The factor-endowments-driven model (FED model) has errors much greater than the HOV model. [12] Unemployment is the vital question in any trade conflict. Heckscher–Ohlin theory excludes unemployment by the very formulation of the model, in which all factors (including labour) are employed in the production. [13]
The Heckscher–Ohlin theorem is one of the four critical theorems of the Heckscher–Ohlin model, developed by Swedish economist Eli Heckscher and Bertil Ohlin (his student). In the two-factor case, it states: "A capital-abundant country will export the capital-intensive good, while the labor-abundant country will export the labor-intensive good."
In the early 1900s, a theory of international trade was developed by two Swedish economists, Eli Heckscher and Bertil Ohlin. This theory has subsequently become known as the Heckscher–Ohlin model (H–O model). The results of the H–O model are that the pattern of international trade is determined by differences in factor endowments.
Traditional trade models relied on productivity differences (Ricardian model of comparative advantage) or factor endowment differences (Heckscher–Ohlin model) to explain international trade. New trade theorists relaxed the assumption of constant returns to scale, and showed that increasing returns can drive trade flows between similar ...
This econometric finding was the result of Wassily W. Leontief's attempt to test the Heckscher–Ohlin theory ("H–O theory") empirically. In 1953, Leontief found that the United States—the most capital-abundant country in the world—exported commodities that were more labor-intensive than capital-intensive, contrary to H–O theory. [1]
The Rybczynski theorem displays how changes in an endowment affects the outputs of the goods when full employment is sustained. The theorem is useful in analyzing the effects of capital investment, immigration and emigration within the context of a Heckscher-Ohlin model. Consider the diagram below, depicting a labour constraint in red and a ...
An additional robust corollary of the theorem is that a compensation to the scarce factor exists which will overcome this effect and make increased trade Pareto optimal. [3] The original Heckscher–Ohlin model was a two-factor model with a labor market specified by a single number. Therefore, the early versions of the theorem could make no ...
Since 1817, economists have attempted to generalize the Ricardian model and derive the principle of comparative advantage in broader settings, most notably in the neoclassical specific factors Ricardo-Viner (which allows for the model to include more factors than just labour) [19] and factor proportions Heckscher–Ohlin models.
