Growth and Interdependence under Complete Specialization

We construct and numerically solve a dynamic Heckscher-Ohlin model in which the initial distribution of production factors in the world makes world-wide factor price equalization impossible, and leads countries to group in two diversification cones. We study the dynamics of income components and factor prices. Our results suggest that the Ramsey model under complete specialization (CS) overcomes several shortcomings of its autarchy and factor-price-equalization (FPE) counterparts. In comparison with the autarchy model, it can account for important cross-sectional differences in income per capita growth rates without generating too large rental-rate differentials across countries. Furthermore, the CS model generates cross-country convergence in growth rates and levels along the transition towards the steady-state. Finally, the CS model converges to FPE in the long run. Unlike the autarchy model, FPE does not necessarily yield convergence in levels; however, international trade is beneficial to both countries in terms of welfare.

Long-Run Equilibria in a Dynamic Heckscher-Ohlin Model

The goal of this paper is to study long-run equilibria in open economies using a new dynamic Heckscher-Ohlin model with endogenous savings and endogenous labor supply. The long-run equilibria in this model exhibit the property of economic hysteresis. The model offers a Heckscher-Ohlin type explanation for the long-run trade between countries with identical preferences; that is, a difference in factor endowment ratios in the initial period causes trade to continue in the long run. It is shown that factors other than differences in preferences can lead to a difference in savings rates among countries.
