Abstract 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...

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 call-ing patterns...

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 argues that the study of policy incidence in industrial organization needs to take the endogeneity of government into account. The point is made by investigating whether political considerations are important in terms of understanding the causes and effects of deregulation using data...

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 develops a political-economy model of price regulation. Firms' lobbying activity for a given regulatory status might generate a simultaneity problem between the effects and the determinants of regulatory decisions. We explicitly model this two way causality, and empirically test our...

We study the determinants of the diffusion of mobile telecommunications services in the European Union in a logistic model of technology diffusion. We find that the transition from the analogue to the digital technology during the early nineties, and the corresponding increase in spectrum...

A few recent contributions have claimed that in high-tech industries—where innovation is often cumulative and products include many components which are protected by patents in the hands of many different patent holders—the cost of obtaining all necessary licenses is too high. Some have even...

We analyze the effect of government policies on the evolution of global mobile telecommunications markets during 1981-1997. We obtain the following findings. (i) Countries that issue first licenses at later dates converge relatively slowly to early moving countries. (ii) The introduction of...

This paper gives a model for price competition under consumer switching costs in a network setting with interconnection charges. This simultaneous analysis is conducted in a discrete choice model with a multinomial logit differentiation for the customers and not in a traditional Hotelling...
