Crime, Violence, and Conflict
Crime and violence can hinder economic development and urban growth, and exacerbate governance challenges by fostering corruption and draining public sector resources. Poorly designed efforts to prevent or reduce crime and violence can also impose substantial social and economic costs on communities.
Key questions include the motivations behind criminal and violent behavior, ways of better understanding how social and political violence are organized, and evaluating the impact of policy responses designed to deter crime and violence or alleviate their negative effects. J-PAL affiliates’ research explores critical questions in this field, including how to cost-effectively improve police performance and perception, help at-risk youth reduce criminal and violent behavior, and reconcile communities in post-conflict fragile states.
In addition to supporting policymakers in applying evidence from randomized evaluations to their work, sector chairs and staff write policy insights that synthesize general lessons emerging from the research, condense results from evaluations in policy publications and evaluation summaries, and fund new research in low- and middle-income countries through the Crime and Violence Initiative and in the United States through the Initiative for Effective US Crime Policy.
