Crime and the Depenalization of Cannabis Possession: Evidence from a Policing Experiment
研究伦敦兰贝斯区一项将少量大麻持有非刑事化的警务实验对犯罪的影响，发现警察将精力转向非毒品犯罪，犯罪总体下降但居民福利可能下降，并构建结构模型预测全市范围政策的影响。
We evaluate the impact on crime of a localized policing experiment that depenalized the possession of small quantities of cannabis in the London borough of Lambeth. We find that depenalization policy caused the police to reallocate effort towards non-drug crime. Despite the overall fall in crime attributable to the policy, we find the total welfare of local residents likely fell, as measured by house prices. We shed light on what would be the impacts on crime of a citywide depenalization policy, by developing and calibrating a structural model of the market for cannabis and crime.
