Science, Technology, and Public Policy

Many economists have long held that carbon pricing—either through a carbon tax or cap-and-trade—is the most cost-effective way to decarbonize energy systems, along with subsidies for basic research and development. Meanwhile, green innovation and industrial policies aimed at fostering low-carbon energy technologies have proliferated widely. Most of these predate direct carbon pricing. Low-carbon leaders such as California and the European Union (EU) have followed a distinct policy sequence that helps overcome some of the political challenges facing low-carbon policy by building economic interest groups in support of decarbonization and reducing the cost of technologies required for emissions reductions. However, while politically effective, this policy pathway faces significant challenges to environmental and cost effectiveness.

Expert elicitations are now frequently used to characterize uncertain future technology outcomes. However, their usefulness is limited, in part because: estimates across studies are not easily comparable; choices in survey design and expert selection may bias results; and overconfidence is a persistent problem. The authors provide quantitative evidence of how these choices affect experts' estimates.

In order to make R&D funding decisions to meet particular goals, such as mitigating climate change or improving energy security, or to estimate the social returns to R&D, policy makers need to combine the information provided in this study on cost reduction potentials with an analysis of the macroeconomic implications of these technological changes. The authors conclude with recommendations for future directions on energy expert elicitations.

Based on multi-archival research, this article explores the significance of Franco-Indian nuclear relations against the backdrop of Anglo-American endeavours to censor information related to atomic energy and to secure control of strategic minerals during the early Cold War.

Despite the nuclear accident at the Fukushima-Daiichi plant in Japan, a growing number of countries are interested in expanding or introducing nuclear energy. However, nuclear energy production and nuclear waste disposal give rise to pressing ethical questions that society needs to face. This book takes up this challenge with essays by an international team of scholars focusing on the key issues of risk, justice and democracy. The essays consider a range of ethical issues including radiological protection, the influence of gender in the acceptability of nuclear risk, and environmental, international and intergenerational justice in the context of nuclear energy
