本文研究了大麻合法化对社区犯罪的影响，并使用科罗拉多州丹佛市的详细微观数据记录了零售药房地点随着时间的推移的模式。为了解释内生零售药房地点，我们使用了一种新的识别策略，该策略利用了不同地点需求的外生变化，这些变化源于娱乐性大麻销售合法化后外部市场的重要性增加。结果表明，在一个社区增加一个药房，每10,000名居民每月减少17起犯罪，与样本期间的平均犯罪率相比，大约下降了19%。犯罪率的减少是高度本地化的，没有证据表明溢出效应会给邻近社区带来好处。对详细犯罪类别的分析有助于深入了解减少犯罪的机制。
This paper studies the effects of marijuana legalization on neighborhood crime and documents the patterns in retail dispensary locations over time using detailed micro-level data from Denver, Colorado. To account for endogenous retail dispensary locations, we use a novel identification strategy that exploits exogenous changes in demand across different locations arising from the increased importance of external markets after the legalization of recreational marijuana sales. The results imply that an additional dispensary in a neighborhood leads to a reduction of 17 crimes per month per 10,000 residents, which corresponds to roughly a 19 percent decline relative to the average crime rate over the sample period. Reductions in crime are highly localized, with no evidence of spillover benefits to adjacent neighborhoods. Analysis of detailed crime categories provides insights into the mechanisms underlying the reductions.
