Primary Outcomes (Explanation)
|
Before
The outcome is participants' choice on how to split the bonus between two workers. They are asked this in terms of percentages. This means that our outcome is the percentage of the bonus awarded to the participant who chose their own share of the bonus and their counterpart in the control group. We round percentages to the next 5 percent mark.

After
The outcome is participants' choice on how to split the bonus between two workers. They are asked this in terms of percentages. This means that our outcome is the percentage of the bonus awarded to the participant who chose their own share of the bonus and their counterpart in the control group.
Change and explanation. Change decided on 19/10/21 before launching data collection for spectators but after collecting worker data that the spectators will decide on. We had pre-registered rounding to the next 5% in order to be able to create treatment and control group worker pairs that are perfectly matched on performance. After we collected worker data, we found that this a) is not necessary to obtain perfect matches on performance and b) will give an overhang of worker pairs with 50/50 performances, meaning that spectators loose information.
Therefore, we will only round performances to the next 1%, rather than the next 5% before matching.
