Description

"

During the 1980s and into this decade, U.S. businesses poured billions of dollars into computers and other information technology. Yet the productivity performance of the U.S. economy in the 1980s remained lackluster--especially in the service sector--leading many observers to suspect that companies were not getting their money's worth from these high-tech investments. At the same time, academic research found little evidence of a productivity payoff. But have the tables now turned With an apparent improvement in productivity in recent years, much academic and popular opinion now suggests that the payback is at hand or just around the corner.

As the nation embarks on a major effort to develop an Information Superhighway, it is critical for policymakers, opinion leaders, and others to understand the contribution and role of information technology in the economy during recent decades. This book provides a straightforward guide to the economic issues underlying the debates about these issues, using quantitative and historical analysis, supplemented with interviews of small and large service-sector companies.

To set the stage, Daniel Sichel reviews the debates over the role of computers and summarizes the essential facts about computer use, with a particular emphasis on software. Going beyond basic facts, Sichel describes an economic framework for assessing the aggregate economic impact of computers in recent decades and for looking ahead at this impact in the future. Quantitative estimates from this framework, along with supporting historical and interview evidence, place limits on the contribution of computers to the overall economy. When compared to the size of the slowdown in productivity growth in the early 1970s, the overall impact of computers appears relatively modest, in part because the share of computers in the nation's capital stock is surprisingly small. Looking ahead, Sichel also raises questions as to whether computers are likely to solve the nation's productivity woes in the future.

Reviews

"For more than a decade, American corporations have been shoveling billions of dollars in computers down a black hole, with no reponse at all from the sluggish growth rate of American productivity. Dan Sichel's pathbreaking book helps us to explain the computer paradox by showing that computer hardware is too small a share of the capital stock to matter much, and that there are reasons to doubt a future surge in the contribution of computer hardware and software growth." Robert J. Gordon, Professor of Economics, Northwestern University

"The great productivity puzzle of the last two decades is why the much touted computer revolution has not produced faster economic growth. Dan Sichel's dispassionate analysis articulately confronts hype with facts and provides deep insights into the nature of the relationship between computer hardware and software, productivity, and economic growth. It is a major contribution to our understanding of this critical area." Richard E. Quandt, Professor Emeritus, Princeton University and Senior Adviser, Andrew W. Mellon Foundation
