Abstract
Standard business training programs aim to boost the incomes of the millions of self-employed business owners in developing countries by teaching basic financial and marketing practices, yet the impacts of such programs are mixed. We test whether a psychology-based personal initiative training approach which teaches and promotes a proactive mindset that focuses on entrepreneurial behaviors can have more success. A randomized controlled trial in Togo assigned microenterprise owners to a control group (N=500); a leading business training program (N=500); or to personal initiative training (N=500). Four follow-up surveys track firm outcomes over two years and show personal initiative training increases firm profits by 30 percent, compared to a statistically insignificant 11 percent for traditional training. The training is cost-effective, paying for itself within one year.

Experimental Design

Experimental Design
In this randomly controlled trial, 500 entrepreneurs were selected to participate in a managerial training, and 500 entrepreneurs were selected to participate in a personal initiative training. Entrepreneurs in each training group received 12 half-day sessions of classroom training followed by four months of one-on-one mentoring. The impact of each type of training will be measured in comparison with a control group, and the effects of the two types of trainings will be compared.
Experimental Design Details
Randomization Method
The randomization was done on a computer in front of representatives from the government, the project, the partners of the project, and the beneficiaries.
Randomization Unit
The randomization was done using stratified random sampling at the individual level.
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of observations
1,500 entrepreneurs
Sample size (or number of clusters) by treatment arms
500 entrepreneurs in the managerial training group, 500 entrepreneurs in the personal initiative training group, 500 entrepreneurs in the control group
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)

Final Sample Size: Number of Clusters (Unit of Randomization)
1500 firms
Was attrition correlated with treatment status?
Yes
Final Sample Size: Total Number of Observations
4 Rounds of follow-up surveys were conducted. Attrition rates averaged 9%, and are reported in Table S1 in the Science paper. Attrition rates varied by up to 2-3 percent by treatment status, and results are robust to these concerns. Total number of firm*time observations is 5633 to 5692 for our main outcomes (Table 1 of Science paper)
Final Sample Size (or Number of Clusters) by Treatment Arms
500 control, 500 traditional training, 500 personal initiative, with attrition rates in different samples given in Table S1 of the Science paper.
