日本語The game consists of two stages:
日本語In the beginning of the first stage each round every participant in your group of {{ Constants.players_per_group }} receives {{ Constants.endowment|c }}. The group has the opportunity to undertake a joint project. Each participant in the group decides how much she or he is going to contribute to the project. Contribution could be any integer from 0 to {{ Constants.endowment|c }}.
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.
