Exhibit: Shift in Aggregate Demand In this graph, initially the economy is at point E,withpriceP0 and output P Aggregate demand is given by curve AD0, an short-run aggregate supply (SRAS) and long-run aggregate supply (LRAS) represent, respectively, short-run and long-run aggregate supply. Now assume that the aggregate demand curve shifts so that it is represented by AD1. The economy mov first to point and then, in the long run, to point A; D D; A C; B B; C
