What makes a good manager good? We let the data tell us -- and find that hard-to-observe things like attention and control have large effects on productivity, and are drastically undervalued in manager pay.

Dust from the annual harmattan winds increases infant and child mortality in West Africa, but human adaptation has tapered these impacts over a 20 year period.

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.

Individuals who enjoyed greater access to elite bureaucratic jobs invested more in schooling and achieved better labor market outcomes.

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.

Enabling worker voice through a two-way, anonymous, SMS-based technology decreases absenteeism and turnover, despite infrequent usage. Our findings suggest a substantial option value of voice, which can promote positive workplace behaviors even when workers do not directly avail themselves of the technology.

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.

Can policy protect against the often devastating human impacts of environmental shocks? 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.
