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.

AGGREGATE EXPENDITURES DETERMINANTS Ceteris paribus factors, other than aggregate income or production, that are held constant when the aggregate expenditures line is constructed and which cause the aggregate expenditures line to shift when they change. Some of the more important aggregate expenditures determinants are interest rates, expectations, fiscal policy, wealth, and exchange rates.
