Question : 3
Total: 21
"In an economy, the autonomous consumption is 100 and Marginal Propensity to Consume (MPC) is 0.6. If the equilibrium level of Income is 2,000 , then the autonomous investment is 300."
Justify the statement with valid calculation.
Solution:  
Given Information:

Autonomous consumption (C)=100
Marginal Propensity to Consume (MPC)=0.6
Equilibrium level of Income( Y ) =2000
Autonomous Investment (I)=300
At equilibrium level, Y=C+I
Thus,2000=1300+I
I=(20001300)
I=700
At this level of income, Y should be 700 but it is given 300 which is not valid.
Working Note:
C=C+bY
=100+0.6(2000)
=100+1200
=1300
