"In recent years, accelerator programs experienced substantial growth, becoming an important part of the entrepreneurial ecosystems around the world. New ventures that want to participate in such programs must go through a multi-stage and highly competitive process, with only one out of ten applicants being successful. However, our knowledge with regards to the factors that drive the decisions of accelerator programs is limited, and empirical research on this topic is scarce. We hypothesise that the national culture of the founding team can play an important role as a proxy for the unobservable values and the behaviour of the venture founders, and we examine the impact of cultural diversity on the probability of being admitted into an accelerator program. The results show that diversity enhances the probability of being selected. This finding is robust across several specifications, and while accounting for the potential endogeneity of cultural diversity."

"During the five-year period 2012-2017 we ran the Social Entrepreneurship Accelerator at Duke (SEAD), we learned many lessons that we hope other accelerators can benefit from to increase their own effectiveness. This paper describes that learning journey through our top ten lessons."

"The recent emergence of business accelerators around the world has positioned them as a key player in many regional innovation ecosystems. However, significant confusion exists among academics, industry practitioners and policy-makers about what these organizations are. The confusion stems from their association with incubators and from a lack of differentiation among accelerators. As a result of such lack of clear conceptualization academic and other stakeholders risk drawing false conclusions regarding how these organizations fit into different aspects of the regional innovation ecosystem. In this study we use archival and interview data from the Australian context to differentiate accelerators. While we find accelerators that fit the emerging definition of the concept, we also find several that stretch the definition and meaning of 'accelerator'."

"Business training is a widely used development tool, yet little is known about its impact. We study the effects of such a business training program held in Central America. To deal with endogenous selection into the training program, we use a regression discontinuity design, exploiting the fact that a fixed number of applicants are taken into the training program based on a pre-training score. Business training significantly increases the probability that an applicant to the workshop starts a business or expands an existing business. Results also suggest gender heterogeneity as well as the presence of financial constraints."

"This publication identifies ways to catalyse finance for climate technology incubators and accelerators in developing countries. It aims to inform the Green Climate Fund as it develops a request for proposals on climate technology incubators and accelerators. It also aims to inform other financiers and policymakers on opportunities for catalysing financing in this area. It is based on the outputs of a thematic dialogue on incubators and accelerators held in March 2018. It also draws upon an extensive literature review undertaken by these bodies."

"A professor at Brazil’s prestigious Federal University of Viçosa saw a need on campus for an incubator to support technologically-oriented businesses, including agribusinesses. This resulted in the CENTEV Technology Incubator, which is partially funded by the university but which also receives state and private grants. Its function is to nurture entrepreneurs to develop viable technology based businesses by providing them with management assistance and augmenting their technical capabilities with expert academic advice. The incubator’s 24 graduates are still in business, with average revenues of $2.5 million a year."

"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."

"According to our findings, the number of accelerators serving impact enterpriseshas grown rapidly over the last five years (over 70 percent of the accelerators surveyed were founded in 2008 or later). Despite this strong growth, there is only lim-ited research and data-driven analysis of accelerators’ role in the impact invesment ecosystem. This report aims to generate a greater understanding of accelera-tors in that sector and is part of a broader strategy to analyze, evaluate, benchmark,and strengthen accelerators. It is not intended to be a comprehensive evaluation ofimpact accelerators but an initial assessment of the landscape of these organizations."

"Do business accelerators add value? If so, how? We investigate these questions by focusing on Start-Up Chile, a government-backed ecosystem accelerator. Using a regression discontinuity design, we show that entrepreneurship-schooling services of accelerators can significantly increase new venture performance by improving the entrepreneurial capital of participants. We speculate about the existence of four performance-enhancing mechanisms: greater social clout, the provision of an accountability structure that induces entrepreneurs to articulate and reflect about specific strategic tasks, an increase in self-efficacy, and know-how about building a start-up. We find no support for causal effects of basic services of cash and co-working space."

"This report describes the landscape of business incubators and accelerators in the UK, exploring the scale and distribution, both geographically and sectorally."
