Factor accumulation and trade: Dynamic comparative advantage with endogenous physical and human capital

This article develops a two-country endogenous growth model with accumulation of both physical and human capital. We establish the existence of two-country balanced growth equilibria with physical and human capital in which a static and dynamic version of the Heckscher-Ohlin (HO) hypothesis hold true. We also show the existence of unbalanced growth equilibria in which the static and dynamic HO hypotheses can be violated. The multiplicity of paths with international trade emerge as a result of the intertemporal no-arbitrage condition when factor prices are equalized across countries.
