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.

AVERAGE PRODUCT CURVE A curve that graphically illustrates the relation between average product and the quantity of the variable input, holding all other inputs fixed. This curve indicates the per unit output at each level of the variable input. The average product curve is one of three related curves used in the analysis of the short-run production of a firm. The other two are total product curve and marginal product curve.
