From an initial equilibrium in the AD-AS model, an increase in consumption growth will initially cause inflation:
and real growth to increase.
If the money supply, the velocity of money, and the price level are fixed, then increases in real GDP:
are impossible because real GDP must also be fixed.
In the basic model that includes the AD and LRAS curves only, aggregate demand shocks caused by changes in the growth of money supply:
