First, find initial equilibrium P and Q: 100 – P = 3P P* = 25 Q* = 75 Stax S Pc Pf D Qtax Need to find Pc and Pf. -for Pc, solve Qd = Qs with tax 100 – P = 3P – 8 P = 27 is what consumers now pay Q = 73 -for Ps, substitute Q = 73 into initial Qs 73 = 3P P = 24.33 is what firms receive The amount of the tax is \$27 – 24.33 = 2.67 The consumers now pay \$2 more. The suppliers now receive \$.67 less. The government’s tax revenue is \$2.67*73 = \$194.91 The deadweight loss is the area of the shaded triangle: DWL = .5*2*2.67 = \$2.67
