Solution:
a):- MACA=180-3EA
EA=60-MACA/3
MACB=100-2EB
EB=50-MACB/2
Aggregate MAC:
E=110-5MAC/6
MAC=132-1.2E
Desired E=80
MAC=132-1.2*80=36
EA=60-36/3=60-12=48
EB=50-36/2=50-18=32
So ,In Equilibrium 3 permit are traded . Firm A bought three permit from firm B.
b):- The Equilibrium price of permit is equal to MAC at Equilibrium ,so permit price =36.
c):- TACA = 180EA - 1.5*(EA)2
Gain to firm a by trading=180*48 - 1.5×48×48 -180×45+1.5×45×45 -36×3 = 13.5
TACB=100EB-(EB)2
Gain of firm B by trading=100×32-32×32-100×35+35×35+36×3 = 9
Net social gain= 13.5+9 = 22.5
