  Cure Violence is a community violence intervention program that aims to
reduce gun violence by mediating conflicts, "treating" high-risk individuals,
and changing community norms. Using NYC shootings data from 2006-2023, we
assess the efficacy of Cure Violence using both difference-in-differences and
event study models. We find that, on average, Cure Violence is associated with
a 14% reduction in shootings relative to the counterfactual. This association
persists in the years after treatment, neither increasing nor decreasing much
over time. We exploit variation in the geography and timing of Cure
implementation to argue against alternative explanations. Additionally, we find
suggestive evidence of spillover effects into nearby precincts, as well as
increasing returns to opening new Cure programs. Interpreted causally, our
results imply that around 1,300 shootings were avoided between 2012-2023 due to
Cure -- generating a net social surplus of $2.45 billion and achieving a
benefit-cost ratio of 6.5:1.
