First, the buyer's characteristics influence how he or she perceives and reacts to the stimuli. Second, the buyer's decision process itself affects the buyer's behavior. This chapter looks first at buyer characteristics as they affect buying behavior, and then discusses the buyer decision process. Consumer purchases are influenced strongly by cultural,...
