Opportunity Cost of Vocational Training

In Simple Words

Think of a worker taking unpaid leave from a part-time job to attend a full-time certification program. Without a stipend to replace their lost daily wages, the worker cannot afford food and rent during the program, forcing them to drop out regardless of future pay raises.

Research question

Enrolling in full-time dual apprenticeship forces low-skilled youth to forgo immediate income from casual wage work and self-employment. Understanding youth participation constraints requires evaluating whether subsidies compensate for these short-term earnings losses.

Participants

N = 1,661 youth tracked at midline (20 months post-baseline) across 7 urban localities in Côte d'Ivoire.

Study Design

Inversely propensity weighted RCT analysis comparing treatment and control group earnings across occupations.

Results

Short-term labor earnings in the treatment group fell by 10,494 FCFA/month (-25%, p < 0.001) due to reductions in wage work (-6,414 FCFA) and self-employment (-6,381 FCFA). The monthly program stipend of 10,213 FCFA fully offset these forgone earnings, resulting in zero net change in total short-term income.

Takeaway

Structure participant stipends to match or exceed lost casual labor earnings to eliminate short-term financial barriers during intensive training programs.

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.

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.

Related findings

• Employed vs. Unemployed MVT Divergence →Labour & employment

  Think of offering overtime hours to two people: one who is currently jobless and sitting at home, and one who already works a second side-hustle paying $15/hour during those same hours; the employed person demands a higher wage because taking the new hours means giving up real earnings from their second job, not just giving up TV time.

• Private Sector Wage Subsidies →Labour & employment

  Instead of paying a job seeker to perform community service tasks, the government pays a private business owner half of the job seeker's wage for six months. This acts like a temporary half-off coupon for employers, giving them a low-risk way to test and hire new staff in real commercial settings.

• Subsidized Employment Pathway Acceleration →Labour & employment

  Think of learning to swim using temporary floatation armbands. While confident swimmers do not need auxiliary support, struggling beginners benefit from temporary support that gets them moving in the water until they can swim unassisted.

• Total Opportunity Cost Parameter (z) →Labour & employment

  Think of accepting a job like purchasing a ticket where the cost is not just the sticker price of lost free time, but also includes mandatory convenience fees like commuting fuel, lost government assistance, and paying for childcare.
