Wage Risk and Portfolio Choice: The Role of Correlated Returns

From standard portfolio-choice theory, it is well-understood that background risk, primarily due to wage risk, is one of the central determinants of individuals’ portfolio composition: higher background risk reduces risky investments. However, if background risk is negatively correlated with financial market risk, higher background risk implies a more risky investment. We quantify the influence of ...

Does Cognitive Reflection Relate to Preferences and Socioeconomic Outcomes?

Previous studies report associations of cognitive reflection, the ability to avoid intuitive but potentially wrong decisions by switching to a contemplative mindset, with individual preferences, mostly relying on student samples and laboratory settings. We assess the association of cognitive reflection with preferences in the general population and real-world socioeconomic outcomes. Our preregistered ...

Is the First Language a Resource, an Obstacle, or Irrelevant for Language Minority Students’ Education?

Successful integration into the education system is of major importance for the future prospects of immigrants and their children as well as for the social cohesion and viability of the receiving societies. Language is generally viewed as an important aspect of this integration. Whereas there is widespread agreement that the language of the residence country (L2) is crucial for students’ educational ...

Evaluating Sampling Methods for Ethnic Minorities

Ethnic minorities are often underrepresented in survey research, due to the challenges many researchers face in including these populations. While some studies discuss several methods in comparison, few have directly compared these methods empirically, leaving researchers seeking to include ethnic minorities in their studies unsure of their best options. In this article, I briefly review the methodological ...

The Power of Stereotypes and how they influence labour market outcomes (with Susanne Veit and Johanna Hildebrandt)

In this paper, we draw on two key models of stereotyping, the Stereotype Content Model (SCM) and the Agency-Beliefs-Communion (ABC) to study whether stereotypes associated to ethnic minorities predict discrimination in hiring in the German labor market. In study 1, we examined the content of the stereotypes that Germans ascribe to 38 ethnic minorities, drawing on a large-scale online survey (N=2,3...

Unequal Estate Division for Wealth Perpetuation: Portfolios, Primogeniture, and Patrilineality (with Daria Tisch and Manuel Schechtl)

While inequalities in inter-vivos gifts and bequests between families are widely recognized as key drivers of wealth inequality, less is known about the unequal transmission of wealth within families. This study addresses this gap by asking: (1) To what extent are estates unequally divided? (2) How do estate portfolios, primogeniture, and patrilineality shape unequal estate division? (3) What is...

Narratives on the Distributional Impact of Climate Policy Can Fuel Populism

Populist parties use narratives about social injustice to portray climate policy as elite-driven and socially unjust. This study— based on a survey experiment with some 1,600 participants— examines how three common narratives about the costs associated with climate policy affect populist and climate-populist attitudes. The results show that the narrative highlighting the disproportionate burden on ...
