Summary:

1. Die roll phase

{{ Constants.roles.0 }} clicks on the die symbol, the program simulates a {{ Constants.dice.1 }}-sided die, and shows {{ Constants.roles.0 }} the result.
The result of the die roll has to the reported.
The result is either reported by {{ Constants.roles.0 }} or automatically by the program. How it is reported, automatically or by {{ Constants.roles.0 }}, will be told to {{ Constants.roles.0 }} and {{ Constants.roles.1 }} before the interaction.
The reported value is {{ Constants.roles.0 }}’s balance. {{ Constants.roles.1 }} will never know the die roll or the report made by {{ Constants.roles.0 }}.

2. Trading phase:

{{ Constants.roles.1 }} has a fictional object that {{ Constants.roles.0 }} can sell to {{ Constants.roles.1 }}.
{{ Constants.roles.0 }} can only use the balance from the die roll phase to buy the object
If {{ Constants.roles.0 }} buys the object, {{ Constants.roles.0 }} earns 12 points.
For {{ Constants.roles.1 }}, the object does not have any value. {{ Constants.roles.1 }}'s earnings are only the price paid by {{ Constants.roles.0 }} for the object.

Price of the object:

{% if participant.vars.treatment == 'manualrand' %}

The price is randomly drawn from all prices that {{ Constants.roles.1 }} players set in a previous experiment where the results of the die roll was automatically reported.

{% else %}

The price it set by {{ Constants.roles.1 }}. /

{% endif %}

{{ Constants.roles.0 }}'s earnings:

If trade takes place: the balance from the die roll phase minus the price for the object, plus 12 points for the object.

If trade does not take place: only the balance from the die roll phase.

{{ Constants.roles.1 }}'s earnings:

If trade takes place: The price that {{ Constants.roles.0 }} pays.

If trade does not take place: Zero

The trade takes place if the price is lower or equal to {{ Constants.roles.0 }}'s balance. Is the price higher than the balance that {{ Constants.roles.0 }} earned in the die roll phase, the trade does not take place.

{{ Constants.roles.0 }} and {{ Constants.roles.1 }} are told before the interaction how the value in the die roll phase is reported: by {{ Constants.roles.0 }} or automatically.

Time limit:

{{ Constants.roles.0 }} and {{ Constants.roles.1 }} have {{ Constants.max_seconds_on_page.price_page }} seconds time to report the balance or to set the price. {% if participant.vars.treatment == 'manualrand' %} The randomly selected price will be automatically saved after {{ Constants.max_seconds_on_page.price_page }} seconds. {% else %} If {{ Constants.roles.1 }} does not make an input within those {{ Constants.max_seconds_on_page.price_page }} seconds, a random value from {{ Constants.dice.0 }} to {{ Constants.dice.1 }} will be saved. {% endif %} If the balance is automatically reported then it is saved after {{ Constants.max_seconds_on_page.price_page }} seconds. If the balance is reported by {{ Constants.roles.0 }}, then a random value from {{ Constants.dice.0 }} to {{ Constants.dice.1 }} will be saved instead.
