You are not the leader, thus your payoff is
$$ \left(\text{(endowment - contribution)} + {{ Constants.eff_factor }} \times \text{the sum of contributions to the group account} \right) \times \frac{10 - \text{leader's punishment}}{10} $$
As a reminder, the leader has the ability to punish the group, on a scale of 1-10 points.
The punishment of the group will result in a lower payoff for every member of the group.
Your endowment is {{ Constants.endowment }}. How much do you want to contribute?
