With trade, two nations’ common slope of production frontier and indifference curve gives the ( ) equilibrium-relative price.A. externalB. internationalC. internal4. The ( ) supply of a commodity above the no-trade equilibrium price gives one nation’s export supply of the commodity.A. domesticB. excessC. foreign5. The H-O theory is based on a number of simplifying assumptions including ( ).A. perfect competition in factor marketB. decreasing returns to scaleC. international mobility of factors6. Intra-industry trade arises in order to take advantage of important ( ) in production.A. factor abundanceB. domestic protectionC. economies of scale7.

When a large nation imposes an import tariff, the nation as a whole faces ( ) world price since the nation itself collects the amount of the tariff.A. an unchangedB. a higherC. a lower9. An import quota is in general ( ) an equivalent import tariff.A. less restrictive thanB. as the same restrictive asC. more restrictive than10. Trade diversion occurs when lower-cost imports from outside the customs union are replaced by higher-cost imports from ( ).A. outside the nationB. another union memberC. NAFTAⅡ.Write “T”for true and “F”for false. (2×10 points)1. In the absence of trade, a nation’s possibility frontier is also its consumption frontier. ( )2. With increasing cost, specialization in production is complete in a small country after trade.3. The offer curve of each nation bends towards the axis measuring the commodity of its comparative advantage. ( )4. Nation 2 is the K-abundant nation if the relative price of capital (r/w) is higherthan nation 1. ( )5. Economies of scale result when each firm or plant produces many styles or varieties of a product. ( )6. Production is protrade if the output of the nation’s exportable commodity increases proportionately more than output of its importable commodity. ( )7. When a small nation imposes an import tariff, its offer curve rotates toward the axis measuring its exportable commodity by the full amount of the tariff. ( )8. The commodity terms of trade measure the movement over time in the nation’s export prices relative to its import prices. ( )9. International capital transfers increase the national income both investing and host countries, but in the investing nation the relative share going to capital falls and the share going to labor rises. ( )10. International direct investments are usually undertaken by multinational corporations. ( )Ⅲ.Explain the following key terms. (4×5 points)1.Marginal rate of transformation2. External economies3. Stolper-Samuelson theorem4. Strategic trade policy5. Transfer pricingⅣ.Answer the following questions. (10×4 points)1. Nation 1 can produce 4 units commodity X or 1 unit commodity Y with all itsresources. Nation 2 can produce 1 unit commodity X or 2 units commodity Y with all its resources. (a) Please indicate the commodity in which each nation has a comparative advantage. (b) With constant opportunity cost, please draw the production frontiers of each nation. (c) Assume that two nations have the same tastes that both nations consumes X and Y in the same proportion (1unit X combining 1 unit Y), please calculate and show graphically for each nation the autarky point of production and consumption. (d) Assume that with the opening of trade nation 1 exchanges 1X for 1Y with nation 2, please calculate and show graphically for each nation the point of production and consumption with trade, and gains from trade.2. On one set of axes for nation 1, sketch a community indifferernce curve tangent to the fairly flat section of a concave production frontier skewed toward X axes. On a second set of axis for nation 2, sketch another (different) community indifferernce curve tangent to the fairly steep portion of a concave production frontier skewed toward Y axes. (a) Show on the diagrams the process of specialization in the production, the amount traded, and the gains from trade in each nation. (b) Write the equilibrium condition equations with trade. (c) Derive the offer curves for two nations from your diagrams.3. We assume that the H-O model holds and nation 2 is small country. We also assume that nation 2 is the K-abundant nation and commodity Y is the K-intensive commodity. Starting with nation 2’s pregrowth production frontier,draw a production frontier for nation 2 showing neutral technical progress that doubles the productivity of labor and capital in the production of: (a) Both commodity X and commodity Y. What is the volume of trade effect of growth? What is the wealth effect of growth? (b) Commodity X Only. What is the volume of trade effect of growth? What is the wealth effect of growth? (c) Commodity Y Only. what is the volume of trade effect of growth? What is the wealth effect of growth?4. Calculate the rate of effective protection (g) when the nominal tariff on the final commodity (t) is 30%, the ratio of the cost of the imported input to the price of the final commodity in the absence of tariffs (ai) is 0.6,and the nominal tariff on the imported input (ti) is 5o%. recalculate g with the following values of : (a) ti =30%. (b) ti =10%. What general conclusion can you reach about relationship between g and ti from your answer to above problems?Additional Questions (15×2 points)1. Assume that nation 1 is the L-abundant nation and commodity X is the L-intensive commodity. Derive the Edgeworth box diagram and , from it, the production frontier of nation 1.2. Give a graphical interpretation of the Hicksian classification of neutral, L-saving, and K-saving technical progress using isoquants. Examine the effect of the various types of technical progress on relative factor price.。
