Kyle's marginal propensity to save if his saving increases by $200 after receiving a $1,000 increase in salary is 0.2.
The change in household savings when disposable income rises by one dollar is measured by the marginal propensity to save (MPS). According to the MPC notion, which is a number between 0 and 1, customers often spend only a portion of a dollar's worth of additional disposable income. Customers preserve their extra discretionary income instead of using it. In light of this, the marginal propensity to save (MPS) is the portion of the extra dollar of discretionary income that is saved. Most frequently, Keynesian economic theory uses MPS. It is simply determined by dividing the observed change in savings given a change in income:
MPS = ΔS/ΔY
Where S represents the change in savings, and Y represents the change in income. so 200/1000 would give us 0.2 as the answer above.
The number for MPS can be subtracted from the MPC since there is an inverse relationship between the marginal propensities to spend and save.
