This research aims to study the factors influencing customer retention of E-Marketplace businesses by applying the SOR theory and the mediating effect by examining the relationship between value perception, customer engagement, brand loyalty, and customer retention variables by creating a model based on the SOR theory to study the influence of environmental factors that will lead to customer retention mechanisms. The study focused on a sample group of 426 people who have used E-Marketplace services using an online questionnaire as a research tool. The model was analyzed using the CFA and the hypothesis was tested using the SEM analysis. The results showed that stimuli (S), such as customer value perception, had a strong positive influence and a crucial role in the development and creation of a mechanism for assessing individuals' internal feelings (O) on two variables, customer engagement, brand loyalty, and directly influence customer retention. Furthermore, significant evidence also showed that brand loyalty has an important role as a mediator between customer value perception and customer retention, which is the outcome factor (R) of this study. This structural model can explain customer engagement and retention up to 86.50 percent. Therefore, this research has value as a theory and guideline in formulating an operational strategy for E-Marketplace businesses.

This research aimed to study the antecedents and consequences of brand coolness for fashion clothing brands in the millennial consumer context. The data was collected through an online questionnaire on 380 consumers who used to buy brand-name fashion clothing. The data were analyzed using the structural equation model. The results showed that the antecedents of brand coolness consisted of brand experience and brand identification, both of which positively influence brand coolness. Brand coolness (i.e., reference, singular, personal, esthetic, functional, energetic, and high status) was the key driver that creates brand equity. The research results were able to explain 94% of the variance in brand coolness and 81% of the variance in brand equity. This research is empirical support that helps expand the perspective on brand coolness and presents a dimension to measure brand coolness in a more transparent and complete method. The research result also complements the marketing knowledge that can guide academics and practitioners in creating substantial brand equity in the customers' hearts.
