Instructions

You are about to participate in a decision task. For this task, you will be randomly paired with another participant from this study. Note that you will not know, now or later, who the other participant is. One of you will be selected at random to be Participant A, and the other will be Participant B. You will learn whether you are Participant A or B prior to making any decisions.

This study includes several decision rounds. At the start of each round, Participant A will receive 200 points. Participant A will then choose how many of their 200 points to send to Participant B (any integer amount between 0 and 200 points is possible). Participant A will keep any amount not sent to Participant B.

Before Participant B receives this amount, it will be tripled by the experimenter, so that Participant B receives 3 times the points sent by Participant A. Then, Participant B can decide to send back some or all of the amount received back to Participant A. The amount sent back will not be tripled.

To summarize, Participant A's payoff will be composed of any points kept of the initial 200, plus any points sent back from Participant B. Participant B's payoff will be the tripled amount sent from Participant A, minus the amount sent back to Participant A. This process will repeat for several rounds.

Before any of the decision rounds, Participant A will choose a "level of transparency". The level of transparency denotes the probability that Participant A will be informed about the amount sent back by Participant B. There are three levels of transparency for Participant A to choose from: 0%, 10% 50%, and 100%. The level of transparency chosen by Participant A will be conveyed to Participant B before the decision task starts, and it will be applied to every decision round.

If Participant A chooses 0%, they will not find out how much Participant B sent back until the end of all rounds and the study is concluded.

If Participant A chooses 10%, they will find out how much Participant B sent back with a probability of 10%.

If Participant A chooses 50%, they will find out how much Participant B sent back with a probability of 50%, that is, half the time.

If Participant A chooses 100%, they will find out how much Participant B sent back in every round.

At the end of the study, the points will be converted into real money at the rate of 100 points = US$1. You will earn US$1 for completing the experiment. Additionally, one of your decision rounds will be chosen at random, and you will receive a bonus payoff in US$ equal to the amount of points you earned in that round.

Remember that you will be paid for real, so consider your decisions carefully.
