Greeley [361]

Based on the marginal propensity to save, MPS , the national income will increase by a maximum of $20 billion.

<h3>What is marginal propensity to save?</h3>

Marginal propensity to save (MPS) is a measure of how savings will change, given a change in income.

Marginal propensity to save is related to marginal propensity to consume, MPC by the formula:

  • MPS + MPC = 1

Grom the given value of MPS,

MPC = 1 - 0.25

Therefore, MPC = 0.75

Also, the formula for calculating marginal propensity to consume is given as:

  • Marginal propensity, MPC = ΔC/ΔY

Where:

  • ΔC is a change in consumption
  • ΔY is a change in income

ΔY = ΔC/MPC

ΔY = $15 billion/0.75

ΔY = $20 billion

Therefore, the national income will increase by a maximum of $20 billion.
