Navigating Potential Pitfalls in Difference-in-Differences Designs: Reconciling Conflicting Findings on Mass Shootings’ Effect on Electoral Outcomes –
Research on the electoral impacts of gun violence in the U.S. has yielded varying findings, with some studies indicating significant effects while others suggest negligible results. This article discusses the popular use of difference-in-differences models in analyzing these effects, spotlighting prevalent methodological issues such as violations of parallel trends and treatment effect heterogeneity. The authors, Hans J. G. Hassell and John B. Holbein, contend that many studies overstating the positive effect of gun violence on Democratic votes fail to accurately specify their models amidst these issues. Upon correcting biases, evidence indicates minimal electoral changes triggered by mass shootings. This analysis not only clarifies ongoing debates but also serves as guidance for researchers employing these designs.
