The Impact of Terrorism on Social Capital: Evidence from the 2015 Charlie Hebdo Paris Shooting
利用2014年欧洲社会调查的访问时间差异和2015年巴黎《查理周刊》袭击事件，研究发现恐怖袭击短期内显著提升了法国受访者的社会资本，尤其是制度信任、人际信任和社交网络参与，但约一个月后恢复至袭击前水平。
Abstract We examine the impact of terrorism on social capital by exploiting variation in the 2014 European Social Survey administration dates coupled with the 2015 Charlie Hebdo attack in Paris, France. Using the difference‐in‐differences estimator, we find that the attack had a positive, causal impact on the overall level of social capital among French respondents. Further, the effect seems to be driven by an increase in institutional and interpersonal trust, as well as by engagement in social networks. This rise in social capital peaks in the immediate aftermath of the terrorist attack but subsequently decays to pre‐attack levels within approximately one month.
