Tnvestment multiplier and Marginal Propensity to Consume are directly related to each other'. Explain with the help of numerical example.
Solution:  
Investment multiplier and MPC are directly related to each other. It can be as follows:
K=‌
1
1−MPC

If MPC‌=0.4
thenK‌=‌
1
1−0.4
=‌
1
0.6

If MPC‌=0.6
thenK‌=‌
1
1−0.6
=‌
1
0.4

∴ Both are directly related with the increase in MPC, investment multiplier will increases.
