4. Elasticity and Tax Incidence – Conclusion
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.
Buyers bear most of the burden of the tax.
Small elasticity of supply: Sellers do not have good alternatives to producing this good.
Sellers bear most of the burden of the tax.
When the government levies a tax on a good, the equilibrium quantity of the good falls.
The tax places a wedge between the price paid by buyers and the price received by sellers.
Buyers pay more for the good and sellers receive less for it.
Buyers and sellers share the tax burden.
The incidence of tax depends on the price elasticities of supply and demand.
Most of the burden falls on the side of the market that is less elastic.
