They often despair of even trying to attempt to build their industries unless it is done in an autarkic

42、 context, behind protectionist walls because they do not believe they can compete with more productive industries abroad. Discuss this issue in the context of the Ricardian model of comparative advantage.In 1975, wage levels in South Korea were roughly 5% of those in the United States. It is obvious

43、 that if the United States had allowed Korean goods to be freely imported into the United States at that time, this would have caused devastation to the standard of living in the United States.,because no producer in this country could possibly compete with such low wages. Discuss this assertion in

44、the context of the Ricardian model of comparative advantage.The evidence cited in the chapter using the examples of the East Asia New Industrializing Countries suggests that as international productivities converge, so do international wage levels. Why do you suppose this happened for the East Asian

45、 NICs? In light of your answer, what do you think is likely to happen to the relative wages (relative to those in the United States) of China in the coming decade? Explain your reasoning.When we examine the 2 Good 2 Country version of the Ricardian model of comparative advantage, we note that compar

46、ative advantage is totally determined by physical productivity ratios. Changes in wage rates in either country cannot affect these physically determined comparative advantages, and hence cannot affect, which product will be exported by which country. However, when more than 2 goods are added to the

47、model (still with 2 countries), changes in wage rates in one or the other country can in fact determine which good or goods each of the countries will export. How can you explain this anomaly?An examination of the Ricardian model of comparative advantage yields the clear result that trade is (potent

48、ially) beneficial for each of the two trading partners since it allows for an expanded consumption choice for each. However, for the world as a whole the expansion of production of one product must involve a decrease in the availability of the other, so that it is not clear that trade is better for

49、the world as a whole as compared to an initial situation of non-trade (but efficient production in each country). Are there in fact gains from trade for the world as a whole? Explain.Quantitative/Graphing Problems1.Given the following information: Unit Labor Requirements Cloth WidgetsHome 100 200For

53、 60 30If these two countries trade these two goods with each other in the following the Ricardian model of comparative advantage, then what is the lower limit for the world equilibrium price of cloth?1. Home has 1200 units of labor available. It can produce two goods, apples and bananas. The unit la

54、bor requirement in apple production is 3, while in banana production it is 2.a. Graph Homes production possibility frontier.b. What is the opportunity cost of apples in terms of bananas?c. In the absence of trade, what would the price of apples in terms of bananas be? Why?2. Home is as described in

55、problem 1. There is now also another country, Foreign, with a labor force of 800. Foreigns unit labor requirement in apple production is 5, while in banana production it is 1.a. Graph Foreigns production possibility frontier.b. Construct the world relative supply curve.3. Now suppose world relative

56、demand takes the following form: Demand for apples / demand for bananas = price of bananas / price of applesa. Graph the relative demand curve along with the relative supply curve.b. What is the equilibrium relative price of apples?c. Describe the pattern of trade.d. Show that both Home and Foreign

57、gain from trade.4. Suppose that instead of 1200 workers, Home had 2400. Find the equilibrium relative price. What can you say about the efficiency of world production and the division of the gains from trade between Home and Foreign in this case? 5. Suppose that Home has 2400 workers, but they are o

58、nly half as productive in both industries as we have been assuming. Construct the world relative supply curve and determine the equilibrium relative price. How do the gains from trade compare with those in the case described in problem 4?6. “ Korean workers earn only $2.50 an hour; if we allow Korea

59、 to export as much as it likes to the United States, our workers will be forced down to the same level. You cant import a $5 shirt without importing the $2.50 wage that goes with it.” Discuss.7. 请对下列观点加以评价：（1）只有当一个国家的生产率达到足以在国际竞争中立足的水平时，它才能从自由贸易中获益；（2）如果来自外国的竞争是建立在低工资的基础上，那么这种竞争是不公平的，而且会损害其他参与竞争的国家；

60、（3）如果一个国家的工人比其他国家工人的工资低，那么贸易就会使这个国家受到剥削并使福利恶化。用标准的李嘉图假设，分析如下模型： 表1 单位产品劳动投入奶酪葡萄酒本国aLC = 10小时/磅aLW = 15小时/加仑外国aLC * = 4小时/磅aLW * = 10小时/加仑假设本国共拥有3000万工时的劳动量，而外国共有2000万工时的劳动量。哪个国家在葡萄酒的生产上具有绝对优势？哪个国家在奶酪的生产上具有绝对优势？哪个国家在葡萄酒的生产上具有比较优势？哪个国家在奶酪的生产上具有比较优势？在开放贸易后，两个国家各出口何种商品？如果均衡国际价格比率是每磅奶酪 1/2 瓶葡萄酒，各国的生产会发生什
