注意力不集中是行为经济学的一个核心和统一的主题。它渗透到微观经济学、宏观经济学、金融学、公共经济学和产业组织等不同的领域。它使我们能够以一种相当一致的方式思考行为偏差，推测它们的起源，并追踪它们对市场结果的影响。本调查首先讨论了最基本的注意力模型，使用一个相当统一的框架。然后，它讨论了用于测量注意力的方法，这些方法提出了一些挑战，尽管需要做更多的工作，但已经取得了很大的进展。然后，它检查了各种理论的注意力，行为和更多的贝叶斯。最后讨论了一些应用。例如，注意力不集中提供了一种方法来编写基本微观经济学的行为版本，如消费者理论和Arrow-Debreu。最后一节是关于注意力文献中的开放性问题，这一章是关于注意力文献的教学指南。派生是独立的。国家经济研究局工作文件系列的机构订户和发展中国家的居民可在www.nber.org免费下载这份文件。
Inattention is a central, unifying theme for much of behavioral economics. It permeates such disparate fields as microeconomics, macroeconomics, finance, public economics, and industrial organization. It enables us to think in a rather consistent way about behavioral biases, speculate about their origins, and trace out their implications for market outcomes.This survey first discusses the most basic models of attention, using a fairly unified framework. Then, it discusses the methods used to measure attention, which present a number of challenges on which a great deal of progress has been achieved, although much more work needs to be done. It then examines the various theories of attention, both behavioral and more Bayesian. It finally discusses some applications. For instance, inattention offers a way to write a behavioral version of basic microeconomics, as in consumer theory and Arrow-Debreu. A last section is devoted to open questions in the attention literature.This chapter is a pedagogical guide to the literature on attention. Derivations are self-contained.
