The purpose of this study is to investigate how social media and user-generated content (UGC) foster consumer engagement through the development of a good city image. Special emphasis is placed on the attitudes of potential visitors, how these attitudes affect a city’s image, and the perceived social distance between users and the authors of social media content. The study adopts a 2 x 2 experimental design in which high/low green image and high/low social distance are examined. The results suggest that a green city image has a significant effect on potential visitors’ attitude towards cities. Moreover, this study found that the effects of social media content varies according to the perceived social distance between the author of the post and potential visitors.

The market for environmentally friendly or ‘green’ products has increased substantially over the last ten years (Willer and Kilcher, 2010). Both brand manufacturers and retailers are increasingly, and successfully, incorporating environmental and social issues in their brands (Aouina Mejri and Bhatli, 2014; Chkanikova and Lehner, in press; Gleim et al., 2013). Given the increasing importance of ‘green’ branding, the current study examines the role of key drivers (i.e., brand equity, store image and product familiarity) in the consumption of green brands. Moreover, since previous studies found that positive evaluations of a specific brand led to more positive buying behavior for the green product concept in general (Bartels and Hoogendam, 2011), in the current study we also assess the impact of these key drivers on green consumption in general. Finally, by explicitly distinguishing between store brands and national brands, we try to determine whether these relationships differ between these two types of brands in a green context. To test these effects, we used a panel study among consumers in Australia, Canada, Germany, the Netherlands, and the U.S.. For each country, we used one national brand and one or two store brands. Respondents randomly received one of these brands to evaluate. This process resulted in 404 respondents for store brands and 302 respondents for national brands. Results show that store image and brand equity have a direct effect on the consumption of green store brands and green national brands. In addition, we found that for both store and national brands, the relationship between brand equity and green brand consumption is partially mediated by the perceived image of the store where that brand is sold. Furthermore, for national brands, a positive store image also leads to an increase in green consumption behavior in general, which is not the case for store brands. Finally, for national brands, there is a clear relationship between product familiarity and brand consumption, whereas this is not the case for store brands.

Next to brand manufacturers, retailers are increasingly incorporating ‘green’ issues in their store brands. Although a lot of studies are devoted to comparing store brands with national brands (e.g., Steenkamp et al., 2010), there is limited research that compares these two types of brands in a ‘green’ context. This study investigated what factors influence the consumption of ‘green’ store brands and national brands by focusing on three important determinants: brand equity, store image and brand identification.Different models are tested in which we incorporate both mediating and moderating effects of these constructs on green brand consumption. Using the context of organic food brands, we conducted a longitudinal online panel study among consumers in Australia, Canada, Germany, the Netherlands, the UK and the US. Participants completed a self-administered questionnaire and, for each country, received either a questionnaire on store brands (n = 562) or on national brands (n = 302). Multiple regression analyses showed that for store brands, brand equity and brand identification had a positive direct effect on brand consumption. Additional analyses indicated that brand equity was not mediated by store image, but that store image moderated the effect of brand equity on brand consumption. For national brands, store image and brand identification had a positive direct effect on brand consumption. Mediation analysis showed partial mediation of brand equity by store image. We did not find a moderating effect of brand equity on brand consumption for national brands.Our findings indicate that for ‘green’ store brands, the relationship between brand equity and consumption is strengthened by consumers’ image of the store. In contrast, for national brands, the relationship between consumers’ brand equity and brand consumption is not strengthened but actually partially determined by the current image of the store where that brand is sold. In addition, identification with the green brand seems to play an important role in brand consumption for both store brands and national brands.
