We analyze the incentives of a telecommunications incumbent to invest and give access to a downstream entrant to a next generation network, NGN. We model the industry as a duopoly, where a vertically integrated incumbent and a downstream entrant, that requires access to the incumbent's network,...

There is a substantial number of cases where the a priori relationship between products is not at all clear in the sense that although apparent to be clear substitutes may turn out to be in fact complements, or vice-versa. This paper aims to study the relationship between fixed and mobile...

We study a retail benchmarking approach to determine access prices for interconnected networks. Instead of considering fixed access charges as in the existing literature, we study access pricing rules that determine the access price that network i pays to network j as a linear function of the...

We study how access pricing affects network competition when consumers' subscription demand is elastic and networks compete with non-linear prices and can use termination-based price discrimination. In the case of annexed per minute termination charge, our model generalizes the results of Gans...

We analyse competition between perfectly substitutable networks. Monopolization can be sustained in equilibrium by asymmetric access prices whereby entry is deterred by a set of margin squeezes. A regulatory package consisting of (i) mandatory interconnection; (ii) reciprocal access prices;...

We consider some two dynamic models of entry in mobile telephony, with and without strategic pricing, and taking into account market penetration at entry, locked-in consumers and tariff-mediated network externalities. We show that on/off-net differentials may reduce the possibility of entry if...

This paper questions whether competition can replace sector-specific regulation of mobile telecommunications. We show that the monopolistic outcome may prevail independently of market concentration when access prices are determined in bilateral negotiations. A lighthanded regulatory policy can...

I generalize the workhorse model of network competition (Armstrong, 1998; Laffont, Rey and Tirole, 1998a,b) to include income effects in call demand. Income effects imply that call demand depends also on the subscription fee, not only on the call price. In the standard case of differentiated...

We analyze how termination charges a ect retail prices when taking into account that receivers derive some utility from a call and when rms may charge consumers for receiving calls. A novel feature of our paper is that we consider passive self-ful lling expectations and do not allow for negative...

This paper evaluates whether competition hinders or spurs investment in a network industry. When a network is split between competitors, potential network effects are foregone. However, a firm may invest in components that are not shared, to steal customers from its competitors. I structurally...
