Abstract
The goal of the experiment is to examine whether there is a significant difference in effort and performance between genders, depending on the gender of the subject's "main competitors." Previous studies showed that there are significant gender differences in participation and performance due to differences in attitudes toward competition. In this experiment we focus on how subjects' performance is affected by the gender composition of previous high-performing subjects whose performance information is highlighted prior to and during the task. We use a simple online game with randomized treatment to test for gender differences in outcomes.

Experimental Details
Interventions
Intervention(s)
The experiment is based on an online game, where prior to and during the game subjects are shown different set of recent top scores. We are interested in if their effort and performance depending on the treatment they receive: the gender of the subject's "main competitors".

Primary Outcomes
Primary Outcomes (end points)
We plan to measure effort (number of games played, intensity of game playing) and performance (score).

Experimental Design
Experimental Design
The experiment is based an online game, where subjects try to find and click on as many as they can of a target shape within a set of time range. Prior to and during the game they are shown recent top scores from previous games serving as "results of possible reference groups" for them. Depending on which set of results they are shown, subject's effort and performance are compared between these groups.

Randomization Method
Randomization is built in the online game, done by a computer.
Randomization Unit
We use individual level randomization. Everyone who play the game is assigned to one of the treatments.
Was the treatment clustered?
No
Experiment Characteristics
Sample size: planned number of clusters
-
Sample size: planned number of observations
At least 600 subjects for the pilot experiment, followed by 3000 subjects for the final results.
Sample size (or number of clusters) by treatment arms
At least 200 subjects for each treatment groups for the pilot experiment, followed by 1000 subjects/treatment group for the final results.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
