This paper assesses the private and social incentives for disjoint networks to interconnect under various ownership structures. Terms of interconnection are derived for a noncooperative equilibrium. We find that networks mutually profit from interconnection when it creates new services that did...

This paper shows how fixed costs can play an important role in determining the structure of organizations. Applications considered include layoffs, downsizing, heterogeneity among firms, and the structure of hierarchies. Agency problems as a source of fixed costs are also considered.

By a well-known argument, securities holders do not directly benefit from risk-reducing corporate diversification when they can replicate this difersification on their own. Some have argued that corporate diversification may be of value, or can otherwise be explained by, the agency relationship...

We discuss the case of a monopolist of a base good in the presence of complementary goods provided either by it or by other firms. We assess and calibrate the extent of the influence on the profits from the base good that is created by the existence of complementary goods, i.e., the extent of...

This paper evaluates the effectiveness of several pricing rules intended to promote entry into a network industry dominated by an incumbent carrier. Drawing on the work of Cournot and Hotelling, we develop a model of competition between two interconnected networks. In a symmetric equilibrium,...

We extend the results of our article, "Access and Interconnection Pricing? How Efficient Is the "Efficient Component Pricing Rule?," Antitrust Bulletin (1995). In the presence of a monopolized essential input, we show that application of the Efficient Component Pricing Rule ("ECPR") in pricing...

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...

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...

This paper critiques some of the properties of the so-called "efficient component pricing rule" (ECPR) for access to a bottleneck (monopoly) facility. When an entrant/rival and the bottleneck monopolist both produce a complementary component to the bottleneck service, the ECPR specifies that the...

We discuss the incentive of an exclusive holder of a technology to share it with competitors in a market with network externalities. We assume that high expected sales increase the willingness to pay for the good. This is named the "network effect". At a stable fulfilled expectations...
