Your Task

This task has {{ C.NUM_PAYMENT_ROUNDS }} rounds.
Every round, you and other participants (1) make a choice and (2) guess the choices of other participants. Your choice and guess will determine how likely you are to get a bonus of {{ player.session.config.currency_symbol }}{{ player.session.config.bonus | to2 }}.
At the end of the task, you will be paid the participation fee of {{ player.session.config.currency_symbol }}{{ player.session.config.participation_payment | to2 }} and one round will be chosen randomly to determine your chance of getting the bonus.

In each round, you will be randomly matched with another participant (your opponent). Both you and your opponent must choose between an asset (Option A) and the assigned baseline points (Option B).

• Option A: You receive the asset's value if your opponent chooses Option B. If both you and your opponent choose Option A, both of you receive 0 points.
• Option B: You receive your assigned baseline points, regardless of what your opponent chooses.

Key Details

• Asset's Value: The asset is worth the same amount of points for both you and your opponent.
• Baseline Points: At the start of each round, every participant is assigned a random number of baseline points between 0 and 100. All values are equally likely and have been randomised for each participant.
  You will not know your opponent's baseline points and your opponent will not know your baseline points.
• Same Incentives for Everyone: Everyone else in the task follows these same rules and has the same incentives as you.
• Independence: The asset value, your baseline points, and your opponent's baseline points vary each round. Your choices across rounds are independent and do not affect one another.

Example

Suppose the asset (Option A) is worth 50 points and your baseline points (Option B) are 38.4.

• If you choose Option B, you are guaranteed to receive your baseline points of 38.4.
• If you choose Option A and your opponent chooses Option B, you receive the asset value of 50.
• If both you and your opponent choose Option A, both of you receive 0 points.

Guesses

In addition, we will ask you what you believe other participants will do. The more accurate your guess is, the more likely you are to get the bonus.

Bonus Payment Rule

Your choice and guess will determine how likely you are to get the bonus. The payment rule is designed so that (1) you choose to maximise what your points given how likely you think others are to invest or not; (2) you tell us what you believe the probability is that your opponent chooses each action.
To ensure this, your payment from guesses is determined as follows:

• At the end of the study, one round will be randomly selected, and either your choice or your guess is chosen to determine payment, both equally likely.
• If your choice is selected for payment, then the probability you get the bonus equals the number of points you got from your choice, as described above.
• If your guess is selected for payment, we draw two random choices according to your guess. You get 50 points for each choice that matches the choice of your opponent. In addition, you get 50 points if the two drawn choices are different. The probability you get the bonus equals the resulting total number of points.

Practice Rounds

In order to get familiarised with the task, you will begin with {{ C.NUM_PRACTICE_ROUNDS }} practice rounds. The practice rounds do not count toward your chance of getting the bonus.
There is also a brief questionnaire at the end.
