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...

Broadband internet expansion is a topic of widespread discussion in Germany right now. But the country still has not met its own targets. Almost 100 percent of households are supplied with broadband connections with up to six megabits per second, yet Germany has lots of room to catch up when it...

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...

We develop a model of competition between interconnected networks, with separate local and long-distance markets, allowing for various degrees of symmetry between carriers. Assuming two part pricing, we show that effective competition can be achieved with simple regulations involving mandatory...

This Article offers an all new solution to the problem of interconnection between telecommunication networks. The FCC recently proposed to take regulation of interconnection to the most extreme degree of intervention. According to this proposal, interconnection between LECs and other carriers...
