Specialization and Welfare in the Presence of Imperfectly Integrated Capital Markets and Learning-by-Doing

We study a two-sector, two-period model with learning externalities in the modern sector and imperfectly integrated capital markets. We find that higher capital market integration lowers the requirements on the learning pattern necessary for free trade to lead to an equilibrium with maximal specialization in modern sector activities. We further find that the equilibrium with maximal specialization in modern sector activities Pareto dominates, if it exists, any other free trade equilibrium, and that autarky can Pareto dominate free trade if capital markets are poorly integrated, even when there is maximal specialization in modern sector activities under free trade
