Abstract
Many occupations are highly segregated with respect to gender. In predominantly male or female professions, there is often discrimination against the underrepresented gender. This perpetuates gender imbalances. The discrimination could be due to perceived job-specific
productivity differences between men and women. Alternatively, it could result from the belief that teams whose members have the same gender perform better. We investigate the two possible explanations in a novel experiment that varies the initial gender
composition of the teams. We employ three tasks that differ with respect to gender stereotypes.

Experimental Details

Interventions

Intervention(s)
- We vary the initial gender composition of the four-person group (all female or all male) and whether a woman or man is added to the group
- We also vary the task the groups perform (building shelves, memory, network).
Intervention Start Date
2021-05-31
Intervention End Date
2021-08-31

Primary Outcomes

Primary Outcomes (end points)
- Choices (binary productivity estimates) between a gender-homogeneous team that remains homogenous and a team that becomes heterogeneous (six choices, one for each combination of task (building shelves, memory, or network) and initial gender composition (all-female or all-male)).
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
- Beliefs about the choices of (eleven) other participants between a gender-homogeneous team that remains homogenous and a team that becomes heterogeneous (six choices, one for each combination of task and initial gender composition).
- Binarized version of this belief measure (six choices, one for each combination of task and initial gender composition).
- Choices (binary productivity beliefs) between an all-female team and an all-male team (three choices, one for each task).
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
Gender-homogeneous groups consisting of four women or four men perform one of three different tasks. We then replace one worker with a new subject (either female or male), and study how this affects performance expectations and beliefs about the performance expectations of others.
