Non-cost-raising discrimination: A rationale for functional separation in broadband open access

Registered author(s):

    I present a vertical differentiation model to assess the quality-wise strategy of an incumbent telecommunications operator under open access regimes. I show that it is always profitable for an incumbent subject to wholesale regulation to degrade wholesale quality in a non-recoverable fashion. The findings are robust to the number of competitors and the price cap level, unlike those predicted by the cost-raising discrimination paradigm. I also show that functional separation, a structural remedy aimed at separating the incumbent's wholesale and retail operations, better aligns supply-side incentives with those of consumers. The analysis suggests that structural remedies exhibit good properties to implement open access regimes.
