This report describes the subject, design and realization of the study "Entscheidungsträger in Deutschland: Werte und Einstellungen". The survey focusses on political attitudes, behavioral norms, motives and biographies of leaders in politics, public administration, business as well as in the...

This study analyses the impact of a high-profile crime event on perceived public safety. At the 2015 New Year's Eve celebrations in Cologne (NYE), Germany, refugees allegedly committed over a thousand crimes, ranging from theft to sexual assault. The widespread media coverage of these incidents...

This study deals with the impact of the 2015 European Refugee Crisis on the ethnic identity of resident migrants in Germany. To derive plausibly causal estimates, I exploit the quasiexperimental setting in Germany, by which refugees are allocated to different counties by state authorities...

Taxpayers often view tax rules and filing processes as complicated. In this paper I study whether the perceived tax uncertainty among peers leads to a reduction of voluntary tax compliance. I find strong supportive evidence for this hypothesis using a survey experiment for a large representative...

This paper studies the effect of immigrants' national identity on integration in an inter-generational context. Economic theory predicts that the origin country identity of immigrants affects their children's integration through its effects on social network choices and incentives to invest in...

I empirically assess the importance of socially interdependent origin cultures as opposed to socially independent ones for network effects in inter-national migration.

In this paper we deliver first causal evidence on the relationship between immigrant host country language proficiency and homeownership. Using an instrumental variable strategy, we find a substantial positive impact of language skills on the propensity to own a home and the quality of housing....

This study presents descriptive and causal evidence on the role of the social environment in shaping the accuracy of self-assessment. We introduce a novel incentivized measurement tool to measure the accuracy of self-assessment among children and use this tool to show that children from high...

Interactions between players with private information and opposed interests are often prone to bad advice and inefficient outcomes, e.g. markets for financial or health care services. In a deception game we investigate experimentally which factors could improve advice quality. Besides advisor...
