Demand you Da-man
  • DEMAND-Always refers to the buyer/consumer of a
    product.

Lyrics
  • Can't buy me love, love Can't buy me love I'll
    buy you a diamond ring my friend if it makes you
    feel alright I'll get you anything my friend if
    it makes you feel alright 'Cause I don't care
    too much for money, money can't buy me love
    I'll give you all I got to give if you say you
    love me too I may not have a lot to give but
    what I got I'll give to you I don't care too
    much for money, money can't buy me love Can't
    buy me love, everybody tells me so Can't buy me
    love, no no no, no Say you don't need no
    diamond ring and I'll be satisfied Tell me that
    you want the kind of thing that money just can't
    buy I don't care too much for money, money can't
    buy me love

  • Does money have any intrinsic value? What are the
    functions of money? How does demand for money
    affect its supply? How do you think the supply of
    money versus the supply of diamonds has changed
    since the since the Beatles wrote this song?
    What's the reason for the difference? Although
    money cant buy love, money can buy a diamond
    ring. How does the money supply change today if
    you pay for the diamond ring with credit as
    opposed to a debit card?

Supply and Demand
  • Song

  • My boss he's a probable bore.Put me hands and
    knees on scrubable floor.Do it right receive the
    lions share bliss.Know all too well just where
    that ration is.Learned a lot about the company
    doe.Learned less about receiving it though.Saw
    how it came to those who always sat pretty.Don't
    need it.Supply and demand.My girl had a
    probable cause or so she said and took a probable
    pause.I was dumped for occupying her time.I
    asked her why and what was next in line.She said
    "Shiny hair that's my life ambitionbut I'll
    devote my time to a new omission the
    rizzle-razzle kitsch of paranoid city".Don't
    need it.Supply and demand.Supply and demand.

8
  • Draw a supply and demand diagram that shows the
    boss receiving the lions share bliss while
    someone who scrubs floors gets much less. In
    other words, what factors would affect supply and
    demand such that CEOs receive 300 times the
    compensation of average workers? Are CEOs paid
    too much?

9
Demand Curve always looks like this. You can look
at it as going down. What do you notice about the
relationship between price and quantity?
10
THE LAW OF DEMAND (Memorize this)
AS PRICES GO UP PEOPLES DEMAND FOR PRODUCT GOES
DOWN AS PRICES GO DOWN PEOPLES DEMAND FOR
PRODUCT GOES UP.
11
The Demand Curve The Relationship between Price
and Quantity Demanded
  • Demand Schedule
  • The demand schedule is a table that shows the
    relationship between the price of the good and
    the quantity demanded.

The Demand Curve The Relationship between Price
and Quantity Demanded
  • Demand Curve
  • The demand curve is a graph of the relationship
    between the price of a good and the quantity
    demanded.

Shifts in the Demand Curve
  • Change in Quantity Demanded
  • Movement along the demand curve.
  • Caused by a change in the price of the product.

17
Changes in Quantity Demanded
A tax on sellers of ice-cream cones raises the
price of ice-cream cones and results in a
movement along the demand curve.

So you have learned what a price change looks
like now lets look at something else.
  • Shifts in Demand!!!!!!!!!!!!!!!!!! These are when
    people want to buy or not buy a product for any
    other reason besides the price changing!!!!!!!!!!!

QD Vs Change in D
  • To help reveal the difference, I draw a graph
    relating the time that a student spends preparing
    for an exam to his expected grade. It shows that,
    generally speaking, as a student studies more, he
    makes a better grade, i.e., one moves along the
    curve. Now, I ask the students what would happen
    if they somehow came into possession of a copy of
    the exam. They respond, naturally, that they
    would probably be able to make a higher grade
    than before given the same amount of study time.
    In other words, the function shifts.

25
Shifts in the Demand Curve
  • Change in Demand
  • A shift in the demand curve, either to the left
    or right.
  • Caused by any change that alters the quantity
    demanded at every price.

26
This product more people want to buy but not
because the price went down. Look at the price
and Quantities
Notice the price stayed the same

When the curve shifts it is called a Change in
Demand.
  • There are certain things that will make the
    demand curve shift. These are called the
    determinants of demand.

Shifts in the Demand Curve
  • Consumer income
  • Prices of related goods/complimentary and
    substitute goods.
  • Tastes
  • Expectations
  • Number of buyers

29
Expectations
  • College students are often a poor down-trodden
    lot who must pinch pennies to get by and often
    subsist for most of their college careers on
    oatmeal or macaroni and cheese. They have to walk
    around in old rags. (Playing up the poverty of
    students gets sympathetic attention!) They endure
    this extreme deprivation until the last semester
    of their senior year. Then they start to apply
    for jobs and go to interviews. You can easily
    tell who is doing well in the job search process,
    they are the students who go out for pizza and
    beer and who begin to sport flashy new clothes!
    You can also distinguish between majors,
    accounting and computer science majors with high
    expectations will go out for pizza frequently,
    philosophy majors perhaps once or twice! Why does
    this occur? It is because good interviews give
    students confidence that in a few months their
    era of poverty will draw to a close. It is not
    necessary to even receive their first paycheck
    for these students to begin to alter their
    consumption patterns. Most have some slight
    reserve of cash, and the mere expectation of fat
    checks in a few months is enough to loose the
    bands on their coffers. Those without any nest
    egg may be inclined to borrow a bit, knowing that
    repayment will be easy. Budding accountants and
    systems analysts can, of course, be more prodigal
    since the size of the paycheck they anticipate is
    substantially fatter than that expected by the
    average philosophy major. Expectations of the
    future are a broad and powerful demand shifter
    not limited to expectations of future prices of a
    specific good.

