经济理论该如何回应行为'异象'挑战——来自桑塔费学派的看法

摘要

The study of behavioral economics is not trying to challenge the rational actor model(also called BPC model)of mainstream economics(BPC model), but to revise and improve the BPC model.Many inconsistent preferences and"irrational"behavior could get reasonable explanations, as long as their situations are considered.The correct response of economic theory to the anomalies challenge of human behavior is not to abandon the BPC model, but to modify and improve the BPC model with the situation -dependent -preferences and evolutionary psychological propensity considered.%行为经济学研究不是要挑战主流经济学的理性行动者模型(BPC模型),而是要改造和完善BPC模型.许多不一致的偏好和"非理性"的行为,只要加入情景因素便可得到合理的解释.经济理论对人类行为"异象"挑战的正确回应,不是抛弃BPC模型,而是考虑偏好的情景依存性和进化心理机制对BPC模型进行修正和改造.
