We examine how vertical separation affects the lobbying activities for the access charge of essential facilities. First, when investigating a model where the number of new entrants is fixed, we find that vertical separation either increases or decreases the access charge, and that this depends...

We examine incentives of bottleneck facility holders to manipulate access charge accounting in free entry downstream markets. We consider the situation wherein one firm holds an upstream bottleneck facility and new entrants use it at the regulated price (access fee) to provide final products....

Der in Gang befindliche Übergang von den klassischen Telekommunikationsnetzen zu "Next Generation Networks" bietet zwar hohe Innovationspotenziale, es besteht aber auch die Gefahr, dass marktmächtige Netzbetreiber ihre dominanten Positionen auf die bisher wettbewerblichen Märkte für...

This paper analyzes how competition works in mobile telecommuncations markets and, bases on this analysis, we discuss whether regulatory intervention in mobile telephone markets is justified from an economic perspective. Starting point of our analysis is the observation that an evaluation of...

This paper experimentally studies the role of search cost in duopoly markets where sellers may be able to coordinate pricing decisions. We vary the level of search cost and whether sellers can communicate. While we find that consumers are more likely to invest in search when cost is reduced, we...

Despite the positive effect electricity grids separated from generation and supply by ownership are expected to have on the level of competition in the non-network activities, several EU member states still adhere to a solely legally unbundled transmission grid. This choice might be induced by...
