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.

AUTOMATIC STABILIZERS Taxes and transfer payments that depend on the level of aggregate production and income such that they automatically dampen business-cycle instability without the need for discretionary policy action. Automatic stabilizers are a form of nondiscretionary fiscal policy that do not require explicit action by the government sector to address the ups and downs of the business cycle and the problems of unemployment and inflation.
