We consider a two-sided market model with a monopolistic Internet Service Provider (ISP), network congestion sensitive content providers (CPs), and Internet customers in order to study the impact of Quality-of-Service (QoS) tiering on service innovation, broadband investments, and welfare in...

We study how access pricing affects network competition when consumers' subscription demand is elastic and networks compete with non-linear prices and can use termination-based price discrimination. In the case of a fixed per minute termination charge, our model generalizes the results of Gans...
