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.

SHORT RUN, MICROECONOMICS In terms of the microeconomic analysis of production and supply, a period of time in which at least one input under the control of a firm used in the production process is variable and at least one input is fixed. In the short run, the variable input is usually labor and the fixed input is capital. The short-run analysis of production reveals the law of diminishing marginal returns and provides an understanding of the upward-sloping supply curve and the law of supply. This is one of four production time periods used in the study of microeconomics. The other three are long run, very long run, and very short run (or market period). The short run is also a time period designation used in the macroeconomic analysis of business cycles.
