Abstract
There is a growing literature on corporate social responsibility, but few have focused on the implications of business groups for CSR. We examine the antecedents and outcomes of CSR behaviors of group firms in Korea. We find that group affiliation is associated with higher CSR overall and for its major societal and environmental components. However, the ownership disparity between cash flow and control by controlling inside shareholders is associated with lower CSR, consistent with opportunistic rent expropriation theory. We further find that CSR initiatives can impact group firms positively in the event of bad events, consistent with insurance theory. This motive for CSR as a means of enhancing reputation capital to buffer the bad events is pronounced for group firms because of group-wide dissemination of negative reputational externality.
