中文摘要
枪支暴力是美国面临的一个重大问题，大量既有研究表明，气温升高会增加暴力行为。我们考察限制隐蔽携带枪支是缓解还是加剧了温度对暴力的影响。我们采用两种识别策略，利用温度的日度变化以及各州之间和州内枪支管制政策的差异进行识别。我们提供的证据表明，禁止性更强的隐蔽携带法律削弱了温度与凶杀之间的关系。我们的研究发现与如下结论一致：禁止性更强的政策体制降低了冲突的致命性。
Abstract
Abstract Gun violence is a major problem in the United States, and extensive prior work has shown that higher temperatures increase violent behavior. We consider whether restricting the concealed carry of firearms mitigates or exacerbates the effect of temperature on violence. We use two identification strategies that exploit daily variation in temperature and variation in gun control policies between and within states. We provide evidence that more-prohibitive concealed-carry laws attenuate the temperature-homicide relationship. Our findings are consistent with more-prohibitive policy regimes reducing the lethality of altercations.
