Construct an Aggregate Supply and Aggregate Demand model where AS and AD are in equilibrium at potential GDP at a price level of $110$ and Real GDP of $$13\mathrm{.}0$ trillion dollars. Be sure to label all parts of the graph.

a$.$ Graph the initial effects of a recession that causes AD to decrease and real GDP to fall $$0\mathrm{.}5$ trillion.

b$.$ Explairf what will happen in the long run if nothing is done.

c$.$ If the government wanted to intervene in the economy, explain the Fiscal Policy measures that can be used to bring real GDP back to potential.

d$.$ Assume the Government multiplier is $1\mathrm{.}25$ and Potential GDP has grown to $$14$ trillion dollars. What amount of discretionary fiscal policy is needed to restore real GDP to potential GDP$?$

e$.$ Graphically show the government's fiscal policy action and explain the outcome.
