Too much of a good thing? Why altruism can harm the environment?

Success of eco-labeling schemes, broadly defined, varies among products and across countries. Based on a simple theoretical framework, we show that the nature of environmental attributes among products (i.e., private versus public) and the consumer type (i.e., egoist versus altruist) shape the overall performance of such schemes. In addition, we demonstrate that altruistic consumers exhibiting a too high willingness to pay for the eco-labeled product can inadvertently prevent egoistic consumers from purchasing it, leading to a sub-optimal outcome in terms of environmental performance. Several policy and managerial implications are drawn.     

Coastal blue space and wellbeing research: looking beyond western tides

ABSTRACT

In this paper we focus on coastal blue spaces and the ways in which they have been advocated as beneficial for health and wellbeing in the context of leisure practices. We offer a reassessment of some of the claims made in this growing body of literature, highlighting the diverse cultural practices at the coast across different geographical contexts, particularly for those communities that have experienced exclusion due to ethnicity, culture, and income. We then discuss conceptions of coastal blue space and wellbeing within the context of Aotearoa New Zealand, a bi-cultural nation in which indigenous knowledges connected to both wellbeing and leisure in the outdoor world are impacting dominant (white, colonial) discourses, policies and practices. We illustrate that a Māori world view embraces different practices and assumptions about what water means and how relationships with water are made including through leisure practices. Aotearoa New Zealand provides a revealing cultural context for re-assessing and indeed challenging Eurocentric assumptions about blue spaces as sites of wellbeing. More widely we suggest that it is timely to anchor blue space and wellbeing research to different ‘worlds’; that looking in to reach out and expanding research agendas is a useful and important enterprise.     

Do people trust more when they are happy or when they are sad? Evidence from an experiment

This paper deals with the role played by incidental emotions on trust decisions. Based on a laboratory experiment with monetary incentives, we explore the way positive and negative emotions impact transfers in a trust game. In addition, we investigate the mechanism through which risk intervenes in the relationship between emotions and trust. Our results suggest that negative emotions influence trust positively, whereas positive emotions decrease trust. This effect disappears once risk is included to the game. Furthermore, we found that transfer in the trust game is driven by other‐regarding preferences and by risk preferences.     

Environment and Food Safety in Agriculture: Are Labels Efficient?

In this article, we try to elicit whether an information on food safety is consistent with a more environmental‐friendly agriculture. As the policy makers generally intervene to limit negative externalities in agriculture on the supply side, is a labelling policy an efficient way to reduce pollution levels in this sector? The intuitive reason of a food safety label rests on the fact that consumers seem to be more concerned with information on food safety aspects than on environmental ones. In a vertical differentiation model, we analyse the impacts of labels mentioning food safety and environmental aspects, on firms' profits, consumers' surplus and pollution levels. Given our main assumption that food safety and environmental consequences are directly linked, our principal results show that a labelling policy on food safety can be efficient from an environmental point of view, depending on the initial healthy products proportion in the market. Another result is based on the fact that a label policy can reduce consumer's surplus.     

Popularity of Brand Posts on Brand Fan Pages: An Investigation of the Effects of Social Media Marketing

Social media outlets constitute excellent vehicles for fostering relationships with customers. One specific way to do this is to create brand fan pages on social networking sites. Companies can place brand posts (containing videos, messages, quizzes, information, and other material) on these brand fan pages. Customers can become fans of these brand fan pages, and subsequently indicate that they like the brand post or comment on it. This liking and commenting on brand posts reflects brand post popularity. In this article, we determine possible drivers for brand post popularity. We analyze 355 brand posts from 11 international brands spread across six product categories.Results show that positioning the brand post on top of the brand fan page enhances brand post popularity. But the findings also indicate that different drivers influence the number of likes and the number of comments. Namely, vivid and interactive brand post characteristics enhance the number of likes. Moreover, the share of positive comments on a brand post is positively related to the number of likes. The number of comments can be enhanced by the interactive brand post characteristic, a question. The shares of both positive and negative comments are positively related to the number of comments. Managers of brands that operate brand fan pages can be guided by our research with regards to deciding which characteristics or content to place at brand posts.     

Cost-effectiveness of glatiramer acetate and interferon beta-1a for relapsing-remitting multiple sclerosis,based on the CombiRx study

Background:

To assess the cost-effectiveness of the Disease Modifying Treatments (DMT), Glatiramer Acetate (GA) and Interferon beta-1a (IFN) in monotherapy alone and in combination for the prevention of relapses among Spanish patients aged between 18–60 years old with established Relapsing–Remitting Multiple Sclerosis (RRMS).

Methods:

A Markov model was developed to represent the transition of a cohort of patients over a 10 year period using the perspective of the Spanish National Health Service (NHS). The model considered five different health states with 1-year cycles including without relapse, patients with suspect, non-protocol defined and protocol defined exacerbations, as well as a category information lost. Efficacy data was obtained from the 3-year CombiRx Study. Costs were reported in 2013 Euros and a 3% discount rate was applied for health and benefits. Deterministic results were presented as the annual treatment cost for the number of relapses. A probabilistic sensitivity analysis was performed to test the robustness of the model.

Results:

Deterministic results showed that the expected annual cost per patient was lower when treated with GA (€13,843) compared with IFN (€15,589) and the combined treatment with IFN?+?GA (€21,539). The annual number of relapses were lower in the GA cohort with 3.81 vs 4.18 in the IFN cohort and 4.08 in the cohort treated with IFN?+?GA. Results from probabilistic sensitivity analysis showed that GA has a higher probability of being cost-effective than treatment with IFN or IFN?+?GA for threshold values from €28,000 onwards, independent of the maximum that the Spanish NHS is willing to pay for avoiding relapses.

Conclusion:

GA was shown to be a cost-effective treatment option for the prevention of relapses in Spanish patients diagnosed with RRMS. When GA in monotherapy is compared with INF in monotherapy and IFN?+?GA combined, it may be concluded that the first is the dominant strategy.     

Institutionalising corporate citizenship: the case of Barloworld and its ‘Employee Value Creation’ process

This article investigates the institutionalisation of corporate citizenship (CC) at Barloworld Limited, a diversified industrial enterprise. It describes a model that relates corporate identity, stakeholder engagement, internal structure and accountability and applies this model to a case study of Barloworld. The case study illustrates the importance of the company's corporate identity, or guiding philosophy, and its impact on organisational culture and management processes. The company's ‘Employee Value Creation’ strategy has comprehensively overhauled employee relations to achieve a high degree of employee commitment and participation. It institutionalises CC by integrating social or environmental issues into the organisation ‘from below’ and by helping employees understand why such issues matter to the organisation and are relevant to employees' responsibilities. Whereas the relevant literature emphasises the possible role of CC in creating employee commitment, this case study illustrates the reverse possibility: that employee commitment can be a catalyst for integrating CC into a company.     

Can Ecolabeling Schemes Preserve the Environment?

A three-stage game of production technology, signal and price competition is developed to study the impact of eco-labeling, in a duopoly model of vertical product differentiation. The production technology and the subsequent pollution level are non-observable by consumers. The only way to inform consumers about the environmental quality of the product is to stick an ecolabel on it. However, a polluting firm may also usurp the ecolabel by incurring a certain cost. By assuming that consumers are altruistic and willing to pay for environmental quality, we show that ecolabels can reduce the pollution level. Finally and importantly, under restrictive conditions on labeling cost, ecolabeling can constitute to some extent an environmentally effective and economically efficient policy. However, ecolabeling cannot alone internalize the whole negative externality until the optimum point.
