Die Konzentration im deutschen Lebensmitteleinzelhandel schreitet weiter voran und rückt das Thema Nachfragemacht mehr und mehr in den Fokus wettbewerbspolitischer Diskussionen. Im Gegensatz zur Angebotsmacht liegen gesicherte empirische Erkenntnisse über das Vorhandensein, das Ausmaß und die Folgen von Nachfragemacht auf den Beschaffungsmärkten des Lebensmitteleinzelhandels in Deutschland bislang ...
We apply the EMF 23 study design to simulate the effects of the reference case and the scenarios to European natural gas supplies to 2025. We use GASMOD, a strategic severallayer model of European gas supply, consisting of upstream natural gas producers, traders in each consuming European country (or region), and final demand. Our model results suggest rather modest changes in the overall supply situation ...
We analyze distinctive investment scenarios for the integration of fluctuating renewables in the German power system. Using a combined model for dispatch, transmission, and investment, three different investment options are considered, including gas-fired power plants, pumped hydro storage, and transmission lines. We find that geographically optimized power plant investments dominate in the reference ...
We analyze a client's choice of contract in auctions where Dutch law firms compete for cases. The distinguishing feature is that lawyers may submit bids with any fee arrangement they prefer: an hourly rate, a fixed fee or a \mixed fee," which is a time-capped fixed fee plus an hourly rate for any additional hours should the case take longer than expected. This format of selling legal services is unusual ...
The energy efficiency of the residential housing stock plays a key role in strategies to mitigate climate change and global warming. In this context, it is frequently argued that private investment and the quality of thermal upgrades is too low in the light of the challenges faced and the potential energy cost savings. While many authors address the potential barriers for investors to increase energy ...
In this paper we investigate natural gas producer's reactions to changes in market prices. We estimate price elasticities of aggregated supply in the most competitive market for natural gas: the United States. Using monthly time series data form 1987 to 2012 our analysis is based on an Autoregressive Distributed Lag (ARDL) Bound Cointegration approach to obtain short and long-run elasticities of natural ...
