Abstract: We consider the impact of a regulatory process forcing an incumbent telecom
operator to make its local broadband network available to other companies
(local loop unbundling, or LLU). Entrants are then able to upgrade their
individual lines and offer Internet services directly to customers. Employing a
very detailed dataset covering the whole of the UK, we find that over the
course of time, many entrants have begun to take advantage of LLU.
However, unbundling has little or no effect on broadband penetration,
compared to those areas where the loops are not unbundled. LLU entry
instead has a strongly positive impact on the quality of the service provided.
We also assess the impact of competition from an alternative form of
technology (cable) which is not subject to regulation, and what we discover is
that inter-platform competition has a positive impact on both penetration and
