Suppose the government increases education spending by [tex]$30 billion. If the marginal propensity to consume is 0.96, how much will total spending increase?

Instructions: Round your response to one decimal place.

$[/tex]\text{Total spending increase: } \boxed{\[tex]$ \text{billion}}$[/tex]



Answer :

To determine the total increase in spending due to the government's increase in education spending, we will use the concept of the spending multiplier in macroeconomics. Here is a step-by-step solution:

1. Understanding the Problem:
- The government increases education spending by [tex]$30 billion. - The marginal propensity to consume (MPC) is 0.96. - We need to find out how much the total spending will increase. 2. Calculate the Spending Multiplier: - The spending multiplier (k) is derived from the marginal propensity to consume (MPC) using the formula: \[ k = \frac{1}{1 - MPC} \] - Plug in the given MPC of 0.96 into the formula: \[ k = \frac{1}{1 - 0.96} \] - Simplify the denominator first: \[ 1 - 0.96 = 0.04 \] - Now calculate the multiplier: \[ k = \frac{1}{0.04} = 25 \] 3. Calculate the Total Increase in Spending: - The total increase in spending is found by multiplying the initial increase in spending by the spending multiplier: \[ \text{Total Increase in Spending} = \text{Increase in Education Spending} \times k \] - Given the increase in education spending is $[/tex]30 billion, we calculate:
[tex]\[ \text{Total Increase in Spending} = 30 \, \text{billion dollars} \times 25 = 750 \, \text{billion dollars} \][/tex]

4. Conclusion:
- The total increase in spending due to the government's [tex]$30 billion increase in education spending, given a marginal propensity to consume of 0.96, is $[/tex]750 billion.
- Therefore, the final rounded answer is:
[tex]\[ \boxed{750.0 \, \text{billion dollars}} \][/tex]
