Chapter 4;Introduction A Model of a Two-Factor Economy Effects of International Trade Between Two-Factor Economies Empirical Evidence on the Heckscher-Ohlin Model Summary Appendix: Factor Prices, Goods Prices, and Input Choices ;Introduction;Assumptions of the Model An economy can produce two goods, cloth and food. The production of these goods requires two inputs that are in limited supply; labor (L) and land (T). Production of food is land-intensive and production of cloth is labor-intensive in both countries. Perfect competition prevails in all markets. ;//;Factor Intensity In a world of two goods (cloth and food) and two factors (labor and land), food production is land-intensive, if at any given wage-rental ratio the land-labor ratio used in the production of food is greater than that used in the production of cloth: TF/LF TC/ LC Example: If food production uses 80 workers and 200 acres, while cloth production uses 20 workers and 20 acres, then food production is land-intensive and cloth production is labor-intensive. ;CC;Factor Prices and Goods Prices Stolper-Samuelson Theorem (effect): If the relative price of a good increases, holding factor supplies constant, then the nominal and real return (in terms of both goods) to the factor used intensively in the production of that good increases, while the nominal and real return (in terms of both goods) to the other factor decreases. The reverse is also true. ;SS;FF;An increase in the price of cloth relative to that of food, PC/PF ,will: Raise the income of workers relative to that of landowners, w/r. Raise the ratio of land to labor, T/L, in both cloth and food production and thus raise the marginal product of labor in terms of both goods. Raise the purchasing power of workers and lower the purchasing power of landowners, by raising real wages and lowering real rents in terms of both goods.;Resources and Output How is the allocation of resources determined? Given the relative price of cloth and the su
