"This paper identifies separate and unique pathways to profits among small businesses in South Africa that are exposed to marketing or finance training in a randomized control study. The marketing group achieves greater profits by adopting a growth focus on higher sales, greater investments in stock and materials, and hiring more employees. The finance group achieves similar profit gains but through an efficiency focus on lower costs. Both groups show significantly higher adoption of business practices related to their respective training program. Consistent with a growth focus, marketing/sales skills are significantly more beneficial to firm owners who ex ante have less exposure to different business contexts. In contrast and in line with an efficiency focus, entrepreneurs who have been running more established businesses prior to training benefit significantly more from finance/accounting skills."

"This paper examines the impact of improvements in marketing skills relative to finance skills among small-scale entrepreneurs. It addresses three important questions: (1) What is the impact of marketing or finance skills on business profits? (2) How do improvements in marketing and finance skills respectively affect different business outcomes? (3) When are increases in marketing relative to finance skills more beneficial? Through a randomized control study of 852 firms in South Africa, the analysis finds significant improvements in profitability from both types of business skills training. However, the pathways to achieve these gains differ substantially between the two groups. The marketing group achieves greater profits by adopting a growth focus on higher sales, greater investments in stock and materials, and hiring more employees. The finance group achieves similar profit gains but through an efficiency focus on lower costs. Both groups show significantly higher adoption of business practices related to their respective training program. Consistent with a growth focus, marketing/sales skills are significantly more beneficial to businesses run by entrepreneurs with ex ante less exposure to different market contexts. In contrast and in line with an efficiency focus, it is the more established businesses that benefit significantly more from finance/accounting skills."

"This guide aims to help early-stage innovators develop business models and partnership approaches that align with the development of their product, and envision potential pathways for bringing products to scale. While many concepts and insights in this guide apply to all global health innovations, our focus is on medical devices and products, rather than drugs, commodities, or service-delivery models."

"This piece distills critical lessons that cut across geographies and sectors and provides vital information for enterprises and funders trying to unlock impact at scale. Pivoting to Impact builds on in-depth Case Studies that share the scaling journeys of three organizations that have completed their IIA-funded work. Each organization has a unique story to tell about its strategies, pivots, successes, and failures on the road to scale."

"We study the information-gathering role of a startup accelerator and consider the accelerator's incentives to choose a portfolio size and disclose information about participating ventures. We show that in a rational-expectations equilibrium, the resultant portfolio size is smaller than the first-best (efficient) level, consistent with some real-world observations. We further show that when some signals are uninformative and the portfolio consists of mostly high-quality ventures, the accelerator may choose to disclose only positive signals (and conceal negative signals) about its portfolio firms - a strategy we refer to as partial disclosure. Moreover, coupled with pursuing this strategy of partial disclosure, we demonstrate that the accelerator may possess incentives to exit its portfolio firms early."

"The authors set out to document, understand and disseminate good practices in policies for social enterprises, and ultimately to contribute to the development of the sector in Latin America and globally. The book introduces a model of how to position the issue on the public agenda in a way that responds to the most urgent social needs of the country and the sector, building on existing local policies as well as those from other countries, and involving stakeholders in permanent dialogue. The Road to Travel, aimed at public policymakers and key sector players, includes 34 cases of best practices in public policy and a strategy to move faster to address our most intractable problems through a new economy."

"Most impact investors see their primary goal as finding and investing in enterprises that yield strong financial and social returns-a goal we share and support. But we worry this singular focus may miss the forest for the trees. In this discussion paper, we argue for a shift in focus-toward the goal of scaling entire industry sectors, in addition to individual firms."

"Micro, small and medium private and social enterprises (hereafter referred to as 'enterprise') are emerging as important players in enabling or delivering sustainable water, sanitation and hygiene (WASH) services. This area is highly dynamic, thus pointing to a need for recent consolidated evidence about the effectiveness, sustainability and quality of services provided by such enterprises. A synthesis of literature on small-scale sanitation entrepreneurs was conducted in 2008, and at that time reported that the "quality research was relatively scarce, and few good case studies were found" (Valfrey-Visser and Schaub-Jones 2008, p.4). This paper reviews literature over the five years since 2008, once again taking stock and examining the nature and quality of the evidence for private enterprise engagement across both sanitation and water sub-sectors. In particular, we review of the evidence concerning if and how poor households and communities are being supported."

"This book summarizes five years of learning from data collected as part of the Global Accelerator Learning Initiative. The authors present data describing impact-oriented ventures and accelerators that operate in both high-income countries and in emerging markets. Blending survey data with insights from sector experts, their various analyses shed light on the basic structure of accelerators, showing where they are having their most promising results.

Unlike previous studies, this book does not focus on a few high-profile accelerators (like TechStars and Y Combinator) and startups (like AirBnB and Uber). Instead, it compares a range of accelerator programs that target specific impact areas, challenging regions, and marginalized entrepreneurs. Therefore, it serves as a valuable tool for scholars, policymakers, and practitioners interested in the effectiveness of accelerator programs as tools that unleash the economic potential currently trapped in entrepreneurial dead spaces."

"As low-income countries industrialize, workers choose between informal self-employment and low-skill manufacturing. What do workers trade off, and what are the long run impacts of this occupational choice? Self-employment is thought to be volatile and risky, but to provide autonomy and flexibility. Industrial firms are criticized for poor wages and working conditions, but they could offer steady hours among other advantages. We worked with five Ethiopian industrial firms to randomize entry-level applicants to one of three treatment arms: an industrial job offer; a control group; or an "entrepreneurship" program of $300 plus business training. We followed the sample over a year. Industrial jobs offered more hours than the control group's informal opportunities, but had little impact on incomes due to lower wages. Most applicants quit the sector quickly, finding industrial jobs unpleasant and risky. Indeed, serious health problems rose one percentage point for every month of industrial work. Applicants seem to understand the risks, but took the industrial work temporarily while searching for better work. Meanwhile, the entrepreneurship program stimulated self-employment, raised earnings by 33%, provided steady work hours, and halved the likelihood of taking an industrial job in future. Overall, when the barriers to self-employment were relieved, applicants appear to have preferred entrepreneurial to industrial labor."
