Education-Driven Apprentice Self-Selection

In Simple Words

Adding a monthly living stipend and a recognized classroom diploma to hands-on vocational training is like adding a full scholarship and college credit to a trade apprenticeship. This combination convinces high school graduates—who would normally hold out for office jobs—to apply for manual trade training alongside less-educated applicants.

Research question

Traditional informal apprenticeships in developing economies primarily absorb youth with little or no education. Introducing formal subsidies and structured dual training alters applicant self-selection, attracting older and more educated youth with better outside labor market options.

Participants

N = 1,842 eligible youth applicants and 948 surveyed apprentices across 7 urban localities in Côte d'Ivoire.

Study Design

Instrumental variable and OLS regression comparing baseline characteristics and follow-up profiles of formal apprentices against traditional apprentices in control firms.

Results

Formal apprentices were 47.5 percentage points less likely to have no education (p < 0.0001), 34.8 percentage points more likely to have completed primary education (p < 0.0001), 2.10 years older on average (p < 0.0001), and 23.0 percentage points more likely to aspire to formal wage employment (p < 0.0001) compared to traditional apprentices in control firms.

Takeaway

Account for self-selection shifts toward higher-educated participants when evaluating subsidized dual training programs to isolate human capital gains from baseline worker quality.

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.

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.

Percentage points

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.
