In Simple Words
Imagine a restaurant facing two different bottlenecks: in a busy town, management struggles because few people apply for jobs, whereas in a quiet town, management struggles because hundreds apply and reviewing every resume takes too long. Screening assistance helps management in both situations by solving opposite sides of the same operational delay.
Estimated outreach gains by local labour market
- Below-median market tightness
- More vacancies with screening estimated
- Above-median market tightness
- More vacancies with screening estimated
Trial subgroup analysis across market conditions. No clear difference detected; this does not prove equal effects. Market tightness was not randomized.

Traditional economic policy assumes firm-directed recruitment assistance is ineffective during economic downturns when candidate supply is abundant and firms face minimal candidate-generating frictions.
Participants
N = 7,438 firms across French commute-zone micro-markets categorized by baseline labor market tightness (median tightness = 0.35).
Study Design
Stratified Randomized Controlled Trial evaluating treatment effect heterogeneity across low (below-median) and high (above-median) labor market tightness sub-samples.
Results
The treatment impact on permanent vacancy creation with pre-screening services was statistically equivalent between low-tightness markets (+0.033) and high-tightness markets (+0.061) with a p-value for equal treatment effect of 0.386.
Takeaway
Deploy firm recruitment assistance programs continuously across both recessionary and expansionary macroeconomic cycles, switching service focus from candidate generation to applicant filtering.

Original explanations, informed by the references below. Examples are illustrations, not data from the studies above. The research text stays unchanged.
- Median
The middle number after arranging the values from smallest to largest. If there are two middle numbers, use their average.
ExampleFor the values 2, 4 and 12, the middle value is 4. The median is 4.

The starting measurements in a study. Researchers use these to compare what participants were like at the start with what happens later.
ExampleBefore a training programme starts, researchers measure workers’ earnings. That first measurement is the baseline.
GET-IT glossary · Baseline characteristics ↗Read more about baseline →- Randomized controlled trial
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.
