Some Practical Questions
Is there such a thing called complete specialization?
1
Some Practical Questions
Is the North-South volume of trade flow larger than that of the North-North flow?
2
Some Practical Questions
Why do governments interfere in the free flow of goods if free international trade is welfare improving?
3
Some Practical Questions
What is the sources of comparative advantage (the source of differences in opportunity cost)?

The Hecksher-Ohlin (H-O) Theory of International
Trade
The Neo-Classical Explanation of Trade
History
Eli Heckscher (1919); 1949 ; Bertil Ohlin (1924; 1933)
The HO ……
Countries no longer differ in the level of technology, but in the amount of factors with which they are endowed (Factor Endowment)
1
The HO ..…
Compared to its trading partner, a country is either labor abundant or capital abundant.
Depends upon the relative capital labor ratios
i.e.,
The HO ..…
Goods differ in the amount of factors they require to be produced (i.e., in factor intensity)
Goods are either Capital or Labor intensive…
2
The HO Theory
A country should produce (and thus export) good (s), the production of which, requires an intensive use of the factor which is relatively abundant in that country
The HO Theory
countries will have a comparative advantage in the production of good (s) which uses the country’s relatively abundant factor more intensively
i.e.,
The HO Theory
International Trade is based on resource availability ( Factor Abundance); Not technological difference
Example…
Suppose we are concerned with trade between:
U.S.A. MEXICO
Autos
Textiles
Example…Data
USA: 50 Machines (K) & 100 Workers (L)Mexico: 25 Machines (K) & 75 Workers (L)
Assume that Autos are K intensive and Textile is Labor intensive….
Question….
In which country should each product be produced?
Solution….
The HO theory says: K intensive goods should be produced in K abundant countries; andL intensive goods should be produced in L abundant countries
Question….
Determine…Which country is K abundant?Which country is L abundant?
Solution….
U.S.A. 50/100 =1/2 = 0.50
Mexico 25/75 =1/3 = 0.33
Note that …Autos are K
IntensiveTextile is L Intensive
Capital Labor Ratios (K/L)
Solution….
Autos are K Intensive
Textile is L Intensive
Is Capital (K) abundant
Is Labor (L) abundant
Autos ….
Textile …
Some Real World Data
1. Is the U.S.A. capital or labor abundant country?
2. Which industries are K intensive?

Why should a country produce the good which uses its relatively abundant factor?
Why would the USA has to produce Autos and Mexico textiles?
The Rationale behind HO…Differences in relative factor price ratios…
If country A ( say, the USA ) is K abundant, it must be that the ratio of the returns to capital (i.e., rents) to that of labor (i.e., wages)…is lower in that country than the other.
…because capital (K) is abundant and hence cheaper, whereas Labor (L) is scarce and hence expensive.
The Rationale behind HO…Differences in relative factor price ratios…
• Similarly, if country B ( say, Mexico) is Labor abundant, it must be that the ratio of Rents to Wages (R/W) is higher in Mexico than the U.S.A.
… because capital is scarce and hence expensive and labor is abundant and hence cheaper.
Implications….
The basis of trade (comparative advantage) is autarky relative factor price differentials, which gives rise to differences in opportunity cost

The HO and Classical Theory: Differences
Under HO, there is no complete specialization… …factors are imperfect substitutes, and firms face increasing opportunity cost of completely transferring resources fro one sector to the other.
1
The HO and Classical Theory: Differences
Under HO, factor price equalization (resulting from adjustments in excess demand and supply), … not product price equalization
2
The HO and Classical Theory: Differences
Under HO, there are restriction on demand…tastes and preferences are assumed to be identical, … not under classical
