Before
Randomization will take place via computer. There are two levels of randomization:
- Randomization of sessions to treatment or control and
- Randomization of groups.
We explain each in turn.
Randomization of Role Assignment Mechanism
We randomly allocate each session to either be a ‘self selection’ or ‘no choice’ treatment. Sessions will be equally split across these conditions, as we will use pair randomization. Pairs will be sessions that are closest together in time.
Randomization of Groups
To run a study ‘session’ there must be at least n=12 participants. Ideally, there will be n=15 participants at a time. Workers are randomly assigned to managers, with two constraints: if possible, we do not consider groupings in which workers are allocated to a manager they have worked with before. Second, workers are allocated to a manager at least once (e.g., when n=15, they are allocated to each manager once). See detailed analysis plan for further details. The ordering in which groups are matched to managers are randomized.
When the number of participants who show up to a session is not divisible by 3, we randomly select participants to withdraw until we have the correct number. Participants who are withdrawn are paid an appearance fee for their time.
