Match Quality Optimization via Noise Reduction
Employers face high uncertainty when evaluating job applicants with unobservable abilities, leading to misallocated labor, high job turnover, and poor skill utilization.
Picture this
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.
What the evidence says
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).
- Who
- N = 1,739 job-seekers for job tenure evaluation and N = 1,383 for current employment analysis in Addis Ababa, Ethiopia.
- How
- Randomized Controlled Trial (RCT) evaluating longest work spell duration, skill utilization, and conditional earnings four years post-treatment.
What to do
Provide standardized multi-dimensional competence testing to job candidates to lower evaluation noise for prospective employers during hiring decisions.
From the source
"First, treated young people stay in the same job for a longer period of time. Employment duration is often considered a key indicator of match quality as it is evidence that both the firm and the employee value the match."
