This document discusses concepts and implications of corporate social responsibility (CSR). It outlines key CSR drivers like NGO activism, responsible investment, and litigation that have pushed firms to adopt CSR. Firms now manage CSR through codes of conduct, compliance systems, and reporting to influence their value chains. While CSR may benefit development by improving labor standards and management techniques, some argue it could also suppress jobs and competition in developing countries. Empirical evidence on the economic impacts of CSR is mixed.
