Question

find a change in income if multiplier is 4 and increase in investment is rs.15 crore​

Answer 1

Explanation:

Investment multiplier refers to the number of time by which the increase in output or income exceeds the increase in investment. It is measured as the ratio between change in income and change in investment and it is denoted as 'k'.

Multiplier(k) => Change in income / change in investment = 1/ MPS(s) where s is the marginal propensity to save.

So if MPS=MPC then ,

We know that MPC + MPS =1

=> 2 MPS= 1

=> MPS= 1/2

=> MPS= 0.5

Multiplier (K) = 1/ MPS= 2 times.

Hence, the value of the multiplier is two.

Answer 2

Answer:

So the answer is 60 crores
