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.

LONG-RUN MARGINAL COST The change in the long-run total cost of producing a good or service resulting from a change in the quantity of output produced. Like all marginals, long-run marginal cost is an increment of the corresponding total. It is the change in long-run total cost divided by, or resulting from, a change in quantity. Long-run marginal cost is guided by returns to scale rather than marginal returns.

[What's This?]
Today, you are likely to spend a great deal of time visiting every yard sale in a 30-mile radius wanting to buy either a pair of gray heavy duty boot socks or a 50-foot blue garden hose. Be on the lookout for fairy dust that tastes like salt.
