Fehr, Mollerstrom and Perez-Truglia (2022) studied individual preferences for policies addressing global inequality by conducting a two-year, face-to-face survey experiment on a representative sample of Germans from the Socio-Economic Panel (SOEP). They found that Germans systematically underestimated their true place in the global income distribution; that these misperceptions were persistent; and ...

This thesis studies the determinants of interethnic relationships between non-migrants and migrants. Theoretically, the thesis builds on the idea that three mechanisms might influence the patterns of relationship formation: opportunities, preferences, and third parties. The introductory part of the thesis reviews the literature in the field. Building on this review, I develop a research agenda. Three ...

On their way to host countries, refugees are often exposed to severe adversity, including cumulative experiences of fraud, extortion, robbery, detention, and shipwrecks, as well as prolonged, life-threatening small boat crossings. However, little research has examined the long-term impact of such peri-migration stressors on subsequent stress and mental health after arrival. This study explored how ...

The integration chances of refugees in their host country are critically shaped by the contextual conditions of the location to which they are assigned upon arrival. Several research groups have developed algorithmic tools to optimize refugee-location matching, with the overall aim of improving refugees’ integration outcomes. These tools are used in a highly sensitive context and thus their design, ...

The new German federal government coalition is planning a significant tax break for workers of retirement age: the active pension (Aktivrente). With the active pension, workers who have reached the statutory retirement age may earn up to 2,000 euros a month tax-free, a move that the government is hoping will motivate more pensioners to work longer to counteract the skilled worker shortage. Microsimulation ...

Motivated by research on gender identity norms and the distribution of the woman’s share in a couple’s total labor income, we consider additive regression models for densities as responses with scalar covariates. To preserve nonnegativity and integration to one under vector space operations, we formulate the model for densities in a Bayes Hilbert space, which allows to not only consider continuous ...

Aktives Management gilt als ein Schlüssel für unternehmerischen Erfolg. Allerdings wurde die Bedeutung von Managementpraktiken bislang ausschließlich für große und mittlere Unternehmen untersucht. Neue Daten aus dem Sozio-oekonomischen Panel (SOEP) ermöglichen nun erstmals eine Analyse für kleine und kleinste Unternehmen (KKU) in Deutschland. Die Ergebnisse zeigen zum einen, dass Kernaktivitäten, wie ...
