Abstract
This study examines whether firms’ corporate social responsibility (CSR) performance affects the informativeness of their earnings conference calls. Controlling for confounding information from earnings releases, we find a positive association between CSR performance and the magnitude of market reactions to conference calls. This association persists after controlling for systematic differences between firms with strong and weak CSR performance. A structural equation model further demonstrates that this positive association is due to firms with strong CSR performance providing a greater amount of information, whereas no evidence suggests that the positive association is attributable to the market perceiving the information to be more credible. We also find incremental effects of managers’ tone and firms’ possession of future unfavorable information on the positive association between CSR performance and the market reactions to the calls. Moreover, CSR performance is associated with reductions in financial analysts’ forecast dispersion. Overall, these results are consistent with the idea that the ethical standards associated with CSR performance promote informative disclosures.

Notes
Similar to these studies, this paper uses the term “CSR performance” to refer to firms’ activities related to CSR.
Some of these studies focus on managers’ tone (e.g., Chen et al., 2018; Davis et al., 2015; Price et al., 2012). Others explore linguistic attributes, such as not answering participants’ questions (Gow et al., 2021; Hollander et al., 2010), scripting (Lee 2016), self-inclusive language (Chen and Loftus 2019), extreme language (Bochkay et al., 2020), and euphemisms (Suslava 2021). These studies provide compelling evidence that the linguistic attributes of conference calls contain valuable information that has subsequent economic consequences, such as impacting stock price movements, influencing analysts’ forecast revisions, and affecting changes in bid-ask spread.
For brevity, we refer to firms with strong CSR performance as CSR firms.
We thank an anonymous reviewer for raising this point.
Consistent with Brochet et al. (2016), we require the occurrence of the conference call to be within the 3-day window around the earnings announcement date.
In untabulated results, we partition the aggregated CSR score into a CSR strengths score (the sum of total CSR strengths) and a CSR concerns score (the sum of total CSR concerns), and find that the magnitude of conference call returns increases with CSR strengths but decreases with CSR concerns.
We note that the number of observations in the treatment group (CSR > 0) and the control group (CSR < = 0) may differ in the final PSM sample due to the requirement of non-missing values for other variables merged into the matched CSR dataset.
The definition of positive words and negative words is based on the word lists from Loughran and McDonald (2011).
Stemming removes the affixes of words and lemmatization uses part-of-speech tapping to identify grammatical categories in order to return the words to proper base form (Bach et al., 2019). While there is an ongoing debate about the suitability of applying these approaches to financial text (Huang et al., 2018; Porter 1980), they are widely employed in financial and accounting research (e.g., Lang and Stice-Lawrence 2015; Li et al., 2021; Merkley 2014). To ensure the robustness of our findings, we conduct tests using both the raw tone measures and the tone measures with the pre-processing techniques.
In Price et al.’s (2012) regression models testing the effect of linguistic tone on market reactions to conference calls, the measures of abnormal return, tone, and earnings surprise are also computed without taking absolute values.
For example, Lee (2016) provides evidence that analysts downgrade their forecasts for firms that use scripted narratives from the presentation session of the conference call when answering participants’ questions. Huang et al. (2018) show that analysts’ interpretation of the information obtained from conference calls helps investors to confirm information they obtained on their own.
