Practical implications suggest enhancing workplace facilities, strengthening internal communication, and increasing job satisfaction through career development and welfare programs. Future research should broaden the scope to other organizational units and include additional internal and external factors such as digital competence, intrinsic motivation, and leadership style to gain deeper insights into performance determinants
Brand-Driven Economic Behavior: Analyzing the Impact of Brand Consciousness and Perceived Value on Luxury Beauty Purchases at Sephora
Get PDFThis study investigates the influence of terminal values, instrumental values, and brand consciousness on the behavioral intentions of Generation Z consumers in Indonesia toward purchasing luxury beauty products at Sephora. The research is grounded in Self-Completion Theory and adapts a conceptual framework from Kautish et al. (2020). Using a quantitative approach with data collected from 296 respondents, this study employed Partial Least Squares Structural Equation Modeling (PLS-SEM) to test the hypotheses. The findings indicate that both terminal and instrumental values significantly affect brand consciousness. Moreover, brand consciousness strongly influences behavioral intention and also mediates the relationship between values and purchase intentions. The results emphasize that Gen Z’s consumption behavior in the luxury beauty sector is not only driven by product functionality and prestige, but also by deeper psychological needs such as self-expression and value alignment. These insights offer strategic implications for marketers aiming to create emotionally resonant and value-driven brand experiences in emerging markets like Indonesi
The Impact of Free Strategy and Delivery Speed on Consumer Satisfaction with the Level of Ease of Product Return as a Moderation Variable on Shopee Marketplace Users in DKI Jakarta
Get PDFThis study aims to analyze the influence of free shipping strategy and delivery speed on consumer satisfaction with the level of ease of product returns as a moderation variable for Shopee marketplace users in DKI Jakarta. The approach used is through a quantitative approach and the Partial Least Square (PLS) method, data was collected from 153 respondents. The results of the study show that free shipping, delivery speed, and ease of product returns have a positive and significant effect on consumer satisfaction. However, the variable of ease of return of products actually weakens the relationship between free shipping and satisfaction, and does not moderate the relationship between delivery speed and consumer satisfaction significantly. These findings emphasize the importance of aligning promotional strategies and after-sales service in improving consumer satisfaction in the e-commerce sector. This research makes a practical contribution for marketplace managers in designing services that are more responsive to customer needs
