The Role of Behavioral Economics in Modern Financial Decision-Making: A Comprehensive Review

Behavioral economics has emerged as a pivotal field that challenges traditional economic theory by incorporating psychological, social, and cognitive influences into financial decision-making. As global financial markets become increasingly complex, understanding how individuals and institutions actually behave—rather than how they are assumed to behave—has become essential for predicting market outcomes, designing public policy, and improving financial products. This article offers a comprehensive review of behavioral economics, examining its theoretical foundations, key biases, applications in financial markets, implications for consumer behavior, and influence on regulatory frameworks. The review highlights that behavioral insights offer powerful tools for addressing market inefficiencies, enhancing financial well-being, and informing more effective economic policy. However, it also identifies limitations and ethical challenges that must be addressed to ensure responsible use of behavioral interventions. Overall, behavioral economics provides crucial insights into the human factors shaping modern finance.
