Value of investment multiplier varies between zero and infinity.
False
False. Value of investment multiplier varies between one and infinity. The minimum value of investment multiplier is 1. It can never be less than one because MPC is never negative. At least it is = 0, and at most it is = 1.
Case 1: MPC = 0, M(or multiplier)=11−MPC=11−0=11=1
Case 2: MPC = 1, M=11−MPC=11−1=10=∞
So that, value of M (multiplier) always varies between 1 and ∞.
