Summary • Price controls include price ceilings and price floors. • A price ceiling is a legal maximum on the price of a good or service. An example is rent control. • A price floor is a legal minimum on the price of a good or a service. An example is the minimum wage. • Taxes are used to raise revenue for public purposes. • When the government levies a tax on a good, the equilibrium quantity of the good falls. • A tax on a good places a wedge between the price paid by buyers and the price received by sellers. • The incidence of a tax refers to who bears the burden of a tax. • The incidence of a tax does not depend on whether the tax is levied on buyers or sellers. • The incidence of the tax depends on the price elasticities of supply and demand. • The burden tends to fall on the side of the market that is less elastic.
