This paper aims to examine to what extent congruity between ethical attributes (i.e. product attributes with positive implications for the environment, human rights, social issues and animal welfare) and brand concept (i.e. the unique meaning associated with a brand in consumers’ minds) influences consumers’ evaluations of brands offering ethical attributes.

Four studies involving North American consumers empirically tested the moderation effect of brand concept on consumer evaluations of ethical attributes and the mediating role of perceived congruity.

This research finds an interactive effect of ethical attribute type and brand concept on brand evaluations, such that congruent ethical attribute–brand concept pairings (i.e. a utilitarian [symbolic] ethical attribute offered by a brand with a utilitarian [symbolic] brand concept) result in more favorable brand evaluations (Studies 1, 2, 3 and 4). Consumers’ perceptions of congruity between ethical attributes and brand concepts mediate this interactive effect (Studies 2 and 3). Moreover, a positive congruity effect of ethical attributes and brand concepts emerges at higher levels of conspicuous brand consumption (Study 4).

It is important to acknowledge that the current research did not specifically consider the case of utilitarian and symbolic ethical attribute offerings by luxury brands. This is a question that is left to future investigations.

For marketing managers, findings indicate that brands gain from ethical attribute introductions only when these attributes are congruent with the brand concept. In addition, brands benefit to a greater extent from offering congruent ethical attributes when brand consumption is conspicuous.

The findings of this research contribute to the literature on the effect of ethical attributes on consumers’ responses to brands and highlight the importance of brands’ choice of ethical attributes.

This research examines the effects of physical proximity (close vs distant) of retailers’ private label brands (PLBs) relative to national brands (NBs) and brand display orientation (horizontal [brands occupy the same shelf] vs vertical [brands occupy different shelves]) on consumers’ PLB quality perceptions and PLB evaluations.

Two experiments involving real brands in different product categories tested the hypotheses.

A PLB positioned close (vs distant) to a NB is evaluated more favorably and this effect is mediated by increased PLB quality perceptions, but only in a horizontal brand display. In a vertical brand display, a PLB positioned close (vs distant) to a NB is evaluated less favorably and this effect is mediated by decreased PLB quality perceptions.

The findings suggest that to enhance consumers’ PLB quality perceptions and evaluations, PLBs be positioned next to (rather than on separate shelves) and close to (rather than distant from) NBs in the same product category.

Although the literature suggests that the best shelf position for PLBs is close to NBs, there is a lack of empirical research on the effects of relative shelf positioning on consumers’ quality perceptions and subsequent PLB evaluations. This research finds that both physical proximity and brand display orientation play an important role.

The purpose of this paper is to explore how social responsibility initiatives can be integrated into different tiers of retailers’ private label brands (PLB) and introduces a conceptual model and opposing predictions building on research in social responsibility and evolutionary psychology. The empirical evidence from two studies suggests that retailers should consider the type of PLB (i.e. quality tier) in the introduction of social responsibility initiatives.

To investigate opposing predictions, the authors conducted two experiments with presence of social responsibility initiative and PLB quality tier as the factors. The authors present the results from 168 Canadian consumers focussing on two product categories.

The findings of two experiments are more consistent with an explanation based on resource synergy beliefs rather than costly signaling theory. Social responsibility initiatives enhanced consumer evaluations of high-quality PLBs, but hurt consumer evaluations of low-tier PLBs.

Retailers should differentiate the way they accommodate social responsibility initiatives based on the type of their PLBs. Specifically, the beneficial effect of social responsibility initiative only exist for high-tier PLBs. Introducing social responsibility initiatives may hurt preference for low-tier PLBs.

This paper is the first to propose two theoretical models that address how social responsibility initiatives can affect consumer evaluations of PLBs. The initial empirical evidence is more coherent with resource synergy beliefs explanation rather than costly signaling explanation. These results suggest that social responsibility initiatives have asymmetric effects for different tiers of retailers’ PLBs.

Education is a human right and access to high quality education is key to sustainable socioeconomic development. Improving the quality of higher education institutes is essential for generating the productive human resources. Assessing the quality of higher education from the students’ perspective can be considered a crucial factor in the monitoring of service quality in universities. The purpose of this paper is to evaluate the quality of educational services in a higher education institute, the Kermanshah University of Medical Sciences (KUMS), in the west of Iran.

A multistage sampling method was used to select 346 students from the KUMS, who were enrolled in the second semester of the academic year 2015-2016. The SERVQUAL questionnaire was used to gather data on students’ perceptions and their expectations about the quality of educational services. The authors used a statistical significance level of 0.05 to examine the gap between the students’ expectations and their perceptions of service quality in five dimensions, namely tangibles, responsiveness, reliability, empathy and assurance.

The results showed that there was a negative service quality gap in all five dimensions. The overall mean score of students’ expectations and their perceptions was 3.19±0.44 and 2.4±0.45, respectively. The score gap between the overall mean score of perceptions and expectations of students was −0.79, which was statistically significant (p<0.0001). The highest and lowest quality gaps were related to the assurance (−0.84) and tangible (−0.70) dimensions, respectively.

The study indicated that the quality of educational services provided in the KUMS did not meet students’ expectations in five dimensions of service quality. Thus, it warrants further investigations to determine how to improve the quality of educational services in higher education institutes such as the KUMS.
