Based on some elementary results on duality, the paper proposes a much simpler way of deriving the class of non-homothetic CES production functions which was derived as a solution to a partial differential equation that defines the elasticity of substitution

We built an overlapping generation model of endogenous growth driven by human capital formation. Young people differ in their innate abilities, but these differences are not known even by the individuals themselves when they are going through the process of education, so that there are no...

This paper introduces a new duality concept, factor income function, in order to establish the factor Price Equalization theorem and the Heckscher-Ohlin theorem in an oligopolistic Heckscher-Ohlin model with increasing returns to scale

Constructing a simple dynamic North–South model in which factors of production are internationally immobile and there is no international credit market, it is possible that a persistent and unilateral foreign aid makes both North and South better off. We also show that the Pareto-improving...

Purpose – We ask how far the Kemp–Wan Pareto-improving result can hold without inter-country transfers. Methodology/approach – Assuming that the standard revenue and expenditure functions exist, we consider tariff adjustments for some group of countries such that they makes member...

Purpose – A free trade agreement (FTA) or a preferential trade agreement (PTA) is almost always negotiated without concessions to the non-member countries. This chapter studies the welfare effects of such an FTA or PTA on the non-member countries. Methodology/approach – This chapter employs...
