Phase 2: Sender-Receiver Game

This game has two players: a sender and a receiver. You will play this game twice, once as the sender and once as the receiver. Each time, both the sender and the receiver will begin with {{ Constants.endowment }} in their account. You will be randomly partnered with a different participant each time. Neither you nor your partners will ever learn the identity of the other.

Sender Phase:

As a sender, you must decide how much of their {{ Constants.endowment }} endowment you want to transfer to the receiver you are matched with. You may transfer between 0 to {{ Constants.endowment }}, which will be tripled and placed in the Receiver’s account. For example, if you transfer 2 tokens, then 6 tokens will be added to the Receiver’s account. You will have 8 tokens in your account, and the Receiver will have 6 tokens in theirs.

Receiver Phase:

The receiver’s decision depends on how many tokens the sender transferred into their account. You will be shown how much your account has increased, and then make your decision. You can transfer from your account, back to the sender, any amount from 0 up to the total number of tokens in your account. For example, if the sender transfers 2 tokens, then the receiver’s account now has 10 + 3 x 2 = 16 tokens. The Receiver can then choose to transfer between 0 and 16 tokens back to the sender. The receiver will keep whatever remains in their account.

Example 1:

In the Sender Phase, you choose to transfer 2 of your 10 tokens to the person you are randomly matched with.
The person you are randomly matched with sees in the Receiver Phase that they were sent 3, which is multiplied by 3 so that they have 9 tokens in their account. They choose to transfer 4 back to your account.
At the end of this round, you have 10 – 3 + 4 = 11 tokens. The receiver you were matched with has 10 + 9 – 4 = 15.

Example 2:

In the Receiver Phase you find out that the sender you are randomly matched with chose to transfer 5 tokens. This 5 is multiplied by 3 so that you have 10 + 15 = 25 tokens in your account. You choose to transfer 6 back to the Sender.
At the end of this round, your private account has 10 + 15 – 6 = 19 tokens. The sender you were matched has 10 – 5 + 6 = 11.

Quiz 2:
You will receive 2 tokens for each complete correct answer to the following questions, paid separately at the end of the experiment.
1. In the first phase, as a Sender, you chose to transfer 6 tokens. The Receiver’s account increases by: {{ formfield 'answer_1' }} The Receiver chooses to transfer 8 back to you. Now, the amount in your account is: {{formfield 'answer_2' }} The amount in the Receiver’s account is: {{formfield 'answer_3' }}

2. As a Receiver, the Sender matched with you transferred 7 tokens to your account. Your account increases by: {{formfield 'answer_4' }} You now have in your account: {{formfield 'answer_5' }}

3. You choose to transfer 11 tokens back to the Sender’s account. The Sender now has in their account: {{formfield 'answer_6' }} You now have in your account: {{formfield 'answer_7' }}

4. At the end of this round, your earnings for this round are: {{formfield 'answer_8' }}. {% next_button %} {% endblock %}
