Incompatibility across rival systems can influence incentives to invest in product changes beneficial to the consumer. We investigate this phenomenon in the case of bank ATM networks, where the number of ATM locations is a measure of product quality and surcharge fees serve as an index of...

We study the diffusion of competing two-sided networks using a differential game framework. We find that whether the winner takes all depends on the participation behaviour of individual agents on both sides of the market. When individual agents tend to participate in only one network, one...

Trade-offs between imitation and innovation create natural tensions in the design of competition policy for the telecommunications industry. We explore the relationship between the prices of unbundled network elements (UNEs) and static/dynamic efficiency. We find that even when UNEs are priced...

This paper traces the history of TEX, the open source typesetting program. TEX was an early and very successful open source project that imposed its standards in a particularly competitive environment and inspired many advances in the typesetting industry. Developed over three decades, TEX came...

The goal of SEPA (Single Euro Payments Area) is to facilitate the emergence of a competitive, intra-European market by making cross-border payments as easy as domestic transactions. With cross-border inter-operability for electronic payments, card transactions will increasingly replace cash and...

In this paper, we survey the literature on optimal pricing of a monopolist operating on a network industry. We also describe explicitly the optimal path of prices for a monopolist facing an expanding demand due to the presence of network effects. The optimal path of prices appears as a function...

This paper analyzes telecommunications demand by firms, focusing on communication flows among production units. We consider first the case of two business unit that can play simultaneously or in a leader/follower situation regarding their communication decisions. In this context, we define the...
