This document discusses corporate social responsibility (CSR) in the health sector, particularly as it relates to the pharmaceutical industry. It defines CSR and explores arguments for and against firms engaging in socially responsible behavior. While CSR can increase profits if consumers reward firms for it, information asymmetries and lack of transparency can undermine these incentives. The pharmaceutical industry contributes greatly to public health but suffers from a poor reputation due to issues like lack of drug innovation and pricing practices. Increased transparency through various means may help build trust and a virtuous cycle where "doing good" also leads to "doing well" financially.
