A Generalized Multi-Country Endogenous Growth Model

Abstract

The transitional dynamics of open-economy endogenous growth models are largely unexplored. The present paper fills this gap in the literature. By applying the familiar Travis–Dixit–Norman (Dixit and Norman, Theory of International Trade, Cambridge University Press, Cambridge, UK, 1980) approach to a general class of growth models, it provides original results on the transitional dynamics of the multi-country open-economy versions of several prominent special cases, including the models of Romer (J Polit Econ, 94:1002–1037, 1986; J Polit Econ 98:S71–S102, 1990), Lucas (J Monet Econ, 22:3–42, 1988), Grossman and Helpman (Innovation and Growth in the Global Economy. MIT Press, Cambridge, MA, 1991a, Chaps. 3 and 4; Rev Econ Stud 58:43–61, 1991b), Jones (J Polit Econ, 103:759–784, 1995a), and Segerstrom (Am Econ Rev, 88:1290–1310, 1998). This approach also shows that, in the class of models considered, the question of whether or not international economic integration accelerates growth in the long run is equivalent to the question of whether or not scale effects prevail.
