  5. International Trade & the World Economy;  Charles van Marrewijk Heckscher - Ohlin Heckscher-Ohlin proposition In a neo-classical framework with 2 final goods, 2 factors of production, and 2 countries which have identical homothetic tastes, a country will export the good which intensively uses the relatively abundant factor of production. If the production of manufactures is capital intensive and Austria is capital abundant, Austria will export manufactures and import food.

  7. International Trade & the World Economy;  Charles van Marrewijk Maximizing the utility function subject to a standard budget contraint implies that consumers will spent a fraction of their income on manufactures (quite similar to cost minimization problem for producers) Demand All previous neo-classical results depend only on the supply side, since we have to specify the demand side to make conclusions about trade flows.

  9. International Trade & the World Economy;  Charles van Marrewijk The production possibility frontier With crs and 2 factors of production the ppf is concave to the origin

  10. International Trade & the World Economy;  Charles van Marrewijk The production possibility frontier The curvature of the ppf depends on the difference in capital intensity for the production of food and manufactures

  11. International Trade & the World Economy;  Charles van Marrewijk The production possibility frontier Increase in capital stock leads to outward shift of ppf biased in the direction of capital intensive manufactures; tangency points at constant prices is straight line (Ryb)

  15. International Trade & the World Economy;  Charles van Marrewijk Autarky equilibrium

  16. International Trade & the World Economy;  Charles van Marrewijk Autarky equilibrium Capital abundant A produces relatively more capital intensive manufactures at relatively lower price Autarky in 2 countries (A and B)

  18. International Trade & the World Economy;  Charles van Marrewijk International trade equilibrium For A price of manufactures rises: capital abundant A produces even more capital intensive manufactures and exports these in exchange for food

  23. International Trade & the World Economy;  Charles van Marrewijk The case of the missing trade • First important empirical study (1956) leads to ‘Leontief paradox’: supposedly capital abundant USA imports capital intensive goods? • Possible explanations: demand bias, factor-intensity reversal, restrictiveness of 22 2 framework. • Later studies, e.g. Bowen, Leamer, and Sveikauskas (1987), analyze more goods, more factors, more countries, as did Trefler (1995) who • finds modest support for neo-classical trade model (about 71%) • shows that factor service trade is smaller than factor endowments prediction (case of missing trade) • support increases if technological differences (part I of the book) are taken into consideration (to about 78%) • support increases if domestic demand bias is taken into consideration (to about 87%) • with neo-classical model, different technology, and demand bias about 93% of international trade flows can be explained.

  25. International Trade & the World Economy;  Charles van Marrewijk Conclusions • Neo-classical model: • assumes identical homothetic preferences; neutralize demand effects • countries with high capital-labor ratio have high wage-rental ratio in autarky and low relative price of capital intensive good • free trade equalizes final goods prices (and thus factor prices; FPE) • capital abundant country exports capital intensive good (HOS) • free trade increases production, global efficiency, and welfare • extended version of the model performs reasonably well empirically • technology intensive manufacturing exports mainly in OECD countries (next slide)
