In the beginning of each round every participant in your group
of {{ Constants.players_per_group }}
receives
{% if subsession.hetero_endowment %}
an endowment that varies between {{ Constants.lb }} and {{ Constants.ub }}.
{% else %}
{{ Constants.endowment|c }}.
{% endif %}
The group
has the opportunity to undertake a joint project. Each participant in
the group decides how much they are going to contribute to
the project. Contribution could be any integer from {{ 0|c }}
to {% if subsession.hetero_endowment %}
the amount this person received as an endowment.
{% else %}
{{ Constants.endowment|c }}.
{% endif %}
The earnings from the project are calculated as follows: The
contributions of all {{ Constants.players_per_group }} participants are
added up, the total contribution
is multiplied by a factor of {{ Constants.efficiency_factor }}, and the
resulting amount is the total earnings from the project, which is
evenly split among all {{ Constants.players_per_group }}
participants. Your payoff equals your earnings from the project, plus
the amount you did not contribute.
