Monopoly, intermediate goods and the pure theory of international trade

Abstract

In a model with two traded good sectors between which intersectoral flows of intermediate goods are allowed and with a monopolized non-traded good sector, the wage rate in terms of two traded goods increases and the rental of capital in terms of two traded goods decreases when the price of relatively more labor intensive traded good sector increases, though nothing definite can be said about the direction of change in the wage rate and rental in terms of the non-traded good. When prices of traded goods are kept constant and labor and/or capital increase(s), output of the non-traded good sector increases provided that the non-traded good is not inferior, having income elasticity of demand less than unity. The factor intensity condition for the traded goods is in general not sufficient for the validity of the Rybczynski theorem to hold with respect to net outputs of the traded goods. We have derived sufficient conditions for the magnification effect to be observed with respect to net outputs of the traded good sectors. Specifically, we have shown that the factor intensity condition (23) is sufficient for the magnification effect to prevail when only labor increases.
