2011年度诺贝尔奖经济学奖得主西姆斯近年来提出了理性疏忽理论,主要是将信息处理能力的约束纳入到经济分析之中。西姆斯认为即使信息是完全的,有限的信息处理能力也会使经济主体理性地忽略某些信息,从而信息的更新就是粘滞的。该理论用一个统一的分析框架解释经济主体的粘性选择行为,克服了传统完全理性假说的非现实性问题,在微观经济行为、宏观经济政策、经济周期等领域的研究中取得了许多重要成果,目前已成为经济学研究中迅速发展的理论体系。
Sims, winner of the 2011 Nobel Prize in economics, put forward the theory of rational negligence in recent years, mainly including the constraints of information processing capabilities into economic analysis. Sims believes that even if the information is complete, the limited ability of information processing will make economic agents ignore some of the information rationally, so the update of information is sticky. This theory uses a unified analytical framework to explain the viscous choice behavior of economic subjects and overcomes the non-realistic problems of the traditional complete rational hypothesis. Many important achievements have been made in the research of micro-economic behavior, macroeconomic policies and economic cycles, Now it has become the theoretical system of rapid development in economics research.
