  1. IB Economics HL Topics Indirect Taxes, Subsidies and Price Controls

  2. Tax Incidence (burden) • Is a measure of the consequences of a tax on all the affected parties • Tax impacts the profitability of any product, the degree may vary • Whoever pays the tax suffers the tax burden

  3. Tax incidence: PED similar to PES Price S + tax S Ptax Tax Revenue Tax burden of consumer Pe Tax burden of producer P1 D Quantity Qtax Qe

  4. PED similar to PES • Consumers and producers share the burden of tax equally • Consumers pay more and receive less output • Consumer and producer surplus decreased • Market size was reduced from Qe to Qtax

  5. Tax incidence: PED > PES Price S + tax S Ptax Tax Revenue Tax burden of consumer Pe Tax burden of producer P1 D Quantity Qtax Qe

  6. PED > PES • Demand is more elastic than supply • Consumers are more responsive to price, and therefore less tolerant of price increases • Producers pay more of the burden of the tax • Government receives less revenue • Market size decreases quite significantly, therefore employment is more likely to decline • Deadweight loss is greater due to large decrease in quantity

  7. Tax incidence: PED < PES Price S + tax S Ptax Tax Revenue Tax burden of consumer Pe producer P1 D Quantity Qtax Qe

  8. PED < PES • Consumers are relatively indifferent to price changes • Consumers tax burden is greater than producers • Government receives more revenue • Market size decreases relatively little, therefore employment is less affected • Deadweight loss is smaller

  9. PED vs PES Summary • The more elastic the demand relative to supply, the greater the burden paid by producers, the greater the deadweight loss, and the smaller the government revenue • The more inelastic the demand relative to supply, the greater the burden paid by consumers, the smaller the deadweight loss, and the greater the government revenue

  10. Government will place indirect taxes on products that have relatively inelastic demand • The demand will change in smaller proportion, gain high revenue and yet not cause a large fall in employment

  11. Size of Deadweight Loss • The deadweight loss of the tax will depend upon two factors: • The size of the tax • The reduction in the quantity sold • The reduction in the quantity sold will depend upon the elasticity of demand and supply • The more elastic demand or supply is the larger the deadweight loss will be • If either demand or supply is price inelastic then the deadweight loss will be small and could be zero if perfectly inelastic (no change in the quantity sold and consumed)

  12. A + B + C = Consumer Surplus (before tax) S = MC A Price buyers PB = pay B E1 maximizes Total Welfare C Price P1 = without tax E D Price sellers PS = receive F D = MB Producer Surplus = D + E + F (before tax) Q2 Q1 Total Welfare before Tax Price E1 0 QTY

  13. Area C + E is a complete loss to Society: (DEADWEIGHT LOSS) S = MC A Price buyers PB = pay B C Price P1 = without tax E D Price sellers PS = receive F D = MB B + D = Tax Revenue Q2 Q1 Tax Affect on Total Welfare Price Quantity 0
