Each firm in the market sells the exact same course notes for a difficult course. Each semester, each firm in the market simultaneously chooses its price. You choose a price by selecting a number, and then pressing the Set Price button.
If firm 1 chooses $9 and firm 2 chooses $10:
|Payoff||=||items sold||x||(price - cost)|
|Firm 1||=||1800||x||($9 - $2)||=||$12,600|
|Firm 2||=||0||x||($10 - $2)||=||$0|
