In Simple Words
Think of a home cook given a free set of fancy commercial kitchen tools and a high-end chef's recipe book. The cook tries the new tools and complex recipes to see if they can run a catering business. When the meals take too long, cost too much, and fail to generate income, the cook realizes the expanded setup is unprofitable and goes back to basic home cooking.
Tailors with small businesses
- No consulting before grants
- Group used for comparison
- Consulting before grants
- 5.65 percentage points more practices adopted
Six months after consulting began, before grants. Consulting groups pooled; learning was not separately tested. No clear final practice advantage.

Microentrepreneurs often operate with imperfect information regarding their own managerial ability and the optimal scale for their enterprise. When financial or managerial capital constraints are relaxed, business owners experiment with higher-scale operations or complex practices, but these exploratory changes frequently fail to increase long-term profitability.
Participants
N = 160 urban microenterprise tailors and seamstresses (human subjects with five or fewer employees) in Accra, Ghana.
Study Design
Randomized Controlled Trial (RCT) featuring four experimental arms (Control N=45, Consulting N=41, Capital Grant N=36, Both N=36) evaluated across 8 survey rounds over two years (2008–2011).
Results
Initial adoption of business practices increased management scores by 5.65 percentage points at 6 months (p < 0.01) and capital grants increased short-run investments by 179 cedis (p < 0.10). However, treatments led to non-positive or negative income shifts (capital treatment reduced stated income by 45.43 cedis, p < 0.05), causing microentrepreneurs to abandon new business practices and revert back to baseline scale within 1 to 2 years.
Takeaway
Evaluate microenterprise intervention outcomes over a multi-year post-treatment horizon rather than relying on short-term adoption metrics.

- 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.
