Concept Introduction:

Aggregate Demand Curve ( AD ): It shows how price and the quantity demanded are related to each other. The curve is negatively slopped which means that when prices rise the quantity demanded falls.

Shift in Aggregate Demand Curve: There are several factors on which the shifting of demand curve depends. Some of them are:

  • Changes in expectation: when consumers are more confident about future then AD curve shifts in the right direction and vice versa.
  • Changes in wealth: when the wealth of individual increases means real value of assets increases then the AD curve shifts in right direction and when it decreases then it shifts leftward.
  • Size of stock of physical capital: when the size of stock is small then AD curve shifts rightward and vice versa.
  • Fiscal policy: It includes government expenditure and taxes. When government expenditure is increased or taxes are decreased then Ad curve shifts rightward and vice versa.
  • Monetary policy: It includes money supply changes. When money supply increases Ad curve shifts rightward and vice versa.

Appreciation: It is defined as the increase in the value of currencies. It leads to increase in import of goods and services. Consider value of $1 is equal to INR 60. If value of $ increases to INR 70 then dollar has appreciated

Aggregate Supply Curve ( AS ): It shows how price and the quantity supplied are related to each other. The curve is positively slopped which means that when prices rise, the quantity supplied also rises. The curve depends on the duration of time.

Short Run Aggregate Supply ( SRAS ): It is a positively slopped curve in which supply increases when price rises. The reason for upward slopping is that the wages are sticky in short run due to formal or informal contracts. At higher aggregate prices there is higher profit leading to high level of output.

Shift in Aggregate Supply Curve: There are several factors on which the shifting of demand curve depends. Some of them are:

  • Changes in nominal wages: When the nominal wage increases then the SRAS curve shifts leftward and vice versa.
  • Changes in productivity: When productivity increases due to introduction of new technology or innovation then the SRAS curve shifts rightward and vice versa.
  • Changes in commodity price: Consider the oil price to increase then in such case SRAS curve shifts leftward.
