This paper analyses investors’ ability to identify if managers use corporate social responsibility as an entrenchment practice to conceal the risk of dismissal associated with managerial discretion and if this detection is determined by the level of investor protection orientation. Results based on an international database of 1949 companies show that investors and markets do not identify managerial entrenchment based on the promotion of sustainable practices, except when such entrenchment is developed by companies located in countries with strong investor protection. In these countries, investors identify and penalise such companies with lower financial performance.
