This study investigates the impact of social media influencers and word of mouth on purchasing decisions, and brand awareness is a mediator variable in the relationship. Data were obtained from 244 respondents in Indonesia who were selected by using purposive sampling techniques. Structural Equation Modeling with AMOS 26 software was employed for data analysis. The findings revealed that word of mouth and the use of social media influencers as one of the social media marketing platforms affect purchase decisions. The indirect relationship between social media influencers through brand awareness is also very effective in increasing purchase decisions. The findings contribute to the literature by showing that the prevalence of social media influencers and word of mouth positively affect the purchasing decisions made by Indonesians regarding cosmetic items manufactured by Secondate. In addition, there is a significant effect of brand awareness on purchase decisions illustrating how consumers' impressions of a brand shape their perceptions of the confidence and security of using Secondate cosmetics.

This study investigated the impact of growing psychological biases on investment satisfaction. Three psychological biases are examined: overconfidence, disposition effect, and representative. The effect of these behavioral characteristics on investment satisfaction was analyzed using financial knowledge as a moderator. This study investigated four econometric equations to describe the moderator function of financial knowledge. The interaction impact was examined using regression with a moderating variable. The analysis results indicated that overconfidence and representational bias significantly influenced investment satisfaction. Meanwhile, the disposition effect had a non-significant positive effect. Financial knowledge literacy cannot minimize these psychological biases, but it can operate as a moderating variable, as indicated by the interaction model (homologiser moderation).
