Unit Two: Learning Objectives:
North Clackamas School District
Social Studies Priority Standards:
• HS.51 (A): Explain how supply and
demand represents economic activity
and describe the factors that cause them
to shift.
Lesson One: Daily Learning Target
I Can define and explain in writing the
following key Economic concepts:
Law of Demand
Substitution Effect
Income Effect
Why do roses cost more on Valentine’s Day?
Why do TV ads cost more during the Super Bowl
($4 million for 30 sec.) than during Nick at Nite reruns?
Why do hotel rooms in Sun Valley, Idaho cost
more in the winter than in the summer?
Why do surgeons earn more than butchers?
Why do pro basketball players earn more than pro hockey players?
“Econ, Econ”
Why do Christmas lights go on sale December 26th?
Why can I pay $40 to see Hall and Oates at the Schnitzer in 2014
When in 1984 it would have cost me $100 at Memorial Coliseum?
The answer to these and other economics questions boil down to the workings of
supply and demand – the subject of this chapter.

Demand
A relationship between
price and quantity
demanded in a given time
period, ceteris paribus.
What is Demand?
• Willing and able to purchase a product at a
particular price
• How many of you would like a Porsche [or like
vehicle]?
• How many of you are able?
• What’s the difference between willing and able?
• Idea of time and place – at this time, you may be
willing to buy a Porsche, but are not able,
therefore you do not have a “DEMAND” for a
Porsche
Markets
In a market economy, the price
of a good is determined by the
interaction of demand and
supply.
Why do we purchase more when a sale
occurs?
It’s obvious, isn’t it? Consumers
love low prices!
Look at this demand curve.
What happens to quantity purchased
as prices rise?
As price goes down,
demand goes up!

The Law of Demand
The law of demand states that
consumers buy more of a good
when its price decreases.
Conversely, consumers buy less of
a good when its price increases.
Consumers love low prices.
It really depends on the price, doesn’t it?
The Substitution
Effect
One reason that the law of demand
exists is the substitution effect.
The substitution effect occurs when a
consumer reacts to an increase in a
good’s price by buying less of that
good and more of a similar yet cheaper
good.
When the price of orange juice rises,
consumers substitute cheaper apple
juice for orange juice.

 Lower prices allow consumers to
increase demand.
 Lower prices increase consumers’
purchasing power.
 This is known as the “income Effect”
The Income Effect
• The income effect is the change in
consumption resulting from a change
in income.
• In other words, when prices rise, your
money buys less.
• Higher prices reduce your purchasing
power.

Economists love graphs because graphs
provide easy understanding of economic
concepts.
If a picture is worth a thousand words,
a graph is worth even more.
A demand schedule records the quantity
demanded at various prices.
A demand schedule can easily be
converted to a demand curve.
Demand curve
Draw a Demand curve now. With a verical
“price” line and a horizontal “quantity line” and
a “0” at the axis.
Now plot out the numbers from this demand

Demand curve
Draw another Demand curve again. With a
verical “price” line and a horizontal “quantity
line” and a “0” at the axis.
Law of Demand
Remember: As price falls, the quantity
demanded increases. As the price rises, the
quantity demanded decreases
