1. Demonstrate how the intersect of supply and demand curves

Objectives:
1. Demonstrate how the intersect of supply and demand
curves equals price/market equilibrium.
3. Demonstrate consumer/supplier surplus on a given
supply and demand curve.
4. Apply knowledge of supply and demand determinants to
given scenarios--predict changes in price, quantity.
FMA: Scenario: Assume a perfectly
competitive market and that hot dogs
are an inferior good while steak is a
normal good. What happened
to the market for hot dogs after an
unexpected tax rebate check was sent
to all taxpayer? Steak? A1 sauce?
Explain each in properly labeled graph.

Notes:
Diminishing Marginal Utility-Each successive
unit of a product yields less and less usefulness.
Therefore, consumers will only purchase more if
price gets better.
Examples: How many houses would you want to
own? At $300,000? At $200,000? At 100,000?
This is the underlying reason for the law of
demand. We want more at low pricesÍž less at
high.

Elasticity of Demand (and Supply)
Sometimes people are more responsive to changes in price than others.
Elastic Demand (or supply)--when a change in price causes a big change in quantity demanded
What are some things people
might be very responsive to
change in price?
Inelastic Demand (or supply)--when a change in price causes a small change in quantity demanded.

Do you think these could happen? Any examples you can think of?
Perfectly Elastic Key­if a good has a large number of very, very, very close (that is, perfect) substitutes. Example­­paper clip from a specific company.
