Explain the income determination through the Aggregate Demand and Aggregate Supply approach.


● The equilibrium level of income is the point where the aggregate demand and aggregate supply are equal and will remain constant.


● If there is any diversion from this equilibrium level, the economic forces will work in a manner so that the original position is attained = AD=AS.


● This can be explained with the following diagram:



● In the above diagram, X and Y-axis represent the national income and aggregate demand.


● At point O, income = consumption. this is called breakeven point.


● The equilibrium of national income is at point E, where AD=AS.


● Let us assume that AD>AS, at Y2 and we have diverted from the original position.


● The production will have to be increased to cover up the excess demand.


● This will increase the national income, which in turn increases the consumption.


● This will continue until the AD = AS.


● Now, let us assume that again we have diverted from the original position and now AS>AS.


● There would be an unsold stock of goods piled up with the producers.


● The producer will reduce his production.


● The national income will fall and consequently, the consumption falls as well.


● This will continue till the AS=AD.
