39、 none of the above.answer: d?essay questions1.the heckscher-ohlin model is famous for being elegant and mathematically sophisticated, yetfailing to describe reality. one manifestation of this fact is treflers case of missing trade.explain what exactly is missing. in what sense is it missing? how wou

40、ld you explain why it ismissing? how can a relaxation of the identical production functions explain the case of themissing trade?answer:answer: trefler demonstrated that the actual volume of world trade is significantly less thanthat which would be predicted by the heckscher-ohlin model. one explana

41、tion 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 still behigher than the cost of produ

42、cing it in the other country.2.factor-intensity reversalsdescribe a situation in which the production of a product may beland-intensive in one country, and relatively labor intensive in another (at given relative wagelevels). for example, cotton may be land intensive in the u.s., and labor intensive

43、 in egyptwhere land is relatively scarce and expensive. suppose factor-intensity reversalswere common.how would that 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:answer: the answer here

44、 is straightforward (though it has various interesting implications). inthis case we cannot define or identify a product in terms of its relative factor intensity(at all or any relative wage level). therefore, the heckscher-ohlin theorem is ipso-facto inapplicable.3.why is it that north-south trade

45、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 southcountries, no matter how we define a

46、nd 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 factoravailabil

47、ities, so that other forces, such as scale economies play a relatively large rolein 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 o

48、f 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 countryare strongly biased in favor of the product in which it has a comparative advantage. howwould this affect the relationship

49、 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:answer: if in fact national tastes were strongly biased in favor of the product in which thecountry enjoyed a comparative

50、 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 respectivedeman

51、d 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 s

52、outh-south trade does not conform in volume, but does conformin pattern with expectations generated by the heckscher-ohlin model?answer:answer: the pattern of trade is generally observed to conform to the heckscher-ohlinmodels expectations. that is, the developing countries tend to export labor-inte

53、nsivegoods, such as textiles, and import capital-intensive goods such as machinery. thevolume however is quite lower than what would be expected from the neoclassicalmodel. there are many possible reasons, such as financial crises necessitating premiain the financing of this trade.6.it has been argu

54、ed that even if intra-european union labor mobility were to be completelyremoved, one should not expect to observe massive, or even large reallocations of populationswith the e.u. discussanswer: theoretically, just as completely free trade consistent with heckscher-ohlin model(with no complete speci

55、alization) 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 r

56、emain, we wouldexpect populations to tend to stay where they are.?quantitative/graphing problems?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

57、 exactlythe same. the marginal product of labor in each country depends on employment as follows:number of workersnumber of workersemployedemployedmarginal productmarginal productof last workerof last worker 130 229 328 427 526 625 724 823 92210211120initially there are 11 workers employed in home b

58、ut only 3 workers in foreign. find the effectof free movement of labor from the high wage to the low wage country. when such economicmigration 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

59、, since the addition to production (themarginal product of labor) in the target country is larger for each worker than the lossof production (also the marginal product of workers) in the emigration country. thereal wages will rise in the emigration country and fall in the immigration country.landlor

60、d incomes will rise in the immigration country and fall in the emigrationcountry.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 ofthe heckscher-ohlin model from chapt
