"Impact assessment is a key component of managing an impact investment portfolio, and many investors today are building methodologies that bring value
beyond simply reporting outcomes.

For many investors, the impact goal is the common thread across a portfolio of various sector, geography and instrument types and this diversification can make choosing an impact assessment methodology challenging. As such, the process for developing a methodology is often an iterative one, refined with experience and data over time.

To help inform that iterative process, this research presents sixty-eight case studies from twenty-one leading impact investors that share best practice and
debated viewpoints on impact assessment along the investment process."

"Impact due diligence creates value for a broad range of stakeholders across the impact investing ecosystem, including impact investors, investees and the field at large. Key benefits include fostering internal alignment around intended impacts and priorities, deepening understanding of investees’ activities, supporting the construction of more positively impactful portfolios, improving investor and investees’ ability to communicate impact, strengthening relationships between investees and investors, and increasing firms’ ability to attract additional capital. In combination, the benefits of widespread adoption of impact due diligence should attract additional capital to the field and thereby foster the formation of more inclusive and sustainable financial markets."Impact Due Diligence: Emerging Best Practices" is the first of two reports intended to elevate the practice of impact due diligence."

"This evaluation assesses the impact of International Finance Corporation's (IFC's) Business License Simplification Project in the municipality of Lima, Peru. It reviews two previous evaluations sponsored by IFC and adds new evidence. Under the project, IFC's Foreign Investment Advisory Services (FIAS) worked with the municipality of Lima to reform the administrative process for obtaining a business license in Cercado de Lima, one of 44 districts that comprise metropolitan Lima. According to the municipality, 64 percent of the businesses in this district lacked a business license in 2005, and most of them were microenterprises. The present evaluation conducted an independent review of previous studies, collected additional data, verified the previous findings, and placed the findings in the context of related studies and evaluations. The goal was to take stock of the results, collect and use other evidence, and draw lessons for future IFC and World Bank operations."

"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."
