Modeling Public Policy: Influences on Terrorism and Public Opinion

This article examines the effects of counterterrorism policy in Canada, the United States, and the United Kingdom between 1997 and 2016. We use time series analysis and series hazard models to examine the influence of policy on (a) incidents of terrorist violence and (b) citizen perceptions of the threat of terrorism. Results indicate that counterterrorism policy is, for the most part, not related to significant changes in Canada but does report significant results for public opinion and terrorist incidents in the United States and the United Kingdom, although these effects are temporally defined.
