Resumo(s)
NGAs (Next Generation Access Networks) are a challenge to regulators and operators
insofar as they require large investments, there is significant uncertainty about the ability to
recover costs, and the choice of the appropriate regulatory regime is far from consensual.
Regulatory authorities might want to seize the moment and reconsider the mandatory vertical
separation of telecommunication firms, without jeopardizing incentives to innovation,
investment and welfare.
We provide a provocative but simple test for the adequacy of network separation as a
regulatory remedy. We propose a decision tree procedure with four steps in order to assess
whether network separation is an adequate regulatory response: [1] “Is there significant market
power in the market for the provision of access services under NGAs?”; [2] “Are there few
vertical complementarities between services along the supply chain?”; [3] “Is functional
separation a better regulatory tool than any other alternative?”; and [4] “Is structural separation
superior to functional separation?”. A positive answer to the first three questions implies that
the regulator should consider functional network separation, whilst the fourth is needed for the
structural alternative.
