VI. Here we consider the paradox of saving one last time in the context of the AS-AD model. Suppose the economy begins with output equal to its natural level. Then there is a decrease in consumer confidence, as households attempt to increase their saving, for a given level of disposable income. a. In AS-AD and IS-LM diagrams, show the effects of the decline in consumer confidence in the short run and the medium run. Explain why curves shift in your diagrams. b. What happens to output, the interest rate, and the price level in the short run

The solution to this question can be defined as follows:

Explanation:

In point a:

When consumer interest decreases, => consumers begin and save less and more, => MPC decreases; => the "IS" curve becomes flatter; => "IS" turns inside. Currently, 'AD' shows together all the goods and financial sector, => as the 'IS' curve adjusts inside the industry, => the 'AD' would also change to the left.

In point b:

Take into account the SR models of "IS-LM" and "AD-AS." 

Therefore there is the case of a full job only at the beginning; => its optimum between "IS1" and "LM" in the "IS-LM" model; as well as the main equilibrium among "AD1" and "AS" in the "AD-AS" model "E1'," => the original equilibrium among "Y=Yf," "r=r1" and "P=P1." That now the consumer is reducing the confidence, => the 'IS' curve becomes shifting IMEI 'IS2,' => provided the 'LM' curve, that new balance is 'E2.' That's why the price in the SR is calculated, the AS will change =>, however, the AD also will shift the "AD2" side and "E2'" will become the equilibrium point in the "AD-AS" system, "r=r2 <r1" and "P=P1" throughout the new "Y=Y2 <Yf" balance.
