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....

Network performance measurements from OECD countries between 2007 and 2012 document a significant increase in the variability of broadband infrastructure quality, which helps explain growing demand for technologies and policies that counteract information asymmetries between network operators...
