model is famous for being elegant and mathematically sophisticated, yetfailing to describe reality. One manifestation of this fact is Trefler ’ s Case of Missing Explain what exactly is missing. In what sense is it missing? How would you explain why it ismissing? How can a relaxation of the identical production functions explain the case of themissing trade?Answer: Trefler demonstrated that the actual volume of world trade is significantly less thanthat which would be predicted by the Heckscher-Ohlin model. One explanation isthatNorth-South trade is especially less than would be predicted by a factor proportions model. Iftechnologies differ in the poorer countries, then it is possible that the cost ofproducing a product, which uses relatively much of their abundant factor may stillbe higher than the cost of producing it in the other country.2.Factor-intensity reversals describe a situation in which the production of a product may be land-intensive in one country, and relatively labor intensive in another (at given relative wage levels).For example, cotton may be land intensive in the U.S., and labor intensive in Egypt where landis relatively scarce and expensive. Suppose factor-intensity reversals were common. How wouldthat affect the conclusion that a country in which land is relatively scarce will notbe the country witha comparative advantage in the land-intensive product?Answer: The answer here is straightforward (though it has various interesting implications).In this case we cannot define or identify a product in terms of its relative factorintensity (at all or any relative wage level). Therefore, the Heckscher-OhlinTheorem is ipso-facto inapplicable.3.Why is it that North-South trade in manufactures seems to be consistent with the results orexpectations generated by the factor-proportions theory of international trade, whereas North-North trade is not?Answer: There is a clear difference in relative factor availabilities between North and South countries, no matter how we define and measure the factors of production. Hence,the factor-proportions theory of trade may be sensibly expected to explain thepattern (though not the volume) of trade between these two groups of countries.However, the North North trade partners do not vary significantly in their relativefactor availabilities, so that other forces, such as scale economies play a relativelylarge role in determining trade patterns.4.One of the commonly used assumptions in deriving the Heckscher-Ohlin model is that tastesare homothetic, or that if the per capita incomes were the same in two countries, theproportions of their expenditures allocated to each product would be the same as it is in theother country. Imagine that this assumption is false, and that in fact, the tastes in each country are strongly biased in favor of the product in which it has a comparative advantage. How would this affect the relationship between relative factor abundance between the two countries, and the nature (factor-intensity) of the product each exports? What if the taste bias favored theimported good?Answer: If in fact national tastes were strongly biased in favor of the product in which the country enjoyed a comparative advantage, then we would expect a bias in favor ofrejecting the Heckscher-Ohlin Theorem in actual trade data. The engine driving theH-O model is that a country should be expected to have a relatively low cost ofproducing the good in which it has a comparative advantage. However, the respectivedemand forces would tend to raise the price of this good, so that the expected patternwould not generally be observed. However, if the tastes were biased in favor of theimported good, then the predictions of the Heckscher-Ohlin Theorem would beexpected to be generally observed.5.Why do you suppose that South-South trade does not conform in volume, but does conformin pattern with expectations generated by the Heckscher-Ohlin model?Answer: The pattern of trade is generally observed to conform to the Heckscher-Ohlin models expectations. That is, the developing countries tend to export labor-intensive goods,such as textiles, and import capital-intensive goods such as machinery. The volumehowever is quite lower than what would be expected from the Neoclassical model.There are many possible reasons, such as financial crises necessitating premia in thefinancing of this trade.6.It has been argued that even if intra-European Union labor mobility were to be completelyremoved, one should not expect to observe massive, or even large reallocations of populations with the E.U. DiscussAnswer: Theoretically, just as completely free trade consistent with Heckscher-Ohlin model (with no complete specialization) is associated with factor price equalization; sodoes completely free labor mobility. It therefore follows that if intra E.U. tradeflourishes, as any restraints on trade there are abolished, the economic incentive forlabor mobility will be removed. Since language and cultural differences remain, wewould expect populations to tend to stay where they are.Quantitative/Graphing Problems1.In Home and Foreign there are two factors of production, land and labor, used to produceonly one good. The land supply in each country and the technology of production are exactly the same. The marginal product of labor in each country depends on employment as follows:Number of Workers Marginal ProductEmployed of Last Worker13022932842752662572482392210211120Initially there are 11 workers employed in Home but only 3 workers in Foreign. Find theeffect of free movement of labor from the high wage to the low wage country. When sucheconomic migration ceases, what will be the levels of production, real wages and the income of landowners in each country?Answer: The total production in the world will increase, since the addition to production (the marginal product of labor) in the target country is larger for each worker than theloss of production (also the marginal product of workers) in the emigration country.The real wages will rise in the emigration country and fall in the immigrationcountry. Landlord incomes will rise in the immigration country and fall in theemigration country.2.Suppose Australia, a land (K)-abundant country and Sri-Lanka, a labor(L)-abundant countryboth produce labor and land intensive goods with the same technology. Following the logic of the Heckscher-Ohlin model from Chapter 4, what will be the incentive for migration once trade is established between these two countries? Now, suppose that a tariff by one countrycreates an incentive for labor migration. From which country to which country will be themigration? Explain how you arrived at your answer.Answer: Once trade is established, there is no longer any incentive for (economic-based) immigration, since the real wages will be equalized in both. If a tariff is establishedin Australia, then the price of the labor intensive good will be higher in Australia,as will be the marginal product of labor and hence the real wage of workers there.Hence, workers will immigrate from Sri-Lanka to Australia until the two domesticprices are equalized.e the diagram below derived from Figure 4-4 to identify the pre-trade situation for Australiaand Sri-Lanka, as discussed in question 2 above. Where on the K/L axis will you find each of the two countries? Which of the two countries has a higher relative wage, w/r? Which product is the labor intensive, and which is the land intensive one? Show where the relative price of cloth to food will be found once trade opens between these two countries. Show where the relative wages of each will appear.Answer: You will find Sri-Lanka to the left of Australia on the K/L axis.Australia has a higher relative wage.Food is the land intensive product.The relative price P C/P F is found between the two autarkic prices.The post trade relative wage is between the two autarkic ones on the vertical axis.ing the figure above from question 3, demonstrate what happens to the composition ofproduction (that is quantity of cloth per 1 unit of food) in Australia once trade is established between the two countries. Which country will export cloth? What happens to the relativeincome of workers in Australia as a result of trade? Does it increase or decrease? Would land owners in Australia lobby for or against free trade? Would land owners in Australia lobby for or against free admittance of immigrant workers?Answer: The proportion of food to cloth will increase in the production of Australia Sri Lanka will export cloth. The relative (and real) incomes of workers will fall in Australia as aresult of trade. Land Owners in Australia should lobby in favor of trade. They wouldalso lobby for free labor mobility (of workers into Australia), since the marginalproduct of labor is high, the owners of land have much (Ricardian) rents to gainfrom an inflow of workers.5.Imagine that the relative capital abundance of Australia was so much greater than that ofSri-Lanka, that we would have to locate Australia far to the right on the K/L axis. If this were so far to the right that there was no area of overlap on the w/r axis, then what product would Australia export? Is this answer different from that in question 4 above? Will the relativewages as calculated now be the same or different from those calculated in question 4?Answer: Australia would still export food, which is the same as in question 4. As a result of trade, wages will fall in Australia and will rise in Sri-Lanka. However, in this case,the wages in Australia will remain higher than in Sri-Lanka, creating an incentive formigration from the latter to the former country.。

