"I present a model of financing social enterprises to delineate the role of impact investors relative to "pure" philanthropists. I characterize the optimal scale and structure of a social enterprise when financed by grants and when financed by investments. The analysis yields two heuristics to guide impact investors. First, investments allow a financier to discipline inefficient spending. Second, investments may enable a social enterprise to exploit new opportunities for profit and may increase the enterprise's scale relative to when grant financed. I quantify these heuristics for the case of Husk Power, a social enterprise that has received impact investment."

"This primer provides family enterprises with clear explanations of the "why," "how," and "what" of impact investing. The following pages will illuminate the diversity of the impact investing marketplace as it exists today, and provide families with a basic understanding of how they can start making more impact investments more effectively."

"A commonly held belief among investors is that impact investing-adding environmental, social or governance criteria to the investment selection process-will require a trade-off in performance. Though this may have been true in the early days of impact investing, the space has evolved significantly in the last decade.
In this paper, we will evaluate current impact investing by examining:
- What impact investing is and how it has evolved to be a viable investment approach
- How investors can maintain returns in their portfolios while investing for impact
- How impact investing can be used to identify risks and opportunities in the market
- Historical returns from a range of impact investments
- How investors can start accessing the impact investing marketplace today"

"This report from Oxfam and Sumerian Partners questions some of the assumptions around impact investment and highlights the experience of enterprises contributing to poverty reduction so that they might be better served by the field. It argues that the sector risks being discredited due to rising, unrealistic expectations about financial returns."

"The world is on the brink of a revolution in how we solve society's toughest problems. The force driving this revolution is "impact investing", which harnesses entrepreneurship, innovation and capital to power social progress. This report, Impact Investing: The Invisible Heart of Markets - Harnessing the power of entrepreneurship, innovation and capital for public good, examines what is needed to catalyse the growth of a global market for impact investment. It makes recommendations that can be implemented across Taskforce countries and beyond to deliver better social outcomes and improve millions of lives across the world. The report calls on governments and the financial sector to take action to unleash $1 trillion of private sector impact investment to tackle social problems."

"The study reviews the current state of impact investments in Singapore and Hong Kong, particularly those that have engaged with foundations. It further looks at the trends and challenges of the impact investment sector before presenting a list of recommendations."

"This research note asserts that impact investment, which is intended to create positive social or environmental impact beyond financial return, constitutes a new asset class. The report also includes the first large-scale data analysis of return expectations from more than 1,000 impact investments and compares them to established benchmarks for emerging and developed market debt and equity returns. We hope this report helps to advance a broader understanding of impact investing as an appropriate and economically effective way to complement government and philanthropy in solving the world's greatest problems at scale."

"This paper investigates the impact of investment in human capital (off-the-job training in short term) on productivity of the small and medium enterprises (SMEs) by using Propensity Score Matching (PSM) method with dynamic approach. The paper employs the data from two surveys on the SMEs in Vietnam in the year of 2009 and 2011 that provide detailed information about training and firm characteristics. The results found that training has significantly positive impact on the productivity of household business, but there is no evidence on the impact of training on productivity of the firms in formal sector in the short run; and there is no evidence on the impact of training activities on productivity in the medium run (one-or-two-year after training) for both household business and formal enterprises. Besides, qualitative approach shall be conducted to provide more description on training efficiencies in some specific cases."

"This report is the first follow-up to the impact evaluation of the Kyrgyzstan Women's Leadership in Small and Medium Enterprises (WLSME) activity commissioned by the Office of Gender Equality and Women's Empowerment (GenDev) in the United States Agency for International Development's Bureau for Economic Growth, Education and Environment (USAID/E3). The report summarizes the data collection and analysis methods and provides initial findings and conclusions based on baseline and post-intervention data collection and analysis of the Kyrgyzstan WLSME activity. The impact evaluation plans to collect two more follow-up rounds at 12 months and 24 months post-intervention; thus, this report contains only initial findings that could be observed at the end of the activity."

"In 2015 and 2016, ANDE held roundtables on green inventing in Brazil, India, Kenya, Mexico, and South Africa with a diverse group of participants. The report compiles the findings from these discussions, from desk research, and from interviews with subject matter experts on the areas where invention-based entrepreneurs who promote environmental responsibility require ecosystem-level support in order to succeed."