30
6 shifts-Determinants of Demand you must memorize
this!!!
  • CTCONSUMER TASTE- What people THINK
  • CI-CONSUMER INCOME- How much money people have
  • SUBSTITUTE GOOD-SG- Good that is bought instead
    of another good-example COKE AND PEPSI
  • COMPLIMENTARY GOOD-CG- Goods that are bought
    together like PB AND JELLY
  • BUYERS-B-The number of potential customers.
    More people more demand and vice versa
  • EXPECTATIONS-E-Anticipation of something
    happening.

Market Demand versus Individual Demand
  • Market demand refers to the sum of all individual
    demands for a particular good or service.
  • Graphically, individual demand curves are summed
    horizontally to obtain the market demand curve.

33
The Market Demand Curve
The market demand at 2.00 will be 7 ice-cream
cones.
When the price is 2.00, Nicholas will demand 3
ice-cream cones.
When the price is 2.00, Catherine will demand 4
ice-cream cones.
The market demand curve is the horizontal sum of
the individual demand curves!

34
Shifts in the Demand Curve
  • Consumer Income
  • As income increases the demand for a normal good
    will increase.
  • As income increases the demand for an inferior
    good will decrease.

Shifts in the Demand Curve
  • Prices of Related Goods
  • When a fall in the price of one good reduces the
    demand for another good, the two goods are called
    substitutes.
  • When a fall in the price of one good increases
    the demand for another good, the two goods are
    called complements.

47
Lets Move on to SUPPLY
  • Supply is always looked at from the
    manufacturer/seller/producer of a product.

48
The curve looks like it goes up!Thus sUPply

49
SUPPLY
  • Quantity supplied is the amount of a good that
    sellers are willing and able to sell.
  • Law of Supply
  • The law of supply states that, other things
    equal, the quantity supplied of a good rises when
    the price of the good rises.

50
The Supply Curve The Relationship between Price
and Quantity Supplied
  • Supply Schedule
  • The supply schedule is a table that shows the
    relationship between the price of the good and
    the quantity supplied.

SUPPLY AND DEMAND TOGETHER
  • Equilibrium refers to a situation in which the
    price has reached the level where quantity
    supplied equals quantity demanded.

91
SUPPLY AND DEMAND TOGETHER
  • Equilibrium Price
  • The price that balances quantity supplied and
    quantity demanded.
  • On a graph, it is the price at which the supply
    and demand curves intersect.
  • Equilibrium Quantity
  • The quantity supplied and the quantity demanded
    at the equilibrium price.
  • On a graph it is the quantity at which the supply
    and demand curves intersect.

  • Draw a supply and demand diagram that shows the
    boss receiving the lions share bliss while
    someone who scrubs floors gets much less. In
    other words, what factors would affect supply and
    demand such that CEOs receive 300 times the
    compensation of average workers? Are CEOs paid
    too much?

97
Equilibrium
  • Surplus
  • When price gt equilibrium price, then quantity
    supplied gt quantity demanded.
  • There is excess supply or a surplus.
  • Suppliers will lower the price to increase sales,
    thereby moving toward equilibrium.

  • Suppliers will raise the price due to too many
    buyers chasing too few goods, thereby moving
    toward equilibrium.

  • Law of supply and demand
  • The claim that the price of any good adjusts to
    bring the quantity supplied and the quantity
    demanded for that good into balance.

Three Steps to Analyzing Changes in Equilibrium
  • Shifts in Curves versus Movements along Curves
  • A shift in the supply curve is called a change in
    supply.
  • A movement along a fixed supply curve is called a
    change in quantity supplied.
  • A shift in the demand curve is called a change in
    demand.
  • A movement along a fixed demand curve is called a
    change in quantity demanded.

Table 4 What Happens to Price and Quantity When
Supply or Demand Shifts?
107
  • Economists use the model of supply and demand to
    analyze competitive markets.
  • In a competitive market, there are many buyers
    and sellers, each of whom has little or no
    influence on the market price.

108
  • The demand curve shows how the quantity of a good
    depends upon the price.
  • According to the law of demand, as the price of a
    good falls, the quantity demanded rises.
    Therefore, the demand curve slopes downward.
  • In addition to price, other determinants of how
    much consumers want to buy include income, the
    prices of complements and substitutes, tastes,
    expectations, and the number of buyers.
  • If one of these factors changes, the demand curve
    shifts.

109
  • The supply curve shows how the quantity of a good
    supplied depends upon the price.
  • According to the law of supply, as the price of a
    good rises, the quantity supplied rises.
    Therefore, the supply curve slopes upward.
  • In addition to price, other determinants of how
    much producers want to sell include input prices,
    technology, expectations, and the number of
    sellers.
  • If one of these factors changes, the supply curve
    shifts.

110
  • Market equilibrium is determined by the
    intersection of the supply and demand curves.
  • At the equilibrium price, the quantity demanded
    equals the quantity supplied.
  • The behavior of buyers and sellers naturally
    drives markets toward their equilibrium.
