The comprehensive theoretical literature on mobile termination rates (MTRs) is inconclusive on how the level of MTRs affects overall consumer charges and firms’ profit. In a theoretical model, well suited for econometric implementation, we show that where consumers buy a bundle with included...

Text messaging has become an important revenue component for European and Asian mobile operators. We develop a simple model of demand for mobile services incorporating the existence of call externalities and network effects. We show that when incoming messages and calls stimulate outgoing...

We consider two different qualities of broadband access, one that simply means greater access speed to Internet applications and content, and a premium version that also gives access to interactive TV services. Based on a market survey we find that potential consumers of this premium broadband...

According to the new European telecom regulation, incumbent operators are required to provide access to such bottlenecks on fair, reasonable and non-discriminatory terms. We explore different interpretations of this general rule in a model in which the bottleneck can be used by external (to the...

We analyze competition between two horizontally differentiated network providers. New technologies help the providers to collect consumer-specific information, and such technologies increase the providers' ability to use price discrimination. One example is the mobile providers' choice of...

We analyze an endogenous average cost based access pricing rule,where both the regulated firm and its rivals realize the interdependence among their output and the regulated access price. In contrast, the existing literature on access pricing has always assumed the access price to be exogenously...

In a Hotelling duopoly model, we introduce quality that is more appreciated by closer consumers. Then higher common quality raises equilibrium prices, in contrast to the standard neutrality result. Furthermore, we allow consumers to buy one out of two goods (single-purchase) or both...
