The debate on the regulation of Next General Access started in Europe several years ago. It addresses the question of whether or not fibre access networks should be subject to the same regulation as the copper local loop. This debate is often examined as competition vs. investment. The present...

We analyze the incentives of a telecommunications incumbent to invest and give access to a downstream entrant to a next generation network. We model the industry as a duopoly, where a vertically integrated incumbent and a downstream entrant, that requires access to the incumbent's network,...

Recently, investments in new generation networks in Germany have been curtailed, since potential investors required this new network be unregulated. To develop a regulator's strategy that allows investments to occur but prevents monopolistic prices, we model an investor's decision problem under...

We analyze if two-part access tariffs solve the dynamic consistency problem of the regulation of Next Generation Networks. We model the industry as a duopoly, where a vertically integrated incumbent and a downstream entrant, that requires access to the incumbent's network, compete on Hotelling's...

We analyze the incentives of a telecommunications incumbent to invest and give access to a downstream entrant to a next generation network, NGN. We model the industry as a duopoly, where a vertically integrated incumbent and a downstream entrant, that requires access to the incumbent's network,...

We consider a two-sided market model with a monopolistic Internet Service Provider (ISP), network congestion sensitive content providers (CPs), and Internet customers in order to study the impact of Quality-of-Service (QoS) tiering on service innovation, broadband investments, and welfare in...

Since the 1980s, developing countries started adopting telecom reforms due to pressures from international institutions. However, Middle East and North African (MENA) countries lagged in adopting such reforms. Even after introducing telecom reforms in the MENA region beginning in 1995, not all...

For many years electronic communications has been one of the most important areas of policy intervention for the European Union. Liberalisation and privatisation of the telecommunications industry have been very important topics of the policy debate in the two decades starting from 1990 to 2010....

This paper deals with the relationship between the traditional fixed-line, mobile and Voice over IP telephony in the EU.We estimate the supply and demand for fixed-line telephony using data on 25 EU member states for the 2006:Q2 - 2011:Q4 period. Employing instrumental variable approach, we...

This paper analyzes the relationship between the traditional fixed-line, mobile and Voice over IP (VoIP) telephony in the EU. In doing so, it aims at filling the gap in the empirical literature on the substitution patterns between these technologies in a comprehensive way. It relies on demand...
