Common Ownership and Corporate Social Responsibility

Abstract This paper studies the effect of common ownership on corporate social responsibility (CSR). We find that common ownership is positively associated with a firm’s CSR score. The effect is stronger for firms in more competitive industries. We propose a two-stage duopoly game in which CSR serves as a commitment device to expand output aggressively to understand the empirical results.
