In Simple Words
Imagine a high wall separating two towns. The obvious problem is that people cannot travel across to trade easily. But the hidden, secondary problem is that because nobody crosses the wall, people in both towns invent wildly inaccurate stories about what the other town is like, leading them to make foolish preparation choices whenever they finally try to trade.
Young job seekers in the companion trial
- Study comparison group
- Comparison visit probability
- Job-fair intervention
- 26% more likely to visit job boards
Six weeks after the first fair. Invitation raised the probability of visiting job boards; the two fair variants are pooled. Belief correction remains a proposed explanation.

Traditional search models focus on the direct operational costs of search frictions, such as reduced hiring rates and prolonged unemployment spells. However, search frictions also limit mutual exposure between market participants, creating an indirect second-order cost by entrenching inaccurate beliefs about overall labor market fundamentals.
Participants
N = 4,059 young jobseekers (aged 18–29) and N = 498 formal employers in Addis Ababa, Ethiopia.
Study Design
Field experiment assessing direct match placements versus post-fair adjustments in search strategies and expectations across a 12-month panel.
Results
The job fair produced minimal direct hiring (1 hire per 12 attending firms), but the temporary reduction in meeting costs corrected underlying misperceptions, driving a 26% increase in job board visits among jobseekers within 6 weeks and a 12 percentage point increase in professional vacancy advertising by firms (p < 0.01).
Takeaway
Evaluate active labor market programs by measuring long-term behavioral changes in search strategy and belief calibration rather than evaluating interventions solely on immediate direct match placements.
