Equilibrium of Income
- Equilibrium is determined where the AD curve intersects the 45° line.
- At this point: Output = Aggregate Demand
- The 45° line represents all points where income equals expenditure.
CBSE: Class 12
Effect of an Increase in Autonomous Expenditure
- When autonomous investment rises, the AD curve shifts upward (AD₁ → AD₂).
- At the old equilibrium point E₁, AD₂ lies above the 45° line, creating excess demand.
- To clear the excess demand, firms increase output.
- A new equilibrium E₂ is established at a higher level of income.
CBSE: Class 12
Example
| Parameter | Initial | After Change |
|---|---|---|
| Autonomous Investment \[\overline{I}\] | 10 | 20 |
| Equilibrium Income (Y) | 250 | 300 |
- Consumption Function: \[C = 40 + 0.8Y\]
- Change in Investment (ΔI) = 10
- Change in Income (ΔY) = 50
CBSE: Class 12
Graphical Interpretation (Fixed Price Model)
Equilibrium Output and Aggregate Demand in the Fixed Price Model
- X-axis: Income / Output
- Y-axis: Aggregate Demand
- AD₁ shifts to AD₂ (parallel upward shift) due to an increase in autonomous investment.
- E₁ = Old equilibrium (Y = 250)
- E₂ = New equilibrium (Y = 300)
- Vertical distance between AD₁ and AD₂ = Initial increase in autonomous expenditure \[(\Delta\bar{I}=10)\].
- At the old equilibrium, E₁F measures the excess demand created by the increase in autonomous expenditure.
- Increase in output and aggregate demand is shown by E₁G = E₂G, which is greater than the initial increase in autonomous expenditure.
CBSE: Class 12
Multiplier Observation
- The final increase in output and aggregate demand is greater than the initial increase in autonomous expenditure.
- Thus, an initial increment in autonomous expenditure seems to have a multiplier effect on equilibrium output and aggregate demand.
CBSE: Class 12
Key Points: Effect of an Autonomous Change in Aggregate Demand on Income and Output
- Equilibrium income is where the AD curve cuts the 45° line (AD = Output).
- An autonomous rise in investment shifts the AD curve upward, creating excess demand.
- Firms increase output in response to excess demand, raising income.
- The final increase in equilibrium income is greater than the initial increase in autonomous expenditure, indicating a multiplier effect.
