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 or service.
3. Taking individual demand and extrapolating it into market demand.
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 1987.
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 together.
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 demand curve.
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 buyers.”
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 in QD.”
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.
