TL;DR

Decision makers often lack information or cognitive capacity, leading to dynamic search processes. The authors formulate a framework to study behavioral search using consideration sets. The framework models search as a stagewise consideration of options in a current set, characterized by behavioral postulates. The model enables identification of search paths and preferences.

Abstract

When making choices, decision makers often either lack information about alternatives or lack the cognitive capacity to analyze every alternative. To capture these situations, we formulate a framework to study behavioral search by utilizing the idea of consideration sets. Consumers engage in a dynamic search process. At each stage, they consider only those options in the current consideration set. We provide behavioral postulates that characterize this model. We illustrate how one can identify both search paths and preferences.
