Neoclassical Growth and Commodity Trade

Cuñat, Alejandro; Maffezzoli, Marco - C.E.P.R. Discussion Papers - 2002

We construct and numerically solve a dynamic Heckscher-Ohlin model in which the initial distribution of production factors in the world makes worldwide factor price equalization impossible, and leads countries to group in two diversification cones. We study the dynamics of income per capita and...
