The outbreak of COVID‐19 has sparked a sudden demand for fast, frequent and accurate data on the societal impact of the pandemic. This demand has highlighted a divide in survey data collection: Most probability‐based social surveys, which can deliver the necessary data quality to allow valid inference to the general population, are slow, infrequent and ill‐equipped to survey people during a lockdown. ...
The European Emissions Trading System (EU-ETS) is the key policy tool of the EU to reduce GHG emissions. To prevent carbon leakage, most of the emission permits have been allocated for free in the industrial sector. A carbon border adjustment mechanism (CBAM) will be introduced end of 2023 as an alternative carbon leakage protection instrument. However, the CBAM will only gradually replace free...
This paper empirically analyses the impact of government ownership on competition in monopoly and duopoly markets. We use the European Airline Industry as a laboratory. In our empirical strategy we exploit two sources of exogenous variations that allow us to cleanly filter out the effect of government ownership on the likelihood of exit. First, we study government ownership that was triggered by a...
Die deutsche Volkswirtschaft bezieht ihre Rohstoffe, gemessen an ihrem Wert, zu 90 Prozent aus dem Ausland. In einer Welt freien und sicheren Handels wäre das kaum eine Notiz wert, doch die Zeiten haben sich bekanntlich geändert. Die proklamierte „Zeitenwende“ bringt es mit sich, dass die bestehende Abhängigkeit Deutschlands von ausländischen Lieferungen neu hinterfragt wird. Es macht einen großen ...

Sociological research is increasingly using panel data to examine changes in diverse outcomes over life course events. Most of these studies have one striking similarity: they analyse changes between yearly time intervals. In this paper, we present a simple but effective method to model such trajectories more precisely using available data. The approach exploits month-specific information regarding ...
We develop a structural vector autoregressive framework that combines external instruments and heteroskedasticity for identification of monetary policy shocks. We show that exploiting both types of information sharpens structural inference, allows testing the relevance and exogeneity condition for instruments separately using likelihood ratio tests, and facilitates the economic interpretation of the ...
