1. PowerPoint 5 Unit 2 Economics
Microeconomics: Supply, Demand, and Government Policies

2. Essential Questions
How does the government effect the economy through set prices?
Which cases in this PowerPoint do you feel that government control of prices are good? Explain why
Which ones do you feel are harmful? Explain why

3. Supply, Demand, and Government Policies
In a free, unregulated market system, market forces establish equilibrium prices and exchange quantities.
While equilibrium conditions may be efficient, it may be true that not everyone is satisfied.
One of the roles of economists is to use their theories to assist in the development of policies.

4. Controls on Prices
Controls on Prices are usually enacted when policymakers believe the market price is unfair to buyers or sellers.
This results in government-created price ceilings and floors.

5. Price Controls
Price controls are legal restrictions on how high or low a market price may go.
Two kinds of price controls:
Price Ceilings: a maximum price sellers are allowed to charge for a good. It's an upper limit for the price.
Price Floors: a minimum price buyers are required to pay for a good. It’s a lower limit for the price.

6. Example: 1973 OPEC
In 1973, OPEC raised the price of crude oil in world markets. Crude oil is the major input in gasoline, so the higher oil prices reduced the supply of gasoline.
What was responsible for the long gas lines?
Economists blame government regulations that limited the price oil companies could charge for gasoline.
Why did they blame our government and not OPEC?

7. Price Ceiling on Gas imposed by the President
 In the 1970s, when the price of crude oil tripled on the world market the then President of United States, Nixon imposed a price ceiling, on both crude oil and gasoline. There was a maximum price allowed by law to be charged for gasoline.
Why did President Nixon put a price ceiling on oil and gas?
How did the gas stations react? Why?
What did it cause?

8. Price Ceiling Example:
The concept of rent control is a form of price ceiling. The local government can limit how much a landlord can charge a tenant or by how much the landlord can increase prices annually. Rent control aims to ensure the quality and affordability of housing on the rental market.

9. Example: Rent Control
Rent controls are ceilings placed on the rents that landlords may charge their tenants.
The goal of rent control policy is to help the poor by making housing more affordable.
One economist called rent control “the best way to destroy a city, other than bombing.”

10. Price Floors

11. How Price Floors Affect Market Outcomes
A price floor prevents supply and demand from moving toward the equilibrium price and quantity.
When the market price hits the floor, it can fall no further, and the market price equals the floor price.

13. Example: The Minimum Wage
An important example of a price floor is the minimum wage.
Minimum wage laws dictate the lowest price possible for labor that any employer may pay.

16. Summary of Price Ceilings and Price Floors
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.

17. TAXES
Governments levy taxes to raise revenue to run the government, provide public services, and complete government projects.

18. How Taxes on Buyers (and Sellers) Affect Market Outcomes
Taxes discourage market activity.
When a good is taxed, the quantity sold is smaller.
Buyers and sellers share the tax burden.

19. How Taxes on Buyers Affect Market Outcomes
Elasticity and tax incidence
Tax incidence is the manner in which the burden of a tax is shared among participants in a market.
Taxes result in a change in market equilibrium.
Buyers pay more and sellers receive less, regardless of whom the tax is levied on.

20. Elasticity and Tax Incidence
What was the impact of tax?
Taxes discourage market activity.
When a good is taxed, the quantity sold is smaller.
Buyers and sellers share the tax burden.

21. Tax Summary 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.
