摘要翻译:
这项工作调查了新冠肺炎遏制政策是否以及如何对洛杉矶的犯罪趋势产生了直接影响。该分析使用贝叶斯结构时间序列进行,重点是从2017年1月1日至2020年3月28日每天监测的九个犯罪类别和总体犯罪数量。我们集中在两个干预后时间窗口--2020年3月4日至3月16日、3月4日至3月28日--动态评估温和和严厉政策的短期效果。在洛杉矶,总体犯罪率显著下降,抢劫、入店行窃、盗窃和殴打也是如此。对车辆盗窃、入室盗窃、使用致命武器袭击、亲密伴侣袭击和杀人没有发现重大影响。结果表明,在干预措施到位后的头几周,社交距离对工具性和不太严重的犯罪影响更直接。还讨论了政策含义。

英文摘要:
This work investigates whether and how COVID-19 containment policies had an immediate impact on crime trends in Los Angeles. The analysis is conducted using Bayesian structural time-series and focuses on nine crime categories and on the overall crime count, daily monitored from January 1st 2017 to March 28th 2020. We concentrate on two post-intervention time windows - from March 4th to March 16th and from March 4th to March 28th 2020 - to dynamically assess the short-term effects of mild and strict policies. In Los Angeles, overall crime has significantly decreased, as well as robbery, shoplifting, theft, and battery. No significant effect has been detected for vehicle theft, burglary, assault with a deadly weapon, intimate partner assault, and homicide. Results suggest that, in the first weeks after the interventions are put in place, social distancing impacts more directly on instrumental and less serious crimes. Policy implications are also discussed.
