AGGREGATE DEMAND DETERMINANTS: An assortment of ceteris paribus factors that affect aggregate demand, but which are assumed constant when the aggregate demand curve is constructed. Changes in any of the aggregate demand determinants cause the aggregate demand curve to shift. While a wide variety of specific ceteris paribus factors can cause the aggregate demand curve to shift, it's usually most convenient to group them into the four, broad expenditure categories -- consumption, investment, government purchases, and net exports. The reason is that changes in these expenditures are the direct cause of shifts in the aggregate demand curve. If any determinant affects aggregate demand it MUST affect one of these four expenditures.

DEMAND ELASTICITY AND TOTAL EXPENDITURE The notion that price-induced changes in total expenditure (price times quantity) depend on the relative price elasticity of demand. If demand is relatively elastic, then changes in price cause total expenditure to change in the opposite direction. If demand is relatively inelastic, then changes in price cause total expenditure to change in the same direction. If demand is unit elastic, then changes in price do not cause any change in total expenditure.

[What's This?]
Today, you are likely to spend a great deal of time at a going out of business sale wanting to buy either a genuine down-filled pillow or one of those "hang in there" kitty cat posters. Be on the lookout for rusty deck screws.
