High turnover rates are a major issue in industrialization of developing countries. In one of the major industrial parks in Ethiopia, we identify a key determinant of turnover from our pilot study – career incentives. Despite the importance of career incentives during job search, workers have substantial misperceptions of career incentives within the industrial park, and it is difficult for workers to learn the true career incentives from on-the-job experience. We propose an intervention that provides accurate information of promotion likelihood and salary after promotion to understand how the intervention might help workers learn about the career incentives, and to causally estimate the effect of misperceptions of career incentives on workers’ turnover. We plan to sample 1,200 new female young workers, randomly provide the information of the career path on 400 workers, and follow up workers after 45 days and 6 months to understand how misperceptions prevent workers from optimal job search, and the causal effect on long-run employment and welfare outcomes.

Primary Outcomes

Primary Outcomes (end points)
Updated perceptions of job characteristics of the industrial park, whether workers stay in the firm in the follow-up surveys
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
Worker's effort (absent days, overtime, performance pay collected from firms' records), welfare outcomes (income, consumption, health), plans in the future (education, marriage, migration), skills (cognitive and dexterity)
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
We will implement a clustered randomized experiment on 1,200 female young workers. Workers will be sampled over the course of 50 days. We will randomly select 25 days, randomly select 2/3 of the workers on those days, and provide them with true promotion likelihood ("Out of 100 entry-level workers, how many of them will be promoted to upper level?") and salary after promotion ("What's the average salary of upper-level positions?").
Experimental Design Details
Randomization Method
We will generate a randomization file before the intervention that pre-determines workers with certain IDs on certain days will be treated.
Randomization Unit
The randomization is clustered by days of hires. Within the treated clusters, individuals will be randomly treated.
Was the treatment clustered?

Experiment Characteristics

Sample size: planned number of clusters
50 days of hiring
Sample size: planned number of observations
Sample size (or number of clusters) by treatment arms
25 treated clusters (600 workers), 25 control clusters (600 workers). Within treated clusters, 400 out of 600 workers are treated.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
