Short Questions
1. ʹThe H.O. model remains useful as a way to predict the income distribution effects of trade.ʹ Discuss.
Answer:
T he Stolper-Samuelson theorem, one of the basic theorems arising from the
Heckscher-Ohlin model yields an elegant demonstration of the fact that changes in product prices （such as will occur when trade is expanded or curtailed） telescopes its effects onto factor prices, so that not only do relative factor returns mirror product prices, but that actual returns to factors may either rise or fall in real terms. Hence, as a policy framework, the disproportionate effect trade may have on real incomes of sectors, such as skilled-labor is quite useful both theoretically and practically （or polemically）
2. International trade leads to complete equalization of factor prices. Discuss.
Thisstatement is typically ʹtrue . . . but.ʹ Under a strict and limited set of assumptions, such as the original Heckscher-Ohlin model which excludes country specific technologies; non- homothetic tastes; factor intensity reversals; large country differences in （relative） factor abundances, more factors than goods, and an equilibrium solution within the ʹcone of specializationʹ; then it may be
demonstrated that internal consistency demands that the above stated sentence is ʹtrue.ʹ However, the minute one relaxes any of the above listed assumptions one may easily identify solutions, which contradict the factor price equalization theorem.
3. If a scale economy is the dominant technological factor defining or establishing comparative
advantage, then the underlying facts explaining why a particular country dominates world markets in some product may be pure chance, or historical accident. Explain, and compare this with the answer you would give for the Heckscher-Ohlin model of comparative advantage.
T his statement is true, since the reason the seller is a monopolist may be that it happened to have been the first to produce this product in this country. It may have no connection to any supply or demand related factors; nor to any natural or man-made availability. This is all exactly the opposite of the Heckscher-Ohlin Neo-Classical modelʹs explanation of the determinants of comparative advantage.
