We examine the impacts of an unconditional cash transfer in Lesotho using an experimental impact evaluation design. We find that the cash transfer led to different outcomes for girls and boys, overall favouring secondary school-aged girls. Girls in this age group were less likely to miss school,...

This paper uses a duration analysis based on adoption data spanning over 25 years from six communities in the Central Highlands of Guatemala to explore how household characteristics and external trends play into both the adoption and diffusion processes of non-traditional exports among...

Undernourishment is still widespread in Tanzania, while obesity is becoming an issue of magnitude similar to undernutrition in the country. In this paper we examined the impact of an increase in maize prices on the nutritional status of Tanzania's adult population. We found that undernutrition...

Both men and women wish to have a family and a rewarding career. In this paper, we show that the under-representation of women in high-powered professions may reflect a coordination failure in young women?s marriage-timing decisions. Since investing in a highpowered career imposes time strain,...

The distribution of income within the household is found to matter for the allocation of resources towards nutrition. Rural Mexican households do not pool income, nor do they attain a Pareto-efficient allocation of resources. In contrast to what is commonly done in the literature, I do not...

We provide new results regarding the identification of peer effects. We consider an extended version of the linear-in-means model where each individual has his own specific reference group. Interactions are thus structured through a social network. We assume that correlated unobservables are...

We provide the first empirical application of a new approach proposed by Lee (2007) to estimate peer effects in a linear-in-means model. This approach allows to control for group-level unobservables and to solve the reflection problem. We investigate peer effects in student achievement in...

The common effect model in program evaluation assumes that all treated individuals have the same impact from a program. Our paper contributes to the recent literature that tests and goes beyond the common effect model by investigating impact heterogeneity using data from the experimental...

When one's treatment status affects the outcomes of others, experimental data are not sufficient to identify a treatment causal impact. In order to account for peer effects in program response, we use a social network model. We estimate and validate the model on experimental data collected for...
