The paper presents a review of 128 studies on the behavior of older consumers published in the last 35 years (from 1980 to 2014) in 35 peer-reviewed journals. The purpose of the procedure is twofold: First, we aim to summarize results on age-related changes in consumer research. Second, by doing so, we evaluate the relative importance of age-related factors (chronological, biological, psychological, and social age as wells as life events and life circumstances) in research on older consumers. Results of the review show that research on older consumers is still dominated by investigations using chronological age. Influences of other aspects of the aging process, although recommended by previous research reviews and providing valuable insights, are still playing a minor role in the investigation of consumer behavior. Research with alternative age measures is still in an early, exploratory stage and future studies should include specific aspects as well as multitheoretical models of aging.
