Belief Entrenchment Cost of Search Frictions
RCTReview
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.
Picture this
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.
What the evidence says
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).
- Who was studied
- N = 4,059 young jobseekers (aged 18–29) and N = 498 formal employers in Addis Ababa, Ethiopia.
- How
- Field experiment assessing direct match placements versus post-fair adjustments in search strategies and expectations across a 12-month panel.
What to do
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.
From the source
"This suggests that, beyond slowing down matching, search frictions have a second understudied cost: they entrench inaccurate beliefs, further distorting search strategies and labour-market outcomes."
