Understanding consumer behavior is crucial for a firm's long-term success, emphasizing the importance of catering to the needs and wants of the target market. Consumer decision-making varies in type, ranging from extensive problem solving, where no criteria are established, to routinized response behavior, where consumers rely on past experiences. Additionally, decision-making views include economic, passive, cognitive, and emotional perspectives, which influence pre-purchase information gathering and post-purchase experiences, including potential dissonance and satisfaction.
