Corporate Social Responsibility Performance Information and Information Asymmetry

Using Corporate Social Responsibility (CSR) performance scores from KLD STAT, we investigate whether CSR performance affects information asymmetry. We find that both positive and negative CSR performance reduce information asymmetry. Moreover, we find that the influence of negative CSR performance is much stronger than that of positive CSR performance in reducing information asymmetry. We also investigate the effect of informed investors on the CSR performance-asymmetry relation. We find that the negative association between CSR performance and bid-ask spread decreases for firms with a high level of institutional investors compared to those with a low level of institutional investors. This finding suggests that informed investors may exploit their CSR information advantage. Overall, our results suggest that CSR performance plays a positive role for investors by reducing information asymmetry and that regulatory action may be appropriate to mitigate the adverse selection problem faced by less-informed investors
