1  Your favorite team is in the Super Bowl:  1. How many tickets are available?  2. How many people want tickets?  3. What determines the price of a ticket?

2  Demand: The desire to own something and the ability to pay for it.  Law of Demand: As the price of a good increases, quantity demanded decreases (and vice versa)  In other words: when price goes up, we buy less…when price goes down, we buy more

3  1. The Substitution Effect. occurs when consumers react to an increase in a good’s price by consuming less of that good… and more of other goods that satisfy the same basic need. OR

4  2. The Income Effect: The quantity of an item you consume changes if its price changes but your income does not.

5  Demand Schedule: a table that lists the quantity of a good that a person will purchase at each price in the market.  Market Demand Schedule: a table that lists the quantity of a good all consumers in a market will buy at each different price.

7  Assuming I get my candy for free, if the following market demand schedule is true, how much should I charge for M&M’s? Why? Market Demand Schedule for M&M's: Price of M&M'sQuantity Demanded/Day A.$2100 B.$1200 C.$ D.$

8 Market Demand Schedule for M&M's: Price of M&M'sQuantity Demanded/DayProfit A.$2100 $200 B.$1200 $200 C.$ $250 D.$ $175

9  Demand Schedule: a table that lists the quantity of a good that a person will purchase at each price in the market.  Market Demand Schedule: a table that lists the quantity of a good all consumers in a market will buy at each different price.

10  So what is a demand curve?  Very Simple, a demand curve is just a graphical representation of a demand schedule.

12 1. Complements: Products that you would purchase together. (Ex, Chips and Salsa). 2. Substitutes: Products that are similar. You would buy the other if the price of one got too high (Ex: Coke and Pepsi).

13 3. Normal Good: A product that you buy more of as your income goes up. (EX: Cars, clothes, Xbox games, almost everything. 4. Inferior Good: A product you buy less of as income increases. (EX: Ramen Noodles, Mac & Cheese

15  Can only be used to predict how people’s buying habits might change when price and ONLY price changes  When price changes, it is called a movement along the demand curve or a change in quantity demanded (there’s no way to simply remember this…you must memorize! Sorry.)

16  Horizontal axis shows quantity  Vertical axis shows price  Let’s talk about horizontal, vertical, and quantity.

17 Remember this market demand schedule for pizza? Market Demand Schedule: Price of Pizza Slice Quantiy Demanded/day $ $ $ $ $ $

18  IMPORTANT: That demand schedule shows what happens to the quantity of pizza demanded when price, and ONLY price changes.  But there are other things that can cause the ENTIRE demand curve to shift.

19  Causes of a change in demand:  1. Income (if we make more $, we will demand more of a good at any price. The opposite is also true!).  2. Consumer expectations (If we expect prices to rise in the future, we’ll be more likely to spend more $ now. If we expect a sale, we will be less likely to spend more now).

20  3. Consumer tastes and advertising (Think about it…why do companies use celebrities to promote their products?).  4. Population (If population goes up…so does demand. Think baby boomer gen.).  5. Prices of related goods (substitutes and compliments). (If the price of tortilla chips increases, what will happen to the demand for salsa?).

22  What is the difference between a “ change in quantity demanded” and a “change in demand” ?  Change in Quantity Demanded: a movement along the demand curve caused by a change in price

23  Change in Demand: A shift in the demand curve due to factors other than price. Basically it shows that demand has changed at all different price levels.  Put a star next to this point in your notes.