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 threelectures.Time permitting, I would, otherwise cover Sections 1 and 2, paying special attention to theRybczynski 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. Note that the two production frontiers have the same verticalor Y intercept in Figure 6 but a different vertical or Y intercept in Figure 3.Compare Figure 7 to Figure 2. Note that the two production frontiers have the samehorizontal or X intercept in Figure 7 but a different horizontal or X intercept in Figure 2.5. See Figure 8 on page 66.6. See Figure 9.7. 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 worldsince 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 comparativeadvantage in capital-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 truecomparative 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 new equilibrium point after the doubling of K in Nation 2, we must assume either than commodity X is inferior or that Nation 2 is too small 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 shiftsto the production of Y, the output of Y rises and the output of X falls, r falls, andPx/Py is likely to rise.2. Capital investments tend to increase real wages because they raise the K/L ratio and the productivity of labor. Technical progress tends to increase K/L and real wages 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 proportionatelymore than theproductivity 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 aftergrowth, then thenation'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 ofcapital is likelyto 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 andcomputer chips with 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 comparativecost advantage?What about Germany?c)What is the range for mutually beneficial trade between the UnitedStates and Germany for each computer chip traded?d)How much would the United States and Germany gain if 1 unit ofbeef is exchanged 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 to Germany, while Germany has a comparative cost advantage in computer chips.c)The range for mutually beneficial trade between the United Statesand Germany for 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 beef traded.2.Given: (1) two nations (1 and 2) which have the same technology butdifferent factor 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 endup 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 supplycurve for A traded 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 aprice 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 tradedcommodityexported by Nation 1 and imported by Nation 2) is P2 and theequilibrium quantityof commodity X traded is Q2.4.a) Identify the conditions that may give rise to trade between twonations.b) What are some of the assumptions on which the Heckscher-Ohlin theory is based?c) What does this theory say about the pattern of trade and effect of trade on factor prices?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 the commodity 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 f actor 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 of commodity 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 completeequalization of relative 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 tangent to the steeper segment ofIndia's production frontier (because of increasing opportunity 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 domestic producers in India to shift labor and capital from the production of food to the 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 price of capital will fall. With labor becoming relative more expensive, producers in India will substitute capital for labor in the production of both textiles 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 a nation such as the United States. However, the pretrade difference in the relative price of textiles between India and the United States is nowsomewhat smaller than before the change in tastes in India. As a result the volume of trade required to equalize relative commodity prices and hence factor prices is smaller than before. That is, India need now export a smaller quantity of textiles and import less food than before for the relative price of textiles in India and the United States to be equalized.Similarly, the gap between real wages and between India and the United States is now smaller and can be more quickly and easily closed (i.e., with a smaller volume of trade).c. Since many of the assumptions required for the completeequalization of relative commodity and factor pricesdo not hold in the real world, great differences can be expected and do in fact remain between real wages inIndia and the United States. Nevertheless, trade would tend to reduce these differences, and the H-O model does identify the forces that must be considered to analyze the effect of trade on the differences in the relative and absolutecommodity and factor prices between India and the United States.5.(a) Explain why the Heckscher-Ohlin trade model needs to beextended.(b) Indicate in what important ways the Heckscher-Ohlin trade modelcan be extended.(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 mode can 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 broadproduct group. Intra-industry trade refers to the international trade in differentiatedproducts.。

See Figure 15.13.The United States has become the most competitive economy in the world since the early-1990 period.1990’s while the data in Table 7.3 refers to the 196514.The data in Table 7.4 seem to indicate that China had a comparative advantage incapital-intensive commodities and a comparative disadvantage in unskilled-laborintensive commodities in 1973. This was very likely due to the many traderestrictions and subsidies, which distorted the comparative advantage o f 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.

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 stopsexpanding.)Ans.: See Figure 1 on page 74.Nations 1 and 2 have different production possibilities curves and differentcommunity indifference maps. With these, they will usually end up with differentrelative commodity prices in autarky, thus making mutually beneficial tradepossible.In the figure, Nation 1 produces and consumes at point A and Px/Py=PA in autarky,while Nation 2 produces and consumes at point A' and Px/Py=PA'. Since P A < P A', Nation 1 has a comparative advantage in X and Nation 2 in Y. Specialization inproduction proceeds u ntil point B in Nation 1 and point B' in Nation 2, at whichP B=P B' and the quantity supplied for export of each commodity exactly equals thequantity demanded f or import. Thus, Nation 1 starts at point A in production andconsumptionin autarky, moves to point B in production, and by exchanging BC ofX for CE of Y reaches point E in consumption. E > A since it involves more of bothX and Y and lieson a higher community indifference curve. Nation 2 starts at A' inproduction andconsumption in autarky, moves to point B' in production, and byexchanging B'C' of Y for C'E' of X reaches point E'in consumption (which exceedsA').At Px/Py=P B=P B', Nation 1 wants to export BC of X for CE of Y, while Nation 2wants to export B'C' (=CE) of Y for C'E' (=BC) of X. Thus, P B=P B'is theequilibrium 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 Cthe 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 orbelow the equilibrium price will not persist. At any other price, QD QS, and P willchange 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 o n 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 resultsin a different production possibilities frontier for each nation, which, unlessneutralized 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 inrelative commodity prices and the basis for mutually beneficial trade between thetwo nations. The difference in relative commodity prices is then translated i nto adifference in absolute commodity prices between the two nations, which is theimmediate cause of trade.– asb) The Heckscher-Ohlin theory (sometimes referred to as the modern theoryopposed 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 ordemand conditions, this difference in factor endowments will result in a difference inrelative factor prices between nations, which in turn leads to a difference in relativecommodity prices and trade. Thus, in the Heckscher-Ohlin theory, the internationaldifference in supply conditions alone determines the pattern of trade. To be noted isthat the two nations need not be identical in other respects in order for internationaltrade 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 thecommodity intensive in its relatively scarce and expensive factor.

