Electricity transmission has become the pivotal industry segment for electricity restructuring. Yet, little is known about the shape of transmission cost functions. Reasons for this can be a lack of consensus about the definition of transmission output and the complexitity of the relationship...

Our survey reviews the theoretical and empirical literature on all alternative policies to promote the deployment of new fiber-based communications infrastructure. Since such investment is expected to induce substantial positive externalities, dynamic efficiency becomes a particularly important...

A broad-scale coverage of new high-speed broadband networks as foreseen by the European Commission still appears to be a rather unrealistic objective in most EU member states without government intervention in terms of funding network deployment in unprofitable areas. We contend, however, that...

Several regulatory authorities have recently allowed competing network operators to co-invest in network infrastructure. With the use of a laboratory experiment, we investigate the impact of co-investments on competition in regulated network industries, particularly in comparison to unilateral...

The economics literature on Net Neutrality (NN) has been largely critical of NN regulation on the basis of theoretical findings that NN violations can be both welfare improving and welfare deteriorating, depending on the circumstances of the case in question. Thus, an ex post competition policy...

In this paper, we study the impact of co-investment by incumbents and entrants on the roll-out of network infrastructures under demand uncertainty. We show that if entrants can wait to co-invest until demand is realized, the incumbents' investment incentives are reduced and total coverage can be...
