settle somewhere between the two autarky relative prices on the P C/P F axis. The relative wages (w/r) will be lower than the highest and higher than the

lowest on the vertical axis above, but will not coincide. This last result is in contradiction

to the factor price equalization expectation we have from the model.

3. Now repeat the exercise but substitute country M for country R. How do the answers differ from

those in question 2 above? Explain the reason for any differences you note.

Answer:All the answers are the same except that one single relative wage will be established for both countries. This happens because the two countries do not differ in relative factor

availability by much, and hence a zone of overlap exists which allows for this result.

4. In autarky, Country P was producing at point

5. With trade, would its production point be found

above or below point 5? Explain why. What must happen in the K/L intensity ratio in the production of each of the products in this country when moving from autarky to free trade?

Answer:The point of production with trade will be above point 5. The country will be shifting its production composition to be more heavily weighted in labor intensive good, C. Within

each industry, the production technique will be more capital intensive, since with the

rising relative wage, the optimal point of production will involve sliding around the

isoquants in the direction of saving on the now relatively more expensive labor.

5. Using the answers to question 4, can you guess which group of producers in Country P might lobby

against free trade?

Answer:In Country P, the owners of the relatively scarce factor of production are the owners of capital. Their relative and real incomes will decrease, and so they may well attempt to

lobby for protectionism, which may prevent the country from moving to a free trade

equilibrium.

6. An Economy can produce good 1 using labor and capital and good 2 using labor and land. The total

supply of labor is 100 units. Given the supply of capital, the outputs of the two goods depends on

labor input as follows:

Labor Input to Good 1 Output of

Good 1

Labor input

to Good 2

Output of

Good 2

0 0 0 0 10 25 10 40 20 38 20 53 30 49 30 62 40 58 40 70 50 66 50 77 60 73 60 83 70 79 70 88 80 84 80 92 90 87 90 95 100 89 100 96

(a) Graph the production functions for good 1 and good 2

(b) Graph the production possibility frontier. Why is it curved?

Answer: The production possibility frontier is curved because of the diminishing returns associated with the expansion of output in the short run in each of the two industries.

7. Using the table from Problem 6, calculate the marginal product of labor for each product, for

different labor inputs.

Answer: e.g. at 50 workers, the marginal product for 1 is 0.75

For product 2 it is 0.65

At 90 workers, the marginal product for 1 is 0.25

For product 2 it is 0.15

李坤望《国际经济学》课后习题答案

第一章 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:参见教材第一章第二节内容,将图1-6a中,以横坐标表示y商品的供给,以纵坐标表示x商品供给,得出相应生产可能性边界线,然后将图1-6b中,以横坐标表示y商品供给,以纵坐标表示y的相对价格,通过类似推导可得出国民供给曲线,国民需求曲线作类似推导可得。 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? 答:两种商品同时达到均衡。一种商品均衡时,由其相对价格,机会成本,需求可知另一种商品得相对价格,机会成本和需求。 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:略,参见书上 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?

国际经济学课后答案解析

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)。重商主义者认为国家富强的方法是尽量使出口大于进口,而出超的结果是金银等贵重金属流入,而一个国家拥有越多的金银,就越富有越强大。现在认为一个国家生产力即生产商品的能力越高则一国越富强 2、亚当.斯密主张的贸易基础和贸易模式分别是什么?贸易所得是如何产生的?斯密倡导什么样的国际贸易基础?他认为政府在经济生活中的适当功能是什么?亚当.斯密主张的贸易基础是绝对优势;贸易模式为两国通过专门生产自己有绝对优势的产品并用其中一部分来交换器有绝对劣势的商品。通过生产绝对优势商品并交换,资源可以被最有效的使用,而且两种商品的产出会有很大的增长,通过交换就会消费比以前更多的商品从而产生了贸易所得;斯密倡导自由贸易,主张自由放任也就是政府尽可能少干涉经济

