Researchers use (quasi-)experimental methods to estimate how shocks affect directly treated firms and households. Such methods typically do not account for general equilibrium spillover effects. I outline a method that estimates spillovers operating among groups of firms and households. I argue...

This paper proposes a new approach to evaluate the macroeconomic effects of the “Hartz IV” reform, which reduced the generosity of long-term unemployment benefits. We propose a model with different unemployment durations, where the reform initiates both a partial effect and an equilibrium...

We develop a model of optimal carbon taxation and redistribution taking into account horizontal equity concerns by considering heterogeneous energy efficiencies. By deriving first- and secondbest rules for policy instruments including carbon taxes, transfers and energy subsidies, we then...

The German law on co-determination at the plant level (Betriebsverfassungsgesetz) stipulates that works councilors are neither to be financially rewarded nor penalized for their activities. This regulation contrasts with publicized instances of excessive payments. The divergence has sparked a...

Our paper analyzes the role of public employment agencies in job matching, in particular the effects of the restructuring of the Federal Employment Agency in Germany (Hartz III labor market reform) for aggregate matching and unemployment. Based on two microeconomic datasets, we show that the...

In the U.S. real estate market, around 30 percent of listed properties remain unsold. We examine whether unsold property listings exert externalities in the housing market. Our study builds on a comprehensive dataset that encompasses residential property listings in Orange County (California)...

We study management practices and performance of public sector organizations in Germany. For a representative sample of municipalities, we provide survey evidence for substantial het-erogeneity in the use of structured management practices. This heterogeneity is not driven by differences across...

The ifo Business Climate Index for Germany is considered as the most important leading indicator for the German economy. Media reports often refer to the mood in German boardrooms. Based on a survey conducted in May 2023, we show that most of the around 9,000 respondents to the monthly ifo...

This paper provides insights into the time-varying dynamics of the German business cycle over the last five decades. To do so, I employ an open-economy time-varying parameter VAR with stochastic volatility, which I estimate by quasi-Bayesian techniques. The reduced-form analysis reveals...

To investigate the effects of reducing the intensity of tracking, this study exploits reforms across German states which combined the two lower secondary school tracks, sometimes additionally offering the possibility to acquire a university entrance qualification. Using a...
