The Leontief paradox refers to the empirical finding that U.S. a. import substitutes are more L-intensive than exports b. imports are more K-intensive than exportsc. exports are more K-intensive than imports d. exports are more K-intensive than import substitutes23*. From empirical studies, we conclude that the H-O theory: a. must be rejected b. must be accepted without reservations c. can be accepted while awaiting further testing d. explains all international trade24.

U.S. tastes were biased strongly in favor of capital intensive goods d. The two factor model that was used was incomplete27. According to the factor price equalization theorem a nation that has a relative capital abundance should specialize in goods that are _ intensive resulting in an increase in the price of _. a. capital; capital b. capital; labor c. labor; capital d. labor; labor28. Which of the following theories is based on the demand conditions.a. Overlapping Demand Theory b. Comparative Advantage Theoryc. Product Life Cycle Theory d. H-O Theoryshort answers31. How does the H-O theory differ from Ricardo theory in explaining international trade patterns?Ricardo theory assumed only one factor (labor) ruled out the trade effects and explained that the difference of commodities prices is the reason why trade occurred, the H-O theory explained trade by differences in relative national supply conditions, even the theory highlights the role of nations resource endowment as the key determinant of comparative advantage. A nation will export that commodity for which a large amount of the relatively abundant input is used, it will import that commodity in the production of which the relatively scare input is used. 32. According to Staffan Linder, there are two explanations of international trade patternsone for manufactures and another for primary (agricultural) goods. Explain!Linder considered that the H-O theory has explanatory power for trade in primary goods, natural resources and agricultural goods, not for trade in manufactured goods, because the main force influencing manufactured good trade is domestic demand conditions. Based on similar preferences, wealthy nations will likely trade with other wealthy nations, and poor nations will likely trade with other poor nations. 33. How can economies of scale production affect world trade patterns?Economies of scale is that a large organization may reduce costs by specializing in machinery and labor, and under this condition the PPF shape is convex to origin.The countries with economies of scale refer to the production situation where output grows proportionately more than the increase in inputs or factors of production. That means the reduction in the average costs of production as the firms output expands, thus the nation can export this kind of commodity for its comparative advantage. 34. Distinguish between intra-industry trade and inter-industry trade, what are some major determinants of intra-industry trade?The inter-industry trade means the exchange between nations of products of different industries, it involves of different factor endowments. But intra-industry trade means the flows of goods with similar factor requirements, nations that are net exporters of manufactured goods embodying sophisticated technology also purchase such goods from other nations. Intra-industry trade includes trade in homogeneous goods as well as in differentiated products, and intra-industry trade increases the range of choices available to consumers as well as the degree of competition among manufactures of the same class of product in each nation. Essay 35. Try to draw the figure that vertical axis shows the wage ratio, which equals the wage of skilled workers divided by the wage of unskilled works; Horizontal axis shows that the labor ratio, which equals to the quantity of skilled workers available divided by the quantity of unskilled works. Suppose that supply curve of skilled workers relative to unskilled workers is fixed and denoted by S0, the demand curve for skilled workers relative to unskilled workers is denoted by D0. Explain that how the following three factors will affect wage inequality for U.S.(1) International trade and technological change(2) Immigration(3) Education and training (1) International trade and technological change will result an increase the demand of U.Ss comparative advantage goods, because U.S is abundant in skilled labor resources, so demand curve of skilled labor increased from D0 to D1, so wage ratio increased to 2.5, wage inequality is larger than before. (2) Immigration of unskilled labor results in a decrease in the sully of skilled labor relative to unskilled labor. So supply curve shifts from S0(2) to S2(1.5), the wage ratio increased to 2.5 wage inequality also become larger than before.(3) Education and training increased the number of skilled labor, and so the ratio of skilled labor to unskilled labor, as seen by the increase in the supply curve from S0(2) to S1(2.5), the wage ratio decreased t
