We outline six facts that should be explained by an international growth model: 1) Conditional convergence; 2) cross-country dispersion of growth rates; 3) cross-country dispersion of per capita income levels; 4) cross-country dispersion of savings rates; 5) within country correlation of savings...

We study a class of utility functions that are defined recursively by an aggregator function. In single-agent economies it is known that a sufficient condition for the existence of a balanced growth path is that utility should be homogenous. In the context of a multi-agent economy we show that...

In this Paper we study the competitive equilibria of a two-country endogenous growth model in which the source of growth is the linearity of technology in reproducible inputs. We begin by showing that in a model with no externalities there is a unique equilibrium; however, there are multiple...
