Prior work
This trial is based on or builds upon one or more prior RCTs.
In a world of incomplete information, individuals make decisions based on more or less precise beliefs about their own ability. One important determinant in the formation of beliefs about one’s ability are comparisons to others. This study’s aims are twofold: i) understanding the individual determinants of the demand for relative feedback as well as ii) understanding the effects of receiving individual feedback about one’s own performance on job search.

Experimental Design

Experimental Design
We invite job seekers to a survey-based assessment of their skills, among them a test of general intelligence (Raven's Progressive Matrices or RPM). Approximately one week after the assessment of skills, individuals receive feedback about their performance in the test relative to other job seekers. We implement two different interventions: a control condition in which subjects do not receive any feedback about their ability and a treatment group directly receiving unsolicited feedback.
Experimental Design Details
The research design is implemented as a field experiment in Addis Ababa, Ethiopia. We invite job seekers to participate in a baseline survey and an assessment center. Within the baseline survey, subjects participate in a battery of tests for cognitive and non-cognitive skills, including an extensive test of general intelligence (Raven test). During the baseline survey, we also elicit every respondent’s willingness to pay for relative feedback based on incentivized survey questions. We further elicit prior beliefs about relative ability compared to other job seekers.

Approximately one week after participation in the baseline survey, participants are contacted again via phone. In the control condition, participants are reminded about the assessment center and then participate in a short survey. In the feedback condition, participants are additionally provided with feedback about their relative performance in the RPM test in comparison with other job seekers in a previous sample from 2019.

Three to five weeks after the initial baseline survey, we conduct a follow-up survey with all individuals.
Randomization Method
Stratified randomization after baseline data collection in batches using Stata.
Randomization Unit
All individuals which participated in a baseline survey each week.
Was the treatment clustered?

Experiment Characteristics

Sample size: planned number of clusters
Number of clusters is equal to number of observations.
Sample size: planned number of observations
We expect the experiment to run for about five months. All individuals that participate in the baseline survey will participate in the experiment and will be randomized into treatments.
Sample size (or number of clusters) by treatment arms
All treatments will be sampled with an equal weight of 1/2.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
