An Approach to Incorporating Psychology into Economics
提出一种在保持经济学传统技术和目标（形式化理论、实证分析、预测）的同时，增强其心理学现实性的方法，通过开发可移植的模型扩展来实现。
This article proposes an approach to improving the psychological realism of economics while maintaining its conventional techniques and goals--formal theoretical and empirical analysis using tractable models, with a focus on prediction and estimation. Besides tolerating the imperfections that come with precision, models should aim for two crucial criteria: power and scope. The approach advocated is to develop portable extensions of existing models that embed preexisting theories as parameter values, while introducing the new psychological assumptions as alternative parameter values, and make the model portable by defining it in all cases where existing models make predictions.
