If in an economy :
Change in initial Investment (∆I) = ₹ 700 crores
Marginal Propensity to Save (MPS) = 0.2
(a) Investment Multiplier (k)
(b) Change in final income (∆Y)
उत्तर
(a) We know,
`k = 1/(MPS) = 1/0.2 = 5`
So, investment multiplier is 5.
(b) We also know,
`k = (∆"Y")/(∆"I")`
`5 = (∆"Y")/(700)`
∆Y = 3,500
So, change in income is ₹ 3,500 crores

Calculate investment expenditure from the following data about an economy which is in equilibrium:
National income = 1000
Marginal propensity to save = 0.25
Autonomous consumption expenditure = 200
The value of marginal propensity to consume is 0.6 and initial income in the economy is Rs 100 crores. Prepare a schedule showing Income, Consumption and Saving. Also show the equilibrium level of income by assuming autonomous investment of Rs 80 crores.
Assuming that increase in investment is Rs. 800 crore and marginal propensity to consume is 0.8, explain the working of multiplier

If the marginal propensity to consume is greater than marginal propensity to save, the value of the multiplier will be:
Income rises from ₹50,000 to ₹60,000, consumption increases from ₹40,000 to ₹48,000. In this situation, what will be the value of Marginal Propensity to Consume (MPC)?
