The demand comes from all the economic agents such as the households, firms as well as the government. The demand depends on the price level of the economy. The increase and decrease in the price level determines the level of demand in the economy. The aggregation of all the individual demands in the economy is known as the aggregate demand thus, the aggregate demand explains the relationship between the general price level and the level of real
The equilibrium is a condition where the aggregate demand curve of the economy intersects with the aggregate supply curve of the economy. Then there will be an equilibrium point derived where the economy will be in its equilibrium without any excess demand or supply. The quantity on the X axis will represent the
Concept introduction:
Aggregate demand curve: It is the curve which shows the relationship between the price level in the economy and the quantity of real GDP demanded by the economic agents such as the households, firms as well as the government.
Equilibrium: The equilibrium in the economy is the point where the economy's aggregate demand curve and the aggregate supply curve intersects with each other. There will be no excess demand or
Subpart (b):
Long run equilibrium in AD-AS model.
Subpart (b):

Explanation of Solution
When the money supply of the economy increases with the intervention of the Central Bank of the economy, the money with the public will increase. When the money with the public increases, they will feel wealthier and as a result they will demand more consumer goods and services. As a result, the aggregate demand of the economy increases and it will shift the AD curve towards the right. This can be identified as the change to the equilibrium point B as shown in Figure 1. Thus, in short, the increase in the money supply leads to the increase in the output and price level of the economy.

Aggregate demand curve: It is the curve which shows the relationship between the price level in the economy and the quantity of real GDP demanded by the economic agents such as the households, firms as well as the government.
Aggregate supply curve: In the short run, it is a curve which shows the relationship between the price level in the economy and the supply in the economy by the firms. In the long run, it shows the relationship between the price level and the level of quantity supplied by the firms.
Equilibrium: The equilibrium in the economy is the point where the economy's aggregate demand curve and the aggregate supply curve intersects with each other. There will be no excess demand or excess supply in the economy at the equilibrium.
Subpart (c):
Long run equilibrium in AD-AS model.
Subpart (c):

Explanation of Solution
When the AD curve shifts towards the right and increases the output and the price level in the short run, over time, the nominal wages, prices as well as the perceptions and expectations of the economy would adjust to the new equilibrium level. As a result of this gradual adjustment, the cost of production will increase and the result will be a leftward shift in the aggregate supply curve of the economy. Then the economy will return to its natural level of output at a higher price level of the economy. This can be identified as the movement from point B to point C in the graph shown above.

Subpart (d):
Long run equilibrium in AD-AS model.
Subpart (d):

Explanation of Solution
The sticky wages theory suggests that when there is inflation in the economy, the wage rate will adjust very slowly to the inflation. More or less the wage rates will be sticky and the main reason will be the long term contracts between the employer and the employees. Thus, in the short run equilibriums such as point A and point B, the wages of the economy would be more or less equal to each other. Whereas the point C represents the long run equilibrium and thus, the wages at the point C will be higher than that in point A and B.

Long run equilibrium in AD-AS model.
Subpart (e):

Explanation of Solution
The sticky wages theory suggests that when there is inflation in the economy, the wage rate will adjust very slowly to the inflation. More or less, the wage rates will be sticky and the main reason will be the long term contracts between the employer and the employees. So, the nominal wages at equilibrium point A and B will be same. But the increase in the general price level in the economy would reduce the real wages of the workers because, the real wage is the nominal wage divided by the price level. When the denominator increases, it will reduce the value of the real wages in the economy.

Sub part (f):
Long run equilibrium in AD-AS model.
Sub part (f):

Explanation of Solution
When the increase in the money supply happens in the economy, it will lead to the increase in the nominal wages as well as the price level in the economy in the long run. As a result of the increase in the nominal wage rate along with the price level in the economy, the real wage rate of the economy would remain unchanged. Thus, the neutrality of money applies in the long run equilibrium.
