In January 2005, the German government enacted a substantial reform of the welfare system, the so-called Hartz IV reform. This book evaluates key characteristics of the reform from a microeconometric perspective. It investigates whether a centralized or decentralized organization of welfare...

We develop a nonparametric instrumental variable approach for the estimation of average treatment effects on hazard rates and conditional survival probabilities, without model structure. We derive constructive identification proofs for average treatment effects under noncompliance and dynamic...

We study state dependence in the German welfare system and compare transition patterns before and after recent reforms of the welfare system (Hartz Reforms). Using data from the German Socio-Economic Panel, we apply dynamic multinomial logit estimators and find that welfare transitions have...

We evaluate the quantity-quality trade-off on the labor market by estimating an augmented matching function weighting the matches by quality measures. We use the approach to evaluate the German labor market reforms conducted between 2003 and 2005. Indeed, we find a significant quantity-quality...

In 2005, the unemployment benefits for long-term unemployed were reduced in Germany. We investigate the effect of this reform on the transition probability from unemployment to employment using a large German administrative spell data set (SIAB 1975 - 2010). We estimate that the daily transition...
