ADJUSTMENT, SHORT-RUN AGGREGATE MARKET: Disequilibrium in the short-run aggregate market induces changes in the price level that restore equilibrium. If the price level is above the short-run equilibrium price level, economy-wide product market surpluses cause the price level to fall. If the price level is below the short-run equilibrium price level, economy-wide product market shortages cause the price level to rise. In both cases short-run equilibrium is restored. You might want to compare adjustment, long-run aggregate market. Price level changes induce changes in both aggregate expenditures and real production. Unlike the long-run aggregate market, changes in the price level can induce changes in short-run aggregate supply, making it greater or less than full-employment real production.

FOUR-SECTOR AGGREGATE EXPENDITURES LINE A graphical depiction of the relation between aggregate expenditures by the four macroeconomic sectors (household, business, government, and foreign) and the level of aggregate income or production. The four-sector aggregate expenditures line combines consumption expenditures, investment expenditures, government purchases, and net exports. The slope of this aggregate expenditures line is based on the marginal propensity to consume, adjusted for marginal propensities of the other expenditures that are assumed to be induced when constructing the line. This is one of three aggregate expenditures lines based on the number of sectors included. The others are the two-sector aggregate expenditures line and the three-sector aggregate expenditures line.
