An Overview of Trade Theory
Free Trade occurs when a government does not
attempt to influence, through quotas or duties, what its
citizens can buy from another country or what they
can produce and sell to another country.
The Benefits of Trade allow a country to specialize
in the manufacture and export of products that can be
produced most efficiently in that country.
The Pattern of International Trade displays patterns
that are are easy to understand (Saudi Arabia/oil or
Mexico/labor intensive goods). Others are not so easy
to understand (Japan and cars).

Mercantilism: mid-16th century
A nation’s wealth depends on accumulated
treasure
Gold and silver are the currency
of trade.
Theory says you should have
a trade surplus.
Maximize exports through
subsidies.
Minimize imports through tariffs
and quotas.
Flaw: “Zero-sum game”.

David Hume - 1752
Increased exports leads to inflation and higher
prices.
Increased imports lead to lower prices.
Result: Country A sells less because of high
prices and Country B sells more because of lower
prices.
In the long run, no one can keep a trade surplus.

Theory of Absolute Advantage
Adam Smith: Wealth of Nations (1776).
Capability of one country to produce more of a product
with the same amount of input than another country.
Produce only goods where you are most efficient, trade for
those where you are not efficient.
Trade between countries is, therefore, beneficial.
Assumes there is an absolute advantage
balance among nations.

Theory of Comparative Advantage
David Ricardo: Principles of Political Economy
(1817).
Extends free trade argument
Efficiency of resource utilization leads to more productivity.
Should import even if country is more efficient in the
product’s production than country from which it is buying.
• Look to see how much more efficient. If only comparatively
efficient, than import.
Makes better use of resources
Trade is a positive-sum game.

require more resources.

Increase the efficiency of resource utilization.

Is the Mercantilist Theory Still
Valid?
A qualified Yes.

power and economic power with a trade

Heckscher (1919)-Olin (1933)
Theory
Export goods that intensively use factor
endowments which are locally abundant.
Corollary: import goods made from locally scarce
factors.
Patterns of trade are determined by differences in
factor endowments - not productivity.
Remember, focus on relative advantage, not
absolute advantage.

The Leontief Paradox, 1953
Disputes Heckscher-Olin in some instances.
Factor endowments can be impacted by
government policy - minimum wage.
US tends to export labor-intensive products,
but is regarded as a capital intensive country.

Heckscher vs Ricardo
Economists prefer Heckscher on theoretical
grounds but is a relatively poor predictor of
trade patterns.
Ricardo’s Comparative Advantage Theory,
regarded as too limited for predicting trade
patterns, actually predicts them with greater
accuracy.
In the end, differences in productivity may be
the key to determining trade patterns.

Product Life-Cycle Theory
(Raymond Vernon, 1966)
Article in the Quarterly Journal of Economics.
As products mature, both location of sales and
optimal production changes.
Affects the direction and flow of imports and
exports.
Globalization and integration of the economy makes
this theory less valid.

The New Trade Theory
Began to be recognized in the 1970s.
Deals with the returns on specialization
where substantial economies of scale are
present.
Specialization increases output, ability to
enhance economies of scale increase.

Application of the New Trade
Theory
Typically, requires industries with high, fixed
costs.
World demand will support few competitors.
Competitors may emerge because “they got
there first”.
first-mover advantage.
Some argue that it generates government
intervention and strategic trade policy.

Porter’s Diamond
(Harvard Business School, 1990)
The Competitive Advantage of Nations.
Looked at 100 industries in 10 nations.
Thought existing theories didn’t go far enough.
Question: “Why does a nation achieve
international success in a particular
industry?”

Determinants of National
Competitive Advantage
Factor endowments:nation’s position in factors of production
such as skilled labor or infrastructure necessary to compete in a
given industry.
Firm strategy, structure and rivalry:the conditions in the
nation governing how companies are created, organized, and
managed and the nature of domestic rivalry.
Demand conditions:the nature of home demand for the
industry’s product or service.
Related and supporting industries:the presence or absence
in a nation of supplier industries or related industries that are
nationally competitive.

success.

Factor Endowments
Taken from Heckscher-Olin
Basic factors:
natural resources,
climate,
location.
Advanced factors:
communications,
skilled labor,
technology.

Advanced Factor Endowments
More likely to lead to competitive
advantage.
Are the result of investment by
people, companies, government.

Relationship of Basic to
Advanced Factors
Basic can provide an initial advantage.
Must be supported by advanced factors to
maintain success.
No basics, then must invest in advanced
factors.

Evaluating Porter’s Theory
If Porter is right, country exports should
reflect the presence of the four ‘diamond’
components. Countries will import goods
from industries where some or all the
components are missing.

Implications for Business
Location implications:makes sense to disperse
production activities to countries where they can be
performed most efficiently.
First-mover implications:It pays to invest
substantial financial resources in building a firstmover, or early-mover, advantage.
Policy implications:promoting free trade is
generally in the best interests of the home-country,
although not always in the best interests of the firm.
Even though, many firms promote open markets.
