You have been allocated 20 tokens and the other group member has been allocated 20 tokens..
Example 1: Suppose that both members of the group contribute 0 tokens to the project. Both group members will receive
an “income from tokens kept” of 20. Nobody receives anything from the project, because no one contributed anything.
Therefore, the total income of every member of the group is 20 points.
Calculation of your bonus amount: (20 – 0) + 0.75 x (0) = 20 points
Example 2: If you contribute 0 tokens and the other member contributes 10 tokens. Because you and the other member
have together contributed 10 tokens, everyone will receive 0.75 x 10 = 7.5 points from the project. You contributed
0 tokens to the project. You will therefore receive 27.5 points in total at the end of the experiment.
Calculation of your bonus amount: (20 – 0) + 0.75 x (10) = 27.5 points.
Example 3: If you contribute 15 tokens and the other member contributes 5 tokens. Because you and the other member
have together contributed 20 tokens, everyone will receive 0.75 x 20 = 15 points from the project. You contributed
15 tokens to the project. You will therefore receive 20 points in total at the end of the experiment.
Calculation of your bonus amount: (20 – 15) + 0.75 x (20) = 20 points.
Example 4: If you contribute 20 tokens and the other member contributes 0 tokens. Because you and the other member
have together contributed 20 tokens, everyone will receive 0.75 x 20 = 15 points from the project. You contributed
20 tokens to the project. You will therefore receive 15 points in total at the end of the experiment.
Calculation of your bonus amount: (20 – 20) + 0.75 x (20) = 15 points.
{% elif player.your_type == "low"%}
You have been allocated 10 tokens and the other group member has been allocated 30 tokens.
Example 1: Suppose that both members of the group contribute 0 tokens to the project. Because you and the other
member have together contributed 0 tokens, everyone will receive 0 points from the project. You contributed 0
tokens to the project. You will therefore receive 10 points in total at the end of the experiment.
Calculation of your bonus amount: (10 – 0) + 0.75 x (0) = 10 points.
Example 2: If you contribute 0 tokens and the other member contributes 10 tokens. Because you and the other member
have together contributed 10 tokens, everyone will receive 0.75 x 10 = 7.5 points from the project. You contributed
0 tokens to the project. You will therefore receive 17.5 points in total at the end of the experiment.
Calculation of your bonus amount: (10 – 0) + 0.75 x (10) = 17.5 points.
Example 3: If you contribute 5 tokens and the other member contributes 25 tokens. Because you and the other member
have together contributed 30 tokens, everyone will receive 0.75 x 30 = 22.5 points from the project. You
contributed 5 tokens to the project. You will therefore receive 27.5 points in total at the end of the experiment.
Calculation of your bonus amount: (10 – 5) + 0.75 x (30) = 27.5 points.
Example 4: If you contribute 10 tokens and the other member contributes 0 tokens. Because you and the other member
have together contributed 10 tokens, everyone will receive 0.75 x 10 = 7.5 points from the project. You contributed
10 tokens to the project. You will therefore receive 7.5 points in total at the end of the experiment.
Calculation of your bonus amount: (10 – 10) + 0.75 x (10) = 7.5 points.
{%else%}
You have been allocated 30 tokens and the other group member has been allocated 10 tokens.
Example 1: Suppose that both members of the group contribute 0 tokens to the project. Because you and the other member
have together contributed 0 tokens, everyone will receive 0 points from the project. You contributed 0 tokens to
the project. You will therefore receive 30 points in total at the end of the experiment.
Calculation of your bonus amount: (30 – 0) + 0.75 x (0) = 30 points.
Example 2: If you contribute 0 tokens and the other member contributes 10 tokens. Because you and the other member
have together contributed 10 tokens, everyone will receive 0.75 x 10 = 7.5 points from the project. You contributed
0 tokens to the project. You will therefore receive 37.5 points in total at the end of the experiment.
Calculation of your bonus amount: (30 – 0) + 0.75 x (10) = 37.5 points
Example 3: If you contribute 25 tokens and the other member contributes 5 tokens. Because you and the other member
have together contributed 30 tokens, everyone will receive 0.75 x 30 = 22.5 points from the project. You
contributed 25 tokens to the project. You will therefore receive 27.5 points in total at the end of the experiment.
Calculation of your bonus amount: (30 – 25) + 0.75 x (30) = 27.5 points.
Example 4: If you contribute 30 tokens and the other member contributes 0 tokens. Because you and the other member
have together contributed 30 tokens, everyone will receive 0.75 x 30 = 22.5 points from the project. You
contributed 30 tokens to the project. You will therefore receive 22.5 points in total at the end of the experiment.
Calculation of your bonus amount: (30 – 30) + 0.75 x (30) = 22.5 points.
