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 CURVE A curve that graphically represents the relation between average variable cost incurred by a firm in the short-run product of a good or service and the quantity produced. This curve is constructed to capture the relation between average variable cost and the level of output, holding other variables, like technology and resource prices, constant. The average variable cost curve is one of three average curves. The other two are average total cost curve and average fixed cost curve. A related curve is the marginal cost curve.

ORANGE REBELOON
[What's This?]
Today, you are likely to spend a great deal of time strolling through a department store trying to buy either a microwave over that won't burn your popcorn or a T-shirt commemorating the first day of winter. Be on the lookout for small children selling products door-to-door.
