American public policy has had a long history of technological optimism. The success of the United States in research and development contributes to this optimism and leads many to assume that there is a technological fix for significant national problems. Since World War II the federal government has been the major supporter of commercial research and development efforts in a wide variety of industries. But how successful are these projects? And equally important, how do economic and policy factors influence performance and are these influences predictable and controllable? Linda Cohen, Roger Noll, and three other economists address these questions while focusing on the importance of R&D to the national economy. They examine the codependency between technological progress and economic growth and explain such matters as why the private sector often fails to fund commercially applicable research adequately and why the government should focus support on some industries and not others. They also analyze political incentives facing officials who enact and implement programs and the subsequent forces affecting decisions to continue, terminate, or redirect them. The central part of this book presents detailed case histories of six programs: the supersonic transport, communications satellites, the space shuttle, the breeder reactor, photovoltaics, and synthetic fuels. The authors conclude with recommendations for program restructuring to minimize the conflict between economic objectives and political constraints.
Each new generation of commercial aircraft produces less noise and fewer emissions per passenger-kilometer (or ton-kilometer of cargo) than the previous generation. However, the demand for air transportation services grows so quickly that total aircraft noise and emissions continue to increase. Meanwhile, federal, state, and local noise and air quality standards in the United States and overseas have become more stringent. It is becoming more difficult to reconcile public demand for inexpensive, easily accessible air transportation services with concurrent desires to reduce noise, improve local air quality, and protect the global environment against climate change and depletion of stratospheric ozone. This situation calls for federal leadership and strong action from industry and government. U.S. government, industry, and universities conduct research and develop technology that could help reduce aircraft noise and emissions-but only if the results are used to improve operational systems or standards. For example, the (now terminated) Advanced Subsonic Technology Program of the National Aeronautics and Space Administration (NASA) generally brought new technology only to the point where a system, subsystem model, or prototype was demonstrated or could be validated in a relevant environment. Completing the maturation process-by fielding affordable, proven, commercially available systems for installation on new or modified aircraft-was left to industry and generally took place only if industry had an economic or regulatory incentive to make the necessary investment. In response to this situation, the Federal Aviation Administration, NASA, and the Environmental Protection Agency, asked the Aeronautics and Space Engineering Board of the National Research Council to recommend research strategies and approaches that would further efforts to mitigate the environmental effects (i.e., noise and emissions) of aviation. The statement of task required the Committee on Aeronautics Research and Technology for Environmental Compatibility to assess whether existing research policies and programs are likely to foster the technological improvements needed to ensure that environmental constraints do not become a significant barrier to growth of the aviation sector.
