CHAPTER 5
INTERNATIONAL TRADE
Case: Sri Lankan Trade
Since independence Sri Lanka has looked to international trade
policy as a means of helping to solve such problems as:
a) shortage of foreign exchange
b) overdependence on one product and one market
c) insufficient growth of output and employment
Import Substitution & Strategic Trade Policy
Development of exports of nontraditional Products
Identifying the most likely competitive Industries
Manufacturing has grown as a portion of total Exports
I - INTRODUCTION
Trade theory focuses on three basic questions:
a) What products to import and export?
b) How much to trade?, and
c) With whom to trade?
Some theories explain trade patterns that exist in the absence
of governmental interference, and some theories explain what governmental
actions should strive for in trade.
II - TRADE THEORY AND GOVERNMENT POLICY
A - Mercantilism: mid-16th century, principal assertion was that
gold and silver were the mainstays of national wealth and essential
to vigorous commerce.
Main tenant: it was in a country's best interest to maintain a
trade surplus, a country would increase its national wealth and
prestige
Autarky
Trade was viewed as a zero-sum-game
David-Hume
Neo-Mercantilism
B - Absolute Advantage: a country has an absolute advantage in
the production of a product when it is more efficient than any
other country in producing it. Countries should specialize in
the production of goods for which they have an absolute advantage
and then trade these goods for goods produced by other countries.
Basic Argument: you should never produce goods at home that you
can buy at lower cost form other countries.
Absolute advantage - exists potential for gains in trade
Adam Smith's 1776 "An Inquiry Into the Wealth of Nations."
Introduced the concept of specialization
Trade is not a zero-sum game situation
1. Natural Advantage: a country may have a natural advantage in
producing a product because of climatic conditions, access to
a certain natural resources, or availability of an abundant labour
force
2. Acquired Advantage: industrial policy
C - Comparative Advantage: In his 1817 book ôPrinciples
of Political Economyö, David Ricardo says that it makes sense
for a country to specialize in the production of those goods that
it produces most efficiently and to buy the goods that it produces
less efficiently from other countries, even if it could produce
them more efficiently itself. In other words, nations should produce
those goods for which they have the greatest relative advantage
According to David Ricardo potential world production is greater
with unrestricted free trade than it is with restricted trade.
Consumers in all countries can consume more if there are no restrictions
to trade.
Differences in labour productivity between nations underlie the
notion of comparative advantage
C.1. Simple Extensions of the Ricardian Model:
Diminishing Returns to Specialization: not all resources are of
the same quality, draw upon marginal resources whose productivity
is not as great as those initially employed
Dynamic Effect and Economic Growth: Free trade might increase
a country's stock of resources, free trade might also increase
the efficiency with which a country utilizes its resources
Dynamic gains in both the stock of a country's resources and the
efficiency with which resources are utilized will cause a country's
Production Possibility Frontiers (PPF) to shift outwards
C.2. Theory of Country Size: larger countries are more self-sufficient
C.3. Transportation Costs: make it more likely that small countries
will trade internationally
C.4. Scale Economies: countries with large economies and high
per capita income are more likely to produce goods that use technologies
requiring long production runs.
D - Heckscher-Ohlin Theory
Two swedish economists put forward a different explanation of
comparative advantage: they argued that comparative advantage
arises from differences in national factor endowments.
Different nations have different factor endowments and different
factor endowments explain differences in factor costs. The more
abundant a factor, the lower its cost.
This H-Ohlin theory predicts that countries will export those
goods that make intensive use of those factors that are locally
abundant, while importing goods that make intensive use of factors
that are locally scarce.
The Leontief Paradox: U.S. produces and exports technology intensive
products that require highly educated labor.
D - Product Life Cycle: Raymond Vernon proposed the PLC in the
early 1960s. Raymond argued that the size and the wealthy market
gave American companies a strong motivation to develop innovative
consumer goods.
As the market in the US and other more developed countries matures,
the products becomes more standardized, and price becomes the
main competitive factor.
Further along, the U.S. switches from being an exporter of the
product to an importer of the product as production becomes concentrated
in lower cost foreign locations.
Ex: cellular phones
PLC weakness
E - The New Trade Theory:
First Mover Advantages: the theory suggests that a country may
predominate in the export of a good simply because it was lucky
enough to have one or more firms among the first to produce that
good.
This theory generates an argument for government intervention,
industrial policy, and strategic trade policy
F - National Competitive Advantage: Porter's Diamond Model
Why a nation achieves international success in a particular industry?
Porter's thesis is that four broad attributes of a nation shape
the environment in which local firms compete, and these attributes
promote or impede the creation of competitive advantage.
a) Factor Endowments: skilled labour, infrastructure, technology,
etc. Advanced factors are the most significant for competitive
advantage.
b) Demand Conditions: home demand provides the impetus for upgrading
competitive advantage. A nation's firm gain competitive advantage
if their domestic consumers are sophisticated and demanding.
c) Related and Supporting Industries: Presence of suppliers or
related industries that are internationally supportive. Successful
industries within a country ten to be grouped into clusters of
related industries.
d) Firm Strategy, Structure, and Rivalry: Different nations are
characterized by different management ideologies; there is a strong
association between vigorous domestic rivalry and the creation
and persistence of competitive advantage in an industry.
e) Government: Business should urge government to increase its
investment in education, infrastructure, and basic research and
to adopt policies that promote strong competition within domestic
markets.
G - Country Similarity Theory: observations of actual trade patterns
reveal that most of world's trade occurs among countries that
have similar characteristics. Thus, overall trade patterns seem
to be at variance with the traditional theories that emphasize
country-by-country differences.
H - Pairs of Trading Relationships: How do you explain specific
pairs of trade relationships?
transport costs (natural traders)
Cultural Similarity
Historic Ties
Political Relationships and Economic Agreements
I - Independence, Interdependence, and Dependence
J - Trade Strategies Among Emerging Countries
- Outward-Led-Growth Strategies
- Import Substitution Industrialization
K - Why Companies Trade Internationally?
