In a hypothetical economy, if entire additional income is consumed, the value of investment multiplier would be ____ . (Fill up the blank with the correct alternative.)
- The investment multiplier is calculated as \(\frac{1}{1 - {MPC}}\), where MPC is the marginal propensity to consume.
- If the entire income is consumed, the MPC = 1, leading to an infinite multiplier because \(\frac{1}{1 - 1} = \infty\).
- Hence, the value of the investment multiplier in this case is infinity.
Conclusion: When all additional income is consumed, the investment multiplier becomes infinite because every increase in income leads to an equivalent increase in consumption, stimulating constant economic growth.
Read the following statements carefully:
Statement 1: Expost savings and Expost investments are equal at all levels of income.
Statement 2: Under the effective demand principle, the equilibrium output is equal to exante Aggregate Demand (AD). In the light of the given statements, choose the correct alternative from the following:
The level of income where Average Propensity to Save (APS) becomes zero is at Income = Rs. 100 crore, since savings (\( S = Y - C \)) equals zero at this point.
Identify, what does the shaded area (change in EFG), in the given figure indicate?

I. Consumption > Income
II. Saving = Zero (0)
III. Consumption < Income
IV. Saving < Zero (0)
