Using the AS-AD and IS-LM models, show the effects of an increase in consumer confidence on the position of the AD, AS, IS, and LM curves in the short run and in the medium run. Precisely label all axes and curves to receive full credit. Label the short-run equilibrium and medium-run equilibrium with SR and MR, respectively.

hello your question has some missing information below is the missing information

Suppose the economy begins with output equal to its natural level. Then there is an increase in consumer confidence and households attempt to consume more for a given level of disposable income.

answer :

Attached below

Explanation:

IS-LM modeling curves intersects and it also defines the value of r and Y where r ( rate of interest )  Y( output level )

The AS-AD modeling is in equilibrium where aggregate demand curve and short run and long run aggregate supply curves intersects each other defining P and Y

p ( price level ) , Y ( output level )

Note : Increase in aggregate demand shifts IS outward , raises interest rate and output level
