Communications policy and information technology promises, problems, prospects by Communication, and Internet Policy Research Conference on Information( file )
8 editions published in 2002 in English and held by 1,141 libraries worldwide
This volume examines the complex ways in which communication technologies and policies affect the people whose lives they are intended to improve. The areas of discussion include Internet regulation, electronic voting and petitioning, monopoly and competition, and the concept of universal service
Standards and public policy by Shane M Greenstein( Book )
12 editions published between 2006 and 2012 in English and held by 265 libraries worldwide
Despite general agreement that technological standards are important, there is much less agreement on the central policy questions, such as whether markets choose the best standards, and what constitutes appropriate public policy toward standards. In this volume, leading researchers in the field focus on these key questions
Universal service in the digital age : the commercialization and geography of US Internet access by Shane M Greenstein( Book )
12 editions published in 1998 in English and held by 88 libraries worldwide
Many analysts anticipate a need to redefine universal service to account for Internet-related services and other combinations of communication and computing. This concern motivates a study of the geographic spread of the commercial Internet Service Provider (ISP) market suppliers of Internet access in the United States. The paper argues that two business models presently vie to diffuse commercially-oriented Internet-access across the US. One business model emphasizes a standardized national service, the other a customized local service. The paper then characterizes the location of over 14,000 access points, local phone numbers offered by commercial ISPs in the spring of 1997. Markets differ widely in their structure competitive to unserved. Just under three quarters of the US population has easy access to commercial Internet service providers, while approximately fifteen percent of the US population has costly access. Urban/rural coverage must be understood in the context of the different strategies of national/local providers
Dynamic modeling of the product life cycle in the commercial mainframe computer market, 1968-1982 by Shane M Greenstein( Book )
11 editions published in 1997 in English and held by 87 libraries worldwide
Abstract: This research investigates product life cycles in the commercial mainframe computer market. We show that empirical studies conducted at the product level are useful for investigating processes underlying product life cycles. We use hazard models with time-varying covariates to estimate the probability of product exit and Poisson models to estimate the probability of introduction. We measure the importance of different aspects of market structure, such as the degree of competitiveness, cannibalization, vintage, product niche and firm effects. We find some evidence of a relationship between the determinants of product exit and product entry
The evolution of advanced large scale information infrastructure in the United States by Shane M Greenstein( Book )
11 editions published in 1997 in English and held by 82 libraries worldwide
Abstract: Is private industry investing in backbone digital technology in a manner consistent with social policy? To address this question we assemble highly disaggregate data and compute indices for the geographic distribution of advanced backbone information technology in computing and telecommunications, focusing on recent changes in the indices. Our evidence suggests that the stock of advanced information technology capital, and access to it, became more equally distributed across the U.S. between the mid 1980s and early 1990s. In light of these findings there needs to be careful rethinking of the current policy concerns about the distribution of backbone technologies
The competitive crash in large-scale commercial computing by Timothy F Bresnahan( Book )
11 editions published in 1994 in English and held by 82 libraries worldwide
Abstract: We examine the factors underlying buyer demand for large Information Technology solutions in order to understand the competitive crash in large scale commercial computing. We examine individual buyer data from two periods. The first is in the mid 1980's, late in the period of a mature and stable large-systems market. The other period is in the early 1990's, very early in the diffusion of a new, competitive technology, client/server, when many buyers chose to wait for the new technology to mature. We clarify the implications of different theories of the competitive crash and then test them. The most popular theories are far wrong, while the correct view emphasizes the 'internal' adjustment costs to organizations making IT investments. Understanding buyer behavior not only illuminates the competitive crash, but also the factors underlying the slow realization of the social gains to Information Technology in large complex applications more generally
Building and delivering the virtual world : commercializing services for Internet access by Shane M Greenstein( Book )
12 editions published in 2000 in English and held by 81 libraries worldwide
