Given the following information, QD = 240-5P QS= P Where QD is the quantity demanded, Qs is the quantity supplied and P is the price. Suppose the government decides to impose a tax of $12 per unit on sellers in this market. Determine the total surplus after tax.
Total surplus after tax is the sum of consumer surplus, producer surplus and revenue of government
Before tax, we have QD = QS which gives P = 240/6 = 40 and Q = 40
After tax we have QD = QS + tax which gives P = 252/6 = 42 paid by buyers, P = 30 received by sellers and Q = 30
Total surplus after tax = CS + PS + Revenue
= 0.5*(48-42)*30 + 0.5*(30-0)*30 + 12*30
= 900
It is $900
