Question
Which of the following best represents the savings function? Group of answer choicesSavings = Autonomous Consumption + marginal propensity to save x disposable incomeSavings = Autonomous savings + marginal propensity to save x disposable incomeSavings = Autonomous savings+ marginal propensity to consume x disposable incomeSavings = Autonomous Consumption + marginal propensity to consume x disposable income
Solution
The best representation of the savings function from the given choices is:
Savings = Autonomous savings + marginal propensity to save x disposable income
Here's why:
-
Autonomous savings: This is the amount of savings that occurs regardless of income levels. It's the base level of savings that happens no matter what.
-
Marginal propensity to save (MPS): This is the proportion of an additional income that a person saves rather than spends on consumption. It's how much of each extra dollar of income will be saved.
-
Disposable income: This is the amount of money that households have available for spending and saving after income taxes have been accounted for. It's the income available to save or spend.
So, the savings function is calculated by adding the autonomous savings to the product of the marginal propensity to save and the disposable income. This equation shows that savings are influenced by both a base level of savings and the proportion of disposable income that is saved.
