International trade and
Factor-Mobility Theory
Chapter 6

The Importance of Trade Theory
Trade theory helps managers and
government policymakers focus on
three critical questions:
 What products should be imported and
exported?
 How much should be traded?
 With whom should they trade?

Economically

Interventionist theory
 Mercantilism is a trade theory holding that a
country’s wealth is measured by its holdings of
treasure which usually means its gold.
 According to mercantilism, countries should
export more than they import.
 Governments restricts imports, offer subsidies, use
colonies to supply commodities

Free Trade Theories:
Absolute & Comparative Advantage
• The theories of absolute and comparative
advantage demonstrate how economic growth can
occur via specialization and trade.
• Free trade (a positive-sum game) implies speciali-
zation and requires that nations neither artificially
limit imports nor artificially promote exports.
• The invisible hand of the market determines
which competitors survive, as customers buy
those products that best serve their needs.
Nations specialize in the production of certain products, some
of which may be exported; export earnings can in turn be used
to pay for imported goods and services.

Theory of Absolute Advantage
Absolute advantage [Adam Smith, 1776]:
A country can (i) maximize its own economic well being by
specializing in the production of those goods and services
that it produces more efficiently than any other nation and
(ii) enhance global efficiency through its participation in
free trade.
Smith reasoned that:
• workers become more skilled by repeating the
same tasks
• workers do not lose time in switching from the
production of one kind of product to another
• longer production runs provide greater incentives
for the development of more effective working methods

Natural vs. Acquired Advantages
 A natural advantage may exist because of:
-given climatic conditions
-access to particular resources
-the availability of labor, etc.
Example:
Wheat production in US
Coffee in Costa Rica
Tea in Sri Lanka

Acquired Advantages
 Countries that are competitive in manufactured
goods (but may lack agricultural goods and
natural resources) have an acquired advantage
 An acquired advantage may exist because of:
-superior skills
-better technology
-greater capital assets, etc.
Denmark exports silver tableware not because there
are rich Danish silver mines but because Danish
companies have developed distinctive products
Real income depends on the output of products as compared to the
resources used to produce them.

Production Possibilities with Absolute Advantage

Theory of Comparative
Advantage
Comparative advantage [David Ricardo, 1817]:
A country can (i) maximize its own economic well-being by
specializing in the production of those goods and services
it can produce relatively efficiently and (ii) enhance global
efficiency via its participation in free trade.
Ricardo also reasoned that:
• a country can simultaneously have an absolute
and a comparative advantage in the production of a given
product
• by concentrating on the production of the product in
which it has the greater advantage, a country can further
enhance both global output and its own economic well-being

Production Possibilities with Comparative Advantage

 US is more efficient than Costa Rica in producing both wheat
and coffee and has an absolute advantage in the production of
both.
 But US has comparative advantage only in production of wheat
(wheat – 2.5 times that of CR; coffee – 2 times of CR)
 Costa Rica has an absolute disadvantage in the production of
both
 Has a comparative advantage (or less of a comparative
disadvantage) in the production of coffee (coffee - CR is 50%
as efficient as US; wheat – 40% as efficient as US)

Assumptions and Limitations
of the Free Trade Theories
The theories of absolute and comparative advantage
both make assumptions that may not be entirely valid.
 Full employment of resources
 Exclusive pursuit of economic efficiency objectives
 Equitable division of gains from specialization
 Only two countries and two commodities
 Exclusion of transport costs
 A static rather than a dynamic view
 Exclusion of services
 Factor mobility

Theories Explaining Patterns of
Trade: Country Size, Factor
Proportions, Country Similarity
The theories of country size, factor proportions,
and country similarity all contribute to the
explanations of:
 what types of products are traded
 with which partner nations countries will
primarily trade
Nontradable products are those goods and services
that are impractical to export.

Theory of Country Size
Large countries differ from small countries in at least two
critical ways:
• Large countries tend to export a smaller portion of their output
and import a small portion of their consumption.
Large countries are more apt to have varied climates and a greater assortment
of natural resources than smaller countries, thus making large countries more self-
sufficient.
• Large countries tend to have higher transportation costs for
exported and imported products.
Given the same types of terrain and modes of transportation, the greater the
distance, the higher the associated transport costs. Thus, firms in large countries
often face higher transport costs in terms of sourcing inputs from and delivering
outputs to distant foreign markets than do their closer foreign competitors.

