In Simple Words
Think of giving a gardener extra money to buy a massive industrial lawnmower for a small backyard plot. The gardener spends the cash immediately on the mower and extra gas, but the yard is not big enough to bring in extra income to cover maintenance costs. After realized earnings drop from operating the oversized setup, the gardener stops buying extra gas and lets the lawnmower sit idle, returning to their original small push-mower routine. Direct capital grants allow micro-entrepreneurs to purchase equipment, but without higher underlying customer demand or managerial capacity, the additional capital produces negative average returns.

Development interventions frequently assume that microentrepreneurs are severely credit constrained and that direct cash injections will yield high returns on investment and sustained firm expansion. However, evaluating whether cash grants generate positive profits or merely temporary capital reallocation remains a critical empirical question.
Participants
160 urban microenterprise tailors in Accra, Ghana, where 82.5% had never accessed formal credit markets.
Study Design
Randomized controlled trial providing an unconditional cash grant of 200 cedis (~US $133, doubling average baseline working capital) to 75 tailors (36 capital-only, 39 consulting-plus-capital), measuring investment flows, savings, and profits across eight rounds over two years.
Results
Grant recipients invested an average of 179 cedis more than control firms in baseline-targeted categories within two months (p < 0.10). However, capital grants caused a statistically significant post-treatment drop in monthly business income of 45 cedis (p < 0.05) against a control mean of 146 cedis, with 95% confidence intervals ranging from -66% to -1%.
Takeaway
Evaluate firm-level baseline demand and operational capacity prior to awarding unconditional capital grants to avoid induced negative profit 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.
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.
GET-IT glossary · Randomized study ↗Read more about randomized controlled trial →- Statistically significant
A label used when a result passes a chosen statistical threshold, often p < 0.05. It does not show how large or useful an effect is. A result that is not statistically significant does not prove there is no effect.
ExampleA study reports p = 0.03 against a 0.05 threshold. It passes that test, but the effect could still be too small to matter.
