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...

The liberalization of telecommunications is largely based on the premise that increasing competition will encourage investment. The hypothesis that liberalization promotes investment has received the most empirical support in recent research. However, a key question that has been largely ignored...

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...

The purpose of this Paper is to study the determinants of the concentration of ownership in a privatized, regulated firm. The discussion illustrates some aspects of the costs and benefits of different corporate systems. Privatized utilities are large firms with professional management: there is...

This study analyzes the interaction of agency problems in public policy and of agency problems inside the firm: it investigates the case of a large privatized firm subject to many policy constraints. The last steps of Telefonica's privatization were designed to promote a disperse ownership and...

The next years should bring about a rapid transformation of the electricity sector towards high levels of renewable generation. Smart grids are seen as the silver bullet responding to the challenge of integrating renewables, managing flexibility, and keeping the costs down in distribution...

In this article, I analyze and compare the contributions of Dupuit and Walras on the natural monopoly of railroads. Both theorists argued that inland waterways—as opposed to railroads—could be vertically unbundled, a point which previous authors who compared their views failed to point out....

The question of third-party access to the networks has become central to the debate around the liberalisation of the European electricity markets due to the natural monopoly characteristic of the transmission network. The European Union?s electricity directive provides three institutional...

The paper considers price trends as signals for the evaluation of reforms leading to ownership or market structure changes in public services. In order to do so, we focus on a specific example: electricity prices in four countries, namely UK, France, Germany and Italy.We consider that these...

In this paper we estimate the benefits resulting from interconnecting the Italian electricity spot market. The market is currently divided into two geographic zones – North and South – with limited interzonal transmission capacity that often induces congestion, and hence potential...
