Contributions in the field of economics:
In 1933, Bertil Gotthard Ohlin modified and expanded an earlier economic theory of Heckscher on international trade in his book called “Interregional and International Trade”. It is this expanded theory of Ohlin on foreign trade which became popular in economics as the Hecksher-Ohlin model.
Specialty of the Hecksher-Ohlin model: The characteristic features of the Hecksher-Ohlin model is that it displayed the relationship existing between comparative advantage and the common features of the capital and labor of a particular nation, and the changes occurring in these features with passing time. In fact, the Hecksher-Ohlin model encouraged further researches on the consequences of protection on real wages. Moreover, Ohlin himself deduced the Heckscher-Ohlin theorem from this particular economic model.
The Heckscher-Ohlin Theorem: According to this theorem, inter-country trade is proportionate to the relative amounts of capital and labor of those countries. In countries where capital is abundant, there is an escalation in the wage rates. So, they go for capital-intensive productions and export the same, and import labor-intensive goods. It is on this exchange that the nature and trend of international trade is determined. The vice versa is true for a labour abundant country.
