__________ can never be negative while __________ can have value as 1.

Solution

Correct Option: 4

MPS = ΔSΔY\dfrac{\Delta S}{\Delta Y}

Since change in savings ΔS\Delta S is always non-negative relative to change in income ΔY\Delta Y, MPS can never be negative.


APC = CY\dfrac{C}{Y}

At the break-even point, consumption equals income, so:

APC=CY=YY=1APC = \dfrac{C}{Y} = \dfrac{Y}{Y} = 1

Therefore, APC can have a value of 1.


MPS can never be negative while APC can have value as 1.
