Consumer behaviour is the study of individuals, groups, or organizations and the processes they use to select, secure, use, and dispose of products, services, experiences, or ideas to satisfy their needs and wants. It is also concerned with the social and economic impacts that purchasing and consumption behaviour has on both the consumer and wider society. Consumer behaviour blends elements from psychology, sociology, social anthropology, marketing and economics, especially behavioural economics. It examines how emotions, attitudes and preferences affect buying behaviour. Characteristics of individual consumers such as demographics, personality lifestyles and behavioural variables such as usage rates, usage occasion, loyalty, brand advocacy, willingness to provide referrals, in an attempt to understand people’s wants and consumption are all investigated in formal studies of consumer behaviour. It also tries to assess influences on the consumer from groups such as family, friends, sports, reference groups, and society in general.
