PurposeThe purpose of this paper is to examine the relationships between product‐ and store‐related attributes of eco‐fashion and fashion consumers’ eco‐fashion consumption decisions; and if such relationships are subject to the price premium level of eco‐fashion.Design/methodology/approachA survey was conducted with consumers in Hong Kong: in total, 216 consumers participated in the survey. A confirmatory factor analysis was conducted to check the validity and reliability of the scales. Hypotheses were tested using multiple regression analysis.FindingsThe findings showed that only store‐related attributes of eco‐fashion positively influence consumers’ eco‐fashion consumption decision, yet, such relationship can be weakened by the price premium level of eco‐fashion.Research limitations/implicationsFashion consumers’ response to product‐ and store‐related attributes of eco‐fashion is still important in predicting fashion consumers’ eco‐fashion consumption decision. Fashion consumer environmental attitudes can predict fashion consumers’ eco‐fashion consumption decision better than fashion consumers’ attitude towards eco‐fashion.Practical implicationsIt is not enough for fashion companies to manufacture fashion clothing in an ethical production system and develop and design fashion clothing with sustainable and recyclable materials. They must also improve store‐related attributes of eco‐fashion to better satisfy fashion consumer needs, and should be cautious in the direct and moderating effect of price premium level of eco‐fashion when determining the price premium level of eco‐fashion.Originality/valueThe paper contributes to research by advancing understanding on how consumers make ethical consumption decisions in purchasing fashion, and provides retailers with managerial insights into devising marketing plans to promote eco‐fashion consumption, which facilitate fashion companies’ development of a sustainable fashion supply chain. Limitations and directions for future research are also presented in the paper.

Facing the growing concern of environmental impact, green service (GS) has emerged as an important research topic in production and operations management. However, empirical research on GS is hindered by the lack of theoretically developed and empirically validated measurement scales covering various practices in service operations of a supply chain. GS indicates the strategic orientation of firms in developing a combination of practices and routines to reduce environmental impact in service operations that span from product development to servicing customers. Grounded in the natural resource‐based view (NRBV), this study conceptualizes GS from the supply chain perspective and in the consumer‐product context to develop a GS measurement model. Collecting secondary and primary data in both qualitative and quantitative forms, this study reports the development of GS multi‐item measurement scales using a multi‐method research design that combines interviews, content analysis, and mass survey. GS is operationalized as a multi‐dimensional construct reflecting three complementary dimensions, namely pollution prevention‐, product‐, and long‐term development‐oriented GS practices, where each of them comprises three sub‐dimensions, resulting in a total of 34 measurement items. The empirically validated scales can be used to advance theory and practices of GS, while providing a useful reference for firms to evaluate their GS efforts, and identify areas for improvement.

It has been previously reported that a higher erythropoiesis stimulating agent (ESA) dose in hemodialysis patients is associated with adverse outcomes including mortality; however the causal relationship between ESA and mortality is still hotly debated. We hypothesize ESA dose indeed exhibits a direct linear relationship with mortality in models of association implementing the use of a marginal structural model (MSM), which controls for time-varying confounding and examines causality in the ESA dose-mortality relationship. We conducted a retrospective cohort study of 128 598 adult hemodialysis patients over a 5-year follow-up period to evaluate the association between weekly ESA (epoetin-α) dose and mortality risk. A MSM was used to account for baseline and time-varying covariates especially laboratory measures including hemoglobin level and markers of malnutrition-inflammation status. There was a dose-dependent positive association between weekly epoetin-α doses ≥18 000 U/week and mortality risk. Compared to ESA dose of <6 000 U/week, adjusted odds ratios (95% confidence interval) were 1.02 (0.94–1.10), 1.08 (1.00–1.18), 1.17 (1.06–1.28), 1.27 (1.15–1.41), and 1.52 (1.37–1.69) for ESA dose of 6 000 to <12 000, 12 000 to <18 000, 18 000 to <24 000, 24 000 to <30 000, and ≥30 000 U/week, respectively. High ESA dose may be causally associated with excessive mortality, which is supportive of guidelines which advocate for conservative management of ESA dosing regimen in hemodialysis patients.
