3. WHY DO COUNTRIES TRADE ?
1. Availability of products (natural
resources, new products, etc.)
2. International price differential as
a consequence of:
Productivity differential
Differences in technology
Differences in factor endowments
Economies of scale
3. Product differentiation and market
structure

4. WHAT IS TRADE THEORY
Exchange of raw
materials and
manufactured goods
(and services) across
national borders
Trade Theory-Global Business Management 4
5. MERCANTILISM THEORY
The theory that a country’s power depended mainly
on its wealth to build strong navies and purchase vital
trade goods
Trade Theory-Global Business Management 5
6. MERCANTILISM THEORY
In 17th century group of men (merchants,
bankers, government officials & philosophers)
wrote essays on international trade that
advocated an economic philosophy known as
Mercantilism
In their view, a country becomes rich if it exports
more than it imports
Surplus in trade balance will result in an inflow
of precious metals; gold and silver
More precious metals means a richer and more
powerful nation
Countries have to do their best to increase
exports and restrict imports.
Trade Theory-Global Business Management 6
7. CONTD..
Since all countries cannot have surplus at the same time &
because stock of metals is fixed in short run, a country gains
from trade only at expense of others
Wealth of nations was measured by stock of metals they
possess
In contrast, today we measure wealth of a nation by its stock
of human, man-made & natural resources available for
producing goods & services
Mercantilists advocated strict government control of
economic activity because gain from trade comes at expense
of other nations (i.e. zero-sum-game)

11. ABSOLUTE ADVANTAGE
THEORY
Adam Smith: Wealth of Nations (1776)
argued:
Capability of one country to produce
more of a product with the same
amount of input than another country
A country should produce only goods
where it is most efficient, and trade for
those goods where it is not efficient
Trade between countries is, therefore,
beneficial
Assumes there is an absolute balance
among nations
Trade Theory-Global Business Management 11
14. COMPARATIVE
ADVANTAGE THEORY
David Ricardo: (1817) argued:
A country should produce only goods where
it is most efficient & import those goods in
which it’s less efficient
Even if a country is efficient in producing all the
goods, still trade between two countries will
prove beneficial
Assumes that a country does not have to be
best at anything to gain from trade
Country gains in those activities which it can
produce at world prices even though it may not
have absolute advantage
Trade Theory-Global Business Management 14
15. LIMITATIONS
• Ricardo's Theory was based on only two
countries & only two commodities, but
international trade is among many countries with
many commodities
• Assumption of full employment helps theory to
explain trade on the basis of comparative
advantage. Cost of production, even in terms of
labour, may change as countries, at different
levels of employment move towards full
employment
• Another serious defect is that transportation
costs are not considered in determining
comparative cost differences
• Ricardian theory is not applicable to developing
countries as these countries are nowhere near to
full employment
Trade Theory-Global Business Management 15
16. FACTOR ENDOWMENT
THEORY
Trade theory holding that countries
produce & export those goods that
require resources (factors) that are
abundant (and thus cheapest) &
import those goods that require
resources that are in short supply
Example:
Australia – lot of land and a small
population (relative to its size)
So what should it export and
import?
Trade Theory-Global Business Management 16
20. 4-20
•Trade theory holding that a country will
begin by exporting its product & later
undertake foreign direct investment as
product moves through its lifecycle
•As products mature, both location of
sales optimal production changes
•Affects direction & flow of imports &
exports
•Globalization & integration of economy
makes this theory less valid
PRODUCT LIFE CYCLE THEORY
( R .VERON ( 1966))
Trade Theory-Global Business Management
22. 4-22
•Increased emphasis on technology’s
impact on product cost
•Explained international investment
•Limitations
•Most appropriate for technology-based
products
•Some products not easily characterized by
stages of maturity
•Most relevant to products produced
through mass production

23. HECKSCHER OHLIN THEORY
Given by Filip Heckscher
Explained link between factor
endowments & comparative
advantage of nations
Country has comparative advantage in
those factors which make use of
abundant factor
Free trade equalizes factor prices
Trade gains are greatest between
countries with greatest difference in
economic structure

(1879-1952)

25. LEONTIEF PARADOX
Given by Wassily Leontief in 1973
Found out that U.S. exports were
apparently labour intensive & imports
capital intensive
Findings were contradictory to
predictions of Heckscher-Ohlin
theorem
Stimulated enormous amount of
empirical & theoretical research on
subject

27. PORTER’S DIAMOND
MODEL
Developed by Michael Porter in his
book ‘The Competitive Advantage of
Nations’
Explains why particular industries
become competitive in particular
locations
Competitiveness of one company is
related to the performance of other
companies
Demand, factor conditions,
government policies help companies
create competitive advantageTrade Theory-Global Business Management 27
29. NEW TRADE THEORY
Collection of economic models in
International trade which focuses on role of
increasing returns to scale
This theory relaxed the assumption of
constant returns to scale
Emphasized firm level differences in same
industry of the same country
Also emphasized the growing trend of
intermediate goods
Assumed that all firms are symmetrical,
meaning they have the same production
