Have U.S. gun buyback programs misfired?
研究利用美国全国性数据，发现枪支回购计划对减少枪支犯罪、自杀或他杀没有显著效果，质疑其当前形式的有效性。
Abstract Gun buyback programs (GBPs), which use public funds to purchase civilians' privately‐owned firearms, aim to reduce gun violence. However, next to nothing is known about their effects on firearm‐related crime or deaths. Using data from the National Incident Based Reporting System, we find no evidence that GBPs reduce gun crime. Given our estimated null findings, with 95% confidence, we can rule out decreases in firearm‐related crime of greater than 1.2% during the year following a buyback. Using data from the National Vital Statistics System, we also find no evidence that GBPs reduce suicides or homicides where a firearm was involved. These results call into question the efficacy of city gun buyback programs in their current form.
