. But the precise definition can vary because different schools of economists define production quite differently. According to some economists, only the final purchase of goods and services constitutes consumption, and every other commercial activity is some form of production. Other economists define consumption much more broadly, as the aggregate of all economic activity that does not entail the design, production and marketing of goods and services (e.g. "the selection, adoption, use, disposal and recycling of goods and services").

Likewise, consumption can be measured by a variety of different metric

  2. Autonomous consumption refers to consumption spending done as part of long-term plans for the future (smoothing out income fluctuations, providing for retirement and other expected future events, etc.) and as a result of habits and contractual commitments. Changes in plans, expectations, habits, etc. leads to shifts of the consumption function in a graph.


Often, as in the permanent income hypothesis

, the word "consumption" refers instead to the benefit received from consumer goods and services (as opposed to the amount spent on such products).

Sociological Studies of Consumption

Studies of consumption investigate how and why society and individuals consume goods and services, and how this affects society and human relationships. Contemporary studies focus on meanings of goods, role of consumption in identity making, and the 'consumer' society (e.g. Douglas et al). Traditionally, consumption was seen as rather unimportant compared to production, and the political and economic issues surrounding it. With the development of a consumer society, increasing consumer power in the market place, the growth in marketing, advertising, sophisticated consumers, ethical consumption etc, it is recognised as central to modern life.

 consumption. Current theories investigate the role of economic and cultural factors in constraining consumption (Bourdieu), as development of an approach that sees consumers as 'victims' of producers and their social situation. A counter theory highlights the subversive aspects of consumption, with consumers buying and using goods, places etc in ways unintended by the producers. Examples include city squares turned to skateboard parks, and music sharing on the internet.

Studies of consumption come from a variety of backgrounds. Consumer studies attempt to help marketing. User research aims to improve product design. Feminist studies highlight the importance of women as consumers, and particularly the role of the domestic arena in consumption. Media studies

Studying consumption can be done through traditional survey methods, or various ethnographic techniques. Consumption studies are difficult because they involve investigating everyday life situations, bringing research into the private domain, rather than formalised settings such as the workplace.
