Question

Do you agree that MPS cannot be negative, but APS can be?

Bharat Maheshwari · Accepted Answer

Dear student, Yes, I agree with the statement MPS can ever be
negative because MPS(marginal propensity to save) is the ratio of
change in savings and change in the disposable income As change can
never be negative show the resulting MPS can't be negative APS can
be negative when S(Savings) are negative or we say C >
Y(consumption expenditure is greater than the disposable income) as
APS is the ratio between Savings and income therefore when savings
are negative the ratio will also become negative Regards
