(a) In the multiplier process, increase in income in the first round is always equal to additional investment. So, Increase in income in the first round =Rs.1,000=Rs.1,000 crores.
(b) The saving off Rs. 200 crores indicates that increase in consumption will be Rs. 800 crores in the first round.
- additonal consumption of Rs. 800 crores out of an additional income of Rs. 1,000 indicates that 80% of income is spent, Le. MPC = 0.8. The values of second and third round are calculated on the basis of this data.
(c) Total Increase in Income = Additional Investment x kxk. In the given case:
Multiplier (k)=11−MPC=11−0.8=5(k)=11−MPC=11−0.8=5
So, Total Increase in Income =1,000×5=Rs.5,000 crores=1,000×5=Rs.5,000crores
(d) Total Increase in Consumption == Total increase in Income ×× MPC =5,000 x 0.8=Rs.4,000 crores=5,000x0.8=Rs.4,000crores.
(e) Total Increase in Saving == Total Increase in Income −− Total Increase in Consumption =5,000−4,000=1,000 crores=5,000−4,000=1,000crores.
(f) Values of All other Rounds' is calculated after subtracting the values of first, second and third round from the total increase in income, consumption and saving respectively.
