Abstract
We run a online experiment to understand what is the effect of learning other players' payment in a hierarchical group. The participants will complete two games: a costly punishment game and a sorting task. In the punishment game the players can reduce the payment of the other group members at a cost, while in the sorting task they will choose which group would they want to join. We randomly vary the information participants see about their peers' payment.

Primary Outcomes
Primary Outcomes (end points)
Punishment behavior, choice in sorting task.
Primary Outcomes (explanation)
We specify the outcomes in the pre-analysis plan.
Secondary Outcomes
Secondary Outcomes (end points)
Beliefs about self, beliefs about other's payments, estimated social preferences.
Secondary Outcomes (explanation)
We specify the outcomes in the pre-analysis plan.
Experimental Design
Experimental Design
Our main experimental variation changes the information that a participant has about other players' payment. We will test how information changes the agents behavior in two games: in a costly punishment game and in a sorting game.

The detailed experimental design is in the pre-analysis plan.

Experiment Characteristics
Sample size: planned number of clusters
350 people
Sample size: planned number of observations
350 people
Sample size (or number of clusters) by treatment arms
In the punishment game: 150 individuals in the hidden information, 150 individuals in the full information.
The sorting game is a within subject variation.
