Field experiments and the political economy of development

Social scientists have begun to work alongside developing country gov- ernments, nongovernmental organizations, and international organi- zations on experimental projects that address fundamental questions in the political economy of development. We describe the range of projects that have taken place or are currently under way, identify new and promising frontiers for research, and discuss some challenges that are particular to work in this area. The impact of this research will depend on the extent to which scholars can successfully link studies of experimental interventions to broader questions of social scientific interest.
