In 2011, German police accidentally stumbled upon a previously unknown right-wing extremist group called the National Socialist Underground (NSU). Further investigations implicated the group in previously unexplained murders of mostly ethnically Turkish individuals and in other crimes targeting...

Inequality of opportunity, particularly when overlaid with racial, ethnic, or cultural differences, increases the social distance between individuals, which is widely believed to limit the scope of cooperation. A central question, then, is how to bridge such divides. We study the effects of a...

The assumption that all migrations are permanent, which pervaded the early microdata-based research on immigrant career profiles, is not supported by the empirical evidence. Rather, many - if not most - migrations appear to be temporary. In this paper, therefore, we illustrate the estimation...

During 2022, about eight million Ukrainians were displaced from Ukraine due to the Russian invasion. Whether these individuals will return holds great significance for Ukraine's reconstruction and is pivotal in shaping integration strategies in host countries. We used Facebook ads to recruit a...

Despite intense policy debates, the relationship between social welfare and refugee crime remains understudied. Taking steps to address this gap, our study focuses on Switzerland, where mobility restrictions on exogenously assigned refugees coincide with cantons’ autonomy in setting social...

This paper studies the impact of compulsory schooling on in-school violence using individual-level administrative data matching education and criminal records from Queensland. Exploiting a dropout age reform in 2006, it defines a series of regression-discontinuity specifications. While police...

This paper analyses the effects of education signals for Ethnic Germans and Germans without a migration background (Native Germansʺ). We base our analysis on a sorting model with productivity enhancing effects of education. We compare whether the signalling value differs between the migrants...

After the collapse of the Soviet Union, more than 3 million people with German ancestors immigrated to Germany under a special law granting immediate citizenship. Exploiting the exogenous allocation of ethnic German immigrants by German authorities across regions upon arrival, we find that...

Following the collapse of the Berlin Wall, the birth rate halved in East Germany. Despite their small sizes, the cohorts conceived during this period of socio-economic turmoil were, as they grew up in reunified Germany, markedly more likely to be arrested than cohorts conceived a few years...

The paper analyses the empirical relationship between immigrants and crime using panel data for 391 German administrative districts between 2003 and 2016. Employing different standard panel estimation methods, we show that there is no positive association between the immigrant rate and the crime...
