For a hypothetical economy, C = 200+0.8Y (where c= consumption and Y= Income) and Autonomous Investment = 400 crore. Value of Investment multiplier (k) = _____.

Solution

✅ Correct Option: 3

From C=200+0.8YC = 200 + 0.8Y, the marginal propensity to consume is MPC=0.8MPC = 0.8. Investment multiplier k=11−MPC=11−0.8=10.2=5k = \frac{1}{1-MPC} = \frac{1}{1-0.8} = \frac{1}{0.2} = 5. The level of autonomous investment does not affect the value of the multiplier.
