What is the magnitude of fixed–mobile call substitution? Empirical evidence from 16 European countries

This paper investigates the degree of fixed–mobile call substitution (FMCS) within different European countries. We use quarterly data from 2004 to mid-2010 on 16 mainly Western European countries. By applying dynamic panel data techniques, we are able to estimate short- and long-run elasticities of the telecommunication usage prices on the fixed-line call demand. The own-price and cross-price elasticities found give strong empirical evidence for substitutional effects towards mobile services. In particular, the estimated cross-price elasticities of the mobile price on the fixed-line call demand are relatively large compared to other studies.     

Detecting the relationship between competitive intensity and firm product line length: Evidence from the worldwide mobile phone industry

The way firms lengthen or shorten their product line with respect to rivals is regarded as one of the possible strategies firms can pursue to respond to competition. This article builds and tests hypotheses to study the effect of different levels of competitive intensity on product line length. The empirical analysis of data on 3,527 handset models introduced by 66 mobile phone vendors from 1994 to 2010 shows a consistent inverse U‐shaped relationship between competitive intensity and the firm's product line length. In this way, we pinpoint an interesting link between the product line extension literature and the competitive dynamics and competitive intensity perspectives.

TRAFFIC MANAGEMENT IN WHOLESALE INTERNATIONAL ROAMING: TOWARDS A MORE EFFICIENT MARKET?*

Despite a general trend of lower charges for mobile calls, in Europe, prices for international roaming calls have remained at levels that are surprisingly high. The apparent reluctance of mobile network operators to lower roaming tariff is generating many antitrust concerns. This paper presents in a two‐country two‐firm framework the functioning of the current system governing wholesale international roaming agreements based on interoperator tariffs. The focus is on the role of traffic management; thanks to the emergence of traffic direction techniques, mobile network operators are allowed to select the roaming partner. We show that, unless these techniques do not allow for perfect control on traffic flows, traffic management does not improve the market's efficiency. In line with the regulatory mechanism recently adopted by the European Commission, we show that a simple price cap mechanism may restore partial efficiency in the wholesale market. We also show that although cross‐border cooperation at the wholesale level is Pareto efficient, it will not emerge as an equilibrium of a two‐sided matching game.

An Exploratory Study of Convention Specific Social Media Usage by Attendees: Motivations and Effect of Generations on Choice of Convention Information Source and Intention to Use Mobile Application

While social media and mobile devices have grown as important tools of communication and marketing in the meeting industry, limited research has explored convention attendees’ perception of convention specific social networking media and what the motivations are for attendees’ adoption of using convention specific social media. This study aims to identify convention attendees’ motivations of using convention specific social media and demands of convention specific mobile applications. This study also investigated how attendees’ generation affects their selection of convention information sources and attitude toward mobile applications. Based on the identified key motivations of using convention specific social media, convention organizers need to build social media that provide up-to-dated convention information as well as a functionality of building community among attendees. The findings also show that generation affects the choice of convention information source and intention of mobile applications usage. This study identified the most demanded convention mobile applications including, exhibitor directory search, convention floor plan, and convention itinerary planner. This study can be used as a basis for more extensive examinations of the use of social media in conventions and for empirical testing of convention attendees’ attitudes toward convention social media and mobile applications.
