"A randomized control trial with 945 entrepreneurs in Jamaica shows positive short-term impacts of soft-skills training on business outcomes. The effects are
concentrated among men, and disappear twelve months after the training. We argue that the main channel is increased adoption of recommended business practices, exclusively observed in the short run. We see persistent effects on an incentivized behavioral measure of perseverance after setbacks, a focus of this training. We compare a course focused only on soft-skills to one that combines soft-skills training with traditional business training. The effects of the combined training are never statistically significant."

"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 tested whether a psychology-based personal initiative training approach, which teaches a proactive mindset and focuses on entrepreneurial behaviors, could 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 a personal initiative training program (n = 500). Four follow-up surveys tracked outcomes for firms over 2 years and showed that personal initiative training increased firm profits by 30%, compared with a statistically insignificant 11% for traditional training. The training is cost-effective, paying for itself within 1 year."

"We seek to show how evidence-based teaching for management affects the success of firms by way of changing managers’ actions. We conducted a randomized controlled field intervention with a sample of 100 small business owners in Kampala, Uganda. The intervention increased personal initiative behavior and entrepreneurial success over a 12-month period after the intervention. An increase in personal initiative behavior was responsible for the increase of entrepreneurial success (full mediation). Thus, the training led to an entrepreneurial mind-set and to an active approach toward entrepreneurial tasks. This particular management training was successful at improving knowledge and intangible skills that translated into successful organisational medium- to long-run outcomes for small businesses."
