In Simple Words
Think of building a tower with prefabricated structural blocks. Instead of needing a massive concrete foundation already in place to add more height, structured adult soft skills training acts as a custom support harness, yielding the largest height gain for the towers that were previously the shortest and least supported.
Bengaluru workers grouped by initial leadership
- Lower leadership rating
- Larger productivity gain from training
- Higher leadership rating
- Gain was 4.3 percentage points smaller
Post-program efficiency gains compared within each subgroup. Leadership was rated before training, not randomly assigned; differential significant.

Economic models of dynamic human capital formation suggest that early non-cognitive skill deficits are difficult to remediate in adulthood due to dynamic complementarities requiring high baseline stocks.
Participants
N = 2,703 female garment workers (258,285 daily worker observations for heterogeneity estimations) in Bengaluru, India.
Study Design
Two-stage randomized controlled trial (RCT) with interaction terms for HR-rated baseline leadership tiers (top 2 vs bottom 2 of 4 levels), educational attainment, and technical machine operator status.
Results
Productivity gains were significantly higher for workers with low baseline leadership skills (-4.3 percentage point differential for high baseline leaders, p < 0.05) and those without education above primary school (-7.59 percentage point differential for higher education, p < 0.10), proving adult soft skills training acts as a substitute for baseline skill stocks.
Takeaway
Target enterprise soft skills training programs preferentially to frontline employees identified as lacking baseline leadership or formal education to maximize marginal productivity returns.

- 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.