Abstract: This study analyzes the service offerings of Internet Service Providers (ISPs), the commercial suppliers of Internet access in the United States. It presents data on the services of 2089 ISPs in the summer of 1998. By this time, the Internet access industry had undergone its first wave of entry and many ISPs had begun to offer services other than basic access. This paper develops an Internet access industry product code which classifies these services. Significant heterogeneity across ISPs is found in the propensity to offer these services, a pattern with an unconditional urban/rural difference. Most of the explained variance in behavior arises from firm-specific factors, with only weak evidence of location-specific factors for some services. These findings provide a window to the variety of approaches taken to build viable businesses organizations, a vital structural feature of this young market
How much better is bigger, faster & cheaper? : buyer benefits from innovation in mainframe computers in the 1980s by Kenneth H Brown( Book )
11 editions published in 1995 in English and held by 81 libraries worldwide
Abstract: This paper develops and estimates cost-of-living indexes (e.g., Fisher and Griliches [1995]) for measuring buyer benefits from technical change in the commercial mainframe computer industry in the 1980s. For this purpose we use a micro-econometric model of demand for product characteristics embodied in a computer system. The model highlights buyers' benefits from technical change when innovation decreases the price of characteristics or increases the range of available characteristics. This exercise follows in the spirit of Trajtenberg [1989]. Our main finding is that our utility-based cost-of-living index declines rapidly (approximately 10-15 percent per year). By historical standards for innovation, this rate is quite fast. Second, our estimates contrast with the rate of change in quality adjusted prices in mainframe computers (approximately 25-30 percent per year). Third, while large price declines induced increases in purchasing, most buyers began the 1980s with a 'small' mainframe system and still bought a small system at the end of the decade, even with rapidly declining mainframe prices and large extensions in computing capacity. The experience of the majority outweighs the benefits received by a few (with elastic demand), who took advantage of lower prices and extensions in the product space
Did computer technology diffuse quickly? : best and average practice in mainframe computers, 1968-1983 by Shane M Greenstein( Book )
13 editions published between 1993 and 1994 in English and held by 81 libraries worldwide
Abstract: An economy benefits from advances in technical frontiers only when new technology comes into general use. This paper measures the diffusion of computing equipment at a time when computing technology underwent dramatic technical improvement. These data shed light on the long lag between advances in computing technology and advances in economic performance of users. There is little evidence that long lags were produced by the 'slow diffusion' of new technology embodied in new hardware. 'Average practice' in computing advanced as rapidly as 'best practice,' lagging it by a maximum of 6 to 7 years
Estimating the welfare effects of digital infrastructure by Shane M Greenstein( Book )
12 editions published in 1996 in English and held by 81 libraries worldwide
Abstract: While much economic policy presumes that more information infrastructure yields higher economic returns, little empirical work measures the magnitudes of these returns. We examine investment by local exchange telephone companies in fiber optic cable, ISDN lines and signal seven software, infrastructure which plays an essential role in bringing digital technology to local telephone networks. We estimate the elasticity of the derived demand for infrastructure investment faced by local exchange companies, controlling for factors such as local economic activity and the political disposition of state regulators. Our model postulates a regulated profit maximizing local exchange firm and a regulatory agency with predetermined political leanings in favor of consumer prices or firm profits. The model accounts for variation in state regulation and local economic conditions. In all our estimates we find that consumer demand is sensitive to investment in modern infrastructure, particularly as represented by fiber optic cable. Our estimates imply that infrastructure investment is responsible for a substantial fraction of the recent growth in consumer surplus and business revenue in local telecommunication services
From superminis to supercomputers : estimating surplus in the computing market by Shane M Greenstein( Book )
11 editions published in 1994 in English and held by 80 libraries worldwide
Abstract: Innovation was rampant in the computer industry during the late 1960s and the 1970s. Did innovation vastly extend the capabilities of computers or simply reduce the costs of doing the same thing? This question goes to the heart of whether the rate of decline in 'constant-quality' computing prices incorrectly identifies the sources of improvement and benefits from technological change. This paper argues that innovation freed computers of technical constraints to providing new services, manifesting many new capabilities in systems with larger capacity. Both anecdotal and quantitative evidence suggest that many buyers adopted new systems to get access to these new capabilities, not solely to take advantage of lower prices. The analysis divides itself into several related questions. First, what innovations in this period are associated with extensions of capabilities? Second, do buyers adopt products that embody extensions of capabilities? Third, how does a measurement framework represent that action? Are extensions embodied only in increases in capacity or are they embodied in other measurable features of a computer system as well?
