In an economy, the actual level of income is ₹ 500 crores whereas full employment of Y is ₹ 800 crore. MPC = 0.75. Calculate how much change in investment is required to achive full employment level in the economy.
Multiplier(K)=`(DeltaY)/(DeltaI)=1000/250` or K=4
`K=1/(1-MPC)`
`4=1/(1-MPC)` or 4-4MPC
4MPC=3 or `MPC=3/4=0.75`
`MPC=(DeltaC)/(DeltaY)` or `0.75=(DeltaC)/1000`
`DeltaC=₹750 ` crore
`DeltaS=DeltaY-DeltaC=1000-750=₹250` crore
(a) Refer to section 8.2.3 of chapter 8.
(b) It is justified to say that an economy generally operates at less than full employment level. It is because economy is...
We know that consumption function is: `" " C = barc + MPC.Y`
At euilibrium level of Income in the economy Y = C + 1
Given, Autonomous Consumption (`barC`)...
