Briefly explain whether the following statement is true or false.
In the AD-AS model, monetary policy cannot stabilize both the price level and the level of real GDP following a shock to aggregate supply.
Please answer elaborately with proper reasoning, graphs and equations. Also include a policy example.
In the AS-AD model, monetary policy cannot stablizes both the price level and the level of real GDP following a shock to aggregate supply.
The above statement is 'true' .
According to many theories of macroeconomics, a rise in the supply
of money should decrease interest rates in the economy. An increase
in the money supply means that more money is accessible for
borrowing in the economy. This growth in supply–in accordance with
the law of demand–tends to decrease the price for borrowing money.
When it is easier to obtain money, rates of consumption and lending
(and borrowing) both lean to go up.

In the long run, money is neutral: shifts in the money supply
affect only the price level in the long run.An increase in AD due
to an increase in the money supply shifts the AD curve up to the
right. Equilibrium shifts from point A to B in the short run. Costs
will eventually rise as well. So, the SRAS curve will shift up to
the left. Long-run equilibrium is always on the LRAS curve at the
economy's potential level of GDP. Changes in aggregate demand do
not have a long lasting effect on GDP, only on the price
level.
