The German Energiewende’s potential effects on the reliability of electricity supply as well as the corresponding economic consequences have recently entered both the political and scientific debate. However, empirical evidence of power outage costs in Germany is rather scarce. Following a...

In this paper, we conduct a pan-European efficiency analysis to investigate the performance of European railways with a particular focus on economies of vertical integration. We test the hypothesis that integrated railways realize economies of scope and, thus, produce railway services with a...

In the course of railway reforms in the end of the last century, national European governments, as well the EU Commission, decided to open markets and to separate railway networks from train operations. Vertically integrated railway companies - companies owning a network and providing transport...

Since the 1990s, efficiency and benchmarking analysis has increasingly been used in network utilities research and regulation. A recurrent concern is the effect of environmental factors that are beyond the influence of firms (observable heterogeneity) and factors that are not identifiable...

Levels of CO2 emissions from electricity generation in the U.S. have changed considerably in the last decade. This development can be attributed to two factors. First, the shale gas revolution has reduced gas prices significantly, leading to a crowding out of the more CO2-intensive coal for...

In this article, we analyze the relative CO2 emission performance across 48 states in the U.S. using a two-stage empirical approach. In the first stage, we identify the states that followed best practice by applying benchmarking techniques. In the second stage, we regress our CO2 emission...

With an ongoing energy transition, the electric network is increasingly challenged. Handling congestion is a major responsibility of network operators. In recent years, market-based approaches to utilize network-supportive exibility, especially local exibility markets (LFMs), have been discussed...

Das Jahr 2021 hat in Deutschland neuen Schwung in die Bemühungen zum Klimaschutz gebracht. Die Novelle des Klimaschutzgesetzes schreibt eine Reduktion der Treibhausgasemissionen um 65 % bis zum Jahr 2030 gegenüber 1990 fest. Maßgeblich dazu beitragen soll ein massiver Ausbau der...
