Teaching Supply and Demand Economics with PowerPoint
These slides are examples of one of the 17 PowerPoint
presentations on the PowerPoint CD. The animation effects are missing
since the slides shown here have been converted to images instead of PowerPoint
slides which have animation and sound.
There are 109 PowerPoint Slides just in this one Presentation of 17
Presentations on the CD. Over a thousand PowerPoint animated Slides all on
Demand – Chapter 3
1. Pick-up line for a female economics student: “Oh I understand, It is a matter
of supply and demand, and you da man.”
2. Individual demand is one person’s demand for a good or
service. Market demand is everyone’s demand for that good
3. Taking individual demand and extrapolating it into
4. This is more of individual and market demand.
5. This slide goes from one person to 51 to illustrate who “everyone” is.
6. This slide shows why athletes command so much money. They are in
small supply but there is big demand for their services.
7. Van Gogh’s painting of “Sunflowers” brought $39.9 million in an auction in
8. Van Gogh’s “Self-portrait” brought $71.5 million because of
high demand for a Van Gogh.
9. Markets are where the potential buyers and sellers get
10. Demand – consumers “willingness to buy”. The lower the price, the more we
want to buy. The higher the price, the less we want to buy. This inverse
relationship is called the “law of demand.”
11. Demand is always changing. This slide shows things that were in demand a few
years ago. Popular movies and increases in taste may increase or create demand.
12. This slide shows many things that were popular in the last 12 months. Many
of these things are new or have dramatically come down in price.
13. This is a “demand schedule”, which shows that
“quantity demanded” increases with a decrease in price and decreases with an
increase in price.
14. This shows the “law of demand” where the price of coke
goes from .60 to .25 to .10 and new buyers are drinking coke because of the
substitution effect and income effect.
15. This summarizes the “law of demand”, which is
triggered by a price change and results in a point to point movement on a stable
16. Henry Ford dropped the price on his Model T from $850 to $260 to increase.
He made a famous “law of demand” classic statement by
saying, “Every time I reduce the price of our car by $1, I get a thousand new
17. This cartoon appeared in the Dallas Morning News with a common mistake. The
price of lemonade went up from .5 to .15 and Oliver says there was a “decrease
in demand.” Because there was a price change, he should have said there was a “decrease
18. This is the same cartoon with the corrected “change in QD”
answer, showing the point to point movement on a stable demand curve rather than
a shift of the whole demand curve.
19. This summarizes the 3 reasons for the downward sloping demand curve. The
first one is the “law of diminishing marginal utility”,
which means that as we consume an item we will keep consuming more of it unless
the price is lowered.
20. This continues the previous slide explanation of the reasons for the
downward sloping demand curve. It emphasis the “income effect”,
that as price drops, we are richer and tend to consume more.
