PurposeEnvironmental concern is getting increasing importance in consumer shopping decisions. Nevertheless, to date, sustainable packaged foods are not always the first option when consumers go shopping. This paper analyses how environmental concern moderates the role played by external factors – preference towards sustainable retailers and trust in sustainable producers – in determining consumer purchase intentions for sustainable packaged foods. Consumer involvement in eco-friendly labels, increasingly present in food packages, is investigated as indirectly impacting pro-environmental purchase intentions.Design/methodology/approachAn online survey administered to a sample of Italian food shoppers is used for the empirical analysis. A total of 278 structured questionnaires were modelled using a structural equation modelling approach.FindingsFindings show that producers and retailers' policies in favour of sustainability are key in determining consumers' sustainable purchase intentions. Further, coherent uses of labels and logos in light of sustainability can support consumer purchase decisions. Relevant is the influence played by the environmental concern in both supporting pro-environmental purchase intentions and in amplifying the trust in sustainable producers-purchase intentions path.Originality/valueThis study contributes to the literature on sustainability showing how producers and retailers may together influence consumers' pro-environmental purchase intentions. Findings extend the retail literature on the impact of producers and retailers' policies on consumers' sustainable purchases. Further, environmental concern is investigated in its moderating role on the impact of external factors on consumers' pro-environmental purchase intentions.

Purpose Literature on the motives influencing consumers’ intention to use peer-to-peer (P2P) platforms has become vast and fragmented. The purpose of this paper is to shed light on this research stream by applying a novel methodological approach that reveals the existence of alternative combinations of motives that equally boost consumers’ intention to use P2P accommodation. Design/methodology/approach The methodological approach builds on the complexity theory and includes both linear and nonlinear techniques. The empirical analysis combines multiple regression analysis and fuzzy-set qualitative comparative analysis (fsQCA). The sample comprises 458 users of a leading P2P accommodation platform. Findings The fsQCA reveals four distinct combinations of motives. Social interaction and social esteem, either combined themselves or in partial combination with economic benefits, emerge as two important drivers of behavioral intention to use P2P accommodation. Sustainability appears in three of the combinations. Originality/value This paper contributes to the P2P accommodation literature by adopting a novel methodological approach that shows the complexity behind consumers’ intention to use P2P accommodation. Consumer motives cannot be considered as separate entities because their effect on consumer intention depends on the interplay among them. Therefore, the different combinations of motives should be managed simultaneously.
