Individuals vary considerably in how much they earn during their lifetimes. This study examines the role of the tax-and-transfer system in mitigating such inequalities, which could otherwise lead to disparities in living standards. Utilizing a life-cycle model, we determine that taxes and...

Deploying data from the German Socio-Economic Panel (GSOEP) we analyze the variability of individual earnings and equivalent household income. Permanent and transitory variances of male income over the period 1984-2008 are estimated for Old German Laender in order to determine their importance...

Ungleichheitsstudien basieren in der Regel auf Daten zu Jahres- oder Monatseinkommen, um die Verteilung ökonomischer Ressourcen zu einem bestimmten Zeitpunkt im Querschnitt einer Bevölkerung zu bestimmen. Analysen auf Jahres- oder Monatsquerschnitten können jedoch ein unvollständiges Bild...

Individuals vary considerably in how much they earn during their lifetimes. We study how the tax-and-transfer system o sets inequalities in lifetime earnings, which would otherwise translate into differences in living standards. Based on a life-cycle model, we find that redistribution by taxes...

The rational expectations assumption, e.g. in life-cycle models and portfolio-choice models, prescribes agents to have model-consistent beliefs and to avoid systematic prediction errors. In reality, justi cation and identification of expectations are nontrivial. One way to solve this problem is...

We study the dynamics of capital accumulation, income inequality, capital concentration, and voting up to 1914. Based on new panel data for Prussian regions, we re-evaluate the famous Revisionism Debate between orthodox Marxists and their critics. We show that changes in capital accumulation led...

Wage growth occurs almost exclusively in full-time work, whereas it is close to zero in part-time work. German women, when asked to predict their own potential wage outcomes, show severely biased expectations with strong over-optimism about the returns to part-time experience. We estimate a...

The US skill premium and college enrollment have increased substantially over the past few decades. In addition, while low-wage earners worked more than highwage earners in 1970, the opposite was true in 2000. We show that a parsimonious neoclassical model featuring skill-biased technical...

German social security records involve an indicator for part-time or full-time work. In 2011, the reporting procedure was changed suggesting that a fraction of worker recorded to be working full-time before the change were in fact part-time workers. This study develops a correction based on...

This paper assesses the impact of a large expansion of public childcare in Germany on wage inequality. Exploiting regional variation in childcare supply over the 1990s, I show that in regions with stronger increases in childcare, wage inequality among women increased less strongly compared to...
