The "ladder of investment" is a regulatory approach proposed by Martin Cave (2006), which has been widely embraced by national regulatory authorities in the European telecommunications sector. The approach entails providing entrants, successively, with different levels of access - the "rungs" of...

The model of liberalisation of European telecommunications markets had followed what has become known as the "ladder of investment" (LoI) hypothesis: under this hypothesis entrants are expected to make progressively greater investments in their own networks, whilst decreasing their dependence on...

We study the impact of the access charges of copper and fiber unbundling on an incumbent's incentives to invest in fiber access networks. Once the fiber deployment is in place, the incumbent and the entrant compete for consumers in both copper and fiber markets. We show that when the regulator...

How can innovation and competition be sustained in closed tight oligopolistic market structures? This question will be crucial in the next years for an appropriate regulation of mobile markets. The regulatory framework era of the postulate of infrastructure based competition seems behind us. It...

Governments around the world recognise widespread broadband access as a facilitator of economic growth. As a result we observe that many countries have introduced National Broadband Policies which set ambitious targets for broadband coverage. Fixed network may not be commercially viable in more...

States and their representatives, national governments, play a key role in national telecommunication markets. As lawmakers, they determine the playing field of the agents in the markets and the decision powers of national regulators. Simultaneously, they are involved in appointing presidential...

In 2000, there were as many countries served by a single mobile network as by network competition. Today, only 30 countries, representing less than 3% of the world’s population, are served by a single network. There has been considerable discussion about the optimal number of network operators...

Regulatory authorities, governing markets and industries around the world, aim to develop a fair and equivalent competitive market with low entry and exit barriers that provide customers with sufficient knowledge and information to enable them to switch between products, services and suppliers...
