ECON 1 Lecture Notes - Lecture 6: Price Ceiling, Price Floor, Tax Incidence
ECON 1: Chapter 6 Notes
Focus Questions:
• What are price ceilings and price floors?
What are some examples of each?
• How do price ceilings and price floors affect market outcomes?
• How do taxes affect market outcomes?
How do the effects depend on whether
the tax is imposed on buyers or sellers?
• What is the incidence of a tax?
What determines the incidence?
Government Policies That Alter the Private Market Outcome
▪ Price controls
▪ Price ceiling: a legal maximum on the price
of a good or service Example: rent control
▪ Price floor: a legal minimum on the price of
a good or service Example: minimum wage
▪ Taxes
▪ The govt can make buyers or sellers pay a specific amount on each unit.
• We will use the supply/demand model to see how each policy affects the market outcome (the price
buyers pay, the price sellers receive, and eq’m quantity).
How Price Ceilings Affect Market Outcomes
Shortages and Rationing
• With a shortage, sellers must ration the goods among buyers.
• Some rationing mechanisms: (1) Long lines/waiting times (2) Discrimination according to sellers’
biases (3) Lotteries (4) First come first served
• These mechanisms are often unfair, and inefficient: the goods do not necessarily go to the buyers who
value them most highly.
• In contrast, when prices are not controlled,
the rationing mechanism is efficient (the goods
go to the buyers that value them most highly)
and impersonal (and thus fair).
How Price Floors Affect Market Outcomes
The Minimum Wage
Evaluating Price Controls
▪ Recall one of the Ten Principles from Chapter 1:
Markets are usually a good way
to organize economic activity.
