Estimating the Welfare Effects of Digital Infrastructure


Book Description

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.




Down to the Wire


Book Description

In recent years, regulators and businesses have struggled to keep pace with an onslaught of new technologies that has dramatically changed the world's telecommunications networks. This book gathers together research intended for those who must grapple with these changes -- the people who must decide whether and how to deploy new telecommunications technologies, and those who must regulate the technologies. The research is divided into three sections focusing on the past, present and future of telecommunications innovations. The first section, Lessons from the Past, examines what lessons concerning adoption and regulation can be learned by studying the diffusion of recent telecommunications technologies. The second section, Decision Making with Respect to Diffusing Technologies, examines possible improvements to the decision-making processes used by companies and regulators in the face of limited information and dynamic markets. The final section, Public Policy and Future Diffusion, examines public policy implications for future technologies.




Estimating the Distribution of Welfare Effects Using Quantiles


Book Description

This paper proposes a framework to model welfare effects that are associated with a price change in a population of heterogeneous consumers. The framework is similar to that of Hausman and Newey ( Econometrica, 1995, 63, 1445–1476), but allows for more general forms of heterogeneity. Individual demands are characterized by a general model that is nonparametric in the regressors, as well as monotonic in unobserved heterogeneity, allowing us to identify the distribution of welfare effects. We first argue why a decision maker should care about this distribution. Then we establish constructive identification, propose a sample counterparts estimator, and analyze its large‐sample properties. Finally, we apply all concepts to measuring the heterogeneous effect of a change of gasoline price using US consumer data and find very substantial differences in individual effects across quantiles.




Measuring Welfare Gains from Better Quality Infrastructure


Book Description

"Projects and reforms targeting infrastructure services can affect consumer welfare through changes in the price, coverage, or quality of the services provided. The benefits of improved service quality-while significant-are often overlooked because they are difficult to quantify. This paper reviews methods of evaluating the welfare implications of changes in the quality of infrastructure services within the broader theoretical perspective of welfare measurement. The study outlines the theoretical assumptions and data requirements involved, illustrating each method with examples that highlight common methodological features and differences. The paper also presents the theoretical underpinnings and potential applications of a new approach to analyzing the effects of interruptions in the supply of infrastructure services on household welfare."--Cover verso.




Handbook of Research on Global Diffusion of Broadband Data Transmission


Book Description

Explores broadband adoption and the digital divide through a global perspective. Presents research on constructs such as relative advantage, utilitarian outcomes, hedonic outcomes, and service quality. Provides multicultural insight into what factors influence consumers' decisions to adopt broadband.




Escaping Satiation


Book Description

The collection of papers presented in this special issue arose out of two events. The first was the symposium "Escaping Satiation - Increasing Product Variety, Preference Change and the Demand Side of Economic Growth" which was held at the Max Planck Institute in Jena, Germany, in December 1997. The Fritz Thyssen Foundation provided financial support for this seminal symposium which is gratefully acknowledged. Wilhelm Ruprecht was of great help in preparing the symposium and I would like to express my gratitude to hirn on this occasion. Many stimulating exchanges with hirn over the past few years while he was a research associate at the Institute working on long term changes in consumption convinced me of the relevance and importance of this problem for understanding modem economic growth. I also owe thanks to many people who encouraged me to go ahead with the symposium, among them Stanley Metcalfe, Carl Christian von Weizsäcker, and also Ehud Zuscovitch, who died so unexpectedly last year.

The Economics of Digitization


Book Description

The increasing creation, support, use and consumption of digital representation of information touches a wide breadth of economic activities. This digitization has transformed social interactions, facilitated entirely new industries and undermined others and reshaped the ability of people - consumers, job seekers, managers, government officials and citizens - to access and leverage information. This important book includes seminal papers addressing topics such as the causes and consequences of digitization, factors shaping the structure of products and services and creating an enormous range of new applications and how market participants make their choices over strategic organization, market conduct, and public policies. This authoritative collection, with an original introduction by the editors, will be an invaluable source of reference for students, academics and practitioners with an interest in the economics of digitisation and the digital economy.




Visible Costs and Invisible Benefits


Book Description

This book examines the historic role of professional and demanding military customers in industrial development. Particular emphasis is paid to public procurement of military equipment as a catalyst for innovation; and the civilian commercialization of military technologies (from gunpowder and cannons to submarines, missiles and aircraft) is documented by many case illustrations that show how macro-level productivity advance has been generated. A complementary volume to Advancing Public Procurement as Industrial Policy (2010), which focused on the spillover effects of the Swedish combat aircraft, Gripen, in this book Gunnar Eliasson widens the perspective to cover product development across the Swedish defense industry, with an emphasis on regional economic development and macro-economics, inter alia through the involvement of Saab (aircraft) and Kockums (submarines) in partnership ventures in Australia, Norway and Brazil. The volume is organized into four parts. Part one examines the historical transformation of the Swedish economy over the past three centuries from agriculture and raw materials to an advanced industrial economy. Part two presents detailed case studies to illustrate the spillover effects of procurement projects and military-industrial partnerships. Part three explains the spillover phenomenon theoretically within a dynamic micro- to macro-economic perspective. Particular emphasis is placed on the empirical credibility of model-based economy-wide and dynamic cost-benefit calculations. The book concludes with a section on fostering industrial development through public procurement. The result is a book that will appeal to economists in the industrial economics and management fields; to technical, marketing and purchasing executives in business; and to policy makers in public procurement concerned with innovation and long-run industrial development.
