In Simple Words
Imagine a fisher who believes a lake is teeming with giant prize fish and casts a line casually once a day. After spending an entire weekend at a crowded fishing tournament catching only small fish, the fisher realizes prize fish are much rarer than expected. Instead of quitting, the fisher realizes they must wake up earlier, buy better bait, and cast ten times a day to catch enough food.
Young job seekers in the companion trial
- Study comparison group
- Comparison visit count
- Job-fair intervention
- About 3 more job-board visits
Six-month endline after the last fair. Invitation increased reported job-board visits by about three, p below 0.05; the two fair variants are pooled. Belief changes are a proposed pathway.
See source →Research question
Jobseekers and formal employers frequently hold inaccurate, overly optimistic baseline expectations regarding market wages and candidate abilities. When economic agents engage in low-yield market interactions, the resulting reality check forces a downward recalibration of expectations that prompts increased search effort.
Participants
N = 1,007 invited young jobseekers (aged 18–29; 606 attending) and N = 248 formal firms (170 attending) in Addis Ababa, Ethiopia.
Study Design
Individual and cluster-randomized controlled trial with 6-month endline follow-up and high-frequency biweekly phone panel surveys.
Results
Market exposure reduced worker reservation wages by 6.6% (p < 0.10) and wage mismatch by 4.2% (p < 0.10), while increasing job board visits by 3.01 visits (p < 0.05); treated firms increased professional vacancy advertising by 12 percentage points (p < 0.01) and job board recruitment by 9.6 percentage points (p < 0.05).
Takeaway
Deploy structured multi-counterparty exposure events to induce empirical recalibration of expectations among over-optimistic market participants rather than relying solely on passive advice.

- Follow-up
Collecting more information about participants later in a study to see what has happened to them. The term can also mean the length of time researchers keep track of them.
ExampleResearchers interview the same workers three months after a programme ends. That later interview is a follow-up.
GET-IT glossary · Follow-up ↗Read more about follow-up →- Baseline
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.

The difference between two percentages.
ExampleA rise from 40% to 50% is 10 percentage points. Relative to the starting value, that is a 25% increase.
Office for National Statistics · Percentages ↗Read more about percentage points →- 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.
