Correct option is C
Correct Answer: (c) Investment multiplier
Investment Multiplier:
The investment multiplier measures how much the equilibrium output (final goods and services) changes due to a change in autonomous investment or expenditure.
It is derived from the concept of the multiplier effect, where an initial increase in spending generates multiple rounds of economic activity, leading to a magnified impact on output.
Formula:
Where:
k: Investment multiplier
MPC: Marginal Propensity to Consume
The higher the MPC, the larger the multiplier effect.
Consumption Multiplier:
- This term does not exist as a formal macroeconomic concept. Consumption is a part of the multiplier effect but does not describe the phenomenon itself.
Income Multiplier:
- While the multiplier effect influences income, the correct term for this concept is the
investment multiplier.
- Savings impact the multiplier effect indirectly through the Marginal Propensity to Save (MPS), but the term "savings multiplier" is not used in this context.
