This paper reexamines broadly. from the standpoint of innovation, the arguments for vertical integration in the U.S. telecommunications industry in light of structural change since the breakup of the Bell System. While basic and applied research became the casualty of the 1984 breakup and the 1995 AT&T split, there is no evidence that the pace of innovative activity and productivity has slowed. Evidence from R&D and patent data suggests some acceleration of innovative activity. However. the service segment of the industry ceased to be the center of technological innovation. The source of future innovation seems to lie in the telecommunications and Internet equipment firms and independent software firms. The emergence of the competitive stand-alone software industry, combined with a trend towards open operating systems and customer demand for greater flexibility, and growing substitution of technology alliances for in-house R&D appear to have undermined the case for vertical integration in the telecommunications industry. From the standpoint of business strategy, the question of whether a firm like AT&T, notwithstanding its huge investments in cable facilities, can develop distinctive and sustainable capabilities through horizontal expansion and ubiquity and one-stopshopping marketing alone remains open.  相似文献

The pro- and anti-competitive implications of technical compatibility standards are introduced in general terms and then applied to current issues in telecommunications policy. The demand and supply for standards under regulated monopoly and the transition to deregulation and competitive entry create a tradeoff between the traditional goal of achieving positive externalities from interconnection and the alternative goal of providing enhanced service offerings that may involve sacrificing universal connectivity. We argue that this tradeoff has affected the utilization of data communication networks in the U.S. and Europe. In addition, we identify problems of competing interests that complicate the European approach to standards “harmonization” in the case of telecommunications. We conclude by noting that the nature of standards and standard-setting process can have marked effects on the incentives to conduct private research and development.  相似文献

The article points out the often neglected political importance of telecommunications planning experts. It does so by first locating policy planning in the larger socletal phenomenon of technocracy. Next discussed is the relationship of policy planners to political power. Finally the article examines some instances of national telecommunications planning, in particular the USA.  相似文献

A primary goal of the 1996 Telecommunications Act isto encourage competition in long-distance telephonemarkets. Four years after passage of thislegislation, Bell Operating Companies (``BOCs') havebeen granted permission to offer long-distanceservices in only one state. The regulatory barrier toentry is justified on grounds that the BOCs have theability to discriminate against incumbentlong-distance carriers in the provision of essentialaccess services. We take this premise as given andquantify the critical level of discrimination requiredto offset the positive consumers' surplus gainsassociated with the enhanced competition resultingfrom BOC entry into long-distance markets.  相似文献

Reflecting on his involvement with Telecommunications Policy, since 1979, this article by one of its first editors Colin Blackman, contributes to the 40th anniversary issue. It describes the launch of the journal, the unique nature of its publisher, IPC Science & Technology Press, the way in which the field has changed over the past four decades, and makes some personal observations about the changing nature of the world of journal publishing.  相似文献

The past nearly 40 years have seen major developments in telecommunications networks and services, and in how they are regulated. This paper describes innovations in UK telecommunications regulation which have taken place over the period, broken down into stages, beginning with the regulation of the former monopolist by an independent regulator under a price cap, continuing the regulation first of mobile and then, under European Directives, of copper-based broadband, and ending with the diffusion of fibre networks. It is argued that a variety of changes have reduced the scope of innovation over the period, including domestic institutional reform, the limits placed on later decisions by earlier ones (path dependency), and the constraining impact of European Union law and regulation. The paper concludes with some consideration of the effects on future innovation of the UK’s withdrawal from the EU.  相似文献

Financial crises are still as much a part of the modern, information-and-communication-technology-based (ICT) economy as they were of previous economies. Why are we apparently unable to learn lessons from the past and avoid what Charles Kindleberger (2000) has called manias, panics and crashes? Why is it that our sophisticated stock of information, made readily and relatively cheaply available to us by our investment in ICTs, and our abundant theories and models, have not allowed us to steer clear of these financial excesses? The aim of this paper is to highlight some of the processes and mechanisms that have played a significant role in causing the Telecoms Boom and Bust, 1996-2003. The question of whether anything can be done about these processes and mechanisms in order to try and modify such financial excesses in the future is taken up in the conclusion.JEL Classification: A12, D8, E3, G1, L63, L96, N2, O30The author would like to acknowledge, without implicating, the helpful discussion with Richard Burns, Fred Bleakley and others who commented on an earlier version of this paper at Institutional Investors European Institute meeting in Berlin in March 2003, and with Stan Metcalfe on other occasions. In addition, thanks are due to many friends in NTT and InfoCom who assisted my learning about the Telecoms Industry and its dynamics.  相似文献

The author examines the impact of competition from both domestic and international perspectives. He provides a critique of the pro-competition argument, although a number of advantages of competition are also outlined. The advantages are discussed in relation to equipment and services. International trends towards competition are then described and the disadvantages of such trends are debated in relation to cross-subsidization, interconnection, the telecommunications manufacturing industry, and the market structure. Finally, competition in the international arena is discussed.  相似文献

Since the enactment of the Telecommunications Act of 1996 (1996), extensive expert testimony has justified use of the ‘modified’ t statistic (Brownie et al. Biometrics 46 (1990) 259–266) for performing two-sample hypothesis tests on Bell companies’ CLEC and ILEC performance measurement data. This paper demonstrates how key statistical claims made about the ‘modified’ t in this setting are false, leading not only to incorrect inferences as it currently is being used, but also to the possible undermining of the primary stated objective of the Act—the promotion of competition in the newly deregulated local telephone service markets. A simulation study provides strong evidence for the use of several other easily-implemented statistical procedures in this context; they should be useful in other settings as well.  相似文献

This study uses a two-stage approach to explore the relationship between the operational performance of U.S. telecommunications companies and their implementation of corporate social responsibility (CSR). In the first stage, this study adopts the dynamic data envelopment analysis model to measure the efficiency of the telecommunications industry in the U.S. from 2004 to 2008. The empirical results show that the corporate efficiency of those companies that implemented CSR was higher than that of those companies that did not. In the second stage, the study adopts OLS and 2SLS to explore the influence of the execution level of CSR on performance. The results show that the Kinder, Lyndenberg, and Domini & Co (KLD) social ratings indexes are significantly and positively related to corporate performance. Finally, this study suggests ways in which corporate policy makers can enhance CSR in order to improve corporate performance in the U.S. telecommunications industry.  相似文献
