We review the statistical models applied to test for heterogeneous treatment effects in the recent empirical literature, with a particular focus on data from randomized field experiments. We show that testing for heterogeneous treatment effects is highly common, and likely to result in a large...

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...

We investigate to what extent convergence in production levels per worker has been achieved in Germany since unification. To this end, we model the distribution of GDP per employee across German districts using two-component normal mixtures. While in the first year after unification, the two...

Using changes in the possession of household assets over the past 20 years, several recent papers have argued that economic performance in Arica was substantially better than suggested by national income data and income poverty statistics, who suffer from well-known weaknesses. We scrutinize...

Abstract: Despite recent improvements in economic performance, undernutrition rates in Africa appear to have improved much less and rather inconsistently across the continent. We examine to what extent there is an empirical linkage between income growth and reductions of child undernutrition in...

We examine the joint distribution of levels of income per capita, life expectancy, and years of schooling across countries in 1960 and in 2000. In 1960 countries were clustered in two groups; a rich, highly educated, high longevity “developed” group and a poor, less educated, high mortality,...

We investigate to what extent convergence in production levels per worker has been achieved in Germany since unification. To this end, we model the distribution of GDP per employee across German districts using two-component normal mixtures. While in the first year after unification, the...

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...
