In this paper we study how the coexistence of access regulations for legacy (copper)and fiber networks shapes the incentives to invest in network infrastructure. To this end, we develop a theoretical model explaining investment incentives by incumbent telecom operators and heterogeneous entrants...

Unbundling has been made to work in a number of countries with relatively dense and well developed traditional copper networks. However, the conditions have been exacting, requiring: customisation for the national market, alternative operators willing to enter the market, medium‐term legal...
