This study provides a unified growth theory to correctly predict the initially negative and subsequently positive relationship between child mortality and net reproduction observed in industrialized countries over the course of their demographic transitions. The model captures the intricate...

Conventional R&D-based growth theory suggests that productivity growth is positively correlated with population size or population growth, an implication which is hard to see in the data. Here we integrate microfounded fertility and schooling into an otherwise standard R&D-based growth model. We...

The demographic transition can affect the equilibrium real interest rate through three channels. An increase in longevity - or expectations thereof - puts downward pressure on the real interest rate, as agents build up their savings in anticipation of a longer retirement period. A reduction in...
