Behavioral economics challenges traditional theory from "summary" of The Economic Naturalist by Robert H. Frank
Traditional economic theory assumes that individuals make rational decisions based on self-interest. This theory suggests that people carefully weigh the costs and benefits of different choices before making a decision. However, behavioral economics challenges this assumption by demonstrating that human behavior is often influenced by psychological biases and heuristics. These biases can lead individuals to make decisions that are not in their best interest, contradicting the predictions of traditional economic theory. For example, traditional economic theory cannot explain why people frequently procrastinate when faced with important tasks. According to the rational model, individuals should always prioritize tasks based on their importance and urgency. However, behavioral economics shows that procrastination is a common phenomenon because people tend to prioritize short-term pleasure over long-term goals. This behavior is not consistent with the rational decision-making framework proposed by traditional economic theory. Furthermore, traditional economic theory assumes that individuals have consistent preferences and make decisions independently of external factors. However, behavioral economics has demonstrated that people's preferences can be influenced by framing effects, social norms, and other contextual factors. For instance, individuals may be more willing to pay for a product if it is presented as a "limited-time offer" or if they see others purchasing the same product. These findings challenge the traditional economic view that individuals always make decisions based on their intrinsic preferences. In addition, traditional economic theory often fails to account for the role of emotions in decision-making. While rational models assume that individuals always make decisions based on objective information, behavioral economics shows that emotions can play a significant role in shaping choices. For example, people may be more likely to take risks when they are in a positive emotional state, even if the expected value of the decision is not favorable. This aspect of human behavior is not easily explained by traditional economic theory.- Behavioral economics has provided valuable insights into human decision-making that challenge the assumptions of traditional economic theory. By incorporating psychological factors and biases into economic analysis, behavioral economics offers a more nuanced understanding of how individuals make choices. This perspective highlights the limitations of traditional economic theory and underscores the importance of considering human behavior in economic analysis.
