No understanding of the economic development of modern Africa can be complete without an appreciation of the role of natural resources. Our study is at the nexus of resources, conflict, and development, using theory and high-resolution spatial data from sub-Saharan Africa. Our results help explain why the most resource-rich countries are no better off than the most resource-poor.

Do talented managers match with productive workers, or with those who are struggling to perform? We find negative assortative matching of managers and workers. Despite supermodularity of production, "misallocating" managerial skill in this way may be optimal for firms who value buyer relationships.

Relational contracts are essential building blocks of the theory of the firm, but we know little about the form or function of these contracts in practice. We study the behavior of managers who share workers across teams to weather absenteeism shocks. Relationships have some smoothing value, but many potentially beneficial transfers are left unrealized. We simulate the gains to increased relationship formation and find that the firm could reduce worker misallocation and increase productivity substantially by spurring relationship formation.

We study this question by leveraging data from a situation in which a tornado tore through an area involved in a double-blind cluster-randomized controlled trial of at-birth vitamin A supplementation in Bangladesh.

We ask whether information can be delivered without negative consequences to mental health. We randomly assigned individuals to receive Covid-19 information through text messages, a pre-recorded audio message, or phone calls. Phone calls were effective at engaging individuals. They improved Covid-19 knowledge and reduced depression and anxiety; the amount of information delivered does not account for this effect.
