This study empirically aims to examine the relation between CEO power and firm engagement in corporate social responsibility (CSR). It undertakes an in-depth analysis of how the structural, ownership and expert dimensions of CEO power affect individual dimensions of CSR.This study uses ordinary least squares and industry fixed-effects regressions. It also uses instrumental variable-generalized method of moment regressions to test the robustness of empirical results. Results indicate that CEO power is negatively related to CSR. However, the relation between CEO power and CSR is influenced by CSR strengths, as power is negatively related to CSR strengths and is not related to CSR concerns. Results also indicate that the structural and ownership dimensions of CEO power are negatively related to CSR, and the expert dimension has no significant effect on CSR. Moreover, results show that CEO power is not related to the product dimension of CSR performance
