Abstract

This short paper presents a simple analytical stability proof for the well-known Segerstrom (1998) model of endogenous growth. Moreover, a calibrated version of the model is employed to assess the speed of convergence. The result shows that transitional dynamics are important and, hence, the policy ineffectiveness proposition of non-scale endogenous growth models must be qualified.
