This paper describes a model and resulting simulations to assess the appropriate age structure of intervention in childhood on the theme: should we intervene early or late? We use asset theory approaches to construct a general model of state investment whose aim is to reduce inequality in human...

We use the control function approach to identify the average treatment effect and the effect of treatment on the treated in models with a continuous endogenous regressor whose impact is heterogeneous. We assume a stochastic polynomial restriction on the form of the heterogeneity but, unlike...

The Trivers Willard hypothesis – that higher maternal quality is associated with a higher sex ratio – is tested using a large population survey from 12 European countries. Several outcomes are studied, the proportion of children born who are male and the sex of the first three children. The...
