摘要

我们回顾了最近关于理性注意力不集中的文献，确定了主要的理论机制，并解释了它如何帮助我们理解经济学领域的各种现象。理性不注意理论假设代理不能处理所有可用的信息，但他们可以选择关注哪一部分信息。经济学中几个重要的结果都是建立在不完全信息基础之上的。如今，由于新技术的出现，信息的形式比以往任何时候都要多，但我们能够消化的却很少。因此，我们拥有何种形式的不完全信息并据此采取行动，很大程度上取决于我们选择关注何种信息。这些选择是由当前的经济状况所驱动的，并且隐含着许多经验支持的偏离标准模型的行为。将这些关于人类局限性的见解与新古典经济学的优化方法相结合，产生了一个新的、普遍适用的模型。(凝胶d83, d91, e71)

Rational Inattention: A Review

We review the recent literature on rational inattention, identify the main theoretical mechanisms, and explain how it helps us understand a variety of phenomena across fields of economics. The theory of rational inattention assumes that agents cannot process all available information, but they can choose which exact pieces of information to attend to. Several important results in economics have been built around imperfect information. Nowadays, many more forms of information than ever before are available due to new technologies, and yet we are able to digest little of it. Which form of imperfect information we possess and act upon is thus largely determined by which information we choose to pay attention to. These choices are driven by current economic conditions and imply behavior that features numerous empirically supported departures from standard models. Combining these insights about human limitations with the optimizing approach of neoclassical economics yields a new, generally applicable model. (JEL D83, D91, E71)

期刊介绍： Commencing in 1969, the Journal of Economic Literature (JEL) serves as a vital resource for economists, offering a means to stay informed about the extensive literature in the field. Each JEL issue features commissioned, peer-reviewed survey and review articles, book reviews, an annotated bibliography categorizing new books by subject, and an annual index of dissertations from North American universities.
