Answer: Decrease government revenue and decrease deadweight loss from the tax.
Explanation:
Decrease gov rev and decrease deadweight loss from the tax.
At AB, the government revenue will be:
= Quantity × Tax rate
= 1 × 5
= 5
The deadweight loss will be:
Deadweight Loss= 0.5 × Change in quantity × Change in Price
= 0.5 × (9-4) × (2-1)
= 0.5 × 5 × 1
= 2.5
At CD,
the government revenue will be:
= 1.5 × 2.5
= 3.75
The deadweight loss will be:
= 0.5 × (7.5-5) × (2-1.5)
= 0.5 × 2.5 × 0.5
= 0.625
Based on the calculation above, both the government revenue and the deadweight loss decreases.
