My curiosity with the economic efficiency and social benefits of provisions used by telecommunications carriers to limit their liability to customers for damages arising from service interruptions and network outages is a longstanding one. It began with the changing state regulatory environments in the late 1980's while representing AT&T as an attorney before numerous state legislatures in the Midwest. As telecommunications carriers faced the ramifications of deregulation, several legal consequences came to the fore. One important consequence was the impact of changing regulatory rules and requirements on the carriers' abilities to continue to limit their liability for damages to customers in a non-tariffed world. As a result, one of my responsibilities while employed by AT&T was to syek legislative relief in some state jurisdictions which would enable the continued use of limited liability provisions notwithstanding other deregulatory developments in the industry. In my capacity as an attorney, I succeeded in this task in the few jurisdictions for which I was given the charge. However, as an economist, these efforts piqued my interest regarding the economic effects of such limited liability provisions on consumer interests. What liability rules for the industry would really better serve general societal interests? As my career evolved, which involved returning to graduate school to pursue my Ph. D. and becoming the Director of Public Policy Studies at Ameritech, I had the opportunity to pursue interdisciplinary research in telecommunications policy issues.

'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.

Randall B, Lowe Piper & Marbury, L.L.R The issue of costing and pricing in the telecommunications industry has been hotly debated for the last twenty years. Indeed, we are still wrestling today over the cost of the local exchange for access by interexchange and competitive local ex change carriers, as well as for universal service funding. The U.S. telecommunications world was a simple one before the emergence of competition, comprising only AT&T and independent local exchange carriers. Costs were allocated between intrastate and interstate jurisdictions and then again, between intrastate local and toll. The Bell System then divided those costs among itself (using a process referred to as the division of revenues) and independents (using a process called settlements). Tolls subsidized local calls to keep the politi cians happy, and the firm, as a whole, covered its costs and made a fair return. State regulators, however, lacked the wherewithal to audit this process. Their con cerns centered generally on whether local rates, irrespective of costs, were at a po litically acceptable level. Although federal regulators were better able to determine the reasonableness of the process and the resulting costs, they adopted an approach of "continuous surveillance" where, like the state regulator, the appearance of rea sonableness was what mattered. With the advent of competition, this historical costing predicate had to change. The Bell System, as well as the independents, were suddenly held accountable.

The Telecommunications Act of 1996 envisioned a competitive free-for-all in the U.S. telecommunications industry with removal of barriers to entry in local telecommunications markets and the lifting of the artificial restrictions that kept the Regional Bell Operating Companies (RBOCs) out of the interLATA long-distance market. After close to 5 years, only one RBOC has been granted permission (controversially) to enter the interLATA market, and local competition has yet to provide most consumers with meaningful choices. In addition, the wave of mergers across the industry has raised the specter of putting the former Bell System back together again. Policymakers now openly question whether the Act can deliver what it promised. Three principal themes are developed in this book. First, there has been a coordination failure between Congress and the FCC in translating the principles embodied in the Act into practice. The authors provide evidence for this by analyzing stock market reactions to legislative and regulatory actions. This coordination failure was largely predictable, given the ambiguity in the Act, as well as conflicting jurisdictions between the FCC and the states. Second, the Act calls for wholesale prices to be `based on cost.' Regulators adopted a costing standard (TELRIC) that provides a means to subsidize competitive entry in local telephone service markets. The ready adoption of the TELRIC standard by regulators is shown to be tied to the third theme: price cap regulation provides regulators with `insurance' against the adverse effects of competition in local telephone markets. Statistical analysis reveals that regulators in price cap states set uniformly lower unbundled network element prices (lower barriers to entry) in comparison with regulators in rate-of-return and earnings sharing states. The result is a triumph of regulatory processes over market processes - the antithesis of the purpose of the Act.

The aim of this book, Future of the Telecommunications Industry: Forecasting and Demand Analysis, is to describe leading research in the area of empirical telecommunications demand analysis and forecasting in the light of tremendous market and regulatory changes. Its purpose is to educate the reader about how traditional analytic techniques can be used to assess new telecommunications products and how new analytic techniques can better address existing products. The research presented focuses on new products such as Internet access and additional lines and new techniques such as hazard modeling, adaptive forecasting and neural networks. The scope of this volume includes new telecommunications products, new analytical techniques, and a review of market changes in the US and other countries. Some of the most critical questions facing the industry are addressed here, such as the impact of competition, customer churn, rate re-balancing, and early assessment of new products. The research includes a variety of different countries, products and analytic tools.
