Situation Description

Suppose that in a decision-making experiment individuals will participate in a task with two stages. At each stage, they can be assigned to the role of Individual A or to the role of Individual B with some probabilities specified below. Suppose that, at each stage, Individual A is randomly paired with another Individual B. The pairing is anonymous, meaning that neither individual will ever know the identity of the other individual with whom he or she is paired. In the first stage, each participant is equally likely to be Individual A or Individual B, meaning that each participant had a 50% chance to be assigned to any of the two roles.

In each stage, Individual A will make a choice. The experimenter will record this choice. Individual B will NOT observe the choice of Individual A until the end of the experiment. Both individuals will be paid money based on the choices made by Individual A, and a small participation fee. Suppose that neither individual will receive any other money for participating in the experiment.

In each pair, Individual A receives $10. Individual A will then have the opportunity to give any amount of his or her $10 to Individual B. That is, Individual A can give any of the $10 he or she receives to Individual B. The amount that Individual A gives to Individual B is DOUBLED by the experimenter. This means that if Individual A gives x$ to Individual B, Individual B will receive 2*x$. This choice will determine how much money each participant will receive in this stage.

{% if treatment == 'FullMobility' %}

At the second stage, each participant will be paired with a DIFFERENT participant of the experiment. At the second stage, each participant will have the OTHER role he or she had in the first stage. This means that the participants that were Individual A, in the first stage, will be Individual B in the second stage. The participants that were Individual B, in the first stage, will be Individual A in the second stage. At the second stage, participants face the same decision as at the first period. Participants that are assigned as Individual A receive 10$, and they have to decide the amount they want to give to a participant that are assigned as Individual B. As in the first stage, the amount given by Individual A is doubled by the Experimenter. After the second stage the experiment concludes.

{% elif treatment == 'IntermediateMobility' %}

At the second stage, each participant will be paired with a DIFFERENT participant of the experiment. At the second stage, each participant will have the SAME probability to be Individual A and Individual B. This means that the participants that were Individual A, in the first stage, will have 50% chance to be Individual A, and 50% chance to be Individual B in the second stage. The participants that were Individual B, in the first stage, will have 50% chance to be Individual A, and 50% chance to be Individual B in the second stage . At the second stage, participants face the same decision as at the first period. Participants that are assigned as Individual A receive 10$, and they have to decide the amount they want to give to a participant that are assigned as Individual B. As in the first stage, the amount given by Individual A is doubled by the Experimenter. After the second stage the experiment concludes.

{% elif treatment == 'WithoutMobility' %}

At the second stage, each participant will be paired with a DIFFERENT participant of the experiment. At the second stage, each participant will have the SAME role he or she had in the first stage. This means that the participants that were Individual A, in the first stage, will be Individual A in the second stage. The participants that were Individual B, in the first stage, will be Individual B in the second stage. At the second stage, participants face the same decision as at the first period. Participants that are assigned as Individual A receive 10$, and they have to decide the amount they want to give to a participant that are assigned as Individual B. As in the first stage, the amount given by Individual A is doubled by the Experimenter. After the second stage the experiment concludes.

{% endif %}

The participants will be paid at the end of the experiment the money received at one of the two stages (plus the participation fee). The selected stage will be randomly determined with EQUAL probability at the end of the experiment.
