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.

INJECTIONS Non-consumption expenditures on aggregate production. The three aggregate expenditures grouped under the heading of injections are investment expenditures, government purchases and exports. Injections add to the core circular flow containing consumption, production, and income. The injections-leakages model is a Keynesian economics analysis that combines injections with leakages (saving, taxes, and imports) to identify the equilibrium level of aggregate production and income.

"The victory of success is half won when one gains the habit of setting goals and achieving them. Even the most tedious chore will become endurable as you parade through each day convinced that every task, no matter how menial or boring, brings you closer to fulfilling your dreams." -- Og Mandino, Author and Speaker
