This Palgrave Pivot aims to build a bridge between corporate social responsibility (CSR) and sustainable finance in financial markets. It investigates classic CSR topics in the light of a modern conception of sustainability. The first part emphasizes four relevant topics in the CSR panorama of financial institutions: banks remuneration practices; human capital disclosure; the impact of environmental performance on banks, and finally, the institutional investors' attitude towards socially responsible investments (SRIs).  The second part explores CSR practices within the financial markets and discusses risk-return profiles of SRI and non-SRI indexes in different time frames.  It investigates whether thematic social responsible funds obtain different risk-return than traditional funds, and finally, assesses whether equity crowdfunding could foster social innovation.  This book is aimed at scholars and students who are interested in social impact investing and practitioners involved in the social impact market.
