Automated emotion recognition in marketing research: A systematic literature review of current image and video-based methods

This study reviews the recent literature on Automated Emotion Recognition (AER), focusing on image and video-based methods applied in marketing research. The literature overview highlights the transformative potential of AER, including real-time, unobtrusive, and scalable applications. It identifies key tools, including Noldus' FaceReader and iMotions' Facial Expression Analysis, as significant contributors to insights in diverse contexts such as e-commerce, social media, and online platforms. The analysis also addresses theoretical challenges, such as the limitations of Ekman's basic emotion theory and the contextual dependence of facial expressions. Practical recommendations for AER use include incorporating multimodal approaches and ensuring cultural and contextual inclusivity in training datasets. Thus, the current work advances the discourse on leveraging AER for refined marketing strategies.

The 2015/2016 New Year’s Eve Cologne Event and Anti-refugee Crimes in Germany

During New Year’s Eve 2015/2016, the German city of Cologne witnessed mass sexual assaults and thefts by perpetrators described as having an Arab-African appearance. This paper studies whether the event in Cologne led to a backlash in crimes against refugees in Germany. Difference-in-differences regressions reveal a significant jump in anti-refugee crimes immediately after the event. This rise is driven by assaults and miscellaneous crimes and is more pronounced in North Rhine-Westphalia (where Cologne is located), in wealthier counties, in counties with a higher share of refugees, and in the counties that had a refugee reception center. The immediate rise in anti-refugee crimes is also higher in counties where a higher share of German suspects has been involved in crimes against foreign victims. Regarding longer-term repercussions, I find evidence for an anniversary effect a year later, i.e., a rise in anti-refugee crimes after the next New Year’s Eve.
