Politicians and police in the face of democratic change in Chile and Colombia
Nowcasting Daily Population Displacement in Ukraine through Social Media Advertising Data
In times of crisis, real-time data mapping population displacements are invaluable for targeted humanitarian response. The Russian invasion of Ukraine on February 24, 2022, forcibly displaced millions of people from their homes including nearly 6 million refugees flowing across the border in just a few weeks, but information was scarce regarding displaced and vulnerable populations who remained inside Ukraine. We leveraged social media data from …
On the effect of the New Year's Eve sexual assaults on anti-refugee violence
In their comment on my 2020 ESR article, Schwitter and Liebe suggest that the increase in anti-refugee attacks following the 2015 New Year's Eve sexual assaults (NYE) could be due to a simultaneous broadening of the German Federal Criminal Police Office definition of anti-refugee violence. I address Schwitter and Liebe's concerns by (i) removing attacks that were included because of the new definition and (ii) restricting the analysis to attacks …
Learning loss due to school closures during the Covid-19 pandemic
Significance School closures have been a common tool in the battle against COVID-19. Yet, their costs and benefits remain insufficiently known. We use a natural experiment that occurred as national examinations in The Netherlands took place before and after lockdown to evaluate the impact of school closures on students’ learning. The Netherlands is interesting as a “best-case” scenario, with a short lockdown, equitable school funding, and world-l…
Getting under the Skin
There is growing academic interest in examining how terrorist attacks shape the majority’s attitudes towards minority groups. Yet, little is known of how these minority groups react to the backlash such events provoke. This paper leverages the exogenous occurrence of a series of terrorist attacks during the fieldwork period of two surveys to estimate how such events affect the sentiment of both citizens and asylum seekers in Germany. Results of t…
The Impact of Mass Shootings on Attitudes toward Gun Restrictions
Is the American public more likely to favor stricter gun legislation in the aftermath of deadly mass shootings? The authors leverage the occurrence of several mass shootings during multiple survey waves of the General Social Survey between 1987 and 2018 to examine whether exposure to a mass shooting sways public opinion on gun legislation. The results reveal that mass shootings increase support for stricter gun permits among Democrats but not for…
Cologne Changed Everything'-The Effect of Threatening Events on the Frequency and Distribution of Intergroup Conflict in Germany
In this article, I study the role that threatening events play in shaping both the occurrence and the distribution of intergroup conflict. Using the case of anti-refugee attacks in Germany, the study finds that the 2015 New Year's Eve (NYE) sexual assaults led to a dramatic surge in the daily rate of violence, far surpassing the more short-lived effect of domestic and European terrorist attacks. Importantly, this effect was more pronounced among …
