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).

BARRIERS TO ENTRY Institutional, government, technological, or economic restrictions on the entry of participants into a market or industry. The four primary barriers to entry are: (1) resource ownership, (2) patents and copyrights, (3) government restrictions, and (2) start-up cost. Barriers to entry are a key reason for market control and the inefficiency that results. In particular, monopoly, oligopoly, monopsony, and oligopsony often owe their market control to assorted barriers to entry. By way of contrast, perfect competition, monopolistic competition, and monopsonistic competition have few if any barriers to entry and thus little or no market control.

Fighting Business Cycles With STABILIZATION POLICIESAs you may recall, the twins, Donna the Democrat and Rhonda the Republican, seldom agree on anything involving politics, economics, fashion, or flower arrangements. Their imminent entry into the Interstate OmniBank can only mean trouble. Donna, in her official capacity as economic advisor to the President of the quaint and courteous Republic of Northwest Queoldiola, is attempting to enter Interstate OmniBank anxious to borrow enough to finance the Queoldiolan government deficit. Rhonda, as the head of the central bank of the Republic of Northwest Queoldiola, is making every effort to stop her. The source of this particular confrontation between the twins is apparently the best way to eliminate a year-long recession that has struck the quaint and courteous Republic of Northwest Queoldiola.
