Income Effect

AAA

DEFINITION of 'Income Effect'

In the context of economic theory, the income effect is the change in an individual's or economy's income and how that change will impact the quantity demanded of a good or service. The relationship between income and the quantity demanded is a positive one, as income increases, so does the quantity of goods and services demanded.

INVESTOPEDIA EXPLAINS 'Income Effect'

For example, when an individual's income increases, other things remaining the same, that person will demand more goods and services; thus increasing their consumption. The degree to which a person or economy will spend more of their income on consumption is called the marginal propensity to consume (MPC). The MPC depends on the individual's or economy's saving characteristics.
