This paper examines the causal effect of volume on outcome on the example of patients with a hip fracture. We use an instrumental variable approach and consider both the practice-makes-perfect and selective-referral hypothesis as well as unobserved patient heterogeneity. Our results indicate...

This paper analyses the causal effects of educational mismatch on wages, individual health and job satisfaction. As educational mismatch is subject to unobserved heterogeneity in all of these fields, different identification strategies are applied to derive causal effects. In the wage...

This paper makes use of Hierarchical Bayes Models to model and estimate spatial health effects. We focus on Germany, combining rich individual-level household panel data with administrative county level information to estimate spatial county-level health dependencies. As dependent variable, we...

We apply recently proposed individual welfare measures in the context of preference heterogeneity, derived from structural labour supply models. Contrary to the standard practice of using reference preferences and wages, these measures preserve preference heterogeneity in the normative step of...

This paper uses a rich dataset derived from a three-year survey to gain insights about the informational background of University applicants. We analyze the extent to which students expectations of their starting and future salary depend on different characteristics. More precisely, the paper...

Motivated by the observation that access to evasion opportunities is distributed heterogeneously across the labor market, this paper examines the extent to which labor supply elasticities with respect to tax rates depend on such evasion opportunities. We first discuss the channels through which...

This paper analyzes the effect of the introduction of a final withholding tax on capital income on the progression of the German income tax. As previous literature shows, even with synthetic income taxation, tax progression was strongest in the middle of the income distribution, and decreased...

This paper analyzes revenue and welfare effects of implementing a FAT both from a theoretical and a quantitative perspective. The theoretical analysis allows us to derive expressions for the revenue effects and the deadweight loss in a general equilibrium setting, which can be quantified with a...
