This paper looks at horizontal sex segregation in education as a factor contributing to gender segregation in the labor market. Economic theories fail to explain why women with the same years of schooling and educational attainment as men are under-represented in many technical degrees, which...

Self-esteem has been conceptualized as a "social vaccine". The belief is that high self-esteem can inoculate young people, against vulnerability to a wide range of social illnesses. This study gives a contribution in the understanding of the causal relation between self-esteem and sexual...

In previous literature, social capital has been hypothesized as a substitute for other forms of capital, such as physical and human capital. This paper contributes to this literature, studying the association between mothers'access to social capital via participation in community organizations...

This paper examines the causal link between early childhood nutrition and cognition, applying instrumental variables to sibling-differences for a sample of preschool aged Peruvian children. Child-specific shocks in the form of food price changes and household shocks during the critical...

In 1984, the world was shocked at the scale of a famine in Ethiopia that caused over half a million deaths, making it one of the worst in recent history.  The mortality impacts are clearly significant.  But what of the survivors?  This paper provides the first estimates the long-term impact...

This paper makes three contributions to the literature on intertemporal poverty measurement, in particular the aggregation of a measure of wellbeing over time and across people.  Firstly we conduct an exhaustive analysis of properties of intertemporal poverty measures, identifying relationships...

This paper examines the causal link between early childhood nutrition and cognition, applying instrumental variables to sibling-differences for a sample of pre-school aged Peruvian children. Child-specific shocks in the form of food price changes and household shocks during the critical...

An extensive literature documents linkages between early nutritional deficiencies and reduced cognitive ability, educational attainment and, ultimately, lower labor market performance. Few of these studies, however, have shown these correlations to be genuinely causal. We reexamine the nutrition...
