Non-uniform pricing equilibria are shown to dominate uniform pricing equilibria in free entry, monopolistically competitive markets with identical consumers. The non- uniform pricing equilibrium is welfare optimal. Comparisons of Cournot and non-uniform pricing equilibria in terms of the...

We show that, despite coordination in the quality level of the components that they provide, independent vertically-related (disintegrated) monopolists will provide products of lower quality level than a sole integrated monopolist. Further, the integrated monopolist achieves higher market...

We discuss the effects of strategic commitments and of network size in the process of setting interconnection fees across competing networks. We also discuss the importance of the principles of reciprocity and imputation of interconnection charges on market equilibria. Reciprocity means that...
