Question
Assume that the potential GDP of the economy of Arion is 1,200 96 .b. If firms become more optimistic and aggregate demand increases by .
Solution
a. The equilibrium real GDP is where the aggregate quantity demanded equals the aggregate quantity supplied. Looking at the table, this occurs when the price index is 100 and the GDP is 1,120 and the price level is 100. Since the potential GDP is also 0.
b. If firms become more optimistic and aggregate demand increases by $40, the aggregate demand 2 column would be as follows:
Aggregate Quantity Demanded 2 $1,240 1,220 1,200 1,180 1,160 1,140 1,120 1,100 1,080 1,060 1,040
c. With the increase in aggregate demand, the new equilibrium real GDP and price level is where the new aggregate quantity demanded equals the aggregate quantity supplied. This occurs when the price index is 101 and the GDP is 1,140 and the price level is now 101.
d. Now, since the potential GDP is 1,140, there is an inflationary gap. The gap is equal to $20.

The following table shows the aggregate demand and aggregate supply schedule for a hypothetical economy. Real domestic output demanded (in billions) Price level Real domestic output supplied (in billions)$500 350 $3000$1000 300 $3000$1500 250 $2500$2000 200 $2000$2500 150 $1500$3000 150 $1000Refer to the above table. If the quantity of real domestic output demanded decreased by $500 and the quantity of real domestic output supplied increased by $500 at each price level, the new equilibrium price level and quantity of real domestic output would be:
