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 VARIABLE COST Total variable cost per unit of output, found by dividing total variable cost by the quantity of output. When compared with price (per unit revenue), average variable cost (AVC) indicates whether or not a profit-maximizing firm should shut down production in the short run. Average variable cost is one of three average cost concepts important to short-run production analysis. The other two are average total cost and average fixed cost. A related concept is marginal cost.
