We conduct a controlled field experiment in 52 communities in rural Bolivia to investigate the effect that local authorities have on voluntary public good provision. In our study, community members pool resources to provide environmental education material for local schools. We find that...

Can pro-social preferences lead to dishonest or unethical behavior? Lab evidence suggests that it can. In this paper, we document some of the first field evidence of this phenomenon. In this study, individuals were hired as field staff and tasked with distributing subsidized price vouchers...

This paper examines the impact of health status on poverty status, accounting for the endogeneity of health status. Using exogenous measures of health status from the South African Integrated Health Survey, we instrument for health status while allowing for covariation among the unobservables...

This paper examines the relationship between employment risk and job-seeker performance. To induce exogenous variation in employment risk, the outside options for job seekers undergoing a real recruitment process were randomized by assigning them a 0, 1, 5, 50, 75, or 100 percent chance of real...

Objective: To examine whether individuals who learn that voluntary medical male circumcision (VMMC) partially reduces female-to-male HIV transmission erroneously infer a reduction in male-to-female HIV transmission risk. Design: Cluster randomised controlled trial. Methods: In 2008, information...
