When the value of MPC is 1, the value of the investment multiplier will be ____________.

1  0  ∞ Value of MPC cannot be 1.

Value of MPC cannot be 1.

MPC and multiplier have positive relation. When MPC is maximum, then multiplier will be maximum. Maximum MPC can have value 1 as MPC + MPS =1. So, when MPC = 1, then multiplier =  \(\frac{ 1}{\text {1 - MPC}}\) = \(\frac{1 }{\text 1 - 1 }\) = C
