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...

We analyze the salient features of networks and point out the similarities between the economic structure of networks and the structure of vertically related industries. The analysis focuses on positive consumption and production externalities, commonly called network externalities. We discuss...

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...

Liquidity plays a crucial role in financial exchange markets. Markets typically create liquidity through spatial consolidation with specialist/market makers matching orders arriving at different times. However, continuous trading systems have an inherent weakness in the potential for...

A model of franchising competition in locationally differentiated products is constructed. A franchisor (upstream firm) collects a marginal transfer fee per unit of output sold by a franchisee (downstream firm). For example, the marginal transfer fee can be realized as a markup on variable...

The structure of the telecommunications industry has changed substantially in the last decade,raising public concern that the quality of our information infrastructure may be adversely affected. This paper extends the standard vertical differentiation model of imperfect competition to address...
