To determine how wives' and husbands' retirement options affect their spouses' (and their own) labour supply decisions, we exploit (early) retirement cutoffs by way of a regression discontinuity design. Several German pension reforms since the early 1990s have gradually raised women's retirement...

We document the educational integration of immigrant children with a focus on the link between family size and educational decisions and distinguishing particularly between first- and second-generation immigrants and between source country groups. First, for immigrant adolescents, we show...

We evaluate the effects of a reduction in sick pay from 100 to 80% of the wage. Unlike previous literature, apart from absence from work, we also consider effects on doctor/hospital visits and subjective health indicators. We also add to the literature by estimating both switch-on and switch-off...

A popular argument for a federal minimum wage is that it will prevent in-work poverty and reduce income inequality. We examine this assertion for Germany, a welfare state with a relative generous means-tested social minimum and high marginal tax rates. Our analysis is based on a microsimulation...

We study three budget-neutral reforms of the German tax and transfer system designed to improve work incentives for people with low incomes: a feasible flat tax reform that provides a basic income which is equal to the current level of the means tested unemployment benefit, and two alternative...

We investigate how personal income taxes affect the portfolio share of personal wealth that entrepreneurs invest in their own business. In a reformulation of the standard portfolio choice model that allows for underreporting of private business income to tax authorities, we show that a fall in...

We analyze the effects of three alternative proposals to reform the taxation of families relative to the current German system of joint taxation of couples and child allowances: a French-type family splitting and two full family splitting proposals. The empirical analysis of the effects of these...

We analyse benefit-entitlement effects and the likely impact of the recent reform of the unemployment compensation system on the duration of unemployment in Germany on the basis of a flexible discrete-time hazard rate model estimated on pre-reform data from the German Socioeconomic Panel. We...

We analyze the distribution and concentration of market incomes in Germany in the period 1992 to 2001 on the basis of an integrated data set of individual tax returns and the German Socio-Economic Panel. The unique feature of this integrated data set is that it encompasses the whole spectrum of...
