Assume the MPC is .63. If government increases spending by $500 Million in the economy to stimulate economy performance, what is the total change in GDP?
Solution:-
Change in GDP = change in spending x multiplier
Multiplier – 1/MPS
MPC + MPS = 1
MPC + MPS = 1
0.63 + MPC = 1
MPS = 0.37
Multiplier = 1/MPS = 1/1-MPC = 1/0.37 = 2.7
Change in GDP = change in spending x multiplier
= $500 * 2.7
= $1350
The total change in GDP is $1350.