Factor Proportions Theory
• Differences in a country’s relative endowments of
land, labor, and capital explain differences in the cost
of production factors.
• A country will tend to export products that utilize
relatively abundant production factors because they
are relatively cheaper than scarce factors.
The composition of a country’s trade depends on both its natural and acquired
advantages. With respect to the latter, both production and product
technology can be very important.

Country Similarity Theory
When a firm develops a new product in response to
observed conditions in its home market, it is likely to
turn to those foreign markets that are most similar to its
domestic market when commencing its initial
international expansion activities. This tendency is
reflective of:
• the cultural similarity of nations
• the similarity of national political/economic interests
• the economic similarity of industrialized countries
Countries that are near to one another enjoy relatively lower transportation
costs than those that are more distant, but they may or may not be similar with
respect to culture, level of economic development, and/or political/economic
interests.

Factor Mobility
Factor mobility concerns the free movement of factors of
production, such as labor and capital, across national borders.
 While capital is the most internationally mobile factor, short-
term capital is the most mobile of all.
Capital is primarily transferred because of differences in expected
returns, but firms may also respond to government incentives.
• People transfer internationally in order to work abroad, either
on a temporary or on a permanent basis. Motives are:
 economic motives
 political motives
Brain drain occurs when educated citizens leave a country, but a nation may in
turn gain from the remittances that citizens who are working abroad send home.

International Trade and Factor
Mobility—Relationship
 Substitution: the inability to gain sufficient access to
foreign production factors may stimulate efficient
methods of domestic substitution, such as the develop-
ment of alternatives for traditional production methods
 Complementarity: factor mobility via foreign direct
investment may stimulate foreign trade because of
the need for equipment, components, and/or
complementary products in the destination country
While immigrants add to the base of a country’s skills, thus enabling
competition in new areas, inflows of capital can be used to develop
infrastructure and natural and other acquired advantages, thus
enabling increased participation in the international trade arena.

Unrestricted trade and factor mobility
 US and Mexico have equally productive land available
at the same cost for growing tomatoes.
 The cost of transporting tomatoes between the two
countries is $0.75 per bushel
 Workers from either country pick an average of two
bushels per hour during a 30-day picking season.
 Labour cost is $20 per day ($1.25 per bushel) in the
US and $4 per day ($0.25) in Mexico
 Capital needed to buy seeds, fertilizers and equipment
costs are $0.30 per bushel in US and $0.50 in Mexico

Example:
US
Without free trade
 Labor rate - $1.25/bushel
 Capital - $0.30/bushel
 Total cost - $1.55/bushel
With free trade with
transportation costs of
$0.75
Import from Mexico gives
total cost of $1.50 which is
0.05 cheaper
Mexico
 $0.25 / bushel
 $0.5/bushel
 $0.75/bushel

Trade restriction – mobility of
resources
 A scenario in which neither country allows the import
of tomatoes but both allow certain movements of
labor and capital
 Mexican workers can enter the country the US on
temporary work permits for an incremental travel and
living expense of $14.40 per day per worker (0.90 per
bushel) .
 At the same time, US companies will invest capital in
Mexican tomato production, provided the capital earns
more than it would earn in the US i.e. $0.40 per
bushel which is less than the Mexican going rate.

Labor and capital mobility
 Mexican labor work permit cost = $.90/bushel
 US capital is invested in Mexico at 0.40/bushel
 Mexican production costs = $0.65 ($0.25 of
Mexican labor plus $0.40 of US capital)
 US production costs = $1.45 (0.25 labor wage
+0.9 work permit +0.30 capital cost)
 Each country would reduce its production costs –
from $0.75 to $0.65 in Mexico and from $1.55 to
$1.45 in the US by bringing in abundant
production factors from abroad.

Summary of conclusions from
two examples
US
 No trade or factor mobility $1.55
 Trade mobility but no factor mobility $1.50
 Factor mobility but no trade mobility $1.45
 Both trade and factor mobility $1.40
Mexico
 $0.75
 $0.75
 $0.65
 $0.65

Implications/Conclusions
 Production factors are neither as mobile nor as immobile
as theories assume.
 The free trade theories of absolute and comparative
advantage are descriptive in nature.
 The theories of country size, factor proportions, and
country similarity help explain patterns of trade.
 Although the international mobility of production factors
may be a substitute for trade, that same mobility may
stimulate trade because of the need for equipment,
components, and/or complementary products in the
destination country.
