The study advocates for a holistic understanding of financial decision-making processes, integrating insights from finance, economics, and sustainability. From a managerial perspective, the findings offer actionable insights for practitioners, emphasizing the importance of contextual factors, behavioral insights, and effective governance mechanisms in navigating the complexities of corporate finance. This research contributes to advancing knowledge in the field of corporate finance and provides guidance for practitioners, policymakers, and researchers in enhancing financial decision-making practices.
