6 A tax on sellers Price of A tax on sellers Ice-Cream
Cone A tax on sellers shifts the supply curve upward by the size of the tax ($0.50). Demand, D1 Equilibrium with tax S2 Price buyers pay S1 $3.30 Price without tax Tax ($0.50) 90 3.00 Equilibrium without tax 100 2.80 Price sellers receive Quantity of Ice-Cream Cones When a tax of $0.50 is levied on sellers, the supply curve shifts up by $0.50 from S1 to S2. The equilibrium quantity falls from 100 to 90 cones. The price that buyers pay rises from $3.00 to $3.30. The price that sellers receive (after paying the tax) falls from $3.00 to $2.80. Even though the tax is levied on sellers, buyers and sellers share the burden of the tax.

Taxes How taxes on sellers affect market outcomes
Taxes discourage market activity Smaller quantity sold Buyers and sellers share the burden of tax Buyers pay more Worse off Sellers receive less Get the higher price but pay the tax Overall: effective price fall

Taxes How taxes on buyers affect market outcomes
Initial impact on the demand Demand curve shifts left Lower equilibrium price Lower equilibrium quantity The tax – reduces the size of the market

7 A tax on buyers Price of Ice-Cream Cone Equilibrium with tax Price
D1 Equilibrium with tax Price buyers pay Supply, S1 Equilibrium without tax D2 $3.30 Price without tax Tax ($0.50) 90 A tax on buyers shifts the demand curve downward by the size of the tax ($0.50). 3.00 100 2.80 Price sellers receive Quantity of Ice-Cream Cones When a tax of $0.50 is levied on buyers, the demand curve shifts down by $0.50 from D1 to D2. The equilibrium quantity falls from 100 to 90 cones. The price that sellers receive falls from $3.00 to $2.80. The price that buyers pay (including the tax) rises from $3.00 to $3.30. Even though the tax is levied on buyers, buyers and sellers share the burden of the tax.

Taxes How taxes on buyers affect market outcomes
Buyers and sellers share the burden of the tax Sellers get a lower price Worse off Buyers pay a lower market price Effective price (with tax) rises Taxes levied on sellers and taxes levied on buyers are equivalent

Effect of a per-unit (sales) tax on everyone

Taxes Elasticity and tax incidence Dividing the tax burden
Very elastic supply and relatively inelastic demand Sellers – small burden of tax Buyers – most of the burden Relatively inelastic supply and very elastic demand Sellers – most of the tax burden Buyers – small burden

How the burden of a tax is divided (a)
9 How the burden of a tax is divided (a) (a) Elastic Supply, Inelastic Demand Price 1. When supply is more elastic than demand . . . Demand Supply Price buyers pay Tax The incidence of the tax falls more heavily on consumers . . . Price without tax Price sellers receive Than on producers. Quantity In panel (a), the supply curve is elastic, and the demand curve is inelastic. In this case, the price received by sellers falls only slightly, while the price paid by buyers rises substantially. Thus, buyers bear most of the burden of the tax.

Than on consumers Price without tax The incidence of the tax falls more heavily on producers. Price sellers receive Quantity In panel (b), the supply curve is inelastic, and the demand curve is elastic. In this case, the price received by sellers falls substantially, while the price paid by buyers rises only slightly. Thus, sellers bear most of the burden of the tax.

Taxes Tax burden - falls more heavily on the side of the market that is less elastic Small elasticity of demand Buyers do not have good alternatives to consuming this good Small elasticity of supply Sellers do not have good alternatives to producing this good

1993 – most of the luxury tax – repealed
Who pays the luxury tax? new luxury tax Goal: to raise revenue from those who could most easily afford to pay Luxury items Demand - quite elastic Supply - relatively inelastic Outcome: Burden of a tax falls largely on the suppliers 1993 – most of the luxury tax – repealed