Digital dispersion : an industrial and geographic census of commercial internet use by Christopher Forman( Book )
9 editions published in 2002 in English and held by 69 libraries worldwide
Our study provides the first census of the dispersion of Internet technology to commercial establishments in the United States. We distinguish between participation, that is, use of the Internet because it is necessary for all business (e.g., email and browsing) and enhancement, that is, adoption of Internet technology to enhance computing processes for competitive advantage (e.g., electronic commerce). Employing the Harte Hanks Market Intelligence Survey, we examine adoption of the Internet at 86,879 commercial establishments with 100 or more employees at the end of 2000. Using routine statistical methods, we focus on answering questions about economy-wide outcomes: Which industries had the highest and lowest rates of participation and enhancement? Which cities, states and industries had a typical experience and which did not? We arrive at three conclusions. First, participation and enhancement display contrasting patterns of dispersion. In a majority of industries participation has approached saturation levels, while enhancement occurs at lower rates and with dispersion reflecting long standing industrial differences in use of computing. Second, the creation and use of the Internet does not eliminate the importance of geography. Leading areas are widespread, whereas laggards are more common in smaller urban areas and some rural areas. However, the distribution of industries across geographic regions explains much of the difference in rates of adoption of the Internet in different areas. Third, commercial Internet use is quite dispersed, more so than previous studies show
How did location affect adoption of the commercial internet? : global village, urban density, and industry composition by Christopher Forman( Book )
9 editions published in 2003 in English and held by 69 libraries worldwide
Abstract: The authors test opposing theories on how urban locations influenced the diffusion of Internet technology. They find evidence that, controlling for industry, participation in the Internet is more likely in rural areas than in urban areas. Nevertheless, talk of the dissolution of cities is premature. Frontier Internet technologies appear more often at establishments in urban areas, even with industry controls. Major urban areas also contain many establishments from information technology-intensive industries, whose presence could reinforce the concentration of frontier Internet technologies in these areas. However, information technology-intensive industries are numerous and widespread. Hence, so is the use of frontier technology
Differentiation strategy and market deregulation : local telecommunication entry in the late 1990s by Shane M Greenstein( Book )
9 editions published in 2003 in English and held by 68 libraries worldwide
Abstract: The authors examine the role of differentiation strategies for entry behavior in markets for local telecommunication services in the late 1990s. Whereas the prior literature has used models of interaction among homogenous firms, this research is motivated by the claim of entrants that they differ substantially in their product offerings and business strategies. Exploiting a new, detailed data set of Competitive Local Exchange Carriers (CLECs) entry into over 700 U.S. cities, the authors take advantage of recent developments in the analysis of entry and competition among differentiated firms. They test and reject the null hypothesis of homogeneous competitors. They also find strong evidence that CLECs account for both potential market demand and the business strategies of competitors when making their entry decisions. This suggests that firms' incentives to differentiate their services should shape the policy debate for competitive local telecommunications
Coordination vs. differentiation in a standards war : 56K modems by Angelique Augereau( Book )
8 editions published in 2004 in English and held by 67 libraries worldwide
"56K modems were introduced under two competing incompatible standards. We show the importance of competition between Internet Service Providers in the adoption process. We show that ISPs were less likely to adopt the technology that more competitors adopted. This result is particularly striking given that industry participants expected coordination on one standard or the other. We speculate about the role of ISP differentiation in preventing the market form achieving standardization until a government organization intervened"--National Bureau of Economic Research web site
Technology adoption in and out of major urban areas : when do internal firm resources matter most? by Christopher Forman( Book )
8 editions published in 2005 in English and held by 55 libraries worldwide
"How much do internal firm resources contribute to technology adoption in major urban locations, where the advantages from agglomeration are greatest? The authors address this question in the context of a business's decision to adopt advanced Internet technology. Drawing on a rich data set of adoption decisions by 86,879 U.S. establishments, the authors find that the marginal contribution of internal resources to adoption is greater outside of a major urban area than inside one. Agglomeration is therefore less important for highly capable firms. The authors conclude that firms behave as if resources available in cities are substitutes for both establishment-level and firm-level internal resources"--National Bureau of Economic Research web site
Economic experiments and neutrality in internet access by Shane M Greenstein( file )
7 editions published in 2007 in English and held by 48 libraries worldwide
Economic experiments yield lessons to firms that can be acquired only through market experience. Economic experiments cannot take place in a laboratory; scientists, engineers, or marketing executives cannot distill equivalent lessons from simply building a prototype or interviewing potential customers and vendors. The historical record illustrates that economic experiments were important for value creation in Internet access markets. In general, industry-wide returns from economic experiments exceed private returns, with several important exceptions. Those conclusions motivate an inquiry into whether regulatory policy can play a role in fostering the creation of value. The net neutrality debate is reinterpreted through this lens. A three part test is proposed for encouraging economic experiments from both broadband carriers and providers of complementary services
The diffusion of the Internet and the geography of the digital divide in the United States by Shane M Greenstein( file )
8 editions published in 2006 in English and held by 48 libraries worldwide
"This paper analyses the rapid diffusion of the Internet across the United States over the past decade for both households and firms. We put the Internet's diffusion into the context of economic diffusion theory where we consider costs and benefits on the demand and supply side. We also discuss several pictures of the Internet's physical presence using some of the current main techniques for Internet measurement. We highlight different economic perspectives and explanations for the digital divide, that is, unequal availability and use of the Internet"--National Bureau of Economic Research web site
