In theory, network profits are independent of the reciprocal termination rates when operators charge nondiscriminatory call prices (Laffont, Rey and Tirole, 1998). Additionally, termination rates can be used to subsidize subscriber acquisition cost. This issue is typically known as a "waterbed...

Introduced in the mobile telecommunications market across world, mobile virtual network operators (MVNOs) are considered an effective way to promote competition. However, possible adverse consequences for infrastructure investment of mobile network operators (MNOs) create concern. In this paper,...

The objective of this research was to assess the quality of service delivered by MTN to itssubscribers. The mobile telecommunications industry in South Africa is not sufficientlycompetitive and so mobile operators can afford to ignore the quality of services theyprovide to their subscribers...

The ability to distribute and share rich media content across mobile networks representsa commercial opportunity for firms in such diverse industries as telecommunications,information technology, media and consumer electronics. Drawing on expert interviewswith industry executives, this study...

The standard model by Laffont, Rey and Tirole (1998) treats termination fees as an instrument to increase market power in a one-shot game of horizontal product differentiation. We offer an alternative view in an infinitely repeated Bertrand competition. We focus on symmetrical calling patterns...

In markets with competing interconnected networks like mobile telecommunication markets investments affect the investor's and also any competitors' profits. In a theoretical model it is shown that cost-reducing investments reduce the investor's termination rates and increase competitors'...

How does the choice to regulate a market take place? And how does regulation influence market outcome? We argue that to explicitly model the simultaneity between these two issues makes a qualitative difference in the analysis of the role of regulation, and empirically test our model in the U.S....

This paper empirically investigates contrasting views on the politics of economic policy. Merging different databases, we test various predictions coming form different strands of literature, with the aim of explaining the cross-sectional and temporal variation in the degree of regulatory...

This paper provides empirical evidence on the extent of network effects and compatibility between networks in mobile telecommunications. We specify a structural model of demand for mobile telephone service, which allows us to identify the parameters of interest from the S-shape of mobile service...

This paper empirically explores the relationship between firms’ market behavior and their lobbying activities in a regulated market. In particular, we investigate whether the amount of contributions offered by cellular service providers to fund the campaigns of political parties affected...
