We investigate how negatively reciprocal traits of unemployed individuals interact with "sticks" policies imposing constraints on individual job search effort in the context of the German welfare system. For this we merge survey data of long-term unemployed individuals, containing indicators of...

We analyze a labor market program that subsidizes skill-upgrading occupational training for work-ers employed in small and medium sized enterprises. The program covers a substantial share of training costs. Nonetheless, take-up has been low. In an experimental setup, we mailed 10,000 brochures...

We analyze a German labor market program that subsidizes skill-upgrading occupational training for workers employed in small and medium sized enterprises. This WeGebAU program reimburses training costs but take-up has been low. In an experimental setup, we mailed 10,000 brochures to potentially...

This paper studies effects of the introduction of a new digital mass medium on reemployment of unemployed job seekers. We combine data on high-speed (broadband) internet availability at the local level with German individual register data. We address endogeneity by exploiting technological...

We examine whether economic downturns are beneficial to health outcomes of newborn infants in developed countries. For this we use merged populationwide registers on health and economic and demographic variables, including the national medical birth register and intergenerational link registers...

Empirical analyses of twin mortality often use models with dependent unobserved frailty terms capturing genetic and childhood environmental determinants. This ignores that mortality rates can be co-dependent due to bereavement effects, i.e. to a time-dependent causal effect of the loss of the...

Causal effects of a policy change on the hazard rates of a duration outcome variable are not identified from a comparison of spells before and after the policy change when there is unobserved heterogeneity in the effects and no model structure is imposed. We develop a discontinuity approach that...

We structurally estimate an equilibrium search model using German administrative data and use this for counterfactual analyses of a uniform minimum wage. The model with worker and firm heterogeneity does not restrict the sign of employment effects a priori and allows for different job offer...
