论文摘要
在纽约市，邻里警务在2015 - 2018年间在警察区域采用，两者都很感兴趣（1）评估该政策的影响，以及（2）了解哪些类型的社区受到政策的影响，提出了异构治疗效果的问题。我们开发了新颖的统计方法，这些方法可以强大，以实现无法衡量的混杂偏见，以研究社区一级实施的政策的因果效应。我们发现，邻里警务减少了城市某些地区的酌处逮捕，但对逮捕率的犯罪或种族差异影响不大。
In New York City, neighborhood policing was adopted at the police precinct level over the years 2015-2018, and it is of interest to both (1) evaluate the impact of the policy, and (2) understand what types of communities are most impacted by the policy, raising questions of heterogeneous treatment effects. We develop novel statistical approaches that are robust to unmeasured confounding bias to study the causal effect of policies implemented at the community level. We find that neighborhood policing decreases discretionary arrests in certain areas of the city, but has little effect on crime or racial disparities in arrest rates.
