This article proposes a duopoly model based on a model initially introduced by Shubik and Levitan to analyze the competition based on mobility and data volume between fixed and mobile broadband access. By the description of asymmetrical characteristics of fixed and mobile broadband offers and...

We consider a horizontally and vertically differentiated duopoly model in order to analyze both intra- and inter-platform competition in an always corvered broadband access market (Copper-Copper, Copper-FTTH and FTTH-FTTH competitions). The model is purely static and does not address dynamic...

We estimate the interaction between fixed and mobile usage both for voice and data services using consumer level data from April 2013 to March 2014 in a European country. We find a significant proportion of fixed voice consumption could be substituted by mobile voice, and vice versa. However, a...

Mobile-only users are usually considered as a consequence of fixed-mobile substitution. Via a unique dataset based on a a large European country survey and consumers' invoice data, this study reveals heterogeneous preferences for fixed services among consumers. The data is fitted in a mixed...

We estimated a mixed logit model using data on the broadband technologies chosen by 94,388 subscribers of a single European broadband operator on a monthly basis between January and December 2014. We found that consumers have similar valuation of DSL connection speeds in the range between 1 and...

Does co-investment enhance fiber to the home (FTTH) coverage, adoption and competition? We combine several French municipality-level datasets and use a two-stage control-function approach to answer this question. In the first stage, we estimate an equilibrium model of entry that predicts the...

We evaluate the impact of mobile operators merger on unitary price of data and voice by using country-level observations on data retail revenue, cellular data traffic, voice retail revenue, outgoing voice minutes. Using difference-in-differences estimation strategy, we estimate the effect of...
