Using detailed trip-level taxi and for-hire-vehicle data and new incident-level complaints data, we study how the entry of Uber and Lyft has affected the quality of taxi services in New York City. In a panel setting with 263 NYC taxi-zones over the time period from 2014 to 2017, we find that...

This paper proposes to incorporate product customization in the Maskin and Riley (1984) nonlinear pricing model in order to capture major features of mobile service data. In particular, consumers are characterized by a two-dimensional type. One dimension is observed by the provider and...

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...

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...

We estimate a dynamic oligopoly entry game in the early U.S. local telephone market. We observe the identities of potential entrants into local markets and therefore the waiting time of each potential entrant before it commits actual entry. To capture the feature of the data, we allow firms to...

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 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 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...
