1. A Market in Crude Oil
Let’s Play a Game!

2. Each of you will be either a
BUYER
SELLER

3. Keep track of your progress for each transaction.
Gain/Loss
Keep track of your progress for each transaction.
Record the price on your card each time you get one (A)
After you make a sale/purchase, record that price (B)
At the end of each round, calculate the gain or loss for each transaction.
Sellers make a gain when they sell for more than the price on their Sell Card.
Buyers gain when they pay less than the price on their Buy Card.

6. Reaching the Market Clearing Price through Supply & Demand
Market Equilibrium
Reaching the Market Clearing Price through Supply & Demand

8. What is Equilibrium?
Price where the quantity supplied and the quantity demanded are equal
On the graph: where the curves intersect
AKA:
the Market Clearing Price

9. The Role of Prices
Prices act as signals to buyers and sellers

10. Role of Prices
Prices send signals and provide incentives to buyers and sellers.
signal to producers about what to produce
Signal to consumers about how much to buy

11. Role of Prices
When supply and demand changes, market prices adjust, affecting incentives.
Buyers and Sellers respond in predictable ways to a change in prices
Higher prices induce extra production while they discourage consumption.
Prices are the motivator in a market economy while competition is the regulator, keeping prices in equilibrium.

12. EQUILIBRIUM
Market condition that exists when quantity demanded is equal to quantity supplied.
Markets always move toward this.
Think of it as the market’s “happy place”

13. SHORTAGE
Market condition that exists when quantity demanded is greater than quantity supplied.
Think of it as the market’s “Unhappy place”

15. SURPLUS
Market condition that exists when quantity SUPPLIED is greater than quantity demanded.
Think of it as the market’s “Unhappy place”

18. Let’s Graph It!
How to find equilibrium on a curve

19. MARKET EQUILIBRIUM
The market equilibrium price is:
Quantity Demanded is
Quantity Supplied is
Quantity P R I C E S D 10 15 20 5 25

If someone set a price of $5 for T-shirts:
Quantity Demanded: ______
Quantity Supplied: ______
This would result in a (surplus / shortage) of t-shirts.
If someone set a price of $20 for T-shirts:
Quantity Demanded: _____
Quantity Supplied: _____
This would result in a (surplus / shortage) of t-shirts.

Connecticut ships its apples to all parts of the country by rail
A hurricane destroys the apple crops in Connecticut before they are picked
How would this effect each of the commodities below?

35. S1
Supply of apples was lost in Connecticut and not as many were shipped to Boston D1
Washington farmers would want more land to grow more apples since apples were destroyed in Connecticut = more profit for them

36. D1
People would want apples from Washington since they can’t get them from Connecticut D1
People would want more pears (since it is a substitute for apples)

37. S1
Less apples to buy means less apple pies in the market (need apples to make the pies)
