Call

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

An economy is in equilibrium. From the following data about an economy investment expenditure. (i) Income=1000 (ii) Marginal propensity to consumption

Y=C+I `Y=bar(C)+bY+I` `Y=bar(C)+bY+I` `10000=100+9000+I` I=10000-9100 I=900

Calculate MPC from the following data about an economy which is in equilibrium: National income=2000, Investment expenditure=100, Autonomous consumpti

`Y=C+I` `Y=(bar(C )+By)+I` `b(2000)=1700 [At equiilbrium S=I=100 2. 1-b=MPS=0.3` `b(1700)/(2000)=0.85` Hence, MPC=0.85

Suppose in a hypothetical economy, the savings increase by ₹ 20 crores when national income increases by ₹ 100 crores. Compute the additional investme

`MPS = "("("Change in Savings")/("Change in Income")")" = "("(DeltaS)/(DeltaY)")" = (20)/(100) = 0.20` Investment Multiplier (K) = `(1)/(MPS) = (1)/(0.20) = 5` Investment Multiplier (K) = `(1)/(MPS) = (1)/(0.20) =...

In an economy equilibrium level of income is Rs. 12,000 crore. The ratio of MPC to MPS is `3 : 1`. Calculate the additional investment needed to reach

Given `MPC` to `MPS=3 :1` i.e. `MPC=0.75` and `MPS=0.25` `Delta Y=20,000-12,000=8,000` crore `DeltaY=DeltaI 1/(MPS)` `8,000=DeltaI 1/(0.25)` `=4 Delta I` `Delta I= Rs. 2,000` crore.
