Answer #1

(c.) At equilibrium, the value of total injections is $280 and of total leakages is $280.

Explanation

Total injections = I + G + X

total injections = 50 + 180 + 50

Therefore, total injections = $280

Total leakages = T + S + IM

total leakages = 140 + 70 + 70

Therefore, total leakages = $280

(d.) The value of the MPE in Arkinia is 0.10.

(e.) The value of the multiplier in Arkinia is 1.72.

Explanation

The value of the multiplier = 1-c+ ct +m

Where, c = MPC, t = MTR and m = MPM

The value of the multiplier = 1-0.65 +(0.65 x 0.20) 0.10

The value of the multiplier 1.72
