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...

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...

An important goal when analyzing the causal effect of a treatment on an outcome is to understand the mechanisms through which the treatment causally works. We define a causal mechanism effect of a treatment and the causal effect net of that mechanism using the potential outcomes framework. These...

Im populären und politischen Diskurs werden häufig ökonomische Verhältnisse (wie Armut, Ungleichheit oder Wachstumsschwäche) als Gründe für die Entstehung und den Export von Terrorismus aus ärmeren Ländern genannt. Zugleich gelten wirtschaftlich erfolgreiche Staaten häufig als Ziele...

Freiwilliges Engagement findet in Deutschland in einem breiten Spektrum von Bereichen und Tätigkeitsfeldern statt. Gleichzeitig ist aber über die Tätigkeiten, die freiwillig Engagierte ausüben und deren quantitative Verteilung wenig bekannt. Dieser Beitrag verfolgt daher das Ziel, die...

Bisherige Studien haben gezeigt, dass ethnische Bildungsungleichheiten bereits vor der Einschulung entstehen. Es wurde gezeigt, dass insbesondere für Lernende mit Migrationshintergrund eine frühe Bildungsbeteiligung einen positiven Einfluss auf die späteren Bildungsergebnisse hat, wobei der...

Intra-household inequality explains up to 50 percent of the cross-sectional variation in child human capital in the developing world. I study the role played by parents' educational investment to explain this inequality and its determinants. To mitigate the identification problem posed by...
