The Roles

In this task three participants are randomly matched in a group. These are real participants also recruited on Prolific. Their identity will remain anonymous to one another. The three participants are randomly assigned one of three possible roles: Player A, Player B or Player C.

Player A and B are each asked to make a choice that will affect the earnings of all three participants in the group. Player C has no choice to make.

{% if player.id_in_group == 1 %} You are assigned to the role of Player A. {% elif player.id_in_group == 2 %} You are assigned to the role of Player B. {% endif %}

The "Choose-a-Project" Task

In this task there are two types of projects that Player B has to choose from:

  • A Communal Project that pays £8 to each of the three players
  • An Exclusive Project between {% if group.random_game == 1 %} Player B and C that pays £12 to Player B and Player C and £6 to Player A. {% else %} Player A and B that pays £12 to Player A and Player B and £{{ Constants.excluded_payoff }} to Player C. {% endif %}
{% if Constants.excluded_payoff == 6 %} {% else %} {% endif %}
Player A can impose a fee

Before Player B chooses between the Communal Project and Exclusive Project, Player A decides whether to impose a fee against Player B for choosing the Exclusive Project.

If Player A imposes the fee, the earnings of {% if Constants.other_NS %} Player B is {% else %} each player who is part of the Exclusive Project are {% endif %} reduced by £2. The figure below illustrates the possible earnings depending on Player A's decision.

{% if Constants.excluded_payoff == 6 and not Constants.other_NS %} {% elif Constants.excluded_payoff == 10 %} {% elif Constants.other_NS %} {% endif %}
Player B chooses a project

After learning whether Player A has imposed a fee, Player B chooses between the Communal Project and the {% if group.random_game == 1 %} Exclusive Project between Player B and C. {% else %} Exclusive Project between Player A and B. {% endif %}

{% if Constants.excluded_payoff == 6 and not Constants.other_NS %} {% elif Constants.excluded_payoff == 10 %} {% elif Constants.other_NS %} {% endif %}

Before proceeding to the next screen, please answer the following comprehension questions. You may navigate between the tabs to review the instructions.
