1) If the Federal Reserve wants to up GDP by $400 billion and the MPC=.95, by how much would they need to change government spending? Would G be increasing or would it be decreasing?
2) If instead of using government spending changes, they instead change taxes: by how much would they to change? WOuld they be increasing or would they be decreasing?
1. Government spending multiplier, dY/dG = 1/1-MPC
dG = 400 x (1-0.95)
dG = $20 b
Increase g by 20 b
2. Tax multiplier, dY/dT = -MPC/1-MPC
dY/ dT = -0.95 / (1-0.95)
dT = 400 / -19 = -21.08b
decrease taxes by 21,08 b
dT = -21.05
