Does Size Matter? The Impact of Changes in Household Structure on Income Distribution in Germany

Income inequality in Germany has been continually increasing during the past 20 years. One cause of this development, among others, could be structural shifts in household formation due to long-term societal trends. These affect per capita incomes, which has repercussions for the income distribution even if wages remain constant. The aim of this paper is to quantify the proportion of changing household ...

Bemessungsgrundlage kontra Fünf-Stufen-Tarif: Eine Simulationsanalyse des Reformvorschlags nach Rose

Die Komplexität des deutschen Steuersystems hat in den vergangenen Jahren immer wieder Kritik hervorgerufen und zu verschiedenen Verbesserungsvorschlägen geführt, von denen jedoch bislang noch keiner ungesetzt wurde. Denn um eine breite politische Akzeptanz zu erlangen, müssen Reformvorschläge zum Steuersystem neben Transparenz und Einfachheit gleichzeitig sicherstellen, dass die Einkommensungleichheit ...

Reform der Hartz IV-Hinzuverdienstregelungen: Ein verfehlter Ansatz

In Germany, both policy makers and researchers have been searching for solutions to overcome the disincentives on labor supply generated by income allowances for welfare recipients (Unemployment Benefit II). Taking proposals of the German Economic Institute (IW) and the governing Liberal Party (FDP) as a starting point, the German Federal Government has intensely discussed this topic during fall 2010 ...

The Politicians’ Wage Gap: Insights from German Members of Parliament

Using a unique dataset of German members of parliament with information on total earnings including outside income, this paper analyzes the politicians’ wage gap (PWG). After controlling for observable characteristics as well as accounting for selection into politics, we find a positive PWG which is statistically and economically significant. It amounts to 40-60% compared to citizens with an executive ...

Wie progressiv ist Deutschland? Das Steuer- und Transfersystem im europäischen Vergleich

Measuring Richness and Poverty: A Micro Data Application to Europe and Germany

In this paper, we define a new class of richness measures. In contrast to the often used headcount, these new measures are sensitive to changes in rich individuals' incomes and, therefore, allow for a more sophisticated analysis of richness. We demonstrate the application of these new measures in analyzing the development of poverty and richness over time in Germany. Moreover, we compare Germany ...

IZAΨMOD consists of three components: First, a static module simulates the effects of a tax reform on the budget of the individual households. Secondly, ...

Accounting for Labor Demand Effects in Structural Labor Supply Models

When assessing the effects of policy reforms on the labor market, most studies only focus on labor supply. The interaction of supply and demand side is not explicitly modeled, which might lead to biased estimates of potential labor market outcomes. This paper proposes a straightforward method to remedy this shortcoming. We use information on firms’ labor demand behavior and feed them into a structural ...

Accounting for the Spouse when Measuring Inequality of Opportunity

The existing literature on inequality of opportunity (IOp) has not addressed the question of how the circumstances and choices of spouses in a couple should be treated. By omitting information relevant to the spouse in IOp estimations, the implicit assumption has been full responsibility for the spouse’s income, effort and circumstance variables. In this paper, we discuss whether or not the spouse’s ...
