Social impact investing is gaining ground as one of the most important investment trends in the world. While the size of the social impact investing market is still relatively small in global terms, momentum continues to grow unabated. Australia in particular is looking to develop a vibrant and transparent social impact investment market. This book considers a number of innovative strategies and pragmatic policy initiatives that can see the social impact investment market flourish in Australia and internationally. The book describes how social impact investing can enter the investment mainstream and how a high-quality regulatory framework governing the measurement, reporting and evaluation of social impact will be critical to building investor confidence and ensuring the credibility, effectiveness, and transparency of this market. It also examines different approaches to measurement and evaluation that will ultimately be critical to the success of this market. The authors also recognise that governments have a pivotal role to play in growing the social impact investing market, not only in its capacity as a market facilitator and regulator but also as an active purchaser of social outcomes. This book will be informative for those who wish to learn more about how governments, private investors, investment intermediaries, social enterprises, service providers and other market participants around the world can work together to initiate and grow a vibrant, transparent and well-functioning social impact investing market
