MPC is the proportion of additional income that an individual desires to consume.The tax multiplier is the ratio of the change in essence production to an autonomous change in government taxes when consumption is the only induced expenditure.

Because they add up to 100 percent, as MPS increases, MPC decreases and vice versa.
