Price of car (thousands of dollars) $56 55 54 53 52 51 50 49 48 47 0 20 40 60 80 100 120 140 Quantity of cars (thousands) a. Under the tax, what is the price paid by consumers? What is the price received by producers? What is the government tax revenue from the excise tax? Qver time, the tax on luxury automobiles was slowly phased out (and completely elimi- nated in 2002). Suppose that the excise tax falls from $6,000 per car to $4,500 per car. b. After the reduction in the excise tax from $6,000 to $4,500 per car, what is the price paid by consumers? What is the price received by producers? What is tax rev- enue now? . Compare the tax revenue created by the taxes in parts a and b. What accounts for the change in tax revenue from the reduction in the excise tax
