In economics the term is also used to refer to management of the distribution of, and access to goods and services on the basis of needs. An example is social security and welfare services. Rather than increasing budgets for these things, governments may develop policies that allocate existing resources according a hierarchy of neediness.
It is inspired by Keynesian macroeconomics, though today elements of it are part of the economic mainstream.
The underlying idea is for the government to use tools like interest rates, taxation, and public expenditure to change key economic decisions like consumption, investment, the balance of trade, and public sector borrowing resulting in an 'evening out' of the business cycle.
Demand management was widely adopted in the 1950s to 1970s, and was for a time successful. However, it is widely regarded as a force behind the stagflation of the 1970s.
Theoretical criticisms of demand management are that it relies on a long-run Phillips Curve for which there is no evidence, and that it produces dynamic inconsistency and can therefore be non-credible.
Today, most governments relatively limit interventions in demand management to tackling short-term crises, and rely on policies like independent central banks and fiscal policy rules to prevent long-run economic disruption.
In the environmental context demand management is increasingly taken seriously to reduce the economy's throughput of scarce resources for which market pricing does not reflect true costs. Examples include metering of municipal water, and carbon taxes on gasoline.
