Does CSR Engender Trust? Evidence From Investor Reactions to Corporate Disclosures

We investigate whether a firm's corporate social responsibility (CSR) activities engender investor trust. Motivated by the observation that investor trust facilitates greater informational price efficiency, we address our question by examining the relation between CSR and three dimensions of stock price discovery: (1) the speed with which stock prices reflect earnings news, (2) the level of investor uncertainty around earnings announcements, and (3) earnings response coefficients. We find robust evidence that CSR enhances investor trust in firms. Specifically, we find that firms with more CSR enjoy faster incorporation of earnings news into stock prices, lower investor uncertainty around earnings announcements, and higher earnings response coefficients. Using a regression discontinuity design, we identify the causal effect of CSR on the speed with which stock prices reflect earnings news. Our inferences are robust to controls for characteristics of reported earnings and firms' information environment, as well as alternative measures of CSR.
