We investigate the impact of backward compatibility on the adoption of multi-generation platforms. Our context is a mobile platform where platform users download services from third party providers. For each hardware platform generations, the services depend greatly on the embedded...

Over the past five years, the use of mobile and wireless technology in public spaces of cities around the country has grown exponentially. There has been little analysis of the ways in which the use of the wireless Internet via WiFi may differ from that of the wireline Internet. This paper...

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...

Since 2008, multiple smartphone platforms have launched versions of “app stores”, marketplaces where consumers can purchase and download software applications for their smartphone. This paper provides evidence for both demand and supply of “apps” using data on the size and composition of...

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 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...

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...

Signal quality is a significant contributor to the overall quality of wireless telephone service, which competitive analyses often overlooks. To understand the competitive impact of signal quality investment on further consolidation in this industry, I use a market research survey of choice 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...

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...
