Motivated by agency theory, we explore the effect of corporate governance quality on corporate social responsibility (CSR), using the governance standards provided by Institutional Shareholder Services (ISS). Our evidence reveals that firms with more effective governance make significantly less investment in CSR. It appears that managers tend to over-invest in CSR and are forced to reduce CSR investments when corporate governance is more effective. In particular, an improvement in governance quality by one standard deviation translates into a decline in CSR investments by 7.16%. Our fixed-effects analysis also shows that, within firms, when governance quality improves over time, CSR investments decline significantly. Using the passage of the Sarbanes-Oxley Act of 2002 as an exogenous shock that improves the quality of corporate governance, we demonstrate that high-quality governance is not merely associated with, but rather brings about, lower CSR investments.Mahidol UniversityEconomics, Econometrics and FinanceConference PaperSCOPUS10.1111/ajfs.12121
