Evidence from randomized evaluations is changing how we understand and address problems related to poverty. Policymakers, practitioners, and funders worldwide are increasingly applying this learning to social policies and programs.
Over 400 million people have been reached by programs that were scaled up after being evaluated by J-PAL affiliated researchers. Many more have benefitted from the several broader ways evidence can inform policy, outlined below.
Well-designed randomized evaluations test theories and provide general insights about how programs designed to address poverty work. These insights, when combined with descriptive data and a deep understanding of the local context and institutions, provide useful guides for policy design. Strong partnerships between implementers, researchers, and donors are critical to leveraging evidence to inform policy.
