We analyze the largest set of nations (n = 55) with a valid measure of gun ownership levels ever used to test the effect of national gun levels on homicide rates. We control for measures of national culture to better isolate the effects of firearm availability. We find that, while national gun levels have a significant positive bivariate correlation with homicide rates, once one controls for violence-related cultural differences between nations, the association disappears. With this larger, more diverse set of nations, the U.S. is not influential – gun levels are unrelated to homicide rates regardless of whether it is included in the analysis.

枪支水平对凶杀率的影响：跨国研究中文化差异的控制效应

我们 使用有效的枪支拥有量衡量标准，分析了最大的一组国家（n = 55），该量度曾经用来测试国家枪支占有率对凶杀率的影响。我们控制民族文化的措施，以更好地隔离枪支供应的影响。我们发现，尽管国家层面的枪有显著正二元与杀人率的相关性，曾经为国家之间的暴力有关的文化差异一个控件，该协会消失。在这个更大，更多样化的国家中，美国没有影响力-枪支水平与凶杀率无关，无论其是否包括在分析中。
