AGGREGATE EXPENDITURE DETERMINANT: A ceteris paribus factor that affects aggregate expenditures, but which is assumed constant when the aggregate expenditure line is constructed. Changes in any of the aggregate expenditures determinants cause the aggregate expenditure line to shift. While a wide variety of specific ceteris paribus factors can cause the aggregate expenditure line 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 expenditure line. If any determinant affects aggregate expenditures it MUST affect one of these four expenditures.

This is one of two macroeconomic time designations; the other is the long run. Short-run wage and price rigidity prevents some markets, especially resource markets and most notably labor markets, from achieving equilibrium. Wage and price rigidity and the resulting resource market imbalances are the source of the positively-sloped short-run aggregate supply curve.