B) s hift the production possibility curve outward, and increase the production of both goods. C) s hift the production possibility curve outward and decrease the production of the labor-intensive product. D) s hift the production possibility curve outward and decrease the production of the capital-intensive product. E) N one of the above. Answer: D 2) In the 2-factor, 2 good Heckscher-Ohlin model, the two countries differ in A) t astes. B) m ilitary capabilities. C) s ize. D) r elative availabilities of factors of production. E) l abor productivities. Answer: D 3) The Heckscher-Ohlin model differs from the Ricardian model of Comparative Advantage in that the former A) h as only two countries. B) h as only two products. C) h as two factors of production. D) h as two production possibility frontiers (one for each country). E) N one of the above. Answer: C 4) "A good cannot be both land- and labor-intensive." Discuss. Answer: In a two good, two factor model, such as the original Heckscher-Ohlin framework, the factor intensities are relative intensities. Hence, the relevant statistic is either workers per acre (or acres per worker); or wage per rental unit (or rental per wage). In order to illustrate the logic of the statement above, let us assume that the production of a broom requires 4 workers and 1 acre. Also, let us assume that the production of one bushel of wheat requires 40 workers and 80 acres. In this case the acres per person required to produce a broom is one quarter, whereas to produce a bushel of wheat requires 2 acres per person. The wheat is therefore (relatively) land intensive, and the broom is (relatively) labor intensive. 5) "No country is abundant in everything." Discuss. Answer: The concept of relative (country) factor abundance is (like factor intensities) a relative concept. When we identify a country as being capital intensive, we mean that it has more capital per worker than does the other country. If one country has more capital worker than

克鲁格曼《国际经济学》(国际金融)习题答案要点

〈〈国际经济学》(国际金融)习题答案要点 第12章国民收入核算与国际收支 1、如问题所述,GNP仅仅包括最终产品和服务的价值是为了避免重复计算的问题。 在国民收入账户中,如果进口的中间品价值从GNP中减去,出口的中间品价值加 到GNP中,重复计算的问题将不会发生。例如:美国分别销售钢材给日本的丰田公司和美国的通用汽车公司。其中出售给通用公司的钢材,作为中间品其价值不被计算到美国的GNP中。出售给日本丰田公司的钢材,钢材价值通过丰田公司进入日本的GNP,而最终没有进入美国的国民收入账户。所以这部分由美国生产要素创造的中间品价值应该从日本的GNP中减去,并加入美国的GNP。 2、(1)等式12-2可以写成CA =(S P-I)? (T -G)。美国更高的进口壁垒对私人储蓄、投资和政府赤字有比较小或没有影响。(2)既然强制性的关税和配额对这些变量没有影响,所以贸易壁垒不能减少经常账户赤字。 不同情况对经常账户产生不同的影响。例如,关税保护能提高被保护行业的投资,从而使经常账户恶化。(当然,使幼稚产业有一个设备现代化机会的关税保护是合理的。)同时,当对投资中间品实行关税保护时,由于受保护行业成本的提高可能使该行业投资下降,从而改善经常项目。一般地,永久性和临时性的关税保护有不同的效果。这个问题的要点是:政策影响经常账户方式需要进行一般均衡、宏观分析。 3、 (1)、购买德国股票反映在美国金融项目的借方。相应地,当美国人通过他的瑞士银行账户用支票支付时,因为他对瑞士请求权减少,故记入美国金融项目的贷方。这是美国用一个外国资产交易另外一种外国资产的案例。 (2)、同样,购买德国股票反映在美国金融项目的借方。当德国销售商将美国支票存入德国银行并且银行将这笔资金贷给德国进口商(此时,记入美国经常项目的贷 方)或贷给个人或公司购买美国资产(此时,记入美国金融项目的贷方)。最后,银行采取的各项行为将导致记入美国国际收支表的贷方。 (3)、法国政府通过销售其持有在美国银行的美元存款干预外汇市场,代表美国金融项目的借方项目。购买美元的法国公民如果使用它们购买美国商品,这将记入美国国际收支账户经常项目的贷方;如果用来购买美国资产,这将记入美国国际收支账户金融项目的贷方。 (4)假定签发旅行支票的公司使用支票账户在法国进行支付。当此公司支付餐费给 法国餐馆时,记入美国经常项目的借方。签发旅行支票的公司必须销售资产(消耗 其在法国的支票账户)来支付,从而减少了公司在法国拥有的资产,这记入美国金融项目的贷方。 (5)、没有市场交易发生。 (6)离岸交易不影响美国国际收支账户。 4、购买answering machine记入New York收支账户的经常项目借方,记入New Jersey 收支账户经常项目的贷方。当New Jersey的公司将货款存入New York银行时,记入New York的金融项目的贷方和New Jersey金融项目的借方。如果交易用现金进 行支付,则记入New Jersey金融项目的借方和New York金融项目的贷方。New Jersey 获得美元现钞(从New York进口资产),而New York则减少了美元(出口美元资产)。最后的调整类似于金本位制下发生的情况。5、

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
