In the face of existing obstacles in the interdisciplinary research on sustainable consumption behaviors, we argue for the need of an integrative framework from an interdisciplinary perspective. Such a framework is presented in the form of a three-dimensional cube model of sustainable consumption behavior (SCB-cube) extended by a fourth impact dimension. The model has two purposes for application: First, to systematize existing research on different behaviors on a common taxonomy and second, to facilitate the selection of relevant sustainable consumption behaviors in social sustainability research based on impact. We critically appraise existing intent-and impact-based research approaches on the four key dimensions of the SCBcube, focusing on the ecological and socio-economic impacts of consumption behaviors. Recommendations for the selection of relevant behaviors for empirical behavioral research are given, using the SCB-cube as a guiding heuristic. The main audience for this model is social science researchers measuring sustainable consumer behaviors on the individual level. Copyright

From the very beginning of the Internet, a decisive shift from supplier power to consumer power was predicted by several authors and is still maintained in recent literature. Although the Internet has grown rapidly within the last years and electronic markets have evolved, a theoretical framework for consumer power on the Internet still cannot be identified. Few authors have taken efforts to apply common concepts of power theory to the characteristics of the Internet. Based on the concept of French and Raven, this paper analyses consumer power in traditional markets and then compares it to the situation on the Internet. This comparison shows that the Internet enables consumers (a) to overcome most information asymmetries that characterize traditional consumer markets and thus obtain high levels of market transparency, (b) to easily band together against companies and impose sanctions via exit and voice, and (c) to take on a more active role in the value chain and influence products and prices according to individual preferences. A broad literature review reveals that empirical findings confirm these hypotheses to a great extent. The authors conclude by summarizing the results and drawing implications from two different angles, namely from a marketing and a consumer policy perspective.

Purpose The purpose of this paper is to provide the conceptual basis of collaborative fashion consumption (CFC) as a possible path toward more sustainable clothing. A definition and a typology of CFC are introduced and possible environmental effects of CFC are structured and discussed. This provides a solid conceptual basis for future empirical studies on CFC as an element of more sustainable consumption. Design/methodology/approach This paper is written mainly based on a review of the more recent literature on collaborative consumption, as well as of older papers about related concepts like sustainable service systems and eco-efficient services. The proposed CFC typology and the structure of environmental effects are developed using both a deductive and an inductive process, and then by transferring existing structures to this specific field and challenging them by assigning practical examples. Findings The main contributions of this paper are the definition and typology of CFC and the structure for assessing its environmental effects. Research limitations/implications The findings provide a conceptual basis for future empirical research on CFC. Practical implications For practitioners, the CFC typology and the structure of environmental effects could be used as checklists for future development of more sustainable collaborative consumption offers. Originality/value This paper makes a unique contribution to the concept of CFC. To the knowledge of the authors, this is the first paper that has been explicitly dedicated to examining different types and environmental effects of CFC.

This paper proposes that Green HRM can meet its full potential only by considering employees in their twofold role as producers and consumers. Employees learn different kinds of behaviour not exclusively at the workplace, but also in private life. Since reciprocal interactions between working life and private life occur, a "green work-life balance concept" is suggested to facilitate environmentally friendly behaviour in both life domains. The concept offers chances not only for the environment, but also for the company and its employees by increasing, for example, work motivation and job retention. However, challenges like employees' reactance to allow corporate influence on private life need to be addressed. Green Work-Life-Balance: Eine neue Perspektive für umweltorientiertes Personalmanagement Dieser Beitrag geht davon aus, dass umweltorientiertes Personalmanagement (Green HRM) dann besonders wirkungsvoll sein kann, wenn es die Mitarbeiter in ihrer Doppelrolle als Produzenten und Konsumenten berücksichtigt. Mitarbeiter lernen unterschiedliche Verhaltensweisen nicht nur am Arbeitsplatz, sondern auch im Privatleben. Da Wechselwirkungen zwischen Arbeitsleben und Privatleben unvermeidlich sind, kann das Konzept einer "grünen Work-Life-Balance" umweltfreundliches Verhalten in beiden Lebensbereichen fördern. Positive Effekte für die Umwelt, für Unternehmen und Mitarbeiter sind denkbar, indem zum Beispiel Arbeitsmotivation und Mitarbeiterbindung verbessert werden. Doch auch mögliche Risiken müssen bedacht werden, wie beispielsweise die Reaktanz der Mitarbeiter gegenüber einem Eingriff des Arbeitgebers in ihr Privatleben.
