Experimental Design (Public)
|
Before
In this randomized control trial, we have two main stages of randomization through a factorial design: half of workers are assigned a female manager, half a male manager. We then provide 60% of each group with performance feedback. The other 40% does not receive any feedback and will thus serve as the control group for the feedback treatment.
In addition, we randomly assign the difficulty of the task (more details in pre-analysis plan).

Planned Number of Observations
|
Before
1,100 workers
|
After
2,600 workers. This sample is pooled with the sample of a companion project that explores the effect of manager race (see AEARCTR-0004225)

Sample size (or number of clusters) by treatment arms
|
Before
550 are assigned to each female and male manager.
For each female and male managers, 60% receive feedback on performance.
|
After
1300 are assigned to each female and male manager.
For each female and male managers, 60% receive feedback on performance.
