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.

MARGINAL REVENUE PRODUCT AND FACTOR DEMAND A perfectly competitive firm's factor demand curve is that negatively-sloped portion of its marginal revenue product curve. A perfectly competitive firm maximizes profit by hiring the quantity of input that equates factor price and marginal revenue product. As such, the firm moves along its negatively-sloped marginal revenue product curve in response to changing factor prices.
