Habits as adaptations: An experimental study
通过实验室实验，研究人们在习惯形成和线索选择中的精明程度，发现只有当自身过去行为这一线索有用时，它才会影响行为，表明习惯建模需谨慎，但信息获取存在短视。
When observable cues correlate with optimal choices, habit-driven behavior can alleviate cognition costs. We experimentally study the degree of sophistication in habit formation and cue selection. To this end, we compare lab treatments that differ in the information provided to subjects, holding fixed the serial correlation of optimal actions. We find that a particular cue – own past action – affects behavior only in treatments in which this habit is useful. The result suggests that caution is warranted when modeling habits via a fixed non-separable utility. Despite this sophistication, lab behavior also reveals myopia in information acquisition.
