卡内曼的主要贡献在于对人类在不确定性条件下的判断与决策行为的研究。一方面,他与特韦尔斯凯证明了人类的实际决策是如何系统性地偏离主流经济理论的逻辑预测的,有助于后来学者建立相关模型。另一方面,他们提出的期望理论对观察到的行为提供了合理的解释,构成了这个领域许多应用经验工作的基础,使行为经济学、行为金融学的规范研究成为可能。 Carney’s main contribution lies in the study of human judgment and decision-making under uncertainty. On the one hand, he and Tverskay prove how the actual human decision-making systematically deviates from the logic predictions of mainstream economic theory and help later scholars to establish related models. On the other hand, their expectations theory provides a reasonable explanation of the observed behavior and forms the basis of many applications and experience work in this field, making it possible to conduct a normative study of behavioral economics and behavioral finance.
