Behavioral economics is a field of study that combines insights from psychology and economics to understand how individuals make decisions. It focuses on understanding the cognitive, emotional, and social factors that influence decision-making, often deviating from traditional economic assumptions of rationality and self-interest. Researchers in behavioral economics study topics such as biases, heuristics, and social norms that affect individuals' choices and behaviors. The field seeks to improve economic models and policies by incorporating a more realistic understanding of human behavior. Behavioral economics has applications in various areas such as finance, marketing, public policy, and health behavior.
