2. Taxes and welfare Consider the market for commercial fans. The following graph shows the demand and supply for commercial fans before the government imposes any taxes. First, use the black point (plus symbol) to indicate the equilibrium price and quantity of commercial fans in the absence of a tax. Then use the green point (triangle symbol) to shade the area representing total consumer surplus (CS) at the equilibrium price. Next, use the purpie point (diamond symbol) to shade the area representing total producer surplus (PS) at the equilibrium price. Before Tax 200 180 Equilibrium 160 Demand 140 a 120 Consumer Surplus 100 80 Producer Surplus Supply 60 40 20 100 200 300 400 500 600 700 800 900 1000 QUANTITY (Fans) PRICE (Dollars per fan) Suppose the government imposes an excise tax on commercial fans. The black line on the following graph shows the tax wedge created by a tax of $40 per fan. First, use the tan quadrilateral (dash symbols) to shade the area representing tax revenue. Next, use the green point (triangle symbol) to shade the area representing total consumer surplus after the tax. Then, use the purple point (diamond symbol) to shade the area representing total producer surplus after the tax. Finally, use the black point (plus symbol) to shade the area representing deadweight loss. After Tax 200 180 Tax Revenue 160 Demand 140 120 Consumer Surplus 100 Tax Wedge 80 Producer Surplus Supply 60 40 Deadweight Loss 20 100 200 300 400 500 600 700 800 900 1000 QUANTITY (Fans) PRICE (Dollars per fan) Complete the following table by using the previous graphs to determine the values of consumer and producer surplus before the tax, and consumer surplus, producer surplus, tax revenue, and deadweight loss after the tax. Note: You can determine the areas of different portions of the graph by selecting the relevant area.
