different factor endowments. But intraindustry trade means the flows of goods with similar factor requirements, nations that are exporters of manufactured goods embodying sophisticated technology also purchase such goods from other nations. Intraindustry trade includes trade in homogeneous goods as well as in differentiated products, and intraindustry trade increases the range of choices available to consumers as well as the degree of petition 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 . (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 ’s parative advantage goods, because is abundant in skilled labor resources, so demand curve of skilled labor increased from D0 to D1, so wage ratio increased to , 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(), the wage ratio increased to wage inequality also bee 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(), the wage ratio decreased to , the wage inequality is smaller than before. For , a better solution involves better education and increased training to allow lowwage workers to take advantage of the technological changes that increase productivity.
