DEMAND ELASTICITY AND TOTAL EXPENDITURE: The notion that price-induced changes in total expenditure for a good (price times quantity) depends on the relative price elasticity of demand. In particular, for relatively elastic demand (1 < E < ∞) changes in price cause total expenditure to change in the opposite direction. An increase in price causes total expenditure to fall and a decrease in price causes total expenditure to rise. For relatively inelastic demand (0 < E < 1) changes in price cause total expenditure to change in the same direction. An increase in price causes total expenditure to rise and a decrease in price causes total expenditure to fall. For unit elastic demand (E =1) price changes do not cause any change in total expenditure. Total expenditure is the same whether price increases or decreases.

SAVING The after-tax disposable income of the household sector that is not used for consumption expenditures. Saving primarily involves the use of income to purchase legal claims through financial markets rather than the direct purchase of physical goods and services (which is consumption expenditures). In the circular flow model, saving is the diversion of household income away from consumption expenditures and into the financial markets, which then flows to business investment expenditures and government purchases. Saving is one of two basic uses of disposable income. The other is consumption expenditures.
