In this paper, we study the evolution of the distribution of fertility rates across the world from 1950 to 2005 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...

In a recent paper in the Review of Economic Studies, Siwan Anderson and Debraj Ray (Anderson and Ray, 2010) develop and apply a new ‘flow’ measure of ‘missing women’ to estimate the extent of gender bias in mortality in developing countries. Contrary to the existing literature, they find...

Almost nine million children under five years of age die every year. Diarrhea is considered to be the second leading cause of under-five mortality in developing countries. About one out of five deaths is caused by diarrhea. In this paper, we use the newly available data set DLHS-3 to quantify...

Over the last 200 years humans experienced a huge increase of life expectancy. These advances were largely driven by extrinsic improvements of their environment (for example, the available diet, disease prevalence, vaccination, and the state of hygiene and sanitation). In this paper we ask...
