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

We examine the effects of mobile termination rate regulation in asymmetric oligopolies. We do this by extending existing models of asymmetric duopoly and symmetric oligopoly where consumer expectations about market shares are passive. We first calibrate product differentiation parameters using...

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

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 a fixed per minute termination charge, our model generalizes the results of Gans...

In this article I analyze the effects of a recent reform intended to decrease switching costs in the cellular industry. The reform, implemented in Chile in 2012, allowed cell phone users to switch operators without any contract restriction while keeping their wireless number. Its aim was the...

I discuss the design and implementation of a SSNIP test in order to identify the relevant market in a media market. I argue that in such a two-sided market the traditional SSNIP test cannot be applied as it is usually conceived but rather should be modified in order to take into account indirect...

Local telecommunications competition was an important goal of the 1996 Telecommunications Act. We evaluate the consumer welfare effects of entry into residential local telephone service in New York State using household-level data from September 1999 to March 2003. We address the prevalence of...

In this paper, we evaluate the consumer welfare effects of entry into residential local phone service in New York State. Residential local phone service competition was an important goal of the 1996 Telecommunications Act. We provide a detailed evaluation of its effects on consumer welfare using...

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...
