AGGREGATE DEMAND DETERMINANT: A ceteris paribus factor that affects aggregate demand, but which is 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.

HOTELLING'S RULE: The notion that efficiency and competitive market forces will lead to an increase of scarcity rent of a finite, exhaustible resource that is equal to the interest rate. The logic behind Hotelling's Rule is that as a finite fossil fuel is depleted, less is available in the future, causing scarcity rent, and thus the resource price, to increase. An increase in the resource price reduces the quantity demanded and conserves more for future consumption. When finite, exhaustible resource markets are competitive, this process generates an efficient allocation over time.

AGGREGATE DEMAND SHIFTS Changes in the aggregate demand determinants cause the aggregate demand curve to shift. The mechanism is comparable to that for market demand determinants and market demand. There are two alternatives--an increase in aggregate demand and a decrease in aggregate demand. An increase in spending by any of the four sectors--household, business, government, and foreign--shifts the aggregate demand curve to right. A decrease in spending by these four sectors shifts the aggregate demand curve to left.

Today, you are likely to spend a great deal of time waiting for visits from door-to-door solicitors wanting to buy either a wall poster commemorating next Thursday or a pair of gray heavy duty boot socks.
