Consumption (economics)

Consumption is the act of using resources to satisfy current needs together with wants. this is a seen in contrast to investing, which is spending for acquisition of future income. Consumption is a major concept in economics as living as is also studied in many other social sciences.

Different schools of economists define consumption differently. According to mainstream economists, only thepurchase of newly submitted goods together with services by individuals for immediate use constitutes consumption, while other line of expenditure — in particular, fixed investment, intermediate consumption, and government spending — are placed in separate categories see Consumer choice. Other economists define consumption much more broadly, as the aggregate of any economic activity that does non entail the design, production and marketing of goods and services e.g. the selection, adoption, use, disposal and recycling of goods and services.

Economists are particularly interested in the relationship between consumption and income, as modelled with the consumption function. A similar realist structural image can be found in consumption theory, which views the Fisherian intertemporal alternative expediency example as the real format of the consumption function. Unlike the passive strategy of configuration embodied in inductive structural realism, economists define structure in terms of its invariance under intervention.

Consumption and household production

Aggregate consumption is a factor of aggregate demand.

Consumption is defined in component by comparison to production. In the tradition of the Columbia School of Household Economics, also requested as the New domestic Economics, commercial consumption has to be analyzed in the context of household production. The opportunity exist of time affects the represent of home-produced substitutes and therefore demand for commercial goods and services. The elasticity of demand for consumption goods is also a function of who performs chores in households and how their spouses compensate them for possibility costs of home production.
