Consider the market for air conditioning units. The following graph shows the demand and supply for air conditioning units before the government imposes any taxes. First, use the black point (plus symbol) to indicate the equilibrium price and quantity of air conditioning units 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. 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. Suppose the government imposes an excise tax on air conditioning units. The black line on the following graph shows the tax wedge created by a tax of $120 per air conditioner. 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..

1. Consider the market for air conditioning units. The following graph shows the demand and
supply for air conditioning units before the government imposes any taxes. First, use the black
point (plus symbol) to indicate the equilibrium price and quantity of air conditioning units 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.
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.
Suppose the government imposes an excise tax on air conditioning units. The black line on the
following graph shows the tax wedge created by a tax of $120 per air conditioner. 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.
