Abstract:
Fibre-deployment of next-generation communications networks is currently a major challenge
for investing firms as well as for national regulators and is also subject to hot debates at EU
level. This work examines the role of regulatory policies and competition controlling for relevant
supply and demand side factors. Our econometric model employs dynamic panel data methods
that take into account potential endogeneity due to omitted heterogeneity, reverse causality
and the dynamic investment specification.
Our results indicate that relevant forms of previous broadband access regulations have
had a negative impact on investment in new infrastructure. Furthermore, infrastructure-based
competition from mobile operators and the replacement effect stemming from the incumbents’
existing infrastructure exert a negative impact on ex ante investment incentives. As regards the
dynamics of the adjustment process, we find that there are both short-term and long-term
effects towards the desired infrastructure level.
