An increase in demand is represented by a shift of the demand curve to the right: A decrease in from ECON 101 at Universitat Pompeu Fabra
One of several specific aggregate demand determinants assumed constant when the aggregate demand curve is constructed, and that shifts the aggregate demand curve when it changes. An increase in the inflationary expectations causes an increase (rightward shift) of the aggregate curve. A decrease in the inflationary expectations causes a decrease (leftward shift) of the aggregate curve. Other notable aggregate demand determinants include interest rates, federal deficit, and the money supply.
