Does corporate social responsibility impact equity risk? International evidence
基于52个国家2002-2020年上市公司数据，研究发现企业社会责任评分越高，总风险、系统风险和特质风险越低，且该效应在制度环境较弱、民法系国家、低监管或披露要求国家以及金融危机和新冠期间更显著。
Abstract Based on a large panel of listed firms from 52 countries in the period 2002–2020, we investigate the relationship between corporate social responsibility (CSR) and equity risk. We confirm previous evidence that higher CSR scores are related to lower risk measures, considering all types of risks: total, systematic, and idiosyncratic. Analyzing a large international sample allows us to investigate the role of country and company characteristics in the relationship between CSR scores and risk measures. The risk-reducing effect is more pronounced in weaker institutional environments. It is stronger in civil-law countries, in countries with low security regulation or disclosure requirement levels and where financial information is less widespread. Firms in high impact or high profile industries benefit more from CSR than firms in other industries as do firms that are not cross-listed. The financial crisis has increased the risk-reducing effect of CSR. The main results are confirmed in the COVID-19 period.
