3ObjectivesDefine the term international trade and discuss the role of mercantilism in modern international trade.Contrast the theories of absolute advantage and comparative advantage.Relate the importance of international product life cycle theory to the study of international economics.Explain some of the most commonly used barriers to trade and other economic developments that affect international economics.Discuss some of the reasons for the tensions between the theory of free trade and the widespread practice of national trade barriers.
4IntroductionInternational trade: the branch of economics concerned with the exchange of goods and services with foreign countries.We will focus on:International trade theoryBarriers to trade.
6Why do nations trade? Trade theories: Mercantilism; theory of absolute advantage;theory of comparative advantage;factor endowment theory;international product cycle theory;other considerations.
7MercantilismA trade theory which holds that a government can improve the well-being of the country by encouraging exports and stifling imports.Cf.) Neo mercantilism: without the reliance on precious metal (gold).
8Theory of absolute advantage A trade theory which holds that by specializing in the production of goods, which they can produce more efficiently than any others, nations can increase their economic well-being.An exampleAssume:labour is the only cost of production;lower labour-hours per unit of production means lower production costs and higher productivity of labour.
9Theory of absolute advantage (Continued) North has an absolute advantage in the production of cloth.South has an absolute advantage in the production of grain.It follows that:If North produces cloth and South produces grain, and an exchange ratio can be arranged, both the countries will benefit from trade.
10Theory of comparative advantage A trade theory which holds that nations should produce those goods for which they have the greatest relative advantage.An exampleAssume:labour is the only cost of production;lower labour-hours per unit of production means lower production costs and higher productivity of labour.
11Theory of comparative advantage (Continued) North has an absolute advantage in the production of both cloth and grain but the relative costs differ (i.e. gains from trade).In North, one unit of cloth costs 50/100 hours of grain.In South, one unit of cloth costs 100/100 hours of grain.It follows that:If North can import more than a half unit of grain for one unit of cloth, it will gain from trade.If South can import one unit of cloth for less than one unit of grain, it will also gain from trade.Under the circumstance presented in the above example, both countries can benefit from trade.
12Factor endowment theory Also known as the Heckscher-Ohlin theory,It extends the concept of comparative advantage by bringing into consideration the endowment and cost of factors of production and helps to explain why nations with relatively large labour forces will concentrate on producing labour-intensive goods, whereas, countries with relatively more capital than labour will specialize in capital-intensive goods.Weaknesses of factor endowment theory:Some countries have minimum wage laws that result in high prices for relatively abundant labour.The Leontief paradox: countries like the United States actually export relatively more labour-intensive goods and import capital-intensive goods.No single theory can explain the role of economic factors in trade theory.
13International product life cycle theory (IPLC) A theory of the stages of production for a product with new “know-how”: it is first produced by the parent firm, then by its foreign subsidiaries and finally anywhere in the world where costs are the lowest; it helps to explain why a product that begins as a nation’s export often ends up as an import.

17Reasons for barriers to trade Protect local jobs by shielding home-country business from foreign competition.Encourage local production to replace imports.Protect infant industries that are just getting started.Reduce reliance on foreign suppliers.Encourage local and foreign direct investment.Reduce balance of payments problems.Promote export activity.Prevent foreign firms from dumping, that is, selling goods below cost in order to achieve market share.Promote political objectives such as refusing to trade with countries that practice apartheid or deny civil liberties to their citizens.
18Commonly used barriers to trade Price-based barriersTariffs: a tax on goods shipped internationallyQuantity limitsQuotas: a quantity limit on imported goodsEmbargos: a quota set to zeroInternational price fixingA cartel: a group of firms that collectively agree to fix prices or quantities sold in an effort to control priceNon-tariff barriersFinancial limitsExchange controls: controls that restrict the flow of currencyForeign investment controlsLimits on FDILimits on transfer or remittance of funds
19Types of tariffsImport and export tariffs: a tax levied on imports or exports of a country.Transit tariff: a tax levied on goods passing through the country.Specific duty: a tariff based on the number of items being imported.Ad valorem duty: a tariff based on a percentage of the value of imported goods.Compound duty: a tariff consisting of both a specific and ad valorem duty.
21Reasons for tariffsTo retaliate against dumping: the selling of goods at a price below cost or below that in the home country.To protect local industry.To raise revenue.To reduce foreign expenditures by citizens in order to improve the country’s balance of payments.
26Other economic developments Countertrade: barter trade in which the exporting firm receives payments in products from the importing country.Trade in services: as high-income countries move toward a service economy, trade in services has grown.Free trade zones: a designated area where importers can defer payment of customs duty while further processing of products takes place (as a foreign trade zone).
