Over the last decade, socially responsible investments (SRIs) have become paramount to both professionals and academics. In the aftermath of the financial crisis of 2007-8, practitioners have become much more involved in new financial models that integrate returns and positive social and environmental impacts. The authors argue that previous irresponsible financial models are anachronistic, and propose a new relationship between stakeholder and shareholder. Starting from the mainstreaming of SRI, this book recovers the social function of banks and the innovative role of crowdfunding and venture capital models. The book offers a unified perspective for firm and funder, making it a timely and invaluable read for scholars and practitioners interested in sustainable development and social impact finance.
