Instructions for the Investment Game

You will be given a fixed endowment to decide the following:

(1) How much you are going to invest privately.
(2) How much you are going to invest socially.

The game will last {{ Constants.num_rounds }} rounds. In the 1st round, your endowment will be {{ Constants.endowment }}. In every subsequent round n your endowment will equal to the total payoff from the previous round n-1.

The earnings from the project are calculated as follows:
(1) The private contribution is multiplied by a randomly determined 0.5 < factor < 5 to find out the private earnings. Importantly, the yield for the private investment you have made in this round n will only be available in the next round n+1.

(2) The social contribution entails the following conditions. The contributions of all {{ Constants.players_per_group }} participants are added up, the total contribution is multiplied by a guaranteed factor of {{ Constants.social_multiplier }}, and the resulting amount is the total earnings from the project, which is evenly split among all {{ Constants.players_per_group }} participants. Importantly, the yield for the social investment you have made in this round will be available instantly (i.e. at the end of the current round).

Your total payoff for each round equals the sum of your private and social earnings, plus the amount you did not contribute.
