Hybrid governance structures between markets and hierarchies in many industries, e.g., in energy and telecommunications, challenge antitrust and regulation policy. The paper focuses on the theoretical and methodological basis provided by the New Institutional Economics (NIE) for analyzing the...

In the EU electricity industry, many Vertically Integrated Utilities (VIUs) have ownership both of electricity generators and of transmission, hence VIU-owned or allied generators often are bidders in auctions for VIU-owned transmission. In Van Koten (2006) I show that welfare suffers and the...

Despite efforts made by European Commission to liberalize electricity markets and foster integration, there are still significant barriers to free competition. Until now, Romania was one of the countries that have been compliant to the European Union's electricity directives, being ahead of...

Power market integration is analyzed in a two countries model with nationally regulated firms and costly public funds. If generation costs between the two countries are too similar negative business-stealing outweighs efficiency gains so that following integration welfare decreases in both...

The aim of this paper is to give deeper insights into the impact of regulatory reforms and privatization on R&D spending of electricity utilities. Building on a panel data set including the biggest European utilities from eight EU-countries over a period from 1985 until 2010, we find a strong...

The commercial value added in electricity distribution networks and smart grids is increasing. Concerns about competition on a level-playing field are raised and the debate on vertical network unbundling is beginning to address the level of the distribution networks. With regard to the...

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...

Retail electric deregulation has been identified in the literature to have favorable price impacts to businesses and households because of the introduction of competition into rate-setting. Those studies often ignore the important role of regulatory intervention. They are also generally national...