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-tradeequilibrium position and using the Heckscher-Ohlin model, trace the effect ofthis 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.

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)。

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.

Note that the two production frontiers have the samehorizontal or X intercept in Figure 7 but a different horizontal or X intercept in Figure 2.5. See Figure 8 on page 66.6. See Figure 9.7. 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.

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.。
国际经济学课后答案(word版)
国际经济学课后答案(word版)第三章复习题(1)本国共有1200单位的劳动,能⽣产两种产品:苹果和⾹蕉。
苹果的单位产品劳动投⼊是3,⾹蕉的单位劳动产品投⼊时2。
a.画出本国的⽣产可能性边界。
b.⽤⾹蕉衡量的苹果的机会成本是多少?c.贸易前,苹果对⾹蕉的相对价格是多少?为什么?答:a.本国的⽣产可能性边界曲线是⼀条直线,在400(1200/3)处与苹果轴相截,在600(1200/2)处与⾹蕉轴相截,如图2-7所⽰。
b.⽤⾹蕉衡量苹果的机会成本是3/2。
⽣产1单位苹果需要3单位的劳动,⽣产1单位⾹蕉需要2单位的劳动。
如果放弃1单位苹果的⽣产,这将释放出3单位的劳动。
这2单位的劳动可以被⽤来⽣产3/2单位的⾹蕉。
c.劳动的流动性可以使得各个部门的⼯资趋同,竞争可以使得商品的价格等于它们的⽣产成本。
这样,相对价格等于相对成本,⽽相对成本等于⼯资乘以苹果的单位劳动产品投⼊。
因为各个部门⼯资相等,所以价格⽐率等于单位产品劳动投⼊的⽐率,即⽣产苹果所需的3单位劳动与⽣产⾹蕉所需的2单位劳动⽐率。
(2)假设本国的情况和习题1相同。
外国拥有800单位的劳动,外国苹果的单位劳动投⼊是5,⾹蕉的单位产品劳动投⼊是1。
a.画出外国的⽣产可能性边界。
b.画出世界相对供给曲线。
答:a.外国的⽣产可能性边界曲线是⼀条直线,在160(800/5)处与苹果轴相截,在 800(800/1)处与⾹蕉轴相截。
如图2-8所⽰。
b.世界相对供给曲线可以由苹果和⾹蕉的相对价格和相对供给量绘出。
如图2-9。
从图2-9可以看出,苹果对⾹蕉的最低相对价格是3/2,在这个价格上,苹果的世界相对供给曲线是⽔平的。
在3/2的相对价格上,本国对苹果的最⼤供给量是400,外国对⾹蕉的供给量是800,这时,相对供给量为1/2。
只要相对价格保持在3/2和5之间,相对供给量就不变。
如果相对价格成为5,两个国家都会⽣产苹果,⾹蕉的产量为零。
这时,相对供给曲线是⽔平的。

Direct Foreign Investment and Multinational FirmsThe Theory of Multinational EnterpriseMultinational Firms in PracticeCase Study: Foreign Direct Investment in the United StatesBox: Taken for a RideSummaryAppendix I: Finding Total Output from the Marginal Product CurveAppendix II: More on Intertemporal Trade⏹Chapter OverviewThis chapter introduces an additional aspect of economic integration, international factor movements. Most notably, this refers to labor and financial capital mobility across countries. An important point emphasized in Chapter 7 is that many of the same forces which trigger international trade in goods between countries will, if permitted, trigger international flows of labor and finances. Students may find this analysis especially interesting in that it sheds light on issues which may involve them personally, such as motives for the 19th and early 20th century waves of emigration to land-abundant but labor-scarce America from land-scarce and labor-abundant Europe and China. Other, more current examples of international factor mobility include the international capital flows associated with the debt crisis of the 1980s, and intertemporal substitution motives behind United States borrowing and foreign direct investment inflows and outflows in the 1980s and 1990s.The chapter proceeds in three main sections. First, a simple model of international labor mobility is presented. Next, intertemporal production and consumption decisions are analyzed in the context of international borrowing and lending. Finally, the role of multinational corporations is discussed. To demonstrate the forces behind international labor mobility, the chapter begins with a model which is quite similar to that presented in Chapter 3. In each country of the world, the real return to labor equals its marginal product in perfectly competitive markets in each of two countries which produce one good using two factors of production. Labor relocates until the marginal products are equal across countries. While the redistribution of labor increases world output and provides overall gains, it also has important income distribution effects. Workers in the originally high wage country are made worse off since wages fall with the inflow of additional workers, and workers in the originally low wage country are made better off. One case study in the text helps illustrate the effects on both source and destination countries and another focuses on the American experience with immigration. It would be interesting for an instructor to discuss the resistance of groups within the United States to migrant farm workers from Mexico and immigration from other low wage countries such as Haiti. The case study notes that while immigration into the U.S. is a highly contentious political issue, on purely economic grounds, the aggregate impact on the U.S. economy is probably relatively small.An analysis of international capital movements involves the consideration of intertemporal trade. The important point here is that the real rate of interest differs across countries, and international factor movements provide gains to both borrowers and lenders. The analysis presented here is analogous to that in Chapter 5; instead of choosing between consumption of goods at any point in time, the analysis focuses on a one good world where the choice at a point in time is between future and present consumption. An intertemporal production possibilities frontier replaces the PPF and the intertemporal price line replaces the relative price line. Analysis of the gains from intertemporal trade, the size of borrowing and lending, and the effects of taxes on capital transfers follow. The appendix presents this model in greater detail. The final issue addressed in this chapter concerns direct foreign investment and multinational firms. Direct foreign investment differs from other capital transfers in that it involves the acquisition of control of a company. The theory of multinational firms is not well developed. Important points of existing theory are that decisions concerning multinationals are based upon concerns involving location and internalization. Location decisions are based upon barriers to trade and transportation costs. Internalization decisions focus on vertical integration and technology transfers. Multinationals facilitate shifts such that factor prices move in the direction which free trade would cause. The income distribution effects of direct foreign investment are politically charged and in other chapters are discussed in further detail.The political dimension of international factor movements differs from that of international trade. Class discussion on these distinctions could focus on who wins and who loses from each and, more specifically, issues such as the role of multinationals or the responsibility of host countries to guest workers. For example, one interesting topic for discussion is the effect of labor mobility as a component of integration within the European Union. (This topic is developed further in Chapter 20.)Answers to Textbook Problems1. The marginal product of labor in Home is 10 and in Foreign is 18. Wages are higher in Foreign, soworkers migrate there to the point where the marginal product in both Home and Foreign is equated.This occurs when there are 7 workers in each country, and the marginal product of labor in each country is 14.2. If immigration is limited, migration will still be from Home to Foreign, but now, instead of fourworkers moving, only two will be allowed to do so. Workers originally in Foreign do worse after the immigration since wages fall as the marginal product of labor falls due to the increase in the number of workers (though wages do not fall as much as they would have with unfettered immigration).Foreign landowners are better off as they have more workers at lower wages with the inflow ofimmigrants, though they are not as well off as they would have been with unfettered immigration.Home landowners see the opposite effect, fewer and more expensive workers; again, this effect is stronger with the movement of four workers rather than just two. Finally, workers who stayhome see their marginal product go up from 10 to 12, and hence their wages rise. Workers who move see their marginal product move from 10 to 16, suggesting an even larger increase in wages than the workers who stay (the two workers that move also do better than if four workers hadmoved as in Question 1). Part b suggests that workers who move are big winners in Mexico—U.S.immigration. That is consistent with the answer here. The workers moving from Home to Foreign see the largest impact on their wages since immigration is limited. If