This paper studies the influence of interregional inequality within countries on internal conflicts. Regional inequalities are measured by the population-weighted coefficient of variation of regional GDP per capita. As the main innovation, I use a panel data set of country-level regional...

Empirical studies on minimum wages are primarily concerned with employment while their effects on income inequality receive less attention. Yet, a popular argument for a federal minimum wage in Germany is that it will prevent in-work poverty and reduce income inequality. We examine this...

Household debt has increased significantly since the second half of the 20th century, making it one of the cornerstones of household financial behaviour. It is, however, necessary to monitor that indebtedness does not spiral out of control, as it can have negative consequences both at the micro...

The wave of upbeat stories on the developing world's emerging middle class has reinvigorated a debate on how social class in general and the middle class in particular ought to be defined and empirically measured. With the aim of adding clarity to this debate, this dissertation provides a...

We apply recently proposed individual welfare measures in the context of preference heterogeneity, derived from structural labour supply models. Contrary to the standard practice of using reference preferences and wages, these measures preserve preference heterogeneity in the normative step of...

We introduce the give-or-destroy game that allows us to fully elicit an individual s social preference schedule. We find that about one third of the population exhibits both pro-social and anti-social preferences that are independent of payoff comparisons with those who are affected. We call...

This paper analyzes the effect of the introduction of a final withholding tax on capital income on the progression of the German income tax. As previous literature shows, even with synthetic income taxation, tax progression was strongest in the middle of the income distribution, and decreased...

This paper analyzes the evolution of wage inequality and wage mobility separately for men and women in West and East Germany over the last four decades. Using a large administrative data set which covers the years 1975 to 2008, I find that wage inequality increased and wage mobility decreased...

We experimentally investigate the relevance of (asymmetric) outside options in ultimatum bargaining. Building on the generalized equity principle formulated by Selten (1978) we derive three different equity rules. These equity rules can explain 43% of all o ers. Our within-subject design allows...

This paper shows how conflicting normative views of fair contribution rules can be used to design sequential contribution mechanisms to foster human cooperation in heterogeneous populations. Our model predicts that a sequential mechanism which solicits contributions first from wealthy actors...
