Free trade is the idea that free market forces should determine how much to trade
with little or no government intervention.
Modern trade theories are the major theories of international trade that were
advanced in the 20th century, which consist of (1) product life cycle, (2) strategic
trade, and (3) national competitive advantage of industries.
Opportunity cost is the cost of pursuing one activity at the expense of another
activity, given the alternatives (other opportunities).
Product life cycle theory is a theory that accounts for changes in the patterns of
trade over time by focusing on product life cycles.
Protectionism is the idea that governments should actively protect domestic
industries from imports and vigorously promote exports.
Resource mobility is an assumption that a resource used in producing a product for
one industry can be shifted and put to use in another industry.
Strategic trade policy is a government policy that provides companies a strategic
advantage in international trade through subsidies and other supports.
Strategic trade theory is a theory that suggests that strategic intervention by
governments in certain industries can enhance their odds for international success.
Theory of absolute advantage is a theory that suggests that under free trade, a
nation gains by specializing in economic activities in which it has an absolute
advantage.
Theory of comparative advantage is a theory that focuses on the relative (not
absolute) advantage in one economic activity that one nation enjoys in comparison
with other nations.
Theory of mercantilism is a theory that suggests that the wealth of the world is
fixed and that a nation that exports more and imports less will be richer.
Theory of national competitive advantage of industries is a theory that suggests
that the competitive advantage of certain industries in different nations depends on
four aspects that form a “diamond.” Also known as the diamond theory.
III. REALITIES OF INTERNATIONAL TRADE
1. Key Concepts
The net impact of various tariffs and nontariff barriers (NTBs) is that the whole nation is
worse off while certain special interest groups (such as certain industries, firms, and
regions) benefit. Economic arguments against free trade center on (1) protectionism and
(2) infant industries. Political arguments against free trade focus on (1) national security,
(2) consumer protection, (3) foreign policy, and (4) environmental and social
responsibility.
Key Terms
Administrative policy is bureaucratic rules that make it harder to import foreign
goods.
Antidumping duty is a tariff levied on imports that have been “dumped” (selling
below costs to “unfairly” drive domestic firms out of business).
Deadweight cost is net losses that occur in an economy as a result of tariffs.
Import quota is restrictions on the quantity of imports.
Import tariff is a tax imposed on imports.
