Observability Gradient in Labor Market Beliefs

In Simple Words

Imagine going to a grocery store where every box has a clear, accurate price tag printed on the outside, but the ingredient quality inside the sealed boxes is unknown. Shoppers can accurately recite what items cost across every aisle, but hold wildly incorrect beliefs about how nutritious the packaged food actually is until they open the boxes and test the contents.

Research question

Economic agents do not suffer from uniform information deficits across all market dimensions. Market participants acquire accurate information about publicly visible aggregate parameters (such as prevailing wage rates), but maintain severe structural misperceptions about private, unobservable traits (such as candidate cognitive ability or true hiring standards).

Participants

N = 779 jobseekers and N = 395 firm managers in Addis Ababa, Ethiopia.

Study Design

Elicitation of jobseeker beliefs regarding occupational wage distributions versus beliefs regarding employment probabilities and candidate Raven's test scores, benchmarked against true sample distributions.

Results

Jobseekers' stated wage distributions closely matched prevailing firm salary data across occupational tiers, whereas jobseeker expectations of permanent employment (55% expected permanent job within 1 year vs 5.8% actual) and firm estimates of tertiary applicant cognitive test scores (overestimating tertiary ability premium by more than 4 times) exhibited massive structural biases.

Takeaway

Focus labor market information policies on revealing unobservable quality attributes (such as standardized skill certifications and employer selection thresholds) rather than broadcasting public wage data.

  Think of a two-sided market as a high school dance where boys expect all girls to be professional dancers, while girls expect all boys to give out tickets to a VIP lounge. Because neither side has seen the actual crowd before, both set unrealistic entry standards; when the dance starts, boys refuse to dance with regular dancers and girls reject normal invitations, leaving most people standing on the sidelines until they observe the actual room.
