Policymakers have implemented a wide range of non-pharmaceutical interventions to fight the spread of COVID-19. Variation in policies across jurisdictions and over time strongly suggests a difference-in-differences (DD) research design to estimate causal effects of counter-COVID measures. We...

With the expansion of onshore wind power, countries increasingly consider the introduction of minimum distance regulations between wind turbines to nearby residential areas, to increase public acceptance. In 2014, the German federal state of Bavaria introduced a minimum distance regulation that...

One of the perceived advantages of difference-in-differences (DiD) methods is that they do not explicitly restrict how units select into treatment. However, when justifying DiD, researchers often argue that the treatment is "quasi-randomly" assigned. We investigate what selection mechanisms are...

Decarbonizing the global energy matrix through investments in renewable energy (RE) is considered a pathway to mitigate the effects of global climate change. Auctions have become an increasingly popular policy instrument for this purpose. In the last few years, auctions have been rapidly adopted...

Eine wichtige zwischen den Bundesländern variierende schulrechtliche Regelung ist die Verbindlichkeit der Schullaufbahnempfehlung beim Übergang von der Grundschule auf die weiterführenden Schulen. Während sie in einigen Bundesländern bindend ist, wird in anderen Bundesländern den Eltern...

We develop a multiple-events model and exploit within and between country variation in the timing, type and level of intensity of various non-pharmaceutical interventions to study their dynamic effects on the daily incidence of COVID-19 and on population mobility patterns across 135 countries....

Early non-pharmaceutical interventions (NPI) significantly reduced the death toll of the Covid-19 pandemic. Yet, there are vast differences in how quickly governments implemented NPIs. In this paper, we analyze the role of public attention, measured as the share of daily Google searches in a...

This study documents how the demographics of new infections and mortality changed over time across US counties. We find that counties with a larger population share aged above 60 were hit harder initially in terms of both cases and mortality in March and April while counties with a larger...
