Strategic thinking

Regarding the practice of oligopoly and collusion:

There was a game in class.

Please see the attached image.

There were 9 teams, and our team participated in the game.

As a result, 5 groups participated, and each team got 6 points.

How can I answer the following questions? 1 To what extent do generally people make their decision based on the incentives of the experiment? 2 How can I explain my decision to participate or not as a cost-benefit analysis: what were the real costs and what were the real benefits?

3 What was my opportunity cost? Is that not participating and not getting any points? 4 Did I anticipate what others could do? I anticipated that all the teams would join.

5 How does the number of groups participating affect my decision?

6 How my decision to participate or not would change if the extra points were doubled or half?

7. Is it easy to collude in the game ?

8. What if the prize of successful collusion had been 1 extra point only?

9 How does usually the number of groups participating affect our decision? (i.e. if the # groups was higher (say double) or lower (say half)
