Anne Tucker recently blogged about the relationship between corporate social performance and corporate financial performance. She discussed the 2009 article “Does it Pay to Be Good?” in which the authors found a small positive effect on financial performance based upon a meta-analysis of 251 effects in 214 manuscripts.
In the course of my summer research, I came across a 2014 working paper entitled “Everybody’s Talking But is Anybody Listening? Stock Market Reactions to Corporate Social Responsibility Communications.” Professors Kun Yu, Shuili Du and C.B. Bhattacharya assert that theirs is the first to examine whether and how the stock market reacts to voluntary non-financial disclosure, namely stand-alone CSR reports. They conclude that non-financial CSR reports “play a critical role in supplementing firm financial disclosure and enhancing information transparency to investors and other important stakeholders.”
For those who aren’t familiar with CSR reports, they typically include information about firm performance in human resources, the environment, corporate governance, suppliers, customers, community engagement, and other relevant factors. Examples of some good CSR reports are here. The study’s sample size consisted of Fortune 500 companies that released CSR reports between 2005-2011– 139 firms with 328 release dates during the relevant period.
