We study the causal impact of network centrality on educational outcomes using field experiments in primary schools in Bangladesh. After obtaining information on friendship networks, we randomly allocate students into groups and give them individual and group assignments. We find that groups...

Starting from the recent UNICEF publications on child poverty in the developed countries, which received a wide audience in the political and scientific world, in this paper we further analyze the UNICEF study data base and present three composite indices that are multidimensional and...

The paper argues that access to public infrastructure plays a crucial role on the presence of private schools in a community, as it could not only minimise the cost of production, but also ensure a high return to private investment. Results using community, school and child/household-level PROBE...

We identify the ages that constitute critical periods in children's development towards their adult health status. For this we use data on families migrating into Sweden from countries that are mostly poorer, with less healthy conditions. Long-run health is proxied by adult height. The relation...

This article analyzes whether the commonly found negative relationship between parental separation in childhood and educational outcomes is causal or mainly due to selection. We use data on about 100,000 Swedish full biological siblings, born in 1951-64, and perform cross-section and...

I ask generally whether a country can benefit from the temporary importation of human capital, and specifically whether a program that attracts large groups of academic visitors to a distant country benefits it by generating additional scholarly research on local issues. Using the list of...

This study examines the relationship between the diffusion of IT and changes in collaboration patterns across institutional and national borders. To undertake the research, the authors match an explicit measure of institutional IT adoption (domain names, e.g. www.umsl.edu) with institutional...

This story describes the circumstances that led to all five of us starting as editors at the same time, the unexpected things we have found, the unanticipated reactions we have encountered, how we worked as an editorial team, the central role of the editorial office manager, how we managed to...

We study peer effects in crime by analyzing co-offending networks. We first provide a credible estimate of peer effects in these networks equal to 0.17. This estimate implies a social multiplier of 1.2 for those individuals linked to only one co-offender and a social multiplier of 2 for those...

This paper studies whether structural properties of friendship networks affect individual outcomes in education. We first develop a model that shows that, at the Nash equilibrium, the outcome of each individual embedded in a network is proportional to her Katz-Bonacich centrality measure. This...
