In this paper we use panel data on NUTS 1 regional data for 27 EU countries in the years 2006-2010 to analyze determinants of broadband diffusion. We estimate both linear demand specification and the logistic diffusion function. We find that, after controlling for regional differences due to socioeconomic factors, inter-platform competition approximated by an inter-platform Herfindahl index has a significant positive impact on broadband diffusion.
This paper analyzes substitution between access to fixed-line and mobile telephony in the European Union. We estimate a structural model of household's demand for: (i) fixed-line only; (ii) mobile only; (iii) and both fixed-line and mobile access. We find that decreasing prices for mobile services increase the share of 'mobile only' households and decrease shares of 'fixed only' and 'fixed + mobile' households which suggests substitution between fixed-line and mobile connections.
Is the quality of interconnection between Internet operators affected by their asymmetry? While recent game theoretic literature provides contrasting answers to this question, there is a lack of empirical research. We introduce a novel dataset based on Internet routing policies, and study the interconnection decisions amongst the Internet Service Providers (ISPs) members of the London Internet Exchange Point (LINX). Our results show that interconnection quality degradation can be significantly explained by asymmetry between providers.
