Abstract

This paper investigates the implications for firm equity value and ownership structure when a large institutional investor publicly excludes a firm from its portfolio due to unethical behaviour. To achieve this, it makes use of the GPFG's ethical exclusions. On average, firms lose 1.72% of equity value around exclusion announcements, which is not reversed in the short term. For firms excluded under the product criteria, the effect seems to be driven by the divesting behaviour of ethics-sensitive investors.
