分析了1999至2009年间美国上市公司企业社会责任参与的专有数据，发现成功参与后公司有正向异常回报，且治理较差、有社会责任意识的机构投资者更易被参与。
We analyze an extensive proprietary database of corporate social responsibility engagements with U.S. public companies from 1999–2009. Engagements address environmental, social, and governance concerns. Successful (unsuccessful) engagements are followed by positive (zero) abnormal returns. Companies with inferior governance and socially conscious institutional investors are more likely to be engaged. Success in engagements is more probable if the engaged firm has reputational concerns and higher capacity to implement changes. Collaboration among activists is instrumental in increasing the success rate of environmental/social engagements. After successful engagements, particularly on environmental/social issues, companies experience improved accounting performance and governance and increased institutional ownership.
