Raises revenue D 1 D 2 Quantity © 2014 by McGraw-Hill Education 2. and changes behavior. • As a tax is levied on consumers, the demand curve shifts down by the amount of the tax. • Raises revenue for the government. • Changes behavior of buyers and sellers. 3 1 Principles of taxation Each tax considered must compare trade-offs between revenue and inefficiency. Price ($) 100 1. Tax creates a new demand curve $20 below 90 2. which moves equilibrium to a lower quantity. 80 S 70 60 • Taxes cause changes in behavior and a deadweight loss to occur. – A $20 tax on jeans shifts the demand curve downward. – Deadweight loss is the loss of total surplus that occurs because the quantity of a good that is bought and sold is below the market equilibrium quantity. – Inefficiency is loss in total surplus. Deadweight loss is surplus lost due to the reduced quantity. 50 40 30 D1 20 10 D2 1 0 2 3 4 5 6 7 Quantity of jeans (millions of pairs) © 2014 by McGraw-Hill Education 4 Principles of taxation The size of deadweight loss is determined by the price elasticity of supply and demand.
