We show that prominent centrality measures in network analysis are all based on additively separable and linear treatments of statistics that capture a node's position in the network. This enables us to provide a taxonomy of centrality measures that distills them to varying on two dimensions:...

We study the consequences of job markets' heavy reliance on referrals. Referrals screen candidates and lead to better matches and increased productivity, but disadvantage job-seekers who have few or no connections to employed workers, leading to increased inequality. Coupled with homophily,...

The 'friendship paradox' (Feld1991) refers to the fact that, on average, people have strictly fewer friends than their friends have. I show that this over-sampling of the most popular people amplifies behaviors that involve complementarities. People with more friends experience greater...

Sharing is a norm in many societies. We present a theoretical model on the trade-off between sharing and investment which we test on data from tailors in Burkina Faso. The empirical results support the idea that there are two behavioural patterns: entrepreneurs following an 'insurance regime'...

We conducted a field experiment in Burkina Faso to investigate the impact of sharing obligations within kin networks on entrepreneurial effort. The overall treatment effect we find is insignificant and goes in the opposite direction than previous literature suggests. Ex-post explorative analysis...

I analyze a model of human capital development in the presence of peer effects. Parents invest in their child, and this investment conveys a positive externality upon the child’s peers. Parents also acquire wealth, which i) finances consumption, and ii) determines a child’s peer group. I...

Labor force participation is crucial to the economic well-being of low-income rural families. This study identified the factors that influence two decisions that low-income rural mothers make regarding their employment: labor force entry and number of hours supplied to employment. The sample...

Programs that increase the economic capacity of poor women can have cascading effects on children's participation in school and work that are theoretically undetermined. We present a simple model to describe the possible channels through which these programs may affect children's activities....

Incorporating family decisions in a two-period.model of the world economy, we predict that trade liberalization raises the skill premium and reduces child labour in developing countries where the adult labour force is sufficiently well educated to attract production activities from abroad that...

I examine the role of family structure and child care subsidies in child skill accumulation. I establishempirically that skill accumulation is more responsive to child care price for one-parentfamilies than for two-parent families. I analyze the effects of child care subsidies in a...
