A greater saving will reduce the impact of the multiplier.

Explanation:

A multiplier generally refers to the factor that amplifies or increase the initial change of something else.

In economics, multiplier refers how change in spending or saving results into a larger change in local output and income.

Since addition of marginal propensity to consume (MPC) and marginal propensity to save (MPS) is equal to 1, the formula for calculating a multiplier can be stated as:

Multiplier = 1 / (1 - MPC) or 1/MPS

From the question therefore, when MPS = 0.10, we have:

Multiplier = 1/0.10 = 10

When MPS is increases to 0.20, we have:

Multiplier = 1/0.20 = 5

Since 5 is less than 10, a greater saving will therefore reduce the impact of the multiplier.
