In dem Paper wird untersucht, wann ein vertikal integrierter Netzbetreiber einen Anreiz hat, durch Fordern hoher Netznutzungsentgelte Wettbewerber vom Strommarkt fernzuhalten (Preisstrukturmißbrauch). Es wird als kontraintuitives Ergebnis abgeleitet, daß ein Kostennachteil des Netzbetreibers...

This paper explores the relation between the regulation of monopolistic upstream prices and the incentives of a vertically integrated input monopolist to discriminate third parties on the downstream market. Currently, this is an issue in network industries like telecommunications, electricity...

We analyze the current regulatory regime for electricity transmission in Germany, which combines network planning with both cost-plus and revenue-cap regulations. After reviewing international experiences on transmission investment, we first make a qualitative assessment of the overall German...

This paper examines how regulatory interventions can affect the market risk of electricity utilities and telecom carriers traded in the Brazilian stock market. Our article uses a bivariate Generalized AutoRegressive Conditional Heteroskedasticity (GARCH - BEKK) model to analyze the impact of two...

This paper presents a general electricity-CO2 (ELCO) modeling framework that is able to simulate interactions of the energy-only market with different forms for national policy measures. We set up a two sector model where players can invest into various types of generation technologies including...

The European Commission is introducing new regulations on submission and publication of data in electricity markets (SPDEM) and on wholesale energy market integrity and transparency (REMIT). I discuss issues relevant for undertaking an evaluation such regulations. I argue that, for market...

Drei Jahre nach der Atomkatastrophe im japanischen Fukushima rücken Laufzeitverlängerungen bestehender Kernkraftwerke und der Bau neuer Reaktoren weltweit wieder stärker in den Fokus. Befürworter erhoffen sich eine kostengünstige Stromerzeugung, eine sichere Energieversorgung sowie einen...

Subsidies to renewable energy are costly and contentious. We estimate the reduction in prices that follows from the subsidized entry of wind power in the Nordic electricity market. A relatively small-scale entry of renewables leads to a large-scale transfer of surplus from the incumbent...

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...

Extending the power grid into hitherto unconnected areas is high on the policy agenda in Sub-Saharan Africa. Yet, connection rates and electricity consumption remain low in grid connected areas, at least in the short and medium run. This paper provides a long-term follow-up on an evaluation of a...
