  • Example Betty doesnt have the 60,000 to buy a
    Porsche. If she did have the money, though, she
    says that she would buy it. Betty has the
    willingness but not the ability. Under these
    circumstances she does not have a demand for the
    Porsche!

8
SPECIAL HOMEWORK TONIGHT!!!
  • Many people believe that the more money a person
    has, the more expensive version of a product that
    person will buy.
  • People are assuming that someone who has the
    ability to buy something also has the willingness
    to buy it.
  • Economists dont think this waythey know most
    people try to find the best deal!

9
Thinking like an Economist! (Please note this is
not on p. 91 of your textbookeven though that is
what the log says)
  • Survey 5 people whether they buy the most
    expensive items available when they can afford
    them, or look for best buys even when they have
    more than enough money for the most expensive
    items.
  • Create the following chart on a separate piece of
    paper

  • The graph is a called a curve.
  • The curve always slopes downward from left to
    right!

22
ReviewTrue or False
  • Both willingness and ability to purchase must be
    present for demand to exist.
  • TRUE
  • As price decreases, the quantity demanded
    decreases.
  • FALSE
  • The more utility you receive from a good, the
    higher the price you are willing to pay for that
    good.
  • TRUE

23
Summary
  • When completing your notes you need to write a
    3-5 sentence summary of the lecture. This is a
    part of your notes grade!

CLASS WORK/HOMEWORK
  • HOMEWORK REMINDER
  • Workbook pages 36-38 due Wed in class

20. Lecture 11 Demand Part 2

When Demand Changes, the Curve Shifts
  • Demand can change
  • When Demand goes upthe curve shifts to the
    right
  • When Demand goes downthe curve shifts to the
    left

Remember when taking Cornell Notes you need to
come up with at least 3 questions per page!

Answer the following questions in your notebook
  • In the graph, the demand curve in the middle, the
    one labeled D1, is the starting point. On this
    curve, what is the quantity demanded at a price
    of 1?

Answer the following questions in your notebook
  • Suppose the demand for Orange Juice increases to
    600 quarts. People still want to pay 1 per
    quart, but now they want to buy more at that
    price. What happened to the demand curve?
  • It shifts to the right and becomes D2. When
    demand goes up, the demand curve shifts to the
    right!

Answer the following questions in your notebook
  • Now suppose that the demand for Orange Juice
    decreases to 200 quarts. What happens to the
    demand curve?
  • It shifts to the left and becomes D3. When
    demand goes down, the demand curve shifts to the
    left.

In your notebook brainstorm a list answering the
following question
  • Make a list of the most popular holiday gifts
    from last year.
  • What are some of the reasons that the demand for
    these items was so high?
  • Do you think the demand will be as high again
    this year? Why or why not?

What factors cause demand curves to shift?

What factors cause demand curves to shift?
As gas prices soar, fewer SUVs are being
purchased while more hybrids are being sold every
day!

37
What is Elasticity of Demand?
38
What is Elasticity of Demand?
Copy the formula!
Elasticity is determined using the following
formula
To find the percentage change in quantity
demanded or price, use the following formula
subtract the new number from the original number,
and divide the result by the original number.
Ignore any negative signs, and multiply by 100 to
convert this number to a percentage

ReviewTrue or False
  • When a demand curve shifts to the right, demand
    has decreased.
  • FALSE
  • Demand has increased when the demand curve shifts
    to the right.
  • TRUE
  • The prices of related goods affect the demand
    curve.
  • TRUE
  • A change in the number of buyers creates a change
    in the quantity demanded.
  • TRUE

49
ReviewTrue or False
  • Demand is always inelastic.
  • FALSE
  • Unit-elastic demand exists when the quantity
    demanded is less than the percentage change in
    price.
  • FALSE
  • Time affects the elasticity of demand.
  • TRUE
  • The demand for necessities is likely to be
    inelastic.
  • TRUE
  • It doesnt matter if demand is elastic,
    inelastic, or unit-elastic.
  • FALSE
