Abstract

This study aims to analyze the phenomenon of mental accounting bias and its implications for individual financial behavior through a systematic literature review (SLR) approach. A total of nine Scopus-indexed articles were reviewed to identify how mental accounting influences financial decisions in contexts such as investment, consumption, and personal money management. The results reveal that mental accounting bias significantly affects non-rational decision-making by leading individuals to categorize money into separate mental accounts that shape perceptions of risk, gain, and loss. In investment decisions, mental accounting causes investors to divide their portfolios based on emotional preferences rather than economic efficiency, while in consumption behavior, the house-money effect encourages higher spending of windfall income. Furthermore, the use of digital technologies such as smartphone applications has been found effective in mitigating this bias by increasing transaction salience and financial awareness. Theoretically, this research reinforces Prospect Theory (Kahneman & Tversky, 1979) and Financial Behavior Theory (Shefrin & Statman, 2000), emphasizing that financial decisions are influenced not only by rational factors but also by psychological and emotional processes. Practically, the study highlights the importance of behavioral financial literacy and technology utilization in reducing cognitive bias and promoting wiser financial management.

Abstract

The rapid growth of financial technology (fintech) has expanded financial inclusion while simultaneously increasing behavioral risks in investment decision-making, particularly among young investors. This study examines the effect of behavioral biases—overconfidence bias, herding bias, and mental accounting—on investment decisions of young investors in Sorong City, and investigates the moderating role of financial literacy while considering gender differences. Using a quantitative approach, data were collected from 216 respondents aged 19–34 years through structured questionnaires and analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM). The results reveal that overconfidence bias and mental accounting have a positive and significant effect on investment decisions for both male and female investors, while herding bias significantly influences investment decisions only among male investors. Furthermore, financial literacy does not moderate the relationship between behavioral biases and investment decisions across genders. These findings indicate that higher financial literacy does not necessarily mitigate behavioral biases in a fintech-driven investment environment. This study contributes to behavioral finance literature by providing empirical evidence from a developing country context and offers practical implications for policymakers and fintech providers in designing more effective financial education programs and investor protection mechanisms targeting young investors.
