In Simple Words
Imagine trying to operate a smartphone when the battery drops below 5%. The operating system automatically throttles performance and slows down applications to save power. Giving a low-asset worker an interim cash infusion acts like plugging in a charger, immediately restoring maximum processing speed and task accuracy.
Odisha workers with below-median wealth
- Pay at contract end
- Comparison group
- Part of pay arrives early
- Hourly output rose by 13%
Below-median wealth subgroup. After interim pay through contract end; effect significant. Wealth index combines assets and access to cash.

Low-asset workers face a severe cognitive tax from poverty, as unresolved financial strain consumes mental focus and suppresses earning capacity precisely when income is most needed.
Participants
N = 408 male manufacturing workers, Odisha, India (N = 407 with complete baseline wealth index data).
Study Design
Heterogeneity analysis within an RCT comparing below-median versus above-median baseline wealth workers using a composite index of housing quality, land ownership, grocer credit usage, and emergency cash availability.
Results
Below-median wealth workers experienced a 0.204 SDs (13.0%) output increase (p=0.003) and a 0.133 SD decrease in attentional lapses (p=0.037) following cash receipt, whereas above-median wealth workers showed virtually zero productivity response (+0.014 SDs, p=0.819).
Takeaway
Target interim liquidity distributions specifically toward low-asset workers to achieve maximum workplace productivity gains and error reduction.

Original explanations, informed by the references below. Examples are illustrations, not data from the studies above. The research text stays unchanged.
- Median
The middle number after arranging the values from smallest to largest. If there are two middle numbers, use their average.
ExampleFor the values 2, 4 and 12, the middle value is 4. The median is 4.

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.
GET-IT glossary · Baseline characteristics ↗Read more about 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.
