Document Summary
Eco 2023 - lecture 10 - taxes and international trade. If the price paid by the buyers rises by the full amount of the tax, then the full amount of the burden falls on the buyers.

A tax on sellers decreases the supply of the product, so the supply curve shifts to the left. The price paid by buyers rises and the price received by sellers falls.

Tax incidence: the division of the burden of a tax between buyers and seller. The tax incidence depends on the price elasticity of demand and the price elasticity of supply.