immigration were opened,following the logic of this question, wages in the U.S. would fall more. Thus, there would be a bigger (negative) impact on U.S. workers and a less positive impact on workers that move, but a morepositive impact on workers that stay behind in Mexico as the larger immigration flow from Mexico will cause the marginal product of labor of those left behind to rise more than when immigration is restricted.3. Direct foreign investment should reduce labor flows from Mexico into the United States becausedirect foreign investment causes a relative increase in the marginal productivity of labor in Mexico, which in turn causes an increase in Mexican wages and reduces the incentive for emigration to the United States.4. There is no incentive to migrate when there is factor price equalization. This occurs when bothcountries produce both goods and when there are no barriers to trade (the problem assumestechnology is the same in the two countries). A tariff by Country A increases the relative price of the protected good in that country and lowers its relative price in the Country B. If the protected good uses labor relatively intensively, the demand for labor in Country A rises, as does the return to labor, and the return to labor in the Country B falls. These results follow from the Stolper-Samuelsontheory, which states that an increase in the price of a good raises the return to the factor usedintensively in the production of that good by more than the price increase. These international wage differentials induce migration from Country B to Country A.5.a. From the diagram we see that the number of workers in Guatarica declines and the number ofworkers in Costamala increases.b. Wages in Guatarica and Costamala both increase.c. GDP increases in Costamala but decreases in Guatarica.d. Capital rents decline in Guatarica, but the change is ambiguous in Costamala.6. The analysis of intertemporal trade follows directly the analysis of trade of two goods. Substitute“future consumption” and “present consumption” for “cloth” and “food.” The relevant relativeprice is the cost of future consumption compared to present consumption, which is the inverse of the real interest rate. Countries in which present consumption is relatively cheap (which havelow real interest rates) will “export” present consumption (i.e., lend) to countries in which prese nt consumption is relatively dear (which have high real interest rates). The equilibrium real interest rate after borrowing and lending occur lies between that found in each country before borrowing and lending take place. Gains from borrowing and lending are analogous to gains from trade—there is greater efficiency in the production of goods intertemporally.7. Foregoing current consumption allows one to obtain future consumption. There will be a biastowards future consumption if the amount of future consumption which can be obtained by foregoing current consumption is high. In terms of the analysis presented in this chapter, there is a bias towards future consumption if the real interest rate in the economy is higher in the absence of international borrowing or lending than the world real interest rate.a. The large inflow of immigrants means that the marginal product of capital will rise as moreworkers enter the country. The real interest rate will be high, and there will be a bias towardsfuture consumption.b. The marginal product of capital is low, and thus, there is a bias towards current consumption.c. The direction of the bias depends upon the comparison of the increase in the price of oil andthe world real interest rate. Leaving the oil in the ground provides a return of the increase in the price of oil whereas the world real interest rate may be higher or lower than this increase.d. Foregoing current consumption allows exploitation of resources, and higher future consumption.Thus, there is a bias towards future consumption.e. The return to capital is higher than in the rest of the world (since the country’s rate of growthexceeds that of the rest of the world), and there is a bias toward future consumption.8. a. $10 million is not a controlling interest in IBM, so this does not qualify as direct foreigninvestment. It is international portfolio diversification.b. This is direct foreign investment if one considers the apartment building a business which paysreturns in terms of rents.c. Unless particular U.S. shareholders will not have control over the new French company, this willnot be direct foreign investment.d. This is not direct foreign investment since the Italian company is an “employee,” but not theones who ultimately control, the company.9. A company might prefer to set up its own plant as opposed to license it for a number of reasons,many of which relate to the discussion of location and internalization discussed in the chapter. In many cases it might be less expensive to carry out transactions within a firm than between twoindependent firms. Often, if proprietary technology is involved or if the quality reputation of a firm is particularly crucial, a firm may prefer to keep control over production rather than outsource.10. In terms of location, the Karma company has avoided Brazilian import restrictions. In terms ofinternalization, the firm has retained its control over the technology by not divulging its patents.。

This is not a core chapter and I would skip it, except for sections 7-4 to 7-8 dealing with theEuropean Union (EU), The European Free Trade Association, the North American FreeTrade Agreement (NAFTA), and the Southern Common Market (Mercosur).2. I would take two classes to cover the material. Case Studies 7-1 to 7-4 can be used for a very stimulating class discussion.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, Nation A will import commodityX 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. The formation by Nation A of a customs union with Nation B leads to trade creationonly because Nation A replaces the 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, Nation A 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. The formation by Nation A of a customs union with Nation B leads not only to tradecreation but also to trade diversion because it replaces lower-cost imports of commodity X of $6 (from the point of view of Nation A as a whole) with higher priced imports of Commodity X from Nation B at $8.Specifically, Nation A's importers do not import commodity X from Nation C becausethe tariff-inclusive price of commodity X from Nation C is $9 as compared with theno-tariff price of $8 for imports of commodity X from Nation B. However, since thegovernment of Nation A collects the $3 tariff per unit on imports of commodity Xfrom Nation C, the net effective price for imports of commodity X from Nation C isreally $6 for Nation A as a whole.-54-5. a. See Figure 1 below.b. The net gain from the trade-diverting customs union shown in Figure 1 is given byC'JJ'+B'HH'-MJ'H'N. As contrasted with the case in Figure 7-1 in the text, however,the sum of the areas of the two triangles (measuring gains) is here 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.6. A customs union that leads to both trade creation and trade diversion is more likely to lead to a net positive welfare gain of the nation joining the union (1) the smaller is the relative inefficiency of the union member in relation to the non-union member and (2) the higher is the level of the tariff imposed by the customs union on the non-union member.7. The dynamic benefits resulting from the formation of a customs union are (1) increasedcompetition, (2) economies of scale, (3) stimulus to investment, and (4) better utilizationof economic resources. These are likely to be much more significant than the static benefits.8. See Figure 2 below. The formation of the customs union has no effect.9. NAFTA created much more controversy because the very low wages in Mexico led togreat fears of large job losses in the U. S.10. 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 EUspills into a greater demand for American products, which benefits the U. S.Fig 7.1xPFig 7.2xP-55-Multiple-choice Questions:1.

