In the course of the 1990s, the EU has embarked on an ambitious regulatory reform programme for a number of European network industries, such as telecommunications, energy and transport. This paper analyses the potential benefits of successful reforms in these sectors with a focus on the price...

Reviewing the development of network access charges in the German electricity market since 2002 reveals significant variation. While some firms continually increased or decreased their access charges, a variety of firms exhibited discontinuous behavior with price changes in both directions. From...

In the past two decades privatisation and liberalisation of network industries providing services of general economic interest (SGEI), have been particularly significant in the European Union. Wide variations around a common policy trend can, however, be observed across countries and sectors. We...

Im Zuge der Diskussion über die Liberalisierung des deutschen Strommarktes wurde von kommunaler Seite die Befürchtung vorgebracht, daß die Einführung von Wettbewerb zu einem Rückgang der Gemeindeeinnahmen führe Dieser Beitrag untersucht diese Behauptung aus ökonomischer Sicht. Es zeigt...

It is widely accepted that in liberalized electricity markets log-returns display fat-tailed densities. Besides qualitative assessments, so far precise characterizations of the shape of the distribution have been seldom provided. In this work, we characterize the conditional and unconditional...

The evidence of volatility-price dependence observed in previous works (Karakatsani and Bunn 2004; Bottazzi, Sapio and Secchi 2005; Simonsen 2005) suggests that there is more to volatility than simply spikes. Volatility is found to be positively correlated with the lagged price level in settings where...

The literature on deregulated electricity markets generally assumes available capacities to be given. In contrast, this paper studies a model where firms precommit to capacity levels before competing in a uniform price auction. The analysis sheds light on recent empirical findings that firms use...

This paper presents an ex-post empirical analysis of the impact of European electricity mar- ket refirms on markups ofirms. The working hypothesis is that further economic integration would bring competition into electricity markets re ected by lower markups of electricityfirms. The results show...

We review the recent empirical research concerning market power on the Nordic wholesale market for electricity, Nord Pool. There is no evidence of blatant and systematic exploitation of system level market power on Nord Pool. However, generation companies seem from time to time able to take...
