Answer:
See the explanation below.
Explanation:
Multiplier = 1/(1-MPC)
a. For each value of the MPC, calculate the expenditure multiplier, or the impact of a one-dollar increase in government spending on GDP.
Multiplier for 0.82 = 1/(1-0.82) = 1/0.18 = 5.6
Multiplier for 0.75 = 1/(1-0.75) = 1/0.25 = 4.0
Multiplier for 0.55 = 1/(1-0.55) = 1/0.45 = 2.2
b. For each value of the MPC, calculate the impact on GDP of a $250 million increase in government spending.
For 0.82 MPC, Impact on GDP = 5.6 * 250,000,000 = $1,388,888,888.9
For 0.75 MPC, Impact on GDP = 4.0 *250,000,000 = $1,000,000,000.0
For 0.55 MPC, Impact on GDP = 2.2 *250,000,000 = $555,555,555.6
