MPC and APC.
Explanation of Solution
MPC is associated to the changes that occur in income and spending. Hence, MPC is calculated by
However, in the case of APC, it is an average where the total amount spent on consumption is compared to the total income earned. Hence, it is calculated as follows:
When there is in increase in the income, two choices available are either to spend or to save the money. As MPC is associated to changes on spent income, the amount that is not spent will have to be saved and this becomes MPS. So, the numerator will have change in the money spent or saved and when added together it has to be the total change in income. So, the denominator will have the total change in income. One will be the result when adding MPS and MPC.
Concept Introduction:
Marginal propensity to consume: Marginal propensity to consume refers to the sensitivity of change in the consumption level due to changes occurred in the income level.
Marginal propensity to save (MPS): Marginal propensity to save refers to the sensitivity of change in the saving level due to changes occurred in the income level.

- 1. According to the Bureau of Economic Analysis, during therecession of 2007–2009, household saving as a fraction of dis-posable personal income increased from a low of just over1 percent in the first quarter of 2008 to 5 percent in the secondquarter of 2009. All else equal, what impact would this changein saving have on the MPC, MPS, and multiplier? How wouldthis change affect equilibrium output when planned invest-ment changes? 2.
