Book Description
This paper analyzes the impact of network externalities on Ramp;D competition between an incumbent and a potential entrant. The analysis shows that the incumbent always invests more than the entrant in the development of higher quality network goods. However, the incumbent exhibits a too low level of investments, while the entrant invests too much in Ramp;D in comparison with the social optimum. In the model entry occurs too often in equilibrium. These inefficiencies are solely due to the presence of network externalities. By choosing compatible network goods, firms do not necessarily reduce the Ramp;D competition intensity.

Book Description
Positive network externalities can arise when consumers benefit from the consumption of compatible products by other consumers (user-positive consumption externalities) or, alternatively, when they incur costs from the consumption of incompatible products by other consumers (nonuser-negative consumption externalities). But whereas user-positive externalities are typically mutually imposed and imply mutual benefit because they relate to interoperability, with nonuser-negative externalities the costs of incompatibility may be imposed unilaterally and borne asymmetrically. For example, increased risks of death and injury on the roads due to the co-existence of large and small vehicles are imposed exclusively by the owners of the large vehicles and borne exclusively by the occupants of the small vehicles. This paper compares the social optimality of incentives for compatibility under regimes involving user-positive and nonuser-negative externalities. Earlier work with respect to user-positive externalities (e.g., Katz and Shapiro, 1985) suggests that firms with relatively small networks or weak reputations tend to be biased in favor of compatibility, while individual firms' incentives for compatibility are suboptimal when their networks are closely matched in size. Meanwhile, intuition suggests that with nonuser-negative externalities incentives for incompatibility should always be excessive, reflecting the notion that activities involving unilaterally imposed negative externalities will always be overprovided by the market (in the absence of regulation or Coaseian mitigation). Using a "location" model of differentiated products, we find that, under both regimes, incentives for compatibility tend to be suboptimal when firms' networks are close in size, and excessive for the small firm when the networks differ greatly in size. Surprising public policy implications with respect to externalities are discussed.

Book Description
This paper analyzes the economics of industries where network externalities are significant. In such industries, firms have strong incentives to adhere to common technical compatibility standards so that they reap the network externalities of the whole group. However, a firm also benefits from producing an incompatible product thereby increasing its horizontal product differentiation. We show how competition balances these opposing incentives. We find that market equilibria often exhibit extreme disparities in sales, output prices, and profits across firms, despite no inherent differences in the firms' production technologies. This may explain the frequent domination of network industries by one or two firms. We also find that the presence of network externalities dramatically affects conventional welfare analysis, as total surplus in markets where these externalities are strong is highest under monopoly and declines with entry of additional firms.

Book Description
Are all film stars linked to Kevin Bacon? Why do the stock markets rise and fall sharply on the strength of a vague rumour? How does gossip spread so quickly? Are we all related through six degrees of separation? There is a growing awareness of the complex networks that pervade modern society. We see them in the rapid growth of the internet, the ease of global communication, the swift spread of news and information, and in the way epidemics and financial crises develop with startling speed and intensity. This introductory book on the new science of networks takes an interdisciplinary approach, using economics, sociology, computing, information science and applied mathematics to address fundamental questions about the links that connect us, and the ways that our decisions can have consequences for others.

Book Description
'Due to their economic characteristics and also to their consequences on many aspects of collective life, information networks have always been at the edge of regulatory innovations and at the center of policy debates. The contributors of this volume combine long term visions of the factors determining regulatory policies with up-to-date analyses of technicalities to be dealt with, to provide the reader with an extended understanding of the issues and constraints shaping the future of digital networks.' Eric Brousseau, Université Paris-Dauphine, France and the European University Institute, Italy Digital markets worldwide are in rapid flux. The Internet and World Wide Web have traditionally evolved in a largely deregulated environment, but recently governments have shown great interest in this rapidly developing sector and are imposing regulations for a variety of reasons that are changing the shape of these industries. This book explores why the industrial organization of broadband ISPs, Internet backbone providers and content/application providers are in such turmoil. The expert contributors straddle the turbulent past of the telecoms sector and also contribute to its exciting though unpredictable future via positive analysis of past communications policies, which is then utilized to deduce lessons to guide future policy making decisions. It is illustrated that broadband ISPs no longer simply provide a conduit for service delivery; they are also involved in producing content and transaction services themselves, in competition with content and delivery providers. The blurring of the traditional lines between these three sectors, as each enters into the others' markets, is highlighted. The conclusion is that we are witnessing the emergence of powerful, competing platforms, linked in complex ways that challenge traditional economic analyses. Exploring governance issues, regulation and investment, next-generation service markets and wireless communication, this book will prove a fascinating and illuminating read for scholars, researchers, post-graduate students and policymakers with an interest in ICT, technology and innovation, economics and industrial organization.
