Im Rahmen der Identifikation des betriebsnotwendigen Eigenkapitals nach § 7 Abs. 1 GasNEV/33 StromNEV ist umstritten, inwiefern asymmetrische Kürzungen zulässig sind. Diese entstehen dann, wenn die Regulierungsbehörden eine Vermögensposition auf der Aktivseite als nicht betriebsnotwendig...

Global climate change represents one of the grand societal challenges which policy makers around the world have agreed to jointly tackle it under the Paris Agreement. Henceforth, much research and policy advice has focused on de-veloping model-based scenarios to identify pathways towards...

We propose a difference-in-differences (DiD) approach to estimate the impact of incentives on cost reduction. We show theoretically, and estimate empirically, that German electricity distribution system operators (DSOs) incur higher costs when subject to a lower-powered regulation mechanism. The...

We study how consumer search affects pricing in markets with incumbents and entrants using panel data on German electricity retail markets. Consumers observe the baseline price of the incumbent and decide whether or not to search. Incumbent providers can price discriminate between searching and...

We propose a difference-in-differences (DiD) approach to estimate the impact of incentives on cost reduction. We show theoretically, and estimate empirically, that German electricity distribution system operators (DSOs) pile up more costs in the year used to determine future prices when subject...

The increasing deployment of decentralised rooftop photovoltaic systems (PV systems) and the expected future diffusion of plug-in electric vehicles (PEVs) can have a major influence on the need to expand low-voltage networks in the near future. The associated grid investments are refinanced via...

Germany taxes electricity use since 1999. The government granted reduced rates to energy intensive firms in the industrial sector for addressing potentially adverse effects on firms' competitiveness. Firms that use more electricity than certain thresholds established by legislation, pay reduced...

In the debate on the premature phase-out of nuclear power generation in Germany, there is an intense dispute on the effective operating time for the existing nuclear power plants. This paper addresses the question of how alternative phase-out regulations affect both the magnitude of total...
