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.

ASYMMETRIC INFORMATION Information is not equally available to everyone. Asymmetric information results because efficient information search inevitably stops short of compete information. Some people obtain more benefits from information than others, are willing to incur higher search costs, and thus end up knowing more. Or they incur lower information search costs and have easier access to the information. In a market, sellers tend to have more information about the good than buyers. Asymmetric information gives rise to adverse selection, moral hazard, and the principal-agent problem. These problems can be lessened through signalling and screening.
