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...

[Einleitung] Digitalisierung ist wahrlich kein neues Phänomen. Spätestens mit der Dotcom-Euphorie der späten 1990er-Jahre war offensichtlich, dass die Wirtschaft vor einem gewaltigen Umbruch steht. Gut eineinhalb Dekaden später sind Internetkonzerne bereits etablierte Akteure der...

The EU member states have declared to strongly increase the share of Renewable Energy Sources in the next decades. Given a large deployment of wind and solar capacities as well as limited cost-efficient storage technologies, this has two major impacts on electricity systems. First, the...

By 2050, the European Union aims to reduce greenhouse gases by more than 80 %. The EU member states have therefore declared to strongly increase the share of renewable energy sources (RES-E) in the next decades. Given a large deployment of wind and solar capacities, there are two major impacts...

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...

The Fukushima Daiichi nuclear accident in 2011 led to some drastic reactions in Germany, in particular an immediate shut-down of older nuclear power plants. This event is therefore often seen as a turning point, or a major accelerator for the German Energiewende. We investigate the short term...
