Answer: A Question Status: New13) It has been argued that even if intra-European Union labor mobility were to be completely removed, one should not expect to observ

16、e massive, or even large reallocations of populations with the E.U. Discuss. Answer: Theoretically, just as completely free trade consistent with Heckscher-Ohlin model (with no complete specialization) is associated with factor price equalization; so does completely free labor mobility. It therefore

17、 follows that if intra E.U. trade flourishes, as any restraints on trade there are abolished, the economic incentive for labor mobility will be removed. Since language and cultural differences remain, we would expect populations to tend to stay where they are. Question Status: Previous Edition14) It

18、 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 un

19、it capital may be said to have a relative abundance of labor (or a comparative advantage in labor). They will therefore export their labor. Turning to the Neo-Classical trade model, we know that a country that is relatively labor abundant will export products (and enjoy comparative advantage) in pro

20、ducts that embody relatively more labor. Hence, trade exports labor indirectly embodied in products. This allows the workers to raise their real wage instead of doing it by physically moving to the capital rich country. Question Status: New15) It may be argued that, although theoretically internatio

21、nal labor mobility and international trade may be substitutes 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

22、 with large populations of Irish descent. Alternatively, one finds sales of imported Indian foods in specialized restaurants in areas with relatively large populations of immigrants from India. Or Mexican beer in areas with large or rapidly expanding populations from Mexico. This may easily be expla

23、ined by the Home good taste bias of populations. Along with international labor migrations come their tastes in foods as well as other products. Question Status: New16) One concomitant of international labor mobility is the phenomenon known as the brain drain. This refers to the immigration (or emig

24、ration) of the best and brightest. Generally countries tend to encourage such immigration. 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 t

25、han the average product in the host country. The host country reaps the benefits of education expended by other countries educational infrastructures. The answer to the second question is more difficult. An example is that during 2000, the Prime Minister of India lobbied for a change in U.S. immigra

26、tion laws so as to encourage the employment of more Indian engineers and computer programmers in the U.S. The answer to this seemingly paradoxical action may be related to the observed complementarity of international labor mobility and international trade. The presence of Indian engineers in the U.

27、S. may actually encourage the importation of Indian products and services in the computer field. Question Status: New 17) 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 exact

28、ly the same. The marginal product 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 free movement of labor from the high wage to the low wage country. When such economic migration ceases, what w

29、ill 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 ma

30、rginal product of workers) in the emigration country. The real wages will rise in the emigration country and fall in the immigration country. Landlord incomes will rise in the immigration country and fall in the emigration country. Question Status: Previous Edition18) Suppose Australia, a land (K)-a

31、bundant country and Sri-Lanka, a labor(L)-abundant country both 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, suppo

32、se 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

33、 be equalized in both. If a tariff is established in 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 domestic

34、prices are equalized. Question Status: Previous Edition7.2 International Borrowing and Lending1) International borrowing and lending may be interpreted as one form of A) intermediate trade.
