Impact evaluations

These are final reports of 3ie-supported impact evaluations that assess the difference a development intervention has made to social and economic outcomes. We fund rigorous evaluations that include a theory-based experimental or quasi-experimental design, and we use the most appropriate mix of methods to capture outcomes and answer what works, for whom, why and at what cost.
