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.

KINKED-DEMAND CURVE ANALYSIS An analysis using the kinked-demand curve to explain rigid prices often found with oligopoly. The kinked-demand curve contains two distinct segments--one for higher prices that is more elastic and one for lower prices that is less elastic. Key to this analysis is that the corresponding marginal revenue curve contains three segments--one associated with the more elastic segment, one associated with the less elastic segment, and one associated with the kink. A profit-maximizing firm can then equate marginal cost to a wide range of marginal revenue values along the vertical segment of the marginal revenue curve. This suggests that marginal cost must change significantly before an oligopolistic firm is inclined to change price.
