A short name is causing a lasting debate: TTIP [tiːt|p]. Ever since the beginning of the negotiations in the summer of 2013, media coverage of the planned Transatlantic Trade and Investment Partnership between the EU and the US has contributed to a critical debate on the topic. In doing so, difficulties have arisen in differentiating factually substantiated arguments from one-sided statements. TTIP ...
This paper evaluates the price effects of the merger of two major U.K. book retailers. We use a dataset containing monthly scanner data on a sample of 200 books in 50 local markets for four years around the merger. We compare the price changes after the merger in shops located in areas where both chains were present before the merger and in areas where only one chain was present. We also investigate ...

Im Rahmen des Projekts DEFINE untersuchen wir die Integration künftiger Elektrofahrzeugflotten in das deutsche Stromsystem für verschiedene Szenarien der Jahre 2020 und 2030 bei unterschiedlichen Ladestrategien. Wir verwenden ein numerisches Kraftwerkseinsatzmodell mit einer Unit‐ Commitment‐Formulierung, bei dem die gesamten Kraftwerkseinsatzkosten über ein komplettes Jahr minimiert werden. Elektrofahrzeugspezifische ...
The “Inclusion of Consumption in EU ETS” is currently gaining traction as a new approach to address carbon leakage and improve the effectiveness of the EU ETS, within legal and political constraints. It complements the current approach of coverage of emissions by upstream installations where trade exposed sectors at risk of leakage, such as steel and clinker, receive free allowances. In order to ensure ...
(together with Markus M. Grabka) Statistical Analysis in surveys is generally facing missing data. In a longitudinal study, when for some missing values past or future data points might be available, the question arises how to successfully transform this advantage into improved imputation strategies. In a simulation study the authors compare six combinations of cross-sectional and longitudinal...

In this study I exploit the exogenous variation in commuting costs brought about by these...
