- Slide 13
- I would love a pair of shoes! Wow! With each additional pair,
he will get less utility and therefore pay less. Not so much!
- Slide 14
- Women buy 19,000 of the 20,000 pairs of shoes. Wal-Mart sells
20,000 pairs of shoes each hour. A merican women spend $15 billion
each year on shoes. American women spend $5 billion on foot
problems.
- Slide 15
- Im stuffed. I dont want any more! [Disutility has set in!]
- Slide 16
- . I ate one hamburger, and it tasted great. The next two tasted
okay. I wish I hadnt have eaten the 5 th. I cant finish the 6 th.
Disutility [or negative utility]? About this time there is toilet
trauma.

- Slide 18
- Ill pay you $1 to drink another glass. Law of DMU As an
individual consumes more of a good, eventually MU will
decrease.
- Slide 19
- Its been fun, but I think Im entering the diminished marginal
utility [satisfaction] phase of our relationship.
- Slide 20
- Slide 21
- Of course, you might get this!
- Slide 22
- Why does attraction towards ones wife reduce as years of
married life increase? Diminishing Marginal Utility!!!

There are exceptions to Diminishing Marginal Utility. For instance,
if you are.

- Joey ate the equivalent of 1 dog every 8.6 seconds.
mustard-yellow champions belt and a one years supply of hotdogs
from Nathans. $ 25,000 Glutton Bowl, 18 pounds of cows brains For
his victory, he received the coveted mustard-yellow champions belt
and a one years supply of hotdogs from Nathans. The man he defeated
earned $150,000 in one year for similar contests, including $
25,000 for a winning appearance at the Glutton Bowl, in which he
consumed 18 pounds of cows brains. Symbolic of gastronomic
greatness Joey ate 103 Crystal Hamburgers and won $10,000.

- Sonya Thomas [The Black Widow ] at 98 pounds sets the Female
Record at 40
- Slide 27
- Gas prices keep rising but we keep buying!
- Slide 28
- Doesnt the law of demand state that consumers buy less at
higher prices? So, why are we still buying gas?
- Slide 29
- Elasticity of Demand Elasticity of demand is a measure of how
consumers react to a change in price. Inelastic demand is demand
that is not very sensitive to a change in price. Inelastic demand
is demand that is not very sensitive to a change in price. Elastic
demand is demand that is very sensitive to a change in price.
- Slide 30
- Think pants. These pants have inelastic waistbands. The
waistbands do not change if people gain weight.
- Slide 31
- Our demand for gasoline is inelastic. It does not change even
with a price increase.
- Slide 32
- Think pants again! Sweat pants have elastic waistbands. The
pants change depending on the size of the person.
- Slide 33
- Our demand for apple juice is elastic. If the price increases,
we will buy less. Our demand changes.
- Slide 34
- So, why is our demand for apple juice elastic and our demand
for gasoline inelastic?
- Slide 35
- Factors Affecting Elasticity of Demand The following are
factors that can affect the elasticity of demand: The following are
factors that can affect the elasticity of demand: Availability of
Substitutes Relative Importance Necessities Versus Luxuries Time
(It takes time to find substitutes.)
- Slide 36
- Its obvious, isnt it? We can substitute orange juice for apple
juice. Therefore, we deal with a price increase by substituting one
product for another product.
- Slide 37
- However, we cannot substitute milk for gasoline.
- Slide 38
- What is this graph telling us about elasticity of demand?
- Slide 39
- Specific vs. General Market When we talk about Elasticity of
Demand it is important to note if we are talking about the market
in general or are we talking about a specific firm.
- Slide 40
- Total Receipts Test The total receipts test is the way we
figure out whether demand is elastic, unit elastic, or
inelastic.

- Slide 52
- Elasticity and Pricing Policies Understanding Elasticity helps
business determine pricing strategies. If demand is elastic you
lower prices to raise revenue. If demand is inelastic you raise
prices to raise revenue.
