The brief provides an overview of the ongoing impact evaluation on the Impulso Chileno program, which aims to support Chilean entrepreneurs through financial assistance, training, and mentoring. Previous assessments of entrepreneur training interventions have yielded mixed results. The evaluation of Impulso Chileno holds significance as it examines the unique design and components of the program and their potential impact on business success. By evaluating the combined effect of its components, the evaluation of Impulso Chileno aims to uncover the determinants of business success and drive program improvements. The evaluation employs a Randomized Controlled Trial (RCT) design to assess the program's long-term impact on various business growth indicators such as monthly sales, profits, business practices, and employment.

"Aid agencies and governments spend more than a billion US$ on entrepreneurship training annually. What have we learned about the effectiveness of training? We review research on entrepreneurship training. Classroom-based training remains the most popular method of training owners and managers of small firms. A meta-analysis shows that the standard training model has modestly positive effects, on average, though the effects imply reasonably high returns on investments in training, given low costs per participant. Innovation on this basic training model has increased in recent years, particularly with regard to content. Both personal initiative and rule-of-thumb training show promise for subsistencelevel enterprises. Individual consulting has shown significant positive effects for larger enterprises, but the model is expensive and markets for consulting do not appear to work well. Selection is important, particularly in matching the type of training with the type of enterprise. There are several seemingly promising approaches to training where definitive evidence is lacking. For example, Kaizen approaches and Incubators and accelerators both appear to have positive effects, though the evidence is limited and, in the case of accelerators, it is unclear as yet whether the effects come primarily from selection or from the content of the programmes themselves."

"Hundreds, if not thousands, of programs exist to help drive business growth in emerging markets. But what does the evidence actually tell us about whether these programs help businesses grow? And what can practitioners learn from this evidence to design more effective interventions? This knowledge synthesis summarizes the current evidence, identifies gaps in the academic research, and proposes a practitioner-oriented research agenda for the sector."

"We conduct a business plan competition to test whether survey instruments or panel judges are able to identify the fastest growing firms. Participants submitted six- to eight-page business plans and defended them before a three- or four-judge panel. We surveyed applicants shortly after they applied and one and two years after the competition. We use follow-up surveys to construct measures of enterprise growth and baseline surveys and panel scores to construct measures of enterprise growth potential. We find that a measure of ability correlates strongly with future growth, but that the panel scores add to predictive power even after controlling for ability and other survey variables. The survey questions have more power to explain the variance in growth. Participants presenting before the panel were given a chance to win customized management training. Fourteen months after the training, we find no positive effect of the training on growth of the business."

"Management has a large effect on the productivity of medium and large firms. But does management matter in micro and small firms, where the majority of the labor force in developing countries works? We develop 26 questions that measure business practices in marketing, stock-keeping, record-keeping, and financial planning. These questions have been administered in surveys in Bangladesh, Chile, Ghana, Kenya, Mexico, Nigeria, and Sri Lanka. We show that variation in business practices explains as much of the variation in outcomes-sales, profits, and labor productivity and total factor productivity-in microenterprises as in larger enterprises."

"The authors conduct a randomized experiment among women in urban Sri Lanka to measure the impact of the most commonly used business training course in developing countries, the Start-and-Improve Your Business program. They work with two representative groups of women: a random sample of women operating subsistence enterprises and a random sample of women who are out of the labor force but interested in starting a business. They track the impacts of two treatments -- training only and training plus a cash grant -- over two years with four follow-up surveys and find that the short and medium-term impacts differ."

"Business training programs are a popular policy option to improve the performance of enterprises around the world, and the number of rigorous impact evaluations of these programs is growing. A critical review reveals that many evaluations suffer from small sample sizes, measure impacts only within a year of training, and experience problems with survey attrition and measurement that limit the conclusions one can draw. Over these short time horizons, there are relatively modest effects of training on the survivorship of existing firms. However, there is stronger evidence that training programs help prospective owners launch new businesses more quickly. Most studies find that existing firm owners implement some of the practices taught in training, but the magnitudes of the improvement to practices is often modest. Few studies find significant impacts on profits or sales, although some studies with greater statistical power have done so. There is little evidence to guide policymakers regarding whether any identified effects are due to trained firms drawing sales from competing businesses rather than through productivity improvements or to guide the development of the provision of training at market prices. We conclude by summarizing some directions and key questions for future studies."
