All rights reserved. 4-3 Heckscher-Ohlin (HO) Trade Model A country’s comparative advantage lies in production of goods that intensively use relatively abundant factors –Factor abundance: relative abundance of a factor, and the factor’s relative cost is less –Relatively scarce resources are more expensive

5. Copyright © 2011 Pearson Addison-Wesley. All rights reserved. 4-5 Heckscher-Ohlin (HO) Trade Model The U.S. is richly endowed with a wide variety of factors: natural resources, skilled labor, and physical capital U.S. will export agricultural goods, machinery, scientific and engineering goods

6. Copyright © 2011 Pearson Addison-Wesley. All rights reserved. 4-6 Gains from Trade in the HO Model Ricardian model: constant set of tradeoffs (costs) –One homogeneous input: labor The HO model: (1) multiple inputs—labor capital, land, etc.—and (2) variations in the quality of inputs PPC under the HO model –As produce more of one good, opportunity costs increases

7. Copyright © 2011 Pearson Addison-Wesley. All rights reserved. 4-7 Trade and Income Distribution The HO model: –Labor can be divided into categories of different skill levels –Other types of inputs can be included –Industries can require different mixes of various inputs Systematic relationship between the factor endowments of a country and the winners and losers from trade

8. Copyright © 2011 Pearson Addison-Wesley. All rights reserved. 4-8 The Stolper-Samuelson Theorem Assumptions: –Labor earns wages proportionate to its skill level –Owners of capital earn profits –Landowners earn rents –The amount of income earned per unit of input depends on both the demand (derived demand) for inputs and the supply of inputs Price of exported good rises, price of imported good falls

9. Copyright © 2011 Pearson Addison-Wesley. All rights reserved. 4-9 The Stolper-Samuelson Theorem An increase in the price of a good raises the income earned by factors that are used intensively in its production (exports) A fall in the price of a good lowers the income of the factors used intensively in its production (imports)

10. Copyright © 2011 Pearson Addison-Wesley. All rights reserved. 4-10 The Stolper-Samuelson Theorem Not all factors in the export industries will be better off, and not all factors used in import competing industries get hurt Abundant factors will benefit, while scarce ones will be hurt Magnification Effect: the change in output prices has a magnified effect on incomes.

11. Copyright © 2011 Pearson Addison-Wesley. All rights reserved. 4-11 The Stolper-Samuelson Theorem Ultimately, the effects on income of an opening of trade depends on the flexibility of the affected factors More flexible the resources are to adjust, the less hurt they are.

12. Copyright © 2011 Pearson Addison-Wesley. All rights reserved. 4-12 Specific Factors Model The HO model assumes that factors are mobile The Specific Factors model assumes: –(1) land and capital are immobile and cannot migrate (specific factors) –(2) labor is fully mobile and can migrate from one sector to another (variable factor)

13. Copyright © 2011 Pearson Addison-Wesley. All rights reserved. 4-13 Specific Factors Model Endowment of specific factor plays a more critical role in determining comparative advantage –When trade opens, incomes rise for the owners of the abundant specific factor –Incomes decrease for specific factor in shrinking industry –Effect on labor is indeterminant –Prices in exporting industry rise, prices in importing industry fall

All rights reserved. 4-24 OLI Theory OLI theory (Ownership-Location- Internalization) –Firms investing abroad own an asset that gives them a competitive advantage (Ownership) –Firms seek a production location that offers them advantages (Location) –Firms try to internally capture the advantages of foreign asset ownership (Internalization)

Productivity increases enable greater share of value-added output with smaller share of employment Motivation to off-shore is access to market and produce specialized products not to escape regulations or find low wages Most off-shoring occurs in high income, high wage economies
