In Simple Words
Imagine tuning a static-filled radio station to a crystal-clear frequency—when the music is crisp, listeners can easily decide if they like the song and stay tuned longer. Lowering the noise in job applicant skill signals allows employers to accurately evaluate worker-job fit, leading to longer employment tenure and higher wages for properly matched roles.

- Job application workshop
- About 10% longer longest work spell
Four-year follow-up. Longest completed spell; estimate significant at 10%. This is the whole workshop, not certification alone. Transport arm omitted.
See source →Research question
Employers face high uncertainty when evaluating job applicants with unobservable abilities, leading to misallocated labor, high job turnover, and poor skill utilization.
Participants
N = 1,739 job-seekers for job tenure evaluation and N = 1,383 for current employment analysis in Addis Ababa, Ethiopia.
Study Design
Randomized Controlled Trial (RCT) evaluating longest work spell duration, skill utilization, and conditional earnings four years post-treatment.
Results
Workshop skill certification increased the longest completed employment tenure by 1.2 months (a 10% increase over the 11.85-month control mean, p < 0.10), increased skill utilization in current jobs by 8.2 percentage points (p < 0.05), and raised earnings conditional on employment by 370.4 ETB (a 15% increase, p < 0.05).
Takeaway
Provide standardized multi-dimensional competence testing to job candidates to lower evaluation noise for prospective employers during hiring decisions.

A study that uses chance, like drawing lots, to decide who receives each option being compared. Researchers compare the groups’ outcomes to estimate the effect of those options.
ExampleA lottery assigns volunteers to a training programme or a comparison group. Researchers then compare their outcomes.
