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.

ELASTICITY AND DEMAND SLOPE The slope of a straight-line demand curve, one with a constant slope, has constantly changing elasticity. It includes all five elasticity alternatives--perfectly elastic, relatively elastic, unit elastic, relatively inelastic, and perfectly inelastic. No two points on a straight-line demand curve have the same elasticity.
