The Development of Distinct Choice Process Segments Over Time: A Stochastic Modeling Approach
摘要
This paper examines Howard’s (Marketing Management: Analysis and Planning, Homewood, IL: Richard D. Irwin, 1963) typology dividing decision making into extensive problem solving (ESP), limited problem solving (LSP), and routinized response behavior (RRB). Specifically, the amount of information accessed in a longitudinal experiment is studied. Information acquisition is modeled stochastically at the individual level, and the existence of two segments (LSP and RRB) is tested in a nested-model framework.
