Question

What does the Heckscher–Ohlin theory postulate? Which force do Heckscher and Ohlin identify as the basic determinant of comparative advantage and trade? 

Answer 1

Heckscher-Ohlin theory, in economics, a theory of comparative advantage in international trade according to which countries in which capital is relatively plentiful and labour relatively scarce will tend to export capital-intensive products and import labour-intensive products, while countries in which labour is relatively plentiful and capital relatively scarce will tend to export labour-intensive products and import capital-intensive products.

Heckscher-Ohlin asserts that differences in comparative advantage come from differences in factor abundance and in the factor intensity of goods.
