"Small and medium enterprises (SMEs) are thought to be important drivers of growth in developing economies, but entrepreneurs in these countries face many barriers, including poor access to training, finance, and business networks. In Colombia, Fundación Bavaria's "Destapa Futuro" (Open the Future) program identifies promising enterprises and provides them with a suite of financial, technical, business, and training resources. Researchers found that the trainings did not affect key business outcomes, such as sales and profits, but helped entrepreneurs to expand their business networks."

"Large amounts of funding are going towards programmes to support small and medium enterprises (SMEs) in low- and middle-income countries in order to increase revenue and profits, generate employment, and, so, create economic growth and reduce poverty. The Campbell review summarizes evidence of the impact of these programmes on measures of SME performance including revenues, profits, and productivity, as well as the firms’ ability to generate employment and increase their labour productivity Included studies examine interventions targeted at SMEs (up to 250 employees) involving tax simplification, exports and access to external markets; support for innovation policies; support to local production systems; training and technical assistance, and SME financing and credit guarantee programmes. Findings from 40 studies are summarised in the review. These studies present evidence from 18 low- and middle-income countries, with 26 studies analysing programmes in Latin America, six from Asia and five from Africa."

"We document the presence of multiple and varied constraints to small and medium firm growth. This presents both a practical problem for business training programs and a challenge to academic economists trying to identify mechanisms through which these programs may affect outcomes. External validity needs theory. This pushes researchers to narrowly defined and highly selected sample frames, which limits the potential for clear, generalizable policy prescriptions. Ultimately, larger samples, multi-arm evaluations, process documentation, and narrowly-focused, theory-supported empirical work are all needed, but the complexity of the problem limits what we learn from any single study."

"This paper explores the effectiveness of goal setting and accountability within group-based entrepreneurship initiatives in creating human capital. The study uses a randomized cluster trial to compare the experimental and control groups of entrepreneurs. The results suggest that frequent goal setting and accountability in group settings provides a greater number of learning experiences and human capital development opportunities available to entrepreneurs than those that did not engage in the same level of goal setting."

"This paper attempts to assess the impacts of a management training program on the business performance of small enterprises in a metalworking cluster in Nairobi, Kenya. Based on the observed differences in management between successful and less successful enterprises, we designed a management training program featuring the basics of KAIZEN, an inexpensive, commonsense approach to management emphasizing the reduction of wasted work and materials, for the less successful enterprises.

This paper finds that business owners operating smaller enterprises tended to be self-selected into training participation. The training effects combined with the self-selection effect, which we estimate with panel data, were statistically significant and particularly stronger on profits than on sales revenues, while other training programs that did not teach KAIZEN had positive effects on sales revenues, not profits. As a result, the participants caught up with and overtook the non-participants in terms of average sales revenues and average profits, respectively."

"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."

"As part of its Agribusiness Innovation Program (AIP), infoDev designed an agribusiness incubation training program. To-date, the Agribusiness Incubation Training has been provided to a total of 149 people from 25 countries, including countries from Africa, Asia, Eastern Europe and Latin America. This report analyzes the effects of the delivery of this training. The agribusiness incubation training sessions took place as a one-day-training1 in the context of seven different events."

"Recent field experiments demonstrate that advice, mentorship, and feedback from randomly assigned peers improve entrepreneurial performance. These results raise a natural question: what is preventing entrepreneurs and managers from forming these peer connections themselves? We argue that entrepreneurs may be under-networked because they lack the necessary social skills- the ability to communicate effectively and interact collaboratively with new acquaintances-that allow them to match efficiently with knowledgeable peers. We use a field experiment in the context of a business training program to test if a short social skills training module improves who the participants choose to learn from within the program. We find that entrepreneurs who were exposed to the social skills training formed 50% more relationships with peers. These relationships exhibited more matching based on managerial skill and were more ethnically diverse. Finally, the training also substantially increased entrepreneurs' business performance. Our findings suggest that social skills help entrepreneurs build relationships that create value for both themselves and their peers."

"Identifying the determinants of entrepreneurship is an important research and policy goal, especially in emerging market economies where lack of capital and supporting infrastructure often impose stringent constraints on business growth. This paper studies the impact of a comprehensive business and financial literacy programme on firm outcomes of young entrepreneurs in an emerging post-conflict economy, Bosnia and Herzegovina. The authors conduct a randomised control trial and find that, while the training programme did not influence business survival, it significantly improved business practices, investments and loan terms for surviving businesses. Female-run businesses further exhibited some improvements in business performance and sales."

"Despite the popularity of business training among policy makers, the use of business training has faced increasing skepticism. This is, in part, fueled by the fact that most of the first wave of randomized experiments in developing countries could not detect statistically significant impacts of training on firms' profits or sales. This paper revisits and reassesses the evidence for whether small business training works, incorporating the results of more recent studies. A meta-analysis of these estimates suggests that training increases profits and sales on average by 5 to 10 percent. The author argues that this is in line with what is optimistic to expect given the relatively short length of most training programs, and the expected return on investment from the cost of such training. However, impacts of this magnitude are too small for most experiments to detect statistically. Emerging evidence is provided on five approaches for improving the effectiveness of traditional training by incorporating gender, kaizen methods, localization and mentoring, heuristics, and psychology. Training programs that incorporate these elements appear to deliver improvements over traditional training programs on average, although with considerable variation. Given that training delivers some benefits for firms, the challenge is then how to deliver a quality program on a cost-effective basis at a much larger scale. Three possible approaches to scaling up training are discussed: using the market, using technology, or targeting and funneling firms."
