CHANGE IN AGGREGATE DEMAND: A shift of the aggregate demand curve caused by a change in one of the aggregate demand determinants. In essence, a change in aggregate demand is caused by any factor affecting aggregate demand EXCEPT the price level. This concept should be contrasted directly with a change in aggregate expenditures. You might also want to review the terms change in quantity demanded and change in demand, as well. The change in aggregate demand is comparable to the change in market demand. A change in aggregate demand is a change in ALL price level-aggregate expenditure combinations, meaning that each price level is matched up with a different aggregate expenditure (which is illustrated as a shift of the aggregate demand curve). This change in aggregate demand is caused by a change in any of the aggregate demand determinants. In contrast, a change in aggregate expenditures is a change from one price level-aggregate expenditure combination to the another (which is illustrated as a movement along a given aggregate demand curve).

ADVERSE SELECTION An inefficient, bad, or adverse outcome of a market exchange that results because buyers and/or sellers make decisions based on asymmetric information. This commonly results in a market that exchanges a lesser quality good, what is termed the market for lemons. Two related problems resulting from asymmetric information are moral hazard and the principal-agent problem. Two methods of lessoning the problem of adverse selection are signalling and screening.
