Profiling potential green electricity tariff adopters: green consumerism as an environmental policy tool?

Green electricity tariffs are one means by which green consumers can contribute to a more sustainable future. This paper profiles potential adopters of green electricity tariffs. Potential adoption is measured in terms of respondents' willingness to pay a premium for green energy in a national survey of the UK population. Hypotheses based principally on the cognitive–behavioural literature on green consumerism and green energy markets are developed. These are tested using a broad range of variables, which are grouped into three categories (demographic, attitudinal and behavioural). Consistent with past research, the empirical analyses find that attitudinal variables best characterize potential adopters. Further, potential adopters are found to have higher income, be better informed with respect to energy matters, show concern for the environment and believe that individual actions can make a difference to environmental decay. The implications of these findings for marketing and environmental policy are explored. Copyright © 2010 John Wiley & Sons, Ltd and ERP Environment.

The Moral Authority of Ecotourism: A Critique

The paper argues that in debates on the role of tourism in bringing about development in the developing world, ecotourism has acquired a certain moral authority. It is often compared favourably to other categories of tourism, most notably mass tourism, based on its ability to combine conservation and development, categories that are often considered to exist in an antagonistic relationship. The paper seeks to challenge this moral authority. Others have attempted to do this, typically arguing that ecotourism can lead to mass tourism and consequently the same destructive tendencies, or that it is simply conscience salving for the western middle class. However the argument put forward here is a different one – that ecotourism as a tool for integrated conservation and development, widely advocated within conservation non-governmental organisations (NGOs), ties communities’ development prospects to a pre-existing relationship with their immediate natural environment. Basing development upon this relationship may offer some benefits to local communities, but at the same time the championing of such eco-development precludes a discussion of thoroughgoing economic development, development that would transform this relationship. The paper concludes that the championing of ecotourism reflects low horizons for development and that its moral credentials are highly questionable.     

Cultural theory and risk perception: a proposal for a better measurement

Why do members of the public disagree – sharply and persistently – about facts on which expert scientists largely agree? We designed a study to test a distinctive explanation: the cultural cognition of scientific consensus. The ‘cultural cognition of risk’ refers to the tendency of individuals to form risk perceptions that are congenial to their values. The study presents both correlational and experimental evidence confirming that cultural cognition shapes individuals’ beliefs about the existence of scientific consensus, and the process by which they form such beliefs, relating to climate change, the disposal of nuclear wastes, and the effect of permitting concealed possession of handguns. The implications of this dynamic for science communication and public policy‐making are discussed.     

Knowledge sharing,work–family conflict and supervisor support: investigating a three-way effect

Despite the importance of knowledge sharing in competitive environments, there is a paucity of studies examining the relationship between employee knowledge sharing and work–family conflict. Drawing on insights from conservation of resources theory, this study investigated how employees may reduce their knowledge-sharing behaviors when they experience resources lost from work interference with family (WIF) or family interference with work (FIW). Furthermore, the role of supervisor support in the relationship among WIF, FIW and knowledge sharing was explored as a valuable resource. Using data collected from 159 employees in South Korea, we found support that WIF is negatively related to knowledge sharing. In addition, the role of supervisor support in the relationship among WIF, FIW and knowledge sharing was the strongest when WIF is low and FIW is high, thus supporting the hypothesized a three-way effect. Theoretical and practical implications are discussed.     

Local Residential Sorting and Public Goods Provision: A Classroom Demonstration

This classroom exercise illustrates the Tiebout (1956) hypothesis that residential sorting across multiple jurisdictions leads to a more efficient allocation of local public goods. The exercise places students with heterogeneous preferences over a public good into a single classroom community. A simple voting mechanism determines the level of public good provision in the community. Next, the classroom is divided in two, and students may choose to move between the two smaller communities, sorting themselves according to their preferences for public goods. The exercise places cost on movement at first, then allows for costless sorting. Students have the opportunity to observe how social welfare rises through successive rounds of the exercise, as sorting becomes more complete. They may also observe how immobile individuals can become worse off because of incomplete sorting when the Tiebout assumptions do not hold perfectly.

Cost of Equity Capital and Additionality of Brazilian Renewable Energy Projects Under the Clean Development Mechanism

The purpose of this study was to assess additionality and the practice of estimating the cost of equity capital in 70 renewable energy projects in Brazil. Forty projects demonstrated additionality by means of financial analysis. No strong or clear relationships were found between project characteristics and the financial method used to demonstrate additionality. Among projects that used financial analysis, the evaluation often employed the risk-free rate. Failure to add any risk premium to projects of this nature suggests a certain analytical carelessness, perhaps induced by the innovative or experimental nature of these projects.
