Abstract
We study whether the gender of co-workers matters for information exchange and performance in teams. We carried out a lab-in-the-field experiment where `test-takers’ were randomly assigned `helpers’. Helper allocation was randomized on two dimensions: (1) gender and (2) test-taker preference for that helper at baseline. To directly investigate frictions in information exchange, we cross-randomized the availability of hints to help with the task.

Secondary Outcomes (explanation)

Experimental Design

Experimental Design
We conduct a lab-in-the-field experiment with university students studying Economics in Pakistan. We split participants into ‘test-takers’ whose outcomes we study, and ‘helpers’, who help test-takers perform. The treatment uses a within-person rotation design. The same test-taker randomly matched with different helper across rounds and in each test given hints in some questions and not in others.
Experimental Design Details
T1: Randomly chosen helpers (of either gender)
T2: Preferred helper (of either gender)
T3: Hint available vs no hint in questions (cross-randomized over helper allocation)
Control: Without helper, with and without hints
Randomization Method
Public lottery through picking pieces of paper from a bowl. For the preferred helper treatment, we used a random serial dictatorship starting from the right hand corner of the aisle where test-takers sat.
Randomization Unit
Individual
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
85 male and 85 female students (as test-takers)
Sample size: planned number of observations
6 tests per test-takers with 30 questions per test. 6x30x85=15300 male and15300 female test-takers
Sample size (or number of clusters) by treatment arms
Rotation design so 85 per treatment arm. They are their own controls.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
The study sample was limited by the number of women, we invited ALL women that were studying in the university.
