1. Competition in a market economy
What is it?

2. Introductory activity pt. 1 Donut shop!
Examine the case study of two donut shops on p and complete the following chart:
After completing the chart, answer the following questions:
How has competition between the two shops affect the variety of & price of donuts available to you?
Explain how you think competition has affected the decision the shops have made about ingredients? How has it affected labour?
Automatic Donuts
Bakers Dozen Donuts
Price
Variety
Quality

3. Introductory activity pt. 2 Other examples
Please think of an example of competition you see in Calgary & compare the two:
Explain how you think competition has affected the decisions the shops have made about ingredients? Labour?
How might the decisions of these companies affected your friends? Family?
Company A
Company B
Product
Price
Variety
Quality

4. How does Competition affect price, S & D?
An illustrated example

5. A tale of two muffins
To illustrate the balance between price, supply, and demand, I will use two bakeries as an example. For easier understanding, the texts are color-coded, red for anything that relates to store “R” and blue if it’s related to store “B”

6. All three elements (P, S, D) are in balance; In a state of Equilibrium
Assume: these two stores are the only two stores this community has access to. the quality is exactly the same.
Store “R”
Store “B”
Price  Demand  Supply
All three elements (P, S, D) are in balance; In a state of Equilibrium
= $1.50
$1.50 =
Customers =

7. < = Store “R” Store “B” = $1.50 = $2.25 $1.50 = Customers
One day, store “R” owner decides to raise the price of the muffins to make more profit.
Store “R”
Store “B”  
Price  Demand  Supply 
Since the price of the muffin went up, customers who usually buy from store “R” decides to purchase from store “B” instead; leaving store “R” with lots of muffins left over.
= $1.50
= $2.25
$1.50 =
Customers
< =

8. Since the store “R”s price drops, the demand for the muffins increase.
Since store “B” has way more customers than before, the supply of the muffins go down and because of that, the store “B owner raises the price. 
Store “R”
Store “B”
Supply  Price  Demand  
On the other hand, the store “R” owner lowers the price of the muffins since less people purchase it and there are lots of muffins left over.
Since the store “R”s price drops, the demand for the muffins increase.  
Supply  Price  Demand 
= $2.25
= $1.75
$2.00 =
$1.50 =
Customers
<

9. Since the store “B”s price drops, the demand for the muffins increase.
Since store “R” has way more customers than before, the supply of the muffins go down and because of that, the store “R” owner raises the price.  
Store “R”
Store “B”
Demand  Supply  Price 
On the other hand, the store “B” owner lowers the price of the muffins since less people purchase it and there are lots of muffins left over.
Since the store “B”s price drops, the demand for the muffins increase. 
Demand  Supply  Price  
$2.00 =
$1.50 =

10. You might have noticed a pattern in the past few slides.

11. This cycle: 1.  
Price  Demand  Supply  2.  
Supply  Price  Demand 3.   
Demand  Supply  Price  4.  
Price Demand  Supply 
This pattern cycles through many times but the difference slowly gets smaller and smaller every time, until the equilibrium is restored.

12. Kind of like a swing
Imagine the center of the swing as the equilibrium. The swing will go back and forth, but eventually, it will come to a stop at the centre.

13. Same with economy. Price, demand, and supply will eventually get back in balance, restoring equilibrium.

14. Monopolies vs Supply and Demand

15. Monopoly vs competition
So, we have explored how Competition between companies can affect Market (and mixed) Economies via Supply and Demand
But what about Monopolies?

16. Key terms
MONOPOLY: A monopoly is any business that is the sole producer or distributer of a good or service
Consider the Board Game. How do you win Monopoly?

17. Monopolies – good or bad??
What could be some possible problems with having Monopolies?
What could be benefits of having Monopolies?

18. Monopolies

19. Monopoly vs competition
Read Pg. 213 in Textbook then answer the following questions
Why would the government want to support Monopolies?
Why would it want to stop them?
How do government decisions about competition and monopolies reflect a societies values?