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(克鲁格曼)课后习题答案1-8章
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—乙试推导出丫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. 如果改用丫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。
& 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9* .为什么说两个部门要素使用比例的不同会导致生产可能性边界曲线向外凸?答案提示:第二章答案1.根据下面两个表中的数据,确定(1)贸易前的相对价格;(2)比较优势型态。

国际经济学英文版上册(第八版)章节练习第七章
International Economics, 8e (Krugman)Chapter 7 International Factor Movements1) If the world attained a perfect Heckscher-Ohlin model equilibrium with trade, thenA) workers in the labor abundant country would migrate to the capital abundant country.B) workers in the labor abundant country would wish to migrate to the capital abundant country.C) workers in the labor abundant country would have no desire to migrate to the capital abundantcountry.D) workers in the capital abundant country would wish to migrate to the labor abundant country.E) workers in the capital abundant country would migrate to the labor abundant country.Answer: C2) During the mass migration period of late 19th-early 20th centuries,A) wages rose in the origin countries and fell in the destination countries.B) wages fell in the origin countries and rose in the destination countries.C) wages generally rose faster in the origin countries.D) wages generally rose faster in the destination countries.E) wages generally fell faster in the origin countries.Answer: C3) International labor mobilityA) leads to wage convergence by raising wages in destination country and lowering in source country.B) is in accordance with the specific factors model.C) is in accordance with the Heckscher-Ohlin factor proportions model.D) leads to wage convergence by raising wages in source and lowering them in destination country.E) is in accordance with scale economy model.Answer: D4) In theory, labor mobility isA) a complete complement to trade flows.B) a partial complement to trade flows.C) a complete substitute for trade flows.D) a partial substitute for trade flows.E) None of the above.Answer: C5) In practice, international labor mobility isA) a complete complement to trade flows.B) a partial complement to trade flows.C) a complete substitute for trade flows.D) a partial substitute for trade flows.E) None of the above.Answer: D6) In a typical short-run production function, as labor increasesA) the marginal product of capital decreases.B) the overall product of labor decreases.C) the average product of labor decreases.D) the marginal product of labor decreases.E) None of the above.Answer: D7) Using the production function model, the real wage is determined byA) the amount of migration.B) the marginal product of capital.C) the marginal product of labor.D) the rents.E) None of the above.Answer: C8) If initially wages are higher in Home than in Foreign, then a movement of workers from Foreign to HomewillA) lower the marginal product of labor in Foreign.B) raise total product in Foreign.C) raise the income of land owners in Foreign.D) raise the income of land owners in Home.E) None of the above.Answer: D9) A redistribution of workers from low to high real wage countries will eventually result inA) lead to equal real wages in all countries.B) lead to equal income distribution between land owners and workers.C) lower the world's output as a whole.D) a higher level of international investment and trade.E) None of the above.Answer: A10) It may be argued that international labor mobility and trade are substitutes one from the other. Explain.Answer: workers earning lower real wages will have an incentive to move to a higher-wage country. Using the Neo-Classical model framework, this means that countries with relative more labor per unit capitalmay be said to have a relative abundance of labor (or a comparative advantage in labor). They willtherefore export their labor. Turning to the Neo-Classical trade model, we know that a country that isrelatively labor abundant will export products (and enjoy comparative advantage) in products thatembody relatively more labor. Hence, trade exports labor indirectly embodied in products. This allowsthe workers to raise their real wage instead of doing it by physically moving to the capital rich country.11) It may be argued that, although theoretically international labor mobility and international trade may besubstitutes one for the other, inductive inferences drawn from real world observations suggest that the two are actually complementary. Give an example.Answer: One can easily observe that sales of Irish Whiskey are relatively robust in neighborhoods with large populations of Irish descent. Alternatively, one finds sales of imported Indian foods in specializedrestaurants in areas with relatively large populations of immigrants from India. Or Mexican beer inareas with large or rapidly expanding populations from Mexico. This may easily be explained by the"Home good" taste bias of populations. Along with international labor migrations come their tastes infoods as well as other products.12) One concomitant of international labor mobility is the phenomenon known as the "brain drain." This refers tothe immigration (or emigration) of the "best and brightest." Generally countries tend to encourage suchimmigration. Explain why. At times, countries actually encourage such "emigration." Explain why.Answer: The answer to the first question is easy. The highly skilled workers' marginal product is likely to be markedly higher than the average product in the host country. The host country reaps the benefits ofeducation expended by other countries' educational infrastructures. The answer to the secondquestion is more difficult. An example is that during 2000, the Prime Minister of India lobbied for achange in U.S. immigration laws so as to encourage the employment of more Indian engineers andcomputer programmers in the U.S. The answer to this seemingly paradoxical action may be related tothe observed complementarity of international labor mobility and international trade. The presence ofIndian engineers in the U.S. may actually encourage the importation of Indian products and servicesin the computer field.13) In Home and Foreign there are two factors of production, land and labor, used to produce only one good.The land supply in each country and the technology of production are exactly the same. The marginalproduct of labor in each country depends on employment as follows:Initially there are 11 workers employed in Home but only 3 workers in Foreign. Find the effect of freemovement of labor from the high wage to the low wage country. When such economic migration ceases, what will be the levels of production, real wages and the income of landowners in each country?Answer: The total production in the world will increase, since the addition to production (the marginal product of labor) in the target country is larger for each worker than the loss of production (also the marginalproduct of workers) in the emigration country. The real wages will rise in the emigration country andfall in the immigration country. Landlord incomes will rise in the immigration country and fall in theemigration country.14) Suppose Australia, a land (K)-abundant country and Sri-Lanka, a labor(L)-abundant country both producelabor and land intensive goods with the same technology. Following the logic of the Heckscher-Ohlin model from Chapter 4, what will be the incentive for migration once trade is established between these twocountries? Now, suppose that a tariff by one country creates an incentive for labor migration. From which country to which country will be the migration? Explain how you arrived at your answer.Answer: Once trade is established, there is no longer any incentive for (economic-based) immigration, since the real wages will be equalized in both. If a tariff is established in Australia, then the price of the laborintensive good will be higher in Australia, as will be the marginal product of labor and hence the realwage of workers there. Hence, workers will immigrate from Sri-Lanka to Australia until the twodomestic prices are equalized.15) International borrowing and lending may be interpreted as one form ofA) intermediate trade.B) inter-temporal trade.C) trade in services.D) unrequited international transfers.E) None of the above.Answer: B16) If one observes that Japan was traditionally a net foreign lender, one could conclude that relative to itsinternational trade and financial partnersA) Japan's inter-temporal production