I study how firms actually compete in nonlinear tariffs by analyzing whether the incumbent and entrant's decisions to offer a given number of tariff options are interrelated. The goal is to shed some light on those dynamic and strategic aspects of tariff menus that are currently ignored by...

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...

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 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...

We analyze firms' incentives to bundle and tie in the telecommunications industry. As a first step, we develop a discrete-choice demand model where firms sell products that may combine several services in bundles, and consumers choose assortments of different types of products available from...

We provide a theory that unifies the long tail and blockbuster phenomena. Specifically, we analyze a three-stage game where, first, a large number of potential firms make entry decisions, then those who stay in the market decide on the investment in its product, and lastly customers with...

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...

We use rich survey data on 133,825 households from 27 EU countries during 2005-2011 to analyze substitution between fixed-line and mobile telecommunications services. We estimate a discrete choice model where households may choose between having mobile or fixed-line voice access only, or using...

This paper studies the efficient use of prioritization in Amazon's Twitch.tv, taking into account the trade-off between entry and congestion. I specify and estimate supply and demand models for live video, and a congestion model. Using technological shocks, I identify congestion costs for...

Government infrastructure investment in mixed markets may crowd out investment from private firms, or it may induce them to invest preemptively. The tension between these effects underlies the policy debate over whether to allow municipal provision of internet access. The goal of this paper is...
