###  **Today's Speaker**

 Carlo Schwarz (Bocconi University, visiting Stanford), "The Effect of Content Moderation on Online and Offline Hate: Evidence from Germany’s NetzDG"

###  **Abstract**

 We study the online and offline effects of content moderation on social media using the introduction of Germany’s "Network Enforcement Act" (NetzDG), which fines social media platforms failing to remove hateful posts. We show that the law transformed social media discourse: posts became less hateful, refugee-related content less inflammatory, and the use of moderated platforms increased. The NetzDG also had offline effects by reducing anti-refugee hate crimes by 1% for every standard deviation in exposure to far-right social media use. The law reduced hate crimes partly by making it harder for perpetrators to coordinate, without changing attitudes toward refugees.

 *Co-sponsored by FAS and IQSS, the Alberto Alesina Seminar on Political Economy supports research-related activities that integrate the study of economics and politics, whether by studying economic behavior in the political process or political behavior in the marketplace. In general, positive political economy is concerned with showing how observed differences among institutions affect political and economic outcomes in various social, economic, and political systems and how the institutions themselves change and develop in response to individual and collective beliefs, preferences, and strategies*.
