Trotz schrittweiser Erfolge bei der Liberalisierung der europäischen Elektrizitätsmärkte lässt die Wettbewerbsintensität auf den Großhandelsmärkten in vielen Ländern noch zu wünschen übrig. Dementsprechend sind die Preise im Verhältnis zum wettbewerblichen Referenzmaßstab zu hoch....

Prices may differ between regional markets if transport capacities are limited. We develop a new approach to determine to which extent such differences stem from limited participation in cross-border trader rather than from bottlenecks. We derive a theoretical integration benchmark for the...

The supply function equilibrium provides a game-theoretic model of strategic bidding in oligopolistic wholesale electricity auctions. This paper presents an intuitive account of current understanding and shows how welfare losses depend on the number of firms in the market and their asymmetry....

By integrating a communications system with the existing power grid, smart grids provide end-to-end connectivity. This enables all entities and components integrated in the electricity supply system to exchange information without knowing the network's structure. New services and applications...

The purpose of this research is to evaluate the impact of vertical unbundling on German electric utilities. Our research mainly relies on in-depth interviews with sector-experts from the German utilities. We will discuss both short-term changes and the long-term impact on competition in the...

What is a good balance between competition and coordination in network industries? Network unbundling aims to promote competition, but this has to be balanced against the downside of unbundling: firm-internal coordination falls away and must be replaced by external market mechanisms. This is a...

This article examines the energy market restructuring in EU after the gradual liberalisation process of previous years and defines the application of European competition law to this framework of restructuring. We firstly present the different aspects of this restructuring and second we...
