Informed Public Preferences for Electricity Portfolios with CCS and Other Low‐Carbon Technologies

Public perceptions of carbon capture and sequestration (CCS) and other low‐carbon electricity‐generating technologies may affect the feasibility of their widespread deployment. We asked a diverse sample of 60 participants recruited from community groups in Pittsburgh, Pennsylvania to rank 10 technologies (e.g., coal with CCS, natural gas, nuclear, various renewables, and energy efficiency), and seven realistic low‐carbon portfolios composed of these technologies, after receiving comprehensive and carefully balanced materials that explained the costs and benefits of each technology. Rankings were obtained in small group settings as well as individually before and after the group discussions. The ranking exercise asked participants to assume that the U.S. Congress had mandated a reduction in carbon dioxide emissions from power plants to be built in the future. Overall, rankings suggest that participants favored energy efficiency, followed by nuclear power, integrated gasification combined‐cycle coal with CCS and wind. The most preferred portfolio also included these technologies. We find that these informed members of the general public preferred diverse portfolios that contained CCS and nuclear over alternatives once they fully understood the benefits, cost, and limitations of each. The materials and approach developed for this study may also have value in educating members of the general public about the challenges of achieving a low‐carbon energy future.     

Now What Do People Know About Global Climate Change? Survey Studies of Educated Laypeople

In 1992, a mental‐models‐based survey in Pittsburgh, Pennsylvania, revealed that educated laypeople often conflated global climate change and stratospheric ozone depletion, and appeared relatively unaware of the role of anthropogenic carbon dioxide emissions in global warming. This study compares those survey results with 2009 data from a sample of similarly well‐educated laypeople responding to the same survey instrument. Not surprisingly, following a decade of explosive attention to climate change in politics and in the mainstream media, survey respondents in 2009 showed higher awareness and comprehension of some climate change causes. Most notably, unlike those in 1992, 2009 respondents rarely mentioned ozone depletion as a cause of global warming. They were also far more likely to correctly volunteer energy use as a major cause of climate change; many in 2009 also cited natural processes and historical climatic cycles as key causes. When asked how to address the problem of climate change, while respondents in 1992 were unable to differentiate between general “good environmental practices” and actions specific to addressing climate change, respondents in 2009 have begun to appreciate the differences. Despite this, many individuals in 2009 still had incorrect beliefs about climate change, and still did not appear to fully appreciate key facts such as that global warming is primarily due to increased concentrations of carbon dioxide in the atmosphere, and the single most important source of this carbon dioxide is the combustion of fossil fuels.     

THE SOLOW RESIDUAL FOR AUSTRALIA: TECHNOLOGY SHOCKS OR FACTOR UTILIZATION?

This paper presents evidence which implies that fluctuations in the Solow residual for Australia do not solely reflect technology shocks. Recent work suggests that the Solow residual is a noisy measure of technology shocks. One source of noise in the standard measure of the Solow residual is changes in factor utilization. In this paper a structural vector autoregression model for capacity utilization and the Solow residual is estimated. A transitory shock is identified that accounts, for about 30% of the short term variation in the Solow residual and virtually 100% of the variation in capacity utilization at all horizons.

Nondestructive creation: Entrepreneurship and management research in the study of growth

Economists’ focus on institutions in explaining economic growth, while important, can obscure the significant role played by individual entrepreneurs and the process of entrepreneurship. The prevailing view of entrepreneurship in economics (which continues to shape prevailing public policies) centers on Schumpeter's famous concept of “creative destruction.” In the context of sustained high levels of economic growth, as in the recent American experience, I focus on a different feature of entrepreneurship—“nondestructive creation,” in which the uncoordinated contest of ideas and search for new applications of existing ideas generate growth. And this nondestructive creation should be analyzed and can be fostered.     

Evaluating Risk Communications: Completing and Correcting Mental Models of Hazardous Processes, Part II

We propose a decision-analytic framework, called the mental models approach , for evaluating the impact of risk communications. It employs multiple evaluation methods, including think-aloud protocol analysis, problem solving, and a true-false test that allows respondents to express uncertainty about their answers. The approach is illustrated in empirical comparisons of three brochures about indoor radon.     

Behaviour Exchange Systems Training: The ‘BEST’ Approach for Parents Stressed by Adolescent Drug Problems

Parents are challenged in the adolescent years by attempts to increase adolescent responsibility while also managing separation issues. Adolescent drug use can exacerbate parental concerns. Parental fears and anxieties surrounding adolescent drug use can undermine opportunities to respond effectively. This paper describes the theoretical rationale for, and early experience of delivering, a brief intervention program designed to assist parents coping with adolescent drug problems. The program emerges out of a hybrid of systems and behaviour therapy principles and has been designed to address issues associated with parenting characterised by a high level of emotional involvement and/or ineffective parental control. Group work encouraging more adolescent responsibility-taking can assist parents disabled by feelings of guilt and failure. As parents develop emotional independence from adolescent behaviour, an appropriate expectation for adolescent control is established.
