Demand Demand is not just simply wanting to own a product. Remember, to have demand, you must have: 1.The desire to own it. 2.The ability to pay for it. 3.The willingness to buy it.

Slide 4

What Demand Can Look Like There are two ways to represent demand. One way is through a demand schedule, which you might think of as a demand chart. Another way is through a graph called a demand curve.

Slide 5

Demand Schedule In a demand schedule or demand chart, we simply list the amount of a product that would be demanded at a variety of prices. According to this demand schedule, when the price is $1, the quantity demanded will be 20. When the price rises to $2, only 15 will be demanded. PriceQuantity Demanded $120 $215 $310 $45

Slide 6

Demand Curve We can also represent demand in a graph called a demand curve. The data from the demand schedule is plotted on a graph. Quantity demanded serves as our X coordinate. Price is our Y coordinate. Example: At $1, the quantity demanded is 20. We can then graph the coordinate pair (20, $1)

Law of Demand As you have already figured out, price has an effect on demand. This is known as the Law of Demand. The Law of Demand states that the demand for a product varies inversely with its price. In other words: As price goes up, demand goes down. As price goes down, demand goes up.

Slide 18

Changes in Demand Factors other than price can cause changes in demand These other factors include: 1.Consumers income 2.Consumers tastes 3.Prices of related products (substitute and complements)

Slide 19

Consumers Income Naturally, if your income increases, you will be more able and willing to buy more products at any price. And of course, if your income decreases, you will be less willing and able to buy goods regardless of price.

Slide 20

What would you do? Nike has come out with a new popular line of basketball shoes. Unfortunately, your boss tells you he has to cut back your hours at work so your pay check will be $100 - $200 less this month. Your demand for the new Nike shoes would probably: (Remember, demand is desire, ability, and willingness to buy.) Buy the shoes! Pass on the shoes.

Slide 21

Great choice! Like most consumers, you would cut back on your purchases when your income decreases. That means a decrease in demand. Lets see what else can change demand.

Slide 22

Are you sure? Most consumers recognize that when their income decreases, they should cut back on spending. Losing hours at work means you have less money to spend on necessities like groceries, rent, and bills. The shoes might be great, but you should consider saving your money for more important things.

Slide 23

Consumer Tastes Advertising, trends, and even seasons can affect consumer tastes. Example: Demand for sweaters goes up in the fall and winter. Swimsuits are in higher demand in the spring and summer. Think about Oprahs Book Club. When Oprah picks a new book for her club, what will happen to the demand for that book? It will increase.It will decrease.

Slide 24

Youre correct! Endorsements from celebrities can definitely increase demand! Lets move on!

Slide 25

Sorry! Maybe you dont believe in the power of Oprahs sway, but celebrity endorsements DO create an increase in demand for a product.

Slide 26

Substitutes Substitutes are product that can be used in place of another. Example: Margarine can be substituted for butter. Increase in the price of one good can cause an increase in demand for a cheaper substitute.

Slide 27

Complements Complements are goods that go together. Example: Hot dogs and buns. Decreasing the price of one good increases the demand for its complement.

Slide 28
