The Distribution of National Income in Germany, 1992–2019

This paper estimates and analyzes the distribution and composition of pre-tax national income in Germany since reunification, combining personal income tax returns, household survey data, and national accounts. We find that pre-tax national income inequality has increased since the 1990s, though to a lesser extent than suggested by previous studies. Our results draw parallels in top income structure ...

Der Irrweg der Grundsicherung

Härtere Sanktionen, Leistungsentzug, weniger Vermögensschutz: Die neue Grundsicherung wird die Hoffnungen enttäuschen. Es drohen mehr Arbeitslose und höhere Kosten. Viele setzen große Hoffnungen in die geplante Reform des Bürgergelds und die Umbenennung in Grundsicherung. Doch wird die neue Grundsicherung wirklich die Beschäftigung erhöhen, Kosten reduzieren und mehr Gerechtigkeit schaffen? Diese Hoffnungen ...

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 ...

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 ...
