1 International Trade Theory
This is a test

2 International Trade Theory
What is international trade? Exchange of raw materials and manufactured goods (and services) across national borders Classical trade theories: explain national economy conditions--country advantages--that enable such exchange to happen New trade theories: explain links among natural country advantages, government action, and industry characteristics that enable such exchange to happen Implications for International Business

3 Classical Trade Theories
Mercantilism (pre-16th century) Takes an us-versus-them view of trade Other country’s gain is our country’s loss Free Trade theories Absolute Advantage (Adam Smith, 1776) Comparative Advantage (David Ricardo, 1817) Specialization of production and free flow of goods benefit all trading partners’ economies Free Trade refined Factor-proportions (Heckscher-Ohlin, 1919) International product life cycle (Ray Vernon, 1966)

4 The New Trade Theory As output expands with specialization, an industry’s ability to realize economies of scale increases and unit costs decrease Because of scale economies, world demand supports only a few firms in such industries (e.g., commercial aircraft, automobiles) Countries that had an early entrant to such an industry have an advantage: Fist-mover advantage Barrier to entry

5 New Trade Theory Global Strategic Rivalry
Firms gain competitive advantage trough: intellectual property, R&D, economies of scale and scope, experience National Competitive Advantage (Porter, 1990)

6 Mercantilism/Neomercantilism
Prevailed in Export more to “strangers” than we import to amass treasure, expand kingdom Zero-sum vs positive-sum game view of trade Government intervenes to achieve a surplus in exports King, exporters, domestic producers: happy Subjects: unhappy because domestic goods stay expensive and of limited variety Today neo-mercantilists = protectionists: some segments of society shielded short term

7 Absolute Advantage Adam Smith: The Wealth of Nations, 1776
Mercantilism weakens country in long run; enriches only a few A country Should specialize in production of and export products for which it has absolute advantage; import other products Has absolute advantage when it is more productive than another country in producing a particular product G Cocoa G: Ghana K: S. Korea K K' Rice G'


9 Comparative Advantage
David Ricardo: Principles of Political Economy, 1817 Country should specialize in the production of those goods in which it is relatively more productive... even if it has absolute advantage in all goods it produces Absolute Advantage is a special case of Comparative Advantage G Cocoa Example: Medical Specialist is also the best medical secretary. Should this doctor spend any time on the secretarial part of the business? No? Why? Lets continue with SL and the USA... This time the terms have changed to give the USA the absolute adv. in both tea and wheat... G: Ghana K: S. Korea K K' G' Rice


11 Heckscher (1919)-Ohlin (1933) Differences in factor endowments not on differences in productivity determine patterns of trade Absolute amounts of factor endowments matter Leontief paradox: US has relatively more abundant capital yet imports goods more capital intensive than those it exports Explanation(?): US has special advantage on producing new products made with innovative technologies These may be less capital intensive till they reach mass-production state

12 Theory of Relative Factor Endowments (Heckscher-Ohlin)
Factor endowments vary among countries Products differ according to the types of factors that they need as inputs A country has a comparative advantage in producing products that intensively use factors of production (resources) it has in abundance Factors of production: labor, capital, land, human resources, technology

13 International Product Life-Cycle (Vernon)
Most new products conceived / produced in the US in 20th century US firms kept production close to their market initially Aid decisions; minimize risk of new product introductions Demand not based on price; low product cost not an issue Limited initial demand in other advanced countries initially Exports more attractive than overseas production When demand increases in advanced countries, production follows With demand expansion in secondary markets Product becomes standardized production moves to low production cost areas Product now imported to US and to advanced countries


15 Classic Theory Conclusion
Free Trade expands the world “pie” for goods/services Theory Limitations: Simple world (two countries, two products) no transportation costs no price differences in resources resources immobile across countries constant returns to scale each country has a fixed stock of resources and no efficiency gains in resource use from trade full employment Real world: many countries and many goods Transportation costs may decline with specialization Prices in different countries can be (are) effected by exchange rates. Wheat and Tea are not necessarily a one-to-one swap resources can move from country to country: labor (Mexico to US), capital (constant returns to scale: specialization does not effect the amount of resources required to produce one ton of wheat or tea) both diminishing and increasing returns to specialization exist assumed fixed stock of resources in each country. Trade can change the efficiency with which the resources are used and the stock of resources may change too (more people, more natural resources, more efficient use due to technology) Full employment implies use of resources at full efficiency...

16 New Trade Theories Increasing returns of specialization due to economies of scale (unit costs of production decrease) First mover advantages (economies of scale such that barrier to entry crated for second or third company) Luck... first mover may be simply lucky. Government intervention: strategic trade policy Commercial jet industry: studies show that 3 major manufacturers can survive. Boeing, McDonnell Douglas and Airbus already there... New entries discouraged... however, the largest potential customer is China and they want the capacity to produce... hence the battle Boeing is having with unions... either give China some of the value added activity to keep them out of mainline or lose out to Airbus or to a non-economic decision to start an industry. Luck: DeHaviland in 50s. Comet fell out of sky. 707 captured the market. (some say it was not only luck but resources. B. had produced 707 on the back of technology developed for US military--spillover effect?? what of our claim that Airbus was subsidized??)

17 National Competitive Advantage (Porter, 1990)
Factor endowments land, labor, capital, workforce, infrastructure (some factors can be created...) Demand conditions large, sophisticated domestic consumer base: offers an innovation friendly environment and a testing ground Related and supporting industries local suppliers cluster around producers and add to innovation Firm strategy, structure, rivalry competition good, national governments can create conditions which facilitate and nurture such conditions Factor Endowments: basic factors: natural resources, climate, location, demographics advanced factors: communications infrastructure, sophisticated and skilled labor, R&D, technological know-how advanced factors are most important: they are the result of investment by individuals, companies and government (education, general skill and knowledge stimulation, basic R&D support) Demand conditions: sophisticated home demand can create impetus for enhancing competitive advantage (Japanese consumer knowledgeable on cameras pushed J. industry to create advantage) Related and Supporting industries: internationally competitive suppliers. Creation of clusters of related industries. ex. German textile and apparel sector (high qual. cotton, wool, synthetic fibers, sewing machine needles, textile machinery) Firm Strategy, Structure, and Rivalry within a nation: Management ideologies: predominance of engineers in TMTs of Germ. and J. cos. helped improve manufacturing processes and product designs (Porter found top execs with finance backgrounds in US 70s. most CEOs of the 40 companies I studies were marketing specialists). Vigorous domestic rivalry creates persistent comp. advantage in and industry: impr. efficiency and leads to international competitiveness.
