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 purple point ( diamond symbol) to shade the area representing total producer surplus (PS) at the equilibrium price.

The black line on the following graph shows the tax wedge created by a tax of $80 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.
