Answer:

(1)  In a closed economy, assuming investment demand is zero,

Y = C + G

Y - C = G

S = G, where

Y: Income, C: Consumption, S: Savings and G: Government spending

So,

S / Y = G / Y [dividing each side by Y]

[tex]\Delta \mathrm{S} / \Delta \mathrm{Y}=\Delta \mathrm{G} / \Delta \mathrm{Y}[/tex]

MPS = $100 billion / $1000 billion = 0.10

(2)  MPC = 1 - MPS = 1 - 0.10 = 0.90