possibilities are biased toward future consumption.B) Japan's inter-temporal production possibilities are larger than that of the other countries.C) Japan's inter-temporal production possibilities are biased toward present consumption.D) Japan's inter-temporal production possibilities are not biased.E) None of the above.Answer: C17) Rapidly growing developing countries tend to be borrowers on the international capital markets. From thisinformation we may surmise that they have a comparative advantage inA) capital goods.B) future income.C) disposable income.D) consumer goods.E) present income.Answer: B18) International labor mobility is different from capital mobility in thatA) the first is a human and family decision, whereas the latter is not.B) the first is a real transfer from one country to the other, whereas the latter is a financial transaction.C) the first is motivated by the desire to receive a higher economic return, whereas the latter is merely aninter-bank transfer.D) The first results in equalization of real factor returns, whereas the latter does not.E) None of the above.Answer: B19) The relative price of future consumption isA) the interest rate.B) unknown at any given time.C) the real interest rate.D) the relative interest rate.E) None of the above.Answer: C20) A country that has a comparative advantage in future production of consumption goodsA) will tend to be an international borrower.B) will tend to have low real interest rates.C) will tend to be an international investor or lender.D) will tend to have good work ethics.E) None of the above.Answer: A21) A U.S. multinational corporationA) has a controlling share in a foreign subsidiary and is not itself foreign controlled.B) is foreign controlled and has no controlling share in a foreign company.C) has a controlling share in a foreign subsidiary and may itself be foreign controlled by a foreigncompany.D) is a U.S. company whose major markets are outside the United States.E) None of the above.Answer: C22) Why a good is produced in two different countries is known as the question ofA) internalization.B) vertical integration.C) exploitation.D) location.E) None of the above.Answer: D23) Most U.S. direct foreign investment occurs inA) communications.B) agriculture.C) petroleum.D) manufacturing.E) None of the above.Answer: D24) Most foreign direct investment in the United States occurs inA) communications.B) agriculture.C) petroleum.D) manufacturing.E) None of the above.Answer: D25) Direct foreign investment may take any of the following forms exceptA) investors buying bonds of an existing firm overseas.B) the creation of a wholly owned business overseas.C) the takeover of an existing company overseas.D) the construction of a manufacturing plant overseas.E) None of the above.Answer: A26) Multinational corporationsA) increase the transfer of technology between nations.B) make it harder for nations to foster activities of comparative advantage.C) always enjoy political harmony in host countries in which their subsidiaries operate.D) require governmental subsidies in order to conduct worldwide operations.E) None of the above.Answer: A27) American labor unions have recently maintained that U.S. multinational corporations have beenA) exporting American jobs by investing overseas.B) exporting American jobs by keeping investment in the United States.C) importing cheap foreign labor by shifting U.S. investment overseas.D) importing cheap foreign workers by keeping U.S. investment at home.E) None of the above.Answer: A28) The shift of labor-intensive assembly operations from the United States to Mexican maqiladora may be bestexplained in terms of a theory ofA) location.B) vertical integration.C) horizontal integration.D) internalization.E) None of the above.Answer: A。

Direct Foreign Investment and Multinational FirmsThe Theory of Multinational EnterpriseMultinational Firms in PracticeCase Study: Foreign Direct Investment in the United StatesBox: Taken for a RideSummaryAppendix I: Finding Total Output from the Marginal Product CurveAppendix II: More on Intertemporal Trade⏹Chapter OverviewThis chapter introduces an additional aspect of economic integration, international factor movements. Most notably, this refers to labor and financial capital mobility across countries. An important point emphasized in Chapter 7 is that many of the same forces which trigger international trade in goodsbetween countries will, if permitted, trigger international flows of labor and finances. Students may find this analysis especially interesting in that it sheds light on issues which may involve them personally, such as motives for the 19th and early 20th century waves of emigration to land-abundant but labor-scarce America from land-scarce and labor-abundant Europe and China. Other, more current examples of international factor mobility include the international capital flows associated with the debt crisis of the 1980s, and intertemporal substitution motives behind United States borrowing and foreign direct investment inflows and outflows in the 1980s and 1990s.The chapter proceeds in three main sections. First, a simple model of international labor mobility is presented. Next, intertemporal production and consumption decisions are analyzed in the context of international borrowing and lending. Finally, the role of multinational corporations is discussed. To demonstrate the forces behind international labor mobility, the chapter begins with a model which is quite similar to that presented in Chapter 3. In each country of the world, the real return to labor equalsits marginal product in perfectly competitive markets in each of two countries which produce one good using two factors of production. Labor relocates until the marginal products are equal across countries. While the redistribution of labor increases world output and provides overall gains, it also has important income distribution effects. Workers in the originally high wage country are made worse off since wages fall with the inflow of additional workers, and workers in the originally low wage country are made better off. One case study in the text helps illustrate the effects on both source and destination countries and another focuses on the American experience with immigration. It would be interesting for an instructor to discuss the resistance of groups within the United States to migrant farm workers from Mexico and immigration from other low wage countries such as Haiti. The case study notes that while immigration into the U.S. is a highly contentious political issue, on purely economic grounds, the aggregate impact on the U.S. economy is probably relatively small.An analysis of international capital movements involves the consideration of intertemporal trade. The important point here is that the real rate of interest differs across countries, and international factor movements provide gains to both borrowers and lenders. The analysis presented here is analogous to that in Chapter 5; instead of choosing between consumption of goods at any point in time, the analysis focuses on a one good world where the choice at a point in time is between future and present consumption. An intertemporal production possibilities frontier replaces the PPF and the intertemporal price line replaces the relative price line. Analysis of the gains from intertemporal trade, the size of borrowing and lending, and the effects of taxes on capital transfers follow. The appendix presents this model in greater detail.The final issue addressed in this chapter concerns direct foreign investment and multinational firms. Direct foreign investment differs from other capital transfers in that it involves the acquisition ofcontrol of a company. The theory of multinational firms is not well developed. Important points of existing theory are that decisions concerning multinationals are based upon concerns involvinglocation and internalization. Location decisions are based upon barriers to trade and transportationcosts. Internalization decisions focus on vertical integration and technology transfers. Multinationals facilitate shifts such that factor prices move in the direction which free trade would cause. The income distribution effects of direct foreign investment are politically charged and in other chapters arediscussed in further detail.The political dimension of international factor movements differs from that of international trade. Class discussion on these distinctions could focus on who wins and who loses