If aggregate demand in the long run is falling for several months in a row, it will make aggregate market results in an increase in the price level but no change in real production. The level of real production resulting from the aggregate demand shock is full-employment real production.
Aggregate demand can be described as a measurement of the total amount of demand for all finished services and goods produced in an economy. Aggregate demand is expressed as the total amount of money exchanged for those services and goods at a specific point in time and price level.
The model of aggregate demand and long-run aggregate supply predicts that the economy will eventually move toward its potential output. To see how nominal wage and price stickiness can cause real GDP to be either above or below potential in the short run, consider the response of the economy to a change in aggregate demand.
