In this paper, we evaluate the effect of international terrorism on the civil liberties of the targeted states from 1972 through 2018, using a cross-country dataset. To deal with the problem of selection and control for the pre-attack dynamics, we use a potential outcomes framework to uncover the effect of the treatment on the outcome variable over time. In democracies, civil liberties are restricted after an international terrorist attack. The identified impact of international terrorism on civil liberties suggests an extended “state of emergency” period, as explained by the significant negative initial response, 1–8 years after an international attack occurs. Contrarily, we provide evidence for increased respect for civil liberties 2–10 years after an international attack occurs in authoritarian settings. The estimated effect appears to be non-negligible and robust across various specifications.

在本文中，我们使用跨国数据集评估了 1972 年至 2018 年国际恐怖主义对目标国家公民自由的影响。为了解决攻击前动态的选择和控制问题，我们使用潜在结果框架来揭示治疗随时间对结果变量的影响。在民主国家，公民自由在国际恐怖袭击后受到限制。已确定的国际恐怖主义对公民自由的影响表明“紧急状态”期会延长，正如最初的重大负面反应所解释的那样，在国际袭击发生后 1-8 年。相反，我们提供的证据表明，在独裁环境中发生国际袭击 2 至 10 年后，对公民自由的尊重得到了加强。估计的影响在各种规格中似乎都是不可忽略的且稳健的。
