Evidence from economics, anthropology and biology testifies to a fundamental household trade-off between the number of offspring (quantity) and amount of nutrition per child (quality). This leads to a theory of pre-industrial growth where body size as well as population size is endogenous. But...

In this paper we analyze the distribution of fertility rates across the world using parametric mixture models. We demonstrate the existence of twin peaks and the division of the world's countries in two distinct components: a high-fertility regime and a low fertility regime. Whereas the...
