Calculate equilibrium level of income for a hypothetical economy, for which it is given that:
a) Autonomous Investments = ₹ 500 crores, and
b) Consumption function, C = 100 + 0.80Y

Calculate Change in Income (ΔY) for a hypothetical economy. Given that:
a) Marginal Propensity to Consume (MPC) = 0.8, and
b) Change in Investment (ΔI) = ₹1,000 crores
1 Answers
Given Consumption function is,
C=100+0.8 Y
Autonomous investments = 500 crores
We know, at equilibrium level
Y = C+I
Y = 100+0.8 Y+500
Y-0.8Y = 600
0.2 Y = 600
Y = ₹ 3,000 crores
Or
Given Δ I = ₹1,000 crores
MPC = 0.8
As we know,
Multiplier (K) = \(\frac{1}{1-MPC}\) = \(\frac{1}{1-0.8}\)= \(\frac{1}{0.2}\) = 5 times
We know K = \(\frac{ΔY}{Δ1}\)
5 = \(\frac{ΔY}{1000}\)
ΔY = ₹ 5,000 crores