from each and, more specifically, issues such as the role of multinationals or the responsibility of host countries to guest workers. For example, one interesting topic for discussion is the effect of labor mobility as a component of integration within the European Union. (This topic is developed further in Chapter 20.)Answers to Textbook Problems1. The marginal product of labor in Home is 10 and in Foreign is 18. Wages are higher in Foreign, soworkers migrate there to the point where the marginal product in both Home and Foreign is equated.This occurs when there are 7 workers in each country, and the marginal product of labor in eachcountry is 14.2. If immigration is limited, migration will still be from Home to Foreign, but now, instead of fourworkers moving, only two will be allowed to do so. Workers originally in Foreign do worse after the immigration since wages fall as the marginal product of labor falls due to the increase in the number of workers (though wages do not fall as much as they would have with unfettered immigration).Foreign landowners are better off as they have more workers at lower wages with the inflow ofimmigrants, though they are not as well off as they would have been with unfettered immigration.Home landowners see the opposite effect, fewer and more expensive workers; again, this effectis stronger with the movement of four workers rather than just two. Finally, workers who stayhome see their marginal product go up from 10 to 12, and hence their wages rise. Workers who move see their marginal product move from 10 to 16, suggesting an even larger increase in wages than theworkers who stay (the two workers that move also do better than if four workers hadmoved as in Question 1). Part b suggests that workers who move are big winners in Mexico—U.S.immigration. That is consistent with the answer here. The workers moving from Home to Foreign see the largest impact on their wages since immigration is limited. If immigration were opened, following the logic of this question, wages in the U.S. would fall more. Thus, there would be a bigger (negative) impact on U.S. workers and a less positive impact on workers that move, but a more positive impact on workers that stay behind in Mexico as the larger immigration flow from Mexico will cause the marginal product of labor of those left behind to rise more than when immigration is restricted.3. Direct foreign investment should reduce labor flows from Mexico into the United States becausedirect foreign investment causes a relative increase in the marginal productivity of labor in Mexico, which in turn causes an increase in Mexican wages and reduces the incentive for emigration to the United States.4. There is no incentive to migrate when there is factor price equalization. This occurs when bothcountries produce both goods and when there are no barriers to trade (the problem assumestechnology is the same in the two countries). A tariff by Country A increases the relative price of the protected good in that country and lowers its relative price in the Country B. If the protected good uses labor relatively intensively, the demand for labor in Country A rises, as does the return to labor, and the return to labor in the Country B falls. These results follow from the Stolper-Samuelson theory, which states that an increase in the price of a good raises the return to the factor used intensively in the production of that good by more than the price increase. These international wage differentials induce migration from Country B to Country A.5.a. From the diagram we see that the number of workers in Guatarica declines and the number ofworkers in Costamala increases.b. Wages in Guatarica and Costamala both increase.c. GDP increases in Costamala but decreases in Guatarica.d. Capital rents decline in Guatarica, but the change is ambiguous in Costamala.6. The analysis of intertemporal trade follows directly the analysis of trade of two goods. Substitute“future consumption” and “present consumption” for “cloth” and “food.” The relevant relativeprice is the cost of future consumption compared to present consumption, which is the inverse ofthe real interest rate. Countries in which present consumption is relatively cheap (which havelow real interest rates) will “export” present consumption (i.e., lend) to countries in which present consumption is relatively dear (which have high real interest rates). The equilibrium real interest rate after borrowing and lending occur lies between that found in each country before borrowing and lending take place. Gains from borrowing and lending are analogous to gains from trade—there is greater efficiency in the production of goods intertemporally.7. Foregoing current consumption allows one to obtain future consumption. There will be a bias towardsfuture consumption if the amount of future consumption which can be obtained by foregoing current consumption is high. In terms of the analysis presented in this chapter, there is a bias towards future consumption if the real interest rate in the economy is higher in the absence of internationalborrowing or lending than the world real interest rate.a. The large inflow of immigrants means that the marginal product of capital will rise as moreworkers enter the country. The real interest rate will be high, and there will be a bias towardsfuture consumption.b. The marginal product of capital is low, and thus, there is a bias towards current consumption.c. The direction of the bias depends upon the comparison of the increase in the price of oil andthe world real interest rate. Leaving the oil in the ground provides a return of the increase in the price of oil whereas the world real interest rate may be higher or lower than this increase.d. Foregoing current consumption allows exploitation of resources, and higher future consumption.Thus, there is a bias towards future consumption.e. The return to capital is higher than in the rest of the world (since the country’s rate of growthexceeds that of the rest of the world), and there is a bias toward future consumption.8. a. $10 million is not a controlling interest in IBM, so this does not qualify as direct foreigninvestment. It is international portfolio diversification.b. This is direct foreign investment if one considers the apartment building a business which paysreturns in terms of rents.c. Unless particular U.S. shareholders will not have control over the new French company, this willnot be direct foreign investment.d. This is not direct foreign investment since the Italian company is an “employee,” but not the on eswho ultimately control, the company.9. A company might prefer to set up its own plant as opposed to license it for a number of reasons,many of which relate to the discussion of location and internalization discussed in the chapter. In many cases it might be less expensive to carry out transactions within a firm than between twoindependent firms. Often, if proprietary technology is involved or if the quality reputation of a firm is particularly crucial, a firm may prefer to keep control over production rather than outsource.10. In terms of location, the Karma company has avoided Brazilian import restrictions. In terms ofinternalization, the firm has retained its control over the technology by not divulging its patents.。

