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...

"The authors use a sample of 147 countries to investigate the link between democracy and reforms. Democracy may be conducive to reforms, because politicians have the incentive to embrace growth-enhancing reforms to win elections. By contrast, authoritarian regimes do not have to worry as much...

This paper proposes a theory for the gradual evolution of knowledge diffusion and growth over the very long run. A feedback mechanism between capital accumulation and the ease of knowledge diffusion explains a long epoch of (quasi-) stasis and an epoch of high growth linked by a gradual economic...

We examine the long-run relationship between fertility, mortality, and income using panel cointegration techniques and the available data for the last century. Our main result is that mortality changes and growth of income per capita account for a major part of the fertility change...

This paper proposes a theory for the evolution of knowledge diffusion and growth over the very long run. A feedback mechanism between capital accumulation and knowledge spillovers creates a unified growth theory that explains a long epoch of (quasi-) stasis and an epoch of high growth linked by...
