Schulen tragen nicht zu den im Moment steigenden Corona-Fallzahlen bei. Das Wiederöffnen der Schulen nach den deutschen Sommerferien trug vermutlich sogar dazu bei, dass die Inzidenzzahlen niedriger geblieben sind, als sie bei geschlossenen Schulen gewesen wären. Die obligatorischen...

We use event-study models based on staggered summer vacations in Germany to estimate the effect of school re-openings after the summer of 2021 on the spread of SARS-CoV-2. Estimations are based on daily counts of confirmed coronavirus infections across all 401 German counties. Our results are...

We study the impact of short-term exposure to ambient air pollution on the spread and severity of COVID-19 in Germany. We combine data on county-by-day level on confirmed cases and deaths with information on local air quality and weather conditions and exploit short-term variation in the...

This paper studies health effects from restricting the access of high-emission vehicles to innercities by implementing low emission zones. For identification, we exploit variation in the timing and the spatial distribution of the introduction of new low emission zones across cities in Germany....

This paper studies the effect of the end of school summer breaks on SARS-CoV-2 cases in Germany. We exploit variation in the staggered timing of summer breaks across federal states which allows us to implement an event study design. We base our analysis on official daily counts of confirmed...

This paper studies whether people's perception of improvements in local air quality are reflected in the housing market based on comprehensive data on real estate prices from Germany. Using a quasi-experimental research design, we exploit the staggered introduction of Low Emission Zones (LEZs)...
