Given the following set of data, calculate equilibrium income.
C = 100 + 0.8Y
Investment = ₹ 260 Cr.
Answer & explanation
Correct answer: option 4
The correct answer is: ₹1,800 Cr
Consumption function: In macroeconomics, we often use the consumption function to relate consumption (C) to income (Y).
- A common form of the function is: C = $\overline{C}+c.Y$ (Where $\overline{C}$ is Autonomous expenditure and c is the marginal propensity to consume.)
Given C = 100 + 0.8Y
Investment = 260 Cr
We know that Y= C + I
Y= 100 + 0.8Y +260
0.2 Y = 360
Y = 360/0.2= Rs 1800 Cr
So, the equilibrium income is ₹1800 Cr.
