Suppose that aggregate demand increases such that the amount of
real output demanded rises by $21 billion at each price
level.
Instructions: Enter your answers as whole
numbers.
a. By what percentage will the price level
increase? percent.
Will this inflation be demand-pull
inflation or will it be cost-push inflation? (Click to

b. If potential real GDP (that is, full-employment GDP) is $510
billion, what will be the size of the positive GDP gap after the
change in aggregate demand? $ billion.
c. If the government wants to use fiscal policy to counter the
resulting inflation without changing tax rates, would it increase
government spending or decrease it? (Click to
select)IncreaseDecrease.
Answer:
A]
Initially the price level is 100. Now with increase the AD,
New table is as follows -
Real Output Demanded |
Price Level |
Real Output Supplied |
515 |
118 |
515 |
523 |
109 |
512 |
531 |
100 |
510 |
539 |
90 |
507 |
547 |
82 |
500 |
The new equilibrium price level is 118.
Calculate % increase in price level -
% increase = [(118 - 100)/100] * 100
% increase = (18/100) * 100 = 18%
The price level will increase by 18 percent.
This increase in price level is due to increase in aggregate demand.
So, this inflation will be demand-pull inflation.
This inflation will be demand-pull inflation since AD has increased by $21 billion at each price.
B]
The new equilibrium real GDP is $515 billion.
Potential real GDP is $510 billion.
So,
Positive GDP gap = $515 billion - $510 billion = $5 billion
The size of positive GDP gap is $5 billion.
C]
As per the new table, real output demanded is equal to real output supplied corresponding to the price level of 118.
So,
The new equilibrium price level is 118 and the new equilibrium real GDP is $515 billion.
New equilibrium real GDP is greater than the potential real GDP.
So, there is need to decrease real GDP.
For this government should administer contractionary fiscal policy.
This involves increasing taxes or reducing government spending.
As government do not want to change tax rates, it must decrease government spending.
So, the correct answer is the Decrease.
