The interaction

In this study, you will be in a randomly formed group of {{ Constants.players_per_group }} participants.

Every round you will be given {{ Constants.endowment }}.

Each participant in the group decides how much she or he is going to contribute to a common project.

Contributions could be either 0 or {{ Constants.endowment }}.

The decisions will be made sequentially. The computer will assign roles to each participants in the group. For example, if you are player 1 you will make your decision first, then player 2 will make his/her decision, then player 3 and so on. Your role will be randomly determined each round. You will not be informed about your role.

Before you make your decision, you will be informed about the total contribution made by your 2 immediate predecessors , but not individual contributions. This means you will be informed about total contribution of the 2 players who played before you. For example, if your screen shows "Your 2 immediate predecessor have contributed 100", it means one of the two players who played before you contributed 100 and the other contributed 0.

Only Player 1 in each round will not receive any information as he is the first player to make a decision.

Player 2 will receive information about only one predecessor.

Your payoff
