For a world in which international trade would be according to the differences featured in the Heckscher-Ohlin theory, the shift from no trade to free trade is like a zero-sum game." Do you agree or disagree? Why?

The Ricardian model emphasizes on theory of comparative advantage, viewed to be the most important concept in international trade theory. In a Ricardian model, countries specialize in producing what they produce best.

The Heckscher-Ohlin theory states that countries should produce and export goods that require resources (factors) that are abundant and import goods that require resources in short supply.

The latter theory was an alternative to the former model of comparative advantage. However, Heckscher-Ohlin did not provide accuracy in its forecasts. Despite that it did present a remarkable solution from the theoretical point of view by adopting neoclassical price mechanism into the International Trade Theory.

It may be borne in mind that 'demand plays a pivotal role so far the determination of equilibrium composition of output is concerned'.