The Heckscher-Ohlin model is famous for being elegant and mathematically sophisticated, yetfailing to describe reality. One manifestation of this fact is Trefler’s Case of Missing Trade.Explain what exactly is missing. In what sense is it missing? How would you explain why it is missing? How can a relaxation of the identical production functions explain the case of themissing trade?Answer: Trefler demonstrated that the actual volume of world trade is significantly less than that which would be predicted by the Heckscher-Ohlin model. One explanation isthatNorth-South trade is especially less than would be predicted by a factor proportions model. If technologies differ in the poorer countries, then it is possible that the cost ofproducing a product, which uses relatively much of their abundant factor may still behigher than the cost of producing it in the other country.2.Factor-intensity reversals describe a situation in which the production of a product may beland-intensive in one country, and relatively labor intensive in another (at given relative wage levels). For example, cotton may be land intensive in the U.S., and labor intensive in Egyptwhere land is relatively scarce and expensive. Suppose factor-intensity reversals were common.How would that affect the conclusion that a country in which land is relatively scarce will not be the country witha comparative advantage in the land-intensive product?Answer: The answer here is straightforward (though it has various interesting implications).In this case we cannot define or identify a product in terms of its relative factorintensity (at all or any relative wage level). Therefore, the Heckscher-Ohlin Theoremis ipso-facto inapplicable.3. Why is it that North-South trade in manufactures seems to be consistent with the results orexpectations generated by the factor-proportions theory of international trade, whereas North-North trade is not?Answer: There is a clear difference in relative factor availabilities between North and South countries, no matter how we define and measure the factors of production. Hence,the factor-proportions theory of trade may be sensibly expected to explain the pattern(though not the volume) of trade between these two groups of countries. However,the North North trade partners do not vary significantly in their relative factoravailabilities, so that other forces, such as scale economies play a relatively largerole in determining trade patterns.4. One of the commonly used assumptions in deriving the Heckscher-Ohlin model is that tastesare homothetic, or that if the per capita incomes were the same in two countries, theproportions of their expenditures allocated to each product would be the same as it is in theother country. Imagine that this assumption is false, and that in fact, the tastes in each country are strongly biased in favor of the product in which it has a comparative advantage. Howwould this affect the relationship between relative factor abundance between the two countries, and the nature (factor-intensity) of the product each exports? What if the taste bias favored the imported good?Answer: If in fact national tastes were strongly biased in favor of the product in which the country enjoyed a comparative advantage, then we would expect a bias in favor ofrejecting the Heckscher-Ohlin Theorem in actual trade data. The engine driving theH-O model is that a country should be expected to have a relatively low cost ofproducing the good in which it has a comparative advantage. However, therespective demand forces would tend to raise the price of this good, so that theexpected pattern would not generally be observed. However, if the tastes were biasedin favor of the imported good, then the predictions of the Heckscher-Ohlin Theoremwould be expected to be generally observed.5. Why do you suppose that South-South trade does not conform in volume, but does conform inpattern with expectations generated by the Heckscher-Ohlin model?Answer: The pattern of trade is generally observed to conform to the Heckscher-Ohlin models expectations. That is, the developing countries tend to export labor-intensive goods,such as textiles, and import capital-intensive goods such as machinery. The volumehowever is quite lower than what would be expected from the Neoclassical model.There are many possible reasons, such as financial crises necessitating premia in thefinancing of this trade.6. It has been argued that even if intra-European Union labor mobility were to be completelyremoved, one should not expect to observe massive, or even large reallocations of populations with the E.U. DiscussAnswer: Theoretically, just as completely free trade consistent with Heckscher-Ohlin model (with no complete specialization) is associated with factor price equalization; so doescompletely free labor mobility. It therefore follows that if intra E.U. trade flourishes,as any restraints on trade there are abolished, the economic incentive for labormobility will be removed. Since language and cultural differences remain, we wouldexpect populations to tend to stay where they are.Quantitative/Graphing Problems1. In Home and Foreign there are two factors of production, land and labor, used to produce onlyone good. The land supply in each country and the technology of production are exactly the same. The marginal product of labor in each country depends on employment as follows:Number of Workers Employed Marginal Product of Last Worker1 302 293 284 275 266 257 248 239 2210 2111 20Initially there are 11 workers employed in Home but only 3 workers in Foreign. Find the effect of free movement of labor from the high wage to the low wage country. When such economic migration ceases, what will be the levels of production, real wages and the income oflandowners in each country?Answer: The total production in the world will increase, since the addition to production (the marginal product of labor) in the target country is larger for each worker than theloss of production (also the marginal product of workers) in the emigration country.The real wages will rise in the emigration country and fall in the immigrationcountry. Landlord incomes will rise in the immigration country and fall in theemigration country.2. Suppose Australia, a land (K)-abundant country and Sri-Lanka, a labor(L)-abundant countryboth produce labor and land intensive goods with the same technology. Following the logic of the Heckscher-Ohlin model from Chapter 4, what will be the incentive for migration once trade is established between these two countries? Now, suppose that a tariff by one country creates an incentive for labor migration. From which country to which country will be the migration?Explain how you arrived at your answer.Answer: Once trade is established, there is no longer any incentive for (economic-based) immigration, since the real wages will be equalized in both. If a tariff is establishedin Australia, then the price of the labor intensive good will be higher in Australia, aswill be the marginal product of labor and hence the real wage of workers there.Hence, workers will immigrate from Sri-Lanka to Australia until the two domesticprices are equalized.3. Use the diagram below derived from Figure 4-4 to identify the pre-trade situation for Australiaand Sri-Lanka, as discussed in question 2 above. Where on the K/L axis will you find each of the two countries? Which of the two countries has a higher relative wage, w/r? Which product is the labor intensive, and which is the land intensive one? Show where the relative price of cloth to food will be found once trade opens between these two countries. Show where therelative wages of each will appear.Answer: You will find Sri-Lanka to the left of Australia on the K/L axis.Australia has a higher relative wage.Food is the land intensive product.The relative price P C/P F is found between the two autarkic prices.The post trade relative wage is between the two autarkic ones on the vertical axis. 4. Using the figure above from question 3, demonstrate what happens to the composition ofproduction (that is quantity of cloth per 1 unit of food) in Australia once trade is established between the two countries. Which country will export cloth? What happens to the relativeincome of workers in Australia as a result of trade? Does it increase or decrease? Would land owners in Australia lobby for or against free trade? Would land owners in Australia lobby for or against free admittance of immigrant workers?Answer: The proportion of food to cloth will increase in the production of Australia Sri Lanka will export cloth. The relative (and real) incomes of workers will fall in Australia asa result of trade. Land Owners in Australia should lobby in favor of trade. Theywould also lobby for free labor mobility (of workers into Australia), since themarginal product of labor is high, the owners of land have much (Ricardian) rents togain from an inflow of workers.5. Imagine that the relative capital abundance of Australia was so much greater than that of Sri-Lanka, that we would have to locate Australia far to the right on the K/L axis. If this were so far to the right that there was no area of overlap on the w/r axis, then what product wouldAustralia export? Is this answer different from that in question 4 above? Will the relativewages as calculated now be the same or different from those calculated in question 4?Answer: Australia would still export food, which is the same as in question 4. As a result of trade, wages will fall in Australia and will rise in Sri-Lanka. However, in this case,the wages in Australia will remain higher than in Sri-Lanka, creating an incentive formigration from the latter to the former country.。
