Law of Demand

 MARKET ECONOMY
Demand

 When you buy something, why do you think it sells
  at that particular price?
 All consumers (you and me) individually and
  collectively have a great influence on the price of all
  goods and services.
 Demand: the amount of good or service that
  consumers are able and willing to buy
The Market

 A Market represents the freely chosen actions
  between buyers and sellers of goods and services.
 In a market economy, individuals (buyers and
  Sellers) decide for themselves the answers to the
  WHAT? HOW? WHOM? Economic questions.
“The Law of Demand”

 In order for something to sell, two things need to
 happen
    A) A buyer needs to be able to buy something
    B) A buyer needs to be willing to buy something
 BOTH have to happen, or the Demand for that item
  does not exist
 The Law of Demand states:
    As price goes up, quantity demanded goes down
    As price goes down, quantity demanded goes up
Three Economic Rules that Effect Quantity
             Demanded and Price

 Rule #1. Real income effect
 Rule #2. Substitution effect
 Rule #3. Diminishing Marginal Utility
Real Income Effect

 Individuals cannot keep buying the same quantity of
 a product if its price rises while their income stays
 the same.
Substitution Effect

 If two items satisfy the same need, and the price of
 one rises.. People will buy the other.
Diminishing Marginal Utility

 Utility is the power that any good or service has to
  satisfy your wants.
 Based on utility, people decide what to buy and how
  much they are willing and able to pay.
 When you buy something you decide the amount of
  satisfaction, or use, you think you will get from a
  good or service.
 However Diminishing Marginal Utility states that
  the additional satisfaction a consumer gets from
  purchasing one or more unit of a product will lessen
  with each additional unit purchased.
