Rational Inattention

Authors:
Abstract: The idea of rational inattention is that individuals have a limited amount of attention and therefore have to decide how to allocate their attention. There is a vast amount of information that is, in principle, available to decision-makers (e.g. information published in books, magazines, newspapers, and scientific articles; information available on the Internet; knowledge available through colleagues, friends and family), but due to limited attention it is simply impossible to attend to all of this information. Therefore decision-makers have to choose which information to attend to carefully, which information to attend to less carefully, and which information to ignore. According to the theory of rational inattention, decision-makers take this decision optimally. The literature on rational inattention argues that the optimal allocation of attention by decision-makers can explain important features of economic data.
