We first introduce you to the basic decision situation. Then, you will complete a pre-study questionnaire on the screen in front of you, which is intended to help you understand the decision situation.


You are in a group composed by 4 members.

{% if player.treatment == "equalpro" %}


In each group, every member has to decide the allocation of 20 tokens. You can put these 20 tokens into your private account or you can put some or all of them into a project. The other three members of your group have to make the same decision.

{% elif player.treatment == "equalmain" %}


In each group, there are 80 tokens in a project. You can withdraw up to 20 tokens from the project and put them into your private account or you can leave them fully or partially in the project. The other three members of your group have to make the same decision.

{% elif player.treatment == "unequalpro" %}


In each group, two members will be allocated 10 tokens and the other two will be allocated 30 tokens. How many tokens each group member will be allocated will be randomly determined by the computer. You can put these 10 or 30 tokens into your private account or you can put some or all of them into a project. The other three members of your group have to make the same decision.

{% elif player.treatment == "unequalmain" %}


In each group, there are 80 tokens in a project. Two members can withdraw up to 10 tokens from the project and the other two up to 30 tokens. How many tokens each group member can withdraw will be randomly determined by the computer. You can withdraw up to 10 or 30 tokens from the project and put them into your private account or you can leave them fully or partially in the project. The other three members of your group have to make the same decision.

{% endif %}

Your income from the private account

{% if player.treatment == "equalpro" or player.treatment == "equalmain" %}


You will earn 1 point for each token you put into your private account. For example, if you put all 20 tokens into your private account, your income from your private account would be 20 points. If you put 6 tokens into your private account, your income from this account would be 6 points. No one except you earns anything from tokens you put in your private account.

{% elif player.treatment == "unequalpro" or player.treatment == "unequalmain" %}


You will earn 1 point for each token you put into your private account. For example, if you put all 10 or 30 tokens into your private account, your income from your private account would be 10 or 30 points, respectively. If you put 6 tokens into your private account, your income from this account would be 6 points. No one except you earns anything from tokens you put in your private account..

{% endif %}

Your income from the project

{% if player.treatment == "equalpro" or player.treatment == "unequalpro" %}


Each group member will profit equally from the amount you or any other group member put into the project. The income for each group member from the project will be determined as follows:

Income from the project = 0.4 × (sum of contributions)


If, for example, the sum of all contributions to the project is 60 tokens, then you and each other member of your group would earn 60 × 0.4 = 24 points out of the project. If the four members of the group contribute a total of 10 tokens to the project, you and the other members of your group would each earn 10 × 0.4 = 4 points.

{% elif player.treatment == "equalmain" or player.treatment == "unequalmain" %}


Each group member will profit equally from the amount you or any other group member leave in the project. The income for each group member from the project will be determined as follows:

Income from the project = 0.4 × (80 - sum of all tokens withdrawn from the project)


If, for example, the sum of all tokens withdrawn from the project by you and your other group members is 20 tokens, then you and each other member of your group would earn (80-20) × 0.4 = 24 points out of the project. If the four members of the group withdraw a total of 70 tokens from the project, you and the other members of your group would each earn (80-70) × 0.4 = 4 points.

{% endif %}

Total income


Your total income is the sum of your income from your private account and from the project:

{% if player.treatment == "equalpro" %}

Your Total Income = Income from your private account + Income from the project =20 – your contribution to the project + 0.4 × sum of all contributions to the project

{% elif player.treatment == "equalmain" %}

Your Total Income = Income from your private account + Income from the project =Tokens withdrawn from the project by you + 0.4 × (80-sum of all tokens withdrawn from the project)

{% elif player.treatment == "unequalpro" %}


If you are randomly allocated 10 tokens:

Your Total Income = Income from your private account + Income from the project =10 – your contribution to the project + 0.4 × sum of all contributions to the project


If you are randomly allocated 30 tokens:

Your Total Income = Income from your private account + Income from the project =30 – your contribution to the project + 0.4 × sum of all contributions to the project

{% elif player.treatment == "unequalmain" %}

Your Total Income = Income from your private account + Income from the project =Tokens withdrawn from the project by you + 0.4 × (80-sum of all tokens withdrawn from the project)
