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.

MONOPOLISTIC COMPETITION, LONG-RUN ADJUSTMENT A monopolistically competitive industry undertakes a two-part adjustment to equilibrium in the long run. One is the adjustment of each monopolistically competitive firm to the appropriate factory size that maximizes long-run profit. The other is the entry of firms into the industry or exit of firms out of the industry, to eliminate economic profit or economic loss. The end result of this long-run adjustment is two equilibrium conditions--one for profit maximization, the other for zero economic profit.
