Knowledge dissemination, capital accumulation, trade, and endogenous growth

This paper preserves many of the primary features of the standard neoclassical framework while introducing some modifications that transform it into an open economy endogenous growth model with knowledge accumulation. The accumulation of knowledge is determined in part by the extent of knowledge spillovers from abroad, which in turn are affected by commercial policy that regulates the extent of trade between countries. The model predicts that trade liberalization (even if it is unilateral) will increase steady-state output growth in all countries while benefitting the liberalizing country the most in terms of relative income levels.
