What is Aggregate Demand?
Aggregate Demand is planned expenditure of all sectors at Particular Income Level
Formula of AD
We have already studied that
Aggregate Demand = Private Consumption Exp + Investment Expenditure
AD = C + I
Schedule of Aggregate Demand
It can be made by totaling Consumption and Investment Expenditure
Important Points About AD
1. Even at 0 level of Income, there is AD
due to Autonomous Consumption and Autonomous Investment Expenditure which are applicable at 0 level of income
2. AD increases with Income
With the increase in income, Consumption Investment increases but investment expenditure remains the same
Due to this increase in consumption expenditure, AD increases with income
3. Note all 3 curves do not start from Origin
Consumption Curve starts from Point S (OS Representing Autonomous Consumption Expenditure)
Investment Curve starts from Point R (OR Represents Autonomous Investment Expenditure)
AD Curve starts from Point T (OT Represents total of Autonomous Consumption and Investment Expenditure)
OT = OR + OS
4. Consumption Curve C is Positively Sloping
Increases with Increase in Income
Investment Expenditure is a horizontal line parallel to x axis
It Remains Fixed irrespective of increase in income
Aggregate Demand is combination of Consumption and Investment Curve so it is also positively sloping
