The ubiquity of habits and rules
探讨了在何种情况下行为主体需要依赖习惯或规则，提出七种决策情境的分类，并指出新古典经济学和行为经济学均无法完全解释这些情境中习惯与规则的基础。
Under what circumstances is it necessary or convenient for an agent to rely on habits or rules? This paper focuses on the types of decision situations giving rise to their use. Even optimization requires the deployment of rules and, for this reason, mainstream economics cannot legitimately ignore these questions. The argument is that habits and rules are ubiquitous in human activity. In a new taxonomy, seven types of decision situations are considered, classified according to the type of information problem involved. Neither neoclassical nor behavioral economics can provide a complete account of the bases of habits or rules in these cases. Copyright 1997 by Oxford University Press.
