“…However, the dependent variables of the aforementioned research are consumer attitudes and WoM without explicitly testing the PI. Several studies tested PI ( n = 14, 26.9%), such as perceived brand CSR awareness (Olšanová et al, 2022), perceived value and functionality (Aliyev et al, 2019; Sugimoto & Nagasawa, 2017; Talukdar & Yu, 2020), and perceived pride and novelty (Adıgüzel & Donato, 2021). Insight can be gained from these studies that explicitly evaluated sustainable luxury goods and consumer PI: Continuing the consistency of sustainable goods with the original brand tone of voice (e.g., keeping the design consistent with the original product line rather than designing it to look like a green product) and reducing the perceived value and perceived functionality of consumers can achieve moral satisfaction and novelty experiences for consumers and promote PI (Amatulli et al, 2018; De Angelis et al, 2017; Platania et al, 2019; Sugimoto & Nagasawa, 2017).…”
