Purpose – This paper aims to achieve a better understanding of the social dimension underlying green purchasing behavior by assessing the impact of environmental concern ascribed to relevant others. Design/methodology/approach – A survey was conducted among 468 French interviewees. Using a scenario, respondents were asked to choose between two similar products: one is very fashionable but harmful to the environment and the other has comparable features with a lower negative impact on the environment. In parallel, respondents had to cite four relevant others and to make several attributions about them. Environmental concern was one of these attributions. Findings – Ascribed environmental concern increases the probability to choose the product with a low environmental impact over the more harmful alternative. This process is mediated by perceived social risk and self-incongruity associated with the environmentally unfriendly product. Research limitations/implications – Conclusions are drawn on the basis of ...

To encourage sustainable consumer practices, public policy makers introduce new ecological measures, including mandatory programmes that require companies to provide environmental information about their products, even if the information is not flattering. Few academic studies consider the potential impacts of such mandatory eco-labels on consumer behaviour; the purpose of this paper is to seek to identify conditions in which a generalized eco-label in stores might modify consumers’ purchase choices

L’objectif de cet article est d’expliquer et d’illustrer la démarche méthodologique qu’il convient de suivre pour tester les effets dits de médiation modérée (effets indirects conditionnels) en marketing. Un effet de médiation modérée désigne la présence, dans un même modèle, d’une ou plusieurs variables médiatrices et d’une ou plusieurs variables modératrices. Après avoir décrit les principales approches méthodologiques permettant de tester les effets de médiation modérée en mettant l’accent sur leurs avantages et inconvénients respectifs, nous préconisons la méthode de Hayes (2013a, 2013b), que nous illustrons à travers plusieurs applications en marketing. Cette méthode permet de tester simultanément et de manière rigoureuse les effets médiateurs et les effets modérateurs. Des recommandations sont également formulées pour éclairer les chercheurs en marketing engagés dans des analyses de médiation modérée.

The purpose of this article is to explain and illustrate the methodological approach used to test moderated mediation effects (conditional indirect effects) in marketing. A moderated mediation effect indicates the presence, in a single model, of one or more mediating variables and one or more moderating variables. Having first described the main methodological approaches used to test moderated mediation effects, with an emphasis on their respective advantages and disadvantages, we go on to recommend the method used by Hayes, which we illustrate through several marketing applications. This method makes it possible rigorously and simultaneously to test both mediating and moderating effects. Recommendations are also made to guide marketing researchers in the analysis of moderated mediation.
